ABSTRACT

OBJECTIVE@#To compare the role and importance of fibular fixation in tibiofibular fractures by Meta-analysis.@*METHODS@#The literature related to the comparison of the efficacy of fixation of the fibula with or without fixation on the treatment of tibiofibular fractures was searched through the databases of China Knowledge Network, Wipu, Wanfang, The Cochrane Library, Web of science and Pubmed, and statistical analysis was performed using RevMan 5.3 software. The rates of malrotation, rotational deformity, internal/external deformity, anterior/posterior deformity, non-union, infection, secondary surgery and operative time were compared between the fibula fixation and non-fixation groups.@*RESULTS@#A total of 11 publications were included, six randomised controlled trials and five case-control trials, eight of which were of high quality. A total of 813 cases were included, of which 383 were treated with fibula fixation and 430 with unfixed fibulae.Meta-analysis results showed that fixation of the fibulae in the treatment of tibiofibular fractures reduced the rates of postoperative rotational deformity[RR=0.22, 95%CI(0.10, 0.45), P<0.000 1] and internal/external deformity[RR=0.34, 95%CI(0.14, 0.84), P=0.02] and promoted fracture healing [RR=0.76, 95%CI(0.58, 0.99), P=0.04]. In contrast, the rates of poor reduction [RR=0.48, 95% CI(0.10, 2.33), P=0.36], anterior/posterior deformity[RR=1.50, 95%CI(0.76, 2.96), P=0.24], infection[RR=1.43, 95%CI(0.76, 2.72), P=0.27], secondary surgery[RR=1.32, 95%CI(0.82, 2.11), P=0.25], and operative time[MD=10.21, 95%CI(-17.79, 38.21), P=0.47] were not statistically significant (P>0.05) for comparison.@*CONCLUSION@#Simultaneous fixation of the tibia and fibula is clinically more effective in the treatment of tibiofibular fractures.

ABSTRACT

OBJECTIVE@#To summarize the research progress on the mechanism related to traumatic brain injury (TBI) to promote fracture healing, and to provide theoretical basis for clinical treatment of fracture non-union.@*METHODS@#The research literature on TBI to promote fracture healing at home and abroad was reviewed, the role of TBI in fracture healing was summarized from three aspects of nerves, body fluids, and immunity, to explore new ideas for the treatment of fracture non-union.@*RESULTS@#Numerous studies have shown that fracture healing is faster in patients with fracture combined with TBI than in patients with simple fracture. It is found that the expression of various cytokines and hormones in the body fluids of patients with fracture and TBI is significantly higher than that of patients with simple fracture, and the neurofactors released by the nervous system reaches the fracture site through the damaged blood-brain barrier, and the chemotaxis and aggregation of inflammatory cells and inflammatory factors at the fracture end of patients with combined TBI also differs significantly from those of patients with simple fracture. A complex network of humoral, neural, and immunomodulatory networks together promote regeneration of blood vessels at the fracture site, osteoblasts differentiation, and inhibition of osteoclasts activity.@*CONCLUSION@#TBI promotