ABSTRACT
Introducción: Las fracturas supracondíleas del húmero en el niño, por lo general, son tratadas de manera quirúrgica, durante esa intervención se pueden presentar situaciones específicas en este tipo de enfermos. Objetivo: Actualizar y brindar información sobre algunas de las situaciones transoperatorias en pacientes con fractura supracondílea del húmero. Métodos: La búsqueda y análisis de la información se realizó en un periodo de 61 días (primero de septiembre al 31 de octubre de 2022) y se emplearon palabras de búsqueda relacionadas con la investigación. A partir de la información obtenida, se realizó una revisión bibliográfica de un total de 245 artículos publicados en las bases de datos: PubMed, Hinari, SciELO y Medline, mediante el gestor de búsqueda y administrador de referencias EndNote, de ellos, se utilizaron 29 citas seleccionadas para realizar la revisión, 28 de los últimos cinco años. Resultados: Se hace referencia a cuatro de las situaciones transoperatorias más frecuentes en este tipo de fractura. Se mencionan la conminución de la pared medial, como identificar esta situación y su conducta. En relación a las lesiones asociadas, se recomienda primero estabilizar el antebrazo y luego la fractura supracondílea. Para las fracturas inestables en flexión se recomienda la técnica a emplear. Por su parte, la conversión de la reducción cerrada a abierta está justificada en ciertas circunstancias que de forma detallada se describen en el trabajo. Conclusiones: Las fracturas supracondíleas del húmero en el niño son tratadas en su mayoría mediante tratamiento quirúrgico. Durante el transoperatorio se pueden presentar situaciones para las cuales el médico tratante debe estar preparado.
Introduction: Supracondylar fractures of the humerus in children are generally treated surgically, during surgery intervention may occur specific situations in this type of patient. Objective: To update and provide information on some of the intraoperative situations in patients with supracondylar fracture of the humerus. Methods: The search and analysis of the information was carried out in a period of 61 days (September 1st to October 31st, 2022) and search words related to the investigation were used. Based on the information obtained, a bibliographic review of a total of 245 articles published in the PubMed, Hinari, SciELO and Medline databases was carried out using the EndNote search manager and reference administrator, of which 29 selected citations were used to carry out the review, 28 of the last five years. Results: Reference is made to four of the most frequent intraoperative situations in this type of fracture. Comminution of the medial wall, how to identify this situation and its behavior are mentioned. In relation to associated injuries, it is recommended to first stabilize the forearm and then the supracondylar fracture. For unstable fractures in flexion, the technique to be used is recommended. For its part, the conversion from closed to open reduction is justified in certain circumstances that are described in the article. Conclusions: Supracondylar fractures of the humerus in children are mostly treated by surgical treatment. During the trans-operative period situations may arise for which the treating physician must be prepared.
ABSTRACT
Abstract Objective The aim of this study is to analyze various rehabilitation protocol and determine which methods will yield a better outcome. Methods The database reports were searched within 1990 until 2020, using PubMed, Cochrane library database, Ovid, Medline, and the other several published trials. A statistical analysis was made from Review Manager and Trial Sequential Analysis (TSA). Result The mean of re-rupture rate is 3.3% (n= 8) in the combination protocol until 8% (n= 48) in CAM protocol. Meta-analyses found no significant difference between Kleinert vs CAM in re-rupture rate. Also no significant difference in Duran vs CAM in rerupture rate. In Trial Sequential Analysis (TSA), the z-curve does not cross both of the trial sequential boundaries, a further trial with larger sample will be required. The TSA of flexion contracture CAM vs Kleinert was indicated that CAM protocol may be superior than Kleinert to reduce the incidence of flexion contracture. For the range of mean flexion contracture 6.6% (n= 18) in CAM to 23.6% (n= 76) in Kleinert protocol. Conclusion Current meta-analysis proposed that the combination technique will result less re-rupture incidence and better functional outcome in flexor zone II injuries than other techniques. The CAM method also results less flexion contracture than others. However, a further meta-analyses with larger sample trials will be required to confirm this review's conclusion.
Resumo Objetivo O objetivo deste estudo é analisar vários protocolos de reabilitação e determinar quais métodos produzem um melhor resultado. Métodos Os relatórios dos bancos de dados foram pesquisados entre 1990 e 2020, usando PubMed, banco de dados da biblioteca Cochrane, Ovid, Medline e vários outros ensaios publicados. Uma análise estatística foi feita a partir do Review Manager e Trial Sequential Analysis (TSA). Resultado A taxa média de re-ruptura é de 3,3% (n = 8) no protocolo combinado, e até 8% (n = 48) no protocolo de Movimento Ativo Controlado (MAC). As metanálises não encontraram diferença significativa entre Kleinert vs MAC na taxa de re-ruptura. Também não há diferença significativa entre Duran e MAC na taxa de re-ruptura. Na Trial Sequential Analysis (TSA), a curva z não cruza ambos os limites sequenciais de ensaio, será necessário um ensaio adicional com amostra maior. A TSA de contratura em flexão MAC vs Kleinert indicou que o protocolo MAC pode ser superior ao Kleinert para reduzir a incidência de contratura em flexão. Para a faixa de contratura média em flexão de 6,6% (n = 18) no MAC a 23,6% (n = 76) no protocolo Kleinert. Conclusão A metanálise atual propôs que a técnica combinada resultará em menor incidência de re-ruptura e melhor resultado funcional em lesões da zona flexora II do que outras técnicas. O método MAC também resulta em menos contratura em flexão do que outros. No entanto, serão necessárias mais metanálises com estudos com amostras maiores para confirmar a conclusão desta revisão.

Los desórdenes cerebrovasculares siguen siendo la primera causa de morbilidad y mortalidad neurológica en el mundo, representando una de las entidades patológicas que genera mayor carga de enfermedad a nivel global. La aterosclerosis, o estenosis carotídea, es un potencial factor de riesgo para el ictus isquémico. La identificación y seguimiento estricto de esta condición son esenciales en la prevención secundaria de complicaciones a través de la atención primaria y el manejo especializado del riesgo cardiometabólico. No obstante, dependiendo de este riesgo y/o la presencia de sintomatología, es necesario realizar un manejo definitivo. Actualmente, existe controversia sobre si es mejor tratar la estenosis carotídea asintomática, ya sea médica o quirúrgicamente. Teniendo en cuenta la relevancia de esta entidad, el objetivo de esta revisión consiste en analizar la evidencia reciente sobre el riesgo de ictus isquémico en la aterosclerosis carotídea asintomática en adultos, y el potencial beneficio del manejo quirúrgico vs. farmacológico de esta condición. Para esto, se llevó a cabo una búsqueda bibliográfica en las bases de datos PubMed, ScienceDirect, Web of Science y MEDLINE, hasta el año 2023. Se evidenció que el riesgo de ictus asociado a estenosis carotídea asintomática es significativo (>10 %, aproximadamente), incluso en aquellos con terapia antiplaquetaria e hipolipemiante activa. En aquellos con manejo médico, la supervivencia a cinco años es alrededor del 80 %. Sin embargo, la progresión de la estenosis sucede en promedio en más del 60 % de los casos, y es significativa. Por el contrario, el stent carotídeo y la endarterectomía son intervenciones resolutivas. Pero existe un riesgo mayor comparado con la terapia médica, el cual se atribuye al periodo periy posoperatorio, así como a 30 días de aparición o recurrencia del ictus, infarto agudo de miocardio o muerte por cualquier causa; aunque el uso de la endarterectomía ha demostrado beneficios superiores a largo plazo en cuanto a estos mismos desenlaces. Entonces, la evidencia es heterogénea en cuanto a la superioridad del tratamiento quirúrgico comparado con la terapia farmacológica en el manejo de la aterosclerosis o estenosis carotídea asintomática. Sin embargo, parece ser que el manejo quirúrgico, específicamente la endarterectomía, podría impactar significativamente sobre la aparición o recurrencia del ictus ipsilateral y muerte a largo plazo, pero con resultados controversiales periy postoperatorios.
Cerebrovascular disorders remain the leading cause of neurological morbidity and mortality in the world, representing one of the pathological entities responsible for the greatest burden of disease worldwide. Carotid atherosclerosis or stenosis is a potential risk factor for ischemic stroke. The identification and strict follow-up of this condition are essential in the secondary prevention of complications through primary care and the specialized treatment of cardiometabolic risk. However, depending on this risk and/or presence of symptoms, definitive treatment is necessary. Currently, there is controversy as to whether asymptomatic carotid stenosis is better to be treated medically or surgically. Considering the significance of such entity, this review aims to analyze recent evidence on the risk of ischemic stroke in the case of asymptomatic carotid atherosclerosis among adults, as well as the potential benefit of the surgical vs. pharmacological treatment for this condition. For this purpose, a literature search for publications up to 2023 was carried out in PubMed, ScienceDirect, Web of Science and MEDLINE databases. It was shown that there is a significant risk of stroke associated with asymptomatic carotid stenosis (> 10 % approximately), even in patients with active antiplatelet and lipid-lowering therapy. Out of all those who receive medical treatment, around 80 % had a five-year survival rate. However, stenosis progression occurs on average in more than 60 % of the cases and is significant. On the other hand, carotid stenting and endarterectomy are curative interventions. Nevertheless, these procedures involve a higher risk compared to the medical therapy during the periand postoperative period, as well as 30 days afterwards, due to the occurrence or recurrence of stroke, acute myocardial infarction or death from any cause. Despite this, the use of endarterectomy has shown superior long-term benefits concerning these same outcomes. Thus, evidence regarding the superiority of surgical treatment compared to pharmacological treatment for asymptomatic carotid atherosclerosis or stenosis is heterogeneous. However, it seems that surgical treatment, specifically endarterectomy, could have a significant impact on the occurrence or recurrence of ipsilateral stroke and death in the long term but with controversial periand postoperative outcomes.
ABSTRACT
El adulto mayor, con frecuencia frágil, es un paciente susceptible a un sinnúmero de complicaciones, tanto inmediatas como a corto, mediano y largo plazo, posterior a una intervención quirúrgica. En función de las comorbilidades presentadas, se debe hacer un abordaje integral para alcanzar el mejor estado orgánico previo a la cirugía e intentar mantenerlo durante y posterior a la intervención. Considerar la fuerza estadística de los desenlaces negativos y, específicamente, de la mortalidad en adultos mayores sometidos a cirugía mayor, es verdaderamente un reto. Incluso, esto trasciende a otros campos como la bioética, al plantearse un dilema sobre la distanasia, cuando se recurre a ciertas intervenciones riesgosas en aquellos con un pronóstico de vida temeroso. Recientemente, se ha publicado evidencia interesante que ha estimado la incidencia, riesgo de mortalidad y factores asociados a desenlaces negativos en adultos mayores sometidos a cirugía mayor, planteando posibles modificaciones en los algoritmos de toma de decisiones en futuras guías de práctica clínica en cirugía. El objetivo de esta revisión consiste en analizar evidencia actualizada sobre qué factores de riesgo impactarían más sobre desenlaces negativos y mortalidad en el adulto mayor sometido a cirugía mayor. Se realizó una búsqueda bibliográfica utilizando los términos de búsqueda "Cirugía Mayor" y "Adulto Mayor", además de sinónimos, en las bases de datos PubMed, ScienceDirect, Web of Science y MEDLINE. En cirugía general y subespecialidades, es muy complejo determinar factores de riesgo precisos y extrapolables a todos los escenarios quirúrgicos, debido a la complejidad y especificidad de ciertos órganos y procedimientos. Existe evidencia sobre adultos frágiles que son sometidos a cirugía por cáncer colorrectal, metástasis hepática, cáncer de pulmón, enfermedad pancreática y cáncer esofágico, en donde se registra una mayor estancia hospitalaria; y de forma general, la mortalidad es mayor en aquellos sometidos a cirugía oncológica. No obstante, tanto la integridad física como mental se asocian con peores desenlaces, y la prehabilitación quirúrgica podría impactar de manera positiva sobre esta situación, al mejorar la reserva funcional y tiempo de recuperación posquirúrgico.
The elderly, often frail, are patients susceptible to numerous complications, both immediate and in the short, medium and long term, following surgical interventions. Depending on their comorbidities, a comprehensive approach should be taken to achieve the best condition of the organs prior to surgery and attempt to maintain it during and after the intervention. Considering the statistical strength of negative outcomes, specifically mortality in elderly patients undergoing major surgery, is truly a challenge. This even extends to other fields such as bioethics, raising a dilemma about dysthanasia when resorting to certain risky interventions in those with a fearful life prognosis. Recently, interesting evidence estimating the incidence, mortality risk and factors associated with negative outcomes in elderly patients undergoing major surgery has been published, suggesting possible modifications in decision-making algorithms for future clinical practice guidelines in surgery. The objective of this review is to analyze updated evidence on which risk factors would have the greatest impact on negative outcomes and mortality in elderly patients undergoing major surgery. A literature search was conducted using the search terms "Major Surgery" and "Elderly," in addition to synonyms, in the PubMed, ScienceDirect, Web of Science and MEDLINE databases. In general surgery and subspecialties, it is very complex to determine precise risk factors that can be extrapolated to all surgical scenarios due to the complexity and specificity of certain organs and procedures. Evidence has found that frail adults undergoing surgery for colorectal cancer, liver metastasis, lung cancer, pancreatic disease and esophageal cancer have the longest hospital stays, and overall mortality is higher in those undergoing oncologic surgery. However, both physical and mental integrity are associated with worse outcomes, and surgical prehabilitation could positively impact this situation by improving functional reserve and post-surgical recovery time.
ABSTRACT
ABSTRACT Objectives To evaluate the role of three-dimensional (3D) reconstruction in preoperative planning for complex renal tumors. Materials and Methods A well-planned questionnaire was distributed among the attending urologists at an international meeting. The questionnaire inquired about demographic data, surgical experience, partial nephrectomy (PN) versus radical nephrectomy (RN), surgical approach, time of ischemia, probability of postoperative urine leakage and positive surgical margins after viewing computed tomography (CT) scans and their respective 3D models of six complex renal tumors. Following the CT scans, attendees were asked to view randomly selected reconstructions of the cases. Results One hundred expert urologists participated in the study; 61% were aged between 40 and 60 years. Most of them (74%) were consultants. The overall likelihood of PN after viewing the 3D reconstructions significantly increased (7.1±2.7 vs. 8.0±2.2, p<0.001), the probability of conversion to RN significantly decreased (4.3±2.8 vs. 3.2±2.5, p<0.001), and the likelihood of urine leakage and positive surgical margins significantly decreased (p<0.001). Preference for the open approach significantly decreased (21.2% vs. 12.1%, p<0.001), while selective clamping techniques significantly increased (p<0.001). After viewing the 3D models, low expected warm ischemia time and estimated blood loss were significantly preferred by the respondents (p<0.001). Surgical decision change was significantly associated with performance or participation in more than 20 PNs or RNs annually [3.25 (1.98-5.22) and 2.87 (1.43-3.87), respectively]. Conclusions 3D reconstruction models play a significant role in modifying surgeons' strategy and surgical planning for patients with renal tumors, especially for patients with stronger indications for a minimally invasive and/or nephron-sparing approach.
ABSTRACT
Abstract Objectives To describe a series of cases of tibial fractures surgically treated using the posterior approach as described by Carlson, focusing on evaluating its functional results and complication rate. Methods Eleven patients with tibial plateau fractures, who underwent surgical treatment using the Carlson approach from July to December 2019, were followed-up. The minimum follow-up period was defined as 6 months. The American Knee Society Score (AKSS), American Knee Society Score/Function (AKSS/Function) and the Lysholm score were used to check treatment results at 6 months after the fracture. The patients underwent standard anteroposterior and lateral radiographs to assess fracture healing, and clinical healing was determined by the absence of pain during full weight-bearing. Results The mean follow-up period was 12 months (9-16 months). The primary mechanism of trauma was motorcycle accident, and the most prevalent side of fracture was the right side. Eight participants were male. The mean age of the patients was 28 years. All fractures healed, and none of the patients presented complications. The AKSS was excellent in 11 patients, with a mean AKSS/Function of 99.1±3, and Lysholm scores with a median of 95.0±5.6. Conclusions The Carlson approach for posterior fractures of the tibial plateau can be considered safe, presenting a low complication rate and satisfactory functional results.
Resumo Objetivos O objetivo deste trabalho é descrever uma série de casos de fraturas de tíbia submetidas ao tratamento cirúrgico pela via posterior de Carlson para avaliação de resultados funcionais e frequência de complicações. Métodos Onze pacientes com fraturas do platô tibial foram submetidos a tratamento cirúrgico pela via de Carlson de julho a dezembro de 2019 e acompanhados por um período mínimo de 6 meses. As pontuações American Knee Society Score (AKSS), American Knee Society Score/Function (AKSS/Função) e de Lysholm verificaram os resultados do tratamento 6 meses após a fratura. Os pacientes foram submetidos a radiografias comuns em incidência anteroposterior e de perfil para avaliação da consolidação da fratura e a cicatrização clínica foi determinada pela ausência de dor à descarga total de peso. Resultados O período médio de acompanhamento foi de 12 meses (9 a 16 meses). O principal mecanismo de trauma foi acidente motociclístico e a fratura foi mais prevalente no lado direito. Oito pacientes eram do sexo masculino. A média de idade dos pacientes foi de 28 anos. Todas as fraturas cicatrizaram e nenhum paciente apresentou complicações. A AKSS foi excelente em 11 pacientes, com AKSS/Função média de 99,1 ±3, e a mediana das pontuações de Lysholm foi de 95,0 ±5,6. Conclusões Nas fraturas posteriores do platô tibial, a abordagem de Carlson pode ser considerada segura, apresentando baixo índice de complicações e resultados funcionais satisfatórios.

The patient's correct position is necessary to conduct a safe and effective surgical procedure. This position depends on the access route, duration of the procedure, kind of anesthesia, devices to use, among other factors. This procedure requires planning and effort by the surgical team where they share responsibility to establish and maintain the correct positions for patients. Each surgical position fulfills an objective and implies risks to patients, which is why nursing professionals must be very attentive to provide the necessary care and ensure reliable practices in each position during the perioperative, the importance of the documentation, and the NANDA, NIC, and NOC taxonomy to consider.

ABSTRACT Introduction: The interest in spinal endoscopy is rising, particularly among younger spine surgeons. Formalized postgraduate training programs for endoscopic spinal surgery techniques are lacking behind. Methods: The authors performed a retrospective survey study amongst participants of the 2022 AMCICO endoscopic surgery symposium. Descriptive and correlative statistics were done on the surgeon's responses recorded in multiple-choice questions. In addition, surgeons were asked about their clinical experience and preferences with spinal endoscopy, training background, the types of lumbar endoscopic decompression they perform by approach, and future training requirements. SPSS (version 27) statistical software package was used for data analysis. Descriptive statistic measures were used to count responses and calculate the mean, range, standard deviation, and percentages. In addition, chi-square statistics were used to determine the strength of the association between factors. Results: The online survey was accessed by 321 surgeons, of which 92 completed it (53.4%). Demographic data showed the majority of responding surgeons being orthopedic surgeons (73.6%) and under the age of 50 (69.2%), with over half (51.1%) having less than three months of formalized training in endoscopic spinal surgery techniques. Most surgeons practiced uni-portal (58.9%) versus bi-portal (3.4%) spinal endoscopy. The transforaminal approach (65.5%) was preferred over the interlaminar method (34.4%). The bi-portal technique was indicated almost exclusively for the lumbar spine (94.8%). For endoscopically assisted spinal fusions, a uni-portal approach was preferred by 72% of surgeons over a bi-portal procedure (24.5%). 84.1% of respondents were interested in navigation, of which 30.7% preferred optical over electromagnetic technology (18.2%). Robotics was of interest to 51.1% of survey participants. Respondents' bias was estimated with course attendance assessments, with 37% of surgeons having attended all three days, 27.2% two days, and 16.3% one day. One-fifth of responding spine surgeons did not participate in any curriculum activities but completed the survey. The academic impact of the AMCICO endoscopy symposium was high, with 68.1% of respondents indicating interest in continued training and 61.1% of trainees ready to apply their newly acquired knowledge base to clinical practice. Conclusion: The interest in spinal endoscopy surgery techniques and protocols is high among AMCICO members. Many surgeons are interested in learning advanced endoscopic surgical techniques to integrate the technology into their surgical procedure portfolio to address common painful conditions of the degenerative spine beyond herniated discs and foraminal stenosis. The authors concluded that its academic impact was high based on the responses given by the participating surgeons. Level of evidence III; Retrospective study.
Resumo: Introdução: O interesse em cirurgia endoscópica da coluna tem aumentado especialmente entre os jovens cirurgiões, contudo, são poucos os centros que atualmente oferecem programas de treinamento nesta disciplina. Métodos: Foi realizada uma pesquisa retrospectiva entre os participantes do simpósio de "Cirurgia Minimamente Invasiva e Endoscópica da Coluna Vertebral" realizado durante o Congresso AMCICO 2022. Estatísticas descritivas e testes de correlação foram aplicados às respostas das perguntas de múltipla escolha. Os cirurgiões foram questionados sobre experiência clínica e preferências pela endoscopia espinhal, histórico de treinamento, tipos de descompressão lombar endoscópica que realizaram e requisitos futuros para um treinamento adicional. O software estatístico SPSS (versão 27) foi utilizado para a análise de dados. As medidas estatísticas descritivas foram utilizadas para quantificar as respostas e calcular a mediana, a média, o desvio padrão e as porcentagens. O qui-quadrado foi empregado para determinar a associação entre os fatores estudados. Resultados: A pesquisa on-line foi visualizada por 321 cirurgiões, dos quais 92 a completaram (53,4%). As informações demográficas mostraram que a maioria dos participantes são cirurgiões ortopédicos (73,6%) e menores de 50 anos (69,2%), com mais da metade deles (51,1%) possuindo menos de 3 meses de treinamento formal em técnicas endoscópicas. A maioria dos cirurgiões pratica abordagens uniportais (58,9%, contra 3,4% bi-portais). A abordagem transforaminal (65,5%) foi preferida em relação à abordagem interlaminar (34,4%). A abordagem biportal foi selecionada como a abordagem indicada para a região lombar (94,8%). Para a fusão endoscopia-assistida, a abordagem unilateral foi preferida por 72% dos participantes contra a abordagem biportal (24,5%). Os sistemas de navegação foram de interesse para 84,1% dos participantes, dos quais 30,7% responderam que preferiam a óptica em vez da eletromagnética (18,2%). O uso da robótica foi de interesse para 51,1% dos participantes. O viés dos participantes foi calculado com base no percentual de participação, onde 37% participaram de todos os 3 dias de conferências, 27,2% participaram de 2 dias e 16,3% participaram de apenas um dia. Um quinto dos cirurgiões não participaram das atividades do simpósio e ainda assim responderam à pesquisa. O impacto acadêmico do simpósio de "Cirurgia Minimamente Invasiva e Endoscópica da Coluna Vertebral" foi alto, com 68,1% dos participantes respondendo que têm interesse em treinamento adicional nestas técnicas e 61,1% respondendo que estão prontos para aplicar novos conhecimentos em sua prática médica. Conclusão: O interesse em técnicas cirúrgicas endoscópicas da coluna vertebral é alto entre os membros da AMCICO. Um grande número de cirurgiões está interessado em aprender técnicas cirúrgicas endoscópicas avançadas da coluna vertebral e integrar esta tecnologia como parte de suas ferramentas cirúrgicas para resolver problemas comuns que afetam a coluna com doença degenerativa, além de hérnias de disco e estenoses foraminais. Baseados nas respostas fornecidas pelos cirurgiões participantes, os autores concluem que o impacto acadêmico foi elevado. Nível de evidência III; Estudo retrospectivo.

ABSTRACT Objective The ceramic-on-metal (CoM) bearing has the theoretical advantages over ceramic-on-ceramic (CoC) and metal-on-metal bearings. This study aimed to analyze factors affecting the metal ion release of CoM bearings and compare clinical performance with CoC bearings. Methods The 147 patients were divided into 96 patients in group 1 (CoM group) and 51 patients in group 2 (CoC group). Additionally, within group1, 48 patients and 30 patients were sub-categorized into group 1-A with leg length discrepancy (LLD) less than 1cm and group 1-B greater than 1 cm. The level of serum metal ions, functional scores and plain radiographs were obtained for the analysis. Results The level of cobalt (Co) 2-years after surgery and chromium (Cr) 1-year after surgery showed significantly higher in the group1 than the group2. LLD indicated statistically significant positive correlation between serum metal ion levels among CoM bearing THAs. In comparison of the average metal ions level changes, group 1-B showed higher level of metal ion than group 1-A. Conclusion In patients underwent THA with CoM bearings, large LLD have a higher risk of complications associated to metal ions. Therefore, it is critical to reduce the LLD to 1 cm or less in using CoM bearing. Level of Evidence III; Case Control Study.
RESUMO Objetivo Uma superfície metalocerâmica (CoM) apresenta vantagens teóricas sobre as superfícies cerâmica-cerâmica (CoC) e metal-metal. Este estudo teve como objetivo analisar os fatores que afetam a liberação de íons metálicos das superfícies CoM e comparar o desempenho clínico com as superfícies CoC. Métodos Os 147 pacientes foram divididos em 96 pacientes no grupo 1 (grupo CoM) e 51 pacientes no grupo 2 (grupo CoC). No grupo 1, 48 pacientes foram subcategorizados em grupo 1-A, com discrepância de comprimento das pernas (LLD) menor que 1 cm; e 30 pacientes no grupo1-B maior que 1 cm. O nível de íons metálicos séricos, escores funcionais e radiografias foram obtidas para a análise. Resultados Os níveis de cobalto (Co) 2 anos após a cirurgia e de cromo (Cr), após o primeiro ano da cirurgia mostraram-se significativamente mais altos no grupo 1 do que no grupo 2. A LLD indicou correlação positiva estatisticamente significativa entre os níveis de íons do soro metálico entre os portadores de THA de CoM. Em comparação com as alterações médias dos níveis de íons metálicos, o grupo 1-B revelou um nível de íons metálicos mais alto do que o grupo 1-A. Conclusão Em pacientes submetidos a THA com superfícies CoM e elevada LLD têm um maior risco de complicações associadas a íons metálicos. Sendo fundamental reduzir LLD para 1 cm ou menos no uso de superfícies CoM. Nível de Evidência III; Estudo de Controle de Caso.
ABSTRACT
ABSTRACT Distal femoral metaphyseal fractures are rare in children, and the proximity of the fracture to the growth plate makes their approach challenging. Objective Evaluate outcomes and complications of treatment of distal femoral metaphyseal fractures in children with proximal humeral locking plates. Method Retrospective study between 2018 and 2021, including seven patients. The analysis included general characteristics, trauma mechanism, classification, clinical and radiographic outcomes, and complications. Results The mean follow-up was 20 months, the average age was nine years, five patients were boys, and six fractured on the right side. Five fractures were caused by car accidents, one by falling from their own height and one by playing soccer. Five fractures were classified as 33-M/3.2 and two as 33-M/3.1. Three fractures were open, Gustilo IIIA. All seven patients recovered mobility and resumed their pre-trauma activities. All seven healed, and one fracture was reduced to 5 degrees valgus, without any other complications. Six patients had the implant removed and did not present refracture. Conclusion Treatment of distal femoral metaphyseal fractures with proximal humeral locking plates is a viable option that offers good results and fewer complications, saving the epiphyseal cartilage. Level of Evidence II; Controlled study without randomization.

Conclusão O tratamento das fraturas da metáfise distal do fêmur com placas de úmero proximal é uma opção viável que oferece bons resultados com poucas complicações, poupando a cartilagem epifisária. Nível de Evidência II; Estudo controlado sem randomização.
ABSTRACT
ABSTRACT Objective Latarjet procedure is often preferred in recurrent shoulder dislocations accompanied by glenoid bone loss. It is observed that the superiority of bone graft fixation methods is still controversial. The aim of this study is to biomechanically compare the bone graft fixation methods in the Latarjet procedure. Methods 15 third-generation scapula bone models were divided into 3 groups. Graft was fixated in the first group with fully-threaded cortical screws of 3.5mm diameter, in the second group two 16 mm partially-threaded cannulated screws of 4.5mm diameter, and in the third group via a mini plate and screw. The hemispherical humeral head was placed on the tip of the cyclic charge device, and thus, the charge applied to the coracoid graft was homogeneous. Results No statistically significant difference was found between paired comparisons (p>0.05). The forces in 5 mm displacement in total vary between 502-857N. Total stiffness measurements ranged between 105 and 625; the mean value was 258.13±53.54 with no statistically significant difference by groups (p = 0.958). Conclusion This biomechanical study showed that there is no difference between three coracoid fixation options in terms of fixation strength. Unlike previous assumptions, plate fixation is not biomechanically superior to screw fixation. Surgeons should consider their personal preferences and experience in choosing fixation methods.
RESUMO Objetivo O procedimento Latarjet é normalmente preferencial em deslocamentos recorrentes do ombro acompanhados por perda óssea da glenóide. Observa-se que a superioridade dos métodos de fixação dos enxertos ósseos ainda é controversa. O objetivo deste estudo é comparar biomecanicamente os métodos de fixação de enxerto ósseo no procedimento Latarjet. Métodos 15 modelos de escápulas de terceira geração foram divididos em 3 grupos. O enxerto foi fixado no primeiro grupo com parafusos corticais totalmente rosqueados com 3,5 mm de diâmetro, no segundo grupo com dois parafusos canulados parcialmente rosqueados de 16 mm de diâmetro de 4,5 mm e no terceiro grupo através de miniplaca e parafuso. A cabeça hemisférica umeral foi colocada na ponta do dispositivo de carga cíclica e, desta forma, a carga aplicada ao enxerto coracoide foi homogênea. Resultados Nenhuma diferença estatisticamente significativa foi encontrada entre as comparações pareadas (p>0,05). As forças em 5 mm de deslocamento no total variam entre 502-857N. As medidas de rigidez total variaram entre 105 e 625 e o valor médio foi 258,13±53,54, sem diferença estatisticamente significativa por grupos (p = 0,958). Conclusão Este estudo biomecânico mostrou que não há diferença entre três opções de fixação de coracoides em termos de resistência à fixação. Ao contrário de suposições anteriores, a fixação de placas não é biomecanicamente superior à fixação de parafusos. Os cirurgiões devem considerar suas preferências pessoais e sua experiência na escolha de métodos de fixação.
ABSTRACT
Introducción: El hematoma subdural crónico es la complicación tardía más frecuente del trauma craneoencefálico. Su diagnóstico precoz y el tratamiento oportuno permiten la evolución favorable y curación de los pacientes. Objetivo: Sistematizar los diferentes ejes de clasificación del hematoma subdural crónico, que permitan la evaluación multimodal con una orientación más precisa de la técnica quirúrgica. Métodos: Se realizó una revisión bibliográfica en las principales bases de datos disponibles, centrada en las diferentes clasificaciones clínicas y radiológicas del hematoma subdural crónico y se seleccionaron 26 artículos. Se escogieron las principales clasificaciones y escalas y se aplicaron en 22 pacientes, obteniéndose resultados preliminares. Resultados: Las escalas de evaluación clínica de Bender, Marckwalder y la clasificación de Gordon Firing son las más conocidas, sin embargo, existen clasificaciones tomográficas que tienen en cuenta la densidad, la homogeneidad del hematoma que son de gran importancia en la selección de la técnica quirúrgica. La presencia de membranas y tabiques aparecen solo incluidas dentro de la valoración de la densidad del hematoma. Existen otras con valor predictivo que identifican aquellos factores relacionados con las recurrencias, desde antes de la cirugía, las mismas se consideran un factor de mal pronóstico para la evolución final de los pacientes con este tipo de hematomas. Conclusiones: La evaluación preoperatoria exige de la aplicación de múltiples escalas, la identificación y caracterización de las membranas es importante para personalizar la técnica quirúrgica, en busca de disminuir la morbilidad y mortalidad posoperatoria.
Introduction: Chronic subdural hematoma is the most frequent late complication of cranioencephalic trauma. The early diagnosis and correct treatment allow the recovery of patients. Objective: To systematize the different criteria of classification of chronic subdural hematoma that leads the multimodal evaluation for more effective selection of surgical technique. Methods: A review of literature about chronic subdural hematoma was done in the main database focused on different clinical and radiological classifications and 26 articles were selected. The main classifications and scales were chosen and applied to 22 patients, obtaining preliminary results. Results : Benders, Marckwalder and Gordon Firing scales are the most common, nevertheless there are tomographic classifications that include density, homogeneity of hematoma that are of great importance in the selection of the surgical technique. The presence of membranes and septum are only included in the evaluation of hematoma density. There are some others with predictive value that identify those factors related to recurrences before surgery that are considered a bad prognosis to the final evolution of these patients with this type of hematoma. Conclusions: The previous evaluation to surgery requires the use of different scales, the identification and characterization of membranes are important to select the optimum surgical technique to decrease morbidity and mortality after surgery.
ABSTRACT
ABSTRACT Objective: to describe the current scope of certified trauma surgeons trained in the state of Rio Grande do Sul, including demographic data, geographic distribution, remuneration, and perspectives related to this specialty. Method: cross-sectional survey based on information collected through an electronic questionnaire sent to potential participants. Results: the response rate was 64% (n=75). There was a predominance of males (72%) with a mean age of 43 years. Most surgeons graduated from the Hospital de Pronto Socorro de Porto Alegre, and work in referral centers for trauma surgery in the capital and metropolitan region. More than 60% did not have any other training in a surgical subspecialty, though only a third stated that trauma surgery is their main source of income. Conclusion: trauma centers are poorly distributed and most surgeons work in referral hospitals in the metropolitan region of Porto Alegre. Due to the lack of recognition, limited financial income and shift work patterns, the career in trauma surgery care is unattractive, with only one third of surgeons performing most of their activities in this specialty.
RESUMO Objetivo: descrever o perfil dos cirurgiões do trauma formados no estado do Rio Grande do Sul, incluindo dados demográficos, distribuição geográfica, remuneração, e perspectivas relacionadas à área de atuação. Método: estudo transversal do tipo inquérito, baseado em informações coletadas por meio de questionário enviado via plataforma digital para os profissionais da amostra em questão. Resultados: a taxa de resposta dos questionários foi de 64% (n=75). Houve predomínio do sexo masculino (72%) com idade média de 43 anos. A maior parte dos profissionais foi graduada pelo Hospital de Pronto Socorro de Porto Alegre, e atua em serviços de referência em Cirurgia do Trauma na capital e região metropolitana. Mais de 60% não realizou outra formação em subespecialidade cirúrgica, embora apenas um terço dos profissionais tenha declarado que a Cirurgia do Trauma seja sua principal fonte de renda. Conclusão: os centros de trauma são mal distribuídos e a maioria dos profissionais atua em hospitais de referência da região metropolitana de Porto Alegre. Devido ao baixo reconhecimento, incentivo financeiro limitado e desgaste da modalidade de trabalho em regime de plantão, a carreira com dedicação exclusiva na área de Cirurgia do Trauma é pouco atrativa, com apenas um terço dos profissionais desempenhando a maior parte de suas atividades na área.
ABSTRACT
ABSTRACT Pediatric surgery receives great demand for referrals from primary care services in order to evaluate the need for surgical intervention. However access to this specialized evaluation and in intervention does not always occur at the appropriate time. This study aims to characterize the profile of pediatric patients electively operated in the western Paraná state region, between 2018 and 2020, and identify those who were lately referred to surgical evaluation. This is a descriptive, cross-sectional and retrospective study through the review of electronic medical records. The variables evaluated were sociodemographic data, information on underlying diseases, referral data, specialist assessment and surgical procedure. During this period, 410 patients underwent an elective surgical procedure, of which 289 were included in the research. The sample was predominantly male (72.3%) with a mean age of 57.9 months at the surgeons assessment and 59 months at the date of surgery. Most of the patients came from primary care (75%) and the most common pathology was inguinal hernia (39.1%). The mean time interval between referral through primary care and surgery was 4.98 months, and between the surgeons assessment and surgery was 1.21 months. Of the total sample, 77 (26.6%) patients were identified as being referred late for the surgical procedure. Knowing the profile of patients and the problems experienced in this region in relation to the care provided in pediatric surgery provides subsidies to propose improvement strategies not only for the health system in this location, but for several inner regions of Brazil in a similar situation.
RESUMO Introdução: a cirurgia pediátrica representa especialidade com demanda significativa de encaminhamentos dos serviços de atenção primária para avaliação da necessidade de intervenção cirúrgica. Contudo, nem sempre o acesso a essa intervenção ocorre no momento adequado. Nesse sentido, objetivou-se caracterizar o perfil dos pacientes pediátricos operados eletivamente, no recorte temporal 2018-2020, e identificar pacientes que foram encaminhados em atraso para a avaliação com o cirurgião. Métodos: Estudo descritivo, transversal e retrospectivo mediante a revisão de prontuários eletrônicos. As variáveis avaliadas foram dados sociodemograficos, informações das doenças de base, dados do encaminhamento, da avaliação do especialista e do procedimento cirúrgico. Resultados: neste período 410 pacientes foram submetidos a procedimento cirúrgico eletivo, dos quais 289 foram incluídos na pesquisa. O sexo masculino (72,3%%) foi predominante, com idade média de 57,9 meses na avaliação pelo cirurgião e 59 meses na data da cirurgia. A procedência dos pacientes foi na maioria da atenção básica (75%) e a patologia mais incidente foi a hérnia inguinal (39,1%). O intervalo de tempo médio entre o encaminhamento pela atenção primária até a realização da cirurgia foi 4,98 meses e entre a avaliação pelo cirurgião e a realização da cirurgia foi 1,21 meses. Do total, 77 (26,6%) pacientes foram identificados como encaminhados em atraso para a realização do procedimento cirúrgico. Conclusão: conhecer o perfil dos pacientes e os problemas vivenciados nesta região em relação aos atendimentos prestados na cirurgia pediátrica apresenta subsídios para propor estratégias de melhoria não só do sistema de saúde local, mas de diversas regiões interioranas do Brasil em situação semelhante. .
ABSTRACT
ABSTRACT Objective: Arthrodesis techniques such as anterior lumbar interbody fusion (ALIF) and lateral lumbar interbody fusion (LLIF) aim to reestablish physiological lordosis and minimize tissue damage to the paravertebral musculature. Supplementation with percutaneous pedicle screws is indicated in most cases, therefore, intraoperative changes in decubitus are necessary, generating costs and risks for the patient. This study aims to present concepts and results of a series of 100 cases of patients undergoing 360° fusion in lateral single position surgery (LSPS). Methods: retrospective analysis of databases collected between 2016 and 2021. Patients who underwent 360° fusion of the lumbar spine in single lateral decubitus to treat degenerative and infectious diseases were included. Cases with arthrodesis greater than 3 levels were excluded. Data collected include demographics, body mass index (BMI) and scores such as visual analog scale (VAS), EuroQOL 5D (EQ5D) and Oswestry disability index (ODI). Results: 100 patients were included in the study, submitted to LLIF and/or ALIF associated with percutaneous pedicle fixation. The lumbar VAS improved from 6.75 to 2.1 after 12 months, while the sciatica VAS started from 4.55 and reached 0.81 after one year. The EQ5D improved from 66.1 to 81.6 after the first year, while the ODI ranged from 28.54 to 14.18 in the same period. Conclusions: the clinical-functional results of the LSPS procedures are favorable and place the LSPS as an option to be studied, developed and practiced by spine surgery teams. Level of evidence: IV. Case series.
Resumo: Objetivo: Técnicas de artrodese como anterior lumbar interbody fusion (ALIF) e lateral lumbar interbody fusion (LLIF) tem como objetivos o reestabelecimento da lordose fisiológica e a mínima lesão tecidual da musculatura paravertebral. A suplementação com parafusos pediculares por via percutânea é indicada na maioria dos casos, sendo, portanto, necessárias mudanças de decúbito intraoperatórias, gerando custos e riscos para o paciente. Este estudo tem como objetivo apresentar conceitos e resultados de uma série de 100 casos de pacientes submetidos a fusão 360° em lateral single position surgery (LSPS). Métodos: análise retrospectiva de banco de dados coletados entre 2016 e 2021. Foram incluídos pacientes submetidos a fusão 360° da coluna lombar em decúbito lateral único para tratamento doenças degenerativas e infecciosas. Foram excluídos casos com artrodeses maiores que 3 níveis. Os dados coletados incluem demografia, índice de massa corpórea (IMC) e scores como visual analog scale (VAS), EuroQOL 5D (EQ5D) e Oswestry disability index (ODI). Resultados: 100 pacientes foram incluídos no estudo, submetidos a LLIF e/ ou ALIF associados a fixação pedicular percutânea. O VAS lombar apresentou melhora de 6,75 para 2,1 após 12 meses, já o VAS ciatalgia partiu de 4,55 e atingiu 0,81 após um ano. O EQ5D apresentou melhora de 66,1 para 81,6 após o primeiro ano, enquanto o ODI variou de 28,54 para 14,18 no mesmo período. Conclusões: os resultados clínico-funcionais dos procedimentos em LSPS se mostram favoráveis e a colocam o LSPS como uma opção a ser estudada, desenvolvida e praticada pelas equipes de cirurgia de coluna. Nível de evidência: IV. Série de casos.

Objective:To compare the efficacy of 3D-printed guide plate assisted versus freehand placement of cannulated screws for the treatment of Sanders type II and III calcaneal fractures.Methods:A retrospective cohort study was conducted to analyze the clinical data of 29 patients with Sanders type II and III calcaneal fractures admitted to Chonggang General Hospital from June 2020 to October 2022. Among them, there were 18 males and 11 females, with an age range of 22-69 years [(40.1±11.5)years]. Nineteen patients were treated with individualized 3D-printed guide plate assisted placement of cannulated screws (3D-printed group) and 10 were treated with freehand placement of cannulated screws (freehand group). The surgical time, fluoroscopy times, postoperative 6-month calcaneal morphology (length, width, height, B?hler angle and Gissane angle), and American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and Maryland functional score assessed at 3, 6 months after operation and at the final follow-up were compared between the two groups. The incision healing and complications were observed.Results:The patients were followed up for 6-24 months [(11.3±2.5)months]. The surgical time and fluoroscopy times in the 3D-printed group were (53.4±9.1)minutes and (7.3±1.1)times, respectively, which were shorter than (90.2±16.0)minutes and (16.0±3.2)times in the freehand group (all P<0.01). At 6 months after operation, there was no significant difference in calcaneal length between the two groups ( P>0.05); the calcaneal width, height, B?hler angle and Gissane angle in the 3D-printed group [(34.0±1.8)mm, (47.2±1.6)mm, (27.8±1.0)°, (129.2±2.8)°] were superior than those in the freehand group [(37.5±2.0)mm, (43.0±2.7)mm, (25.8±1.5)°, (125.9±2.5)°] (all P<0.01). At 3, 6 months after operation and at the final follow-up, the values of AOFAS ankle-hindfoot score in the 3D-printed group [(72.2±2.3)points, (79.7±2.3)points, (86.5±4.4)points] were higher than those in the freehand group [(64.2±6.9)points, (73.4±4.2)points, (81.8±3.1)points] (all P<0.05); the values of Maryland score in the 3D-printed group [(71.4±7.7)points, (84.7±2.6)points, (91.5±2.5)points] were higher than those in the freehand group [(65.2±5.6)points, (79.1±3.8)points, (87.1±2.9)points] (all P<0.05). All surgical incisions were healed in stage I. In the 3D-printed group, there were no complications regarding infection, iatrogenic vascular or nerve injury, or fixation failure after surgery. In the freehand group, one patient with lateral sural cutaneous nerve injury was resolved spontaneously without specific treatment. Conclusion:Compared with freehand placement of cannulated screws, 3D-printed guide plate assisted placement of percutaneous placement has the advantages of shorter surgical time, fewer fluoroscopy times, lower reduction loss, better ankle joint function recovery, and less complications in treating Sanders type II and III calcaneal fractures.
ABSTRACT
Post-traumatic osteoarthritis (PTOA) refers to the degeneration and destruction of cartilage after trauma to joints and surrounding tissues, along with the damage of subchondral bone, synovium, capsule, muscles and ligaments, finally resulting in osteoarthritis and dysfunction. PTOA of the knee mainly manifests as pain, stiffness and impairment of motion capacity. Management of PTOA includes physical therapy, medication and surgical intervention. Despite the pain was temporarily relieved, the long-term prognosis is still not satisfactory after medication and physical therapy. Surgical intervention is strongly recommended for the moderate and advanced stages of PTOA, which includes arthroscopic debridement, repair of cartilage, osteotomy and arthrodesis. For terminal PTOA, total knee arthroplasty (TKA) is necessary. However, TKA in the treatment of PTOA is challenging, especially for patients with surgical history, poor soft tissue conditions, abnormal alignment, multiple complications, as well as individual variation. Up to now, there is still a lack of standards and consensus for TKA in the treatment of PTOA. Accordingly, the author discusses the issues related to TKA in the treatment of PTOA, aiming to provide a reference for the treatment of PTOA of the knee.
ABSTRACT
Objective:To explore the outcome of sponge forceps assisted threading with Speedbridge technique for the treatment of acute closed Achilles tendon rupture.Methods:A retrospective case series study was conducted on 20 patients with acute closed Achilles tendon rupture treated in Zhengzhou Orthopedic Hospital from December 2019 to December 2021. There were 18 males and 2 females, with age range of 24-43 years [(29.5±7.6)years]. All patients were with unilateral injury, involving the left side in 13 patients and right side in 7. Examinations revealed a palpable defect in the Achilles tendon and positive Thompson test. A longitudinal incision was made at the medial edge of the ruptured tendon. Three nonabsorbable sutures were passed through the proximal stump with sponge forceps, bypassed the rupture site and fixed directly into the calcaneal bone. The disrupted tendon ends were aligned by the tendon-bundle technique using 4-0 absorbable sutures. The operation time and incision length were documented. The ankle joint range of motion (dorsiflexion/plantar flexion), American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and Achilles tendon total rupture score (ATRS) in the affected and healthy side were compared at 3, 6 and 12 months postoperatively. The wound healing and complications were observed.Results:All patients were followed up for 12-16 months [(13.2±2.5)months]. The operation time was 40-66 minutes [(52.0±10.3)minutes], with the incision length of 3-4 cm [(3.3±0.7)cm]. In the affected side at 3 and 6 months postoperatively, the ankle joint dorsiflexion [(5.6±1.5)°, (10.5±0.2)°] and plantar flexion [(28.4±3.2)°, (33.5±1.5)°] showed statistically significant difference compared with the healthy side (all P<0.05). The ankle joint dorsiflexion [(13.9±0.7)°] and plantar flexion [(38.3±4.4)°] in the affected side were not statistically different from that of the healthy side at 12 months postoperatively (all P>0.05). The AOFAS ankle-hindfoot score was (58.3±5.4)points, (84.9±7.1)points and (91.8±6.3)points at 3, 6 and 12 months postoperatively, showing a gradual rise (all P<0.05). The ATRS was (60.5±4.9)points, (85.5±9.0)points and (93.1±5.7)points at 3, 6 and 12 months postoperatively, showing a gradual rise (all P<0.05). All incisions were healed primarily. No patients had wound infection, nerve injury or re-rupture. Pain at the anchor insertion site occurred in 2 patients at 1 month after operation and relieved after active functional rehabilitation at 4 months after operation. Transient pain at the Achilles tendon insertion occurred in 1 patient at 6 months after operation, and relieved after 2 weeks of oral non-steroidal anti-inflammatory drugs treatment. Conclusion:For acute closed Achilles tendon rupture, sponge forceps assisted threading with Speedbridge technique can attain short operation time, small incision and good functional recovery, with few complications.
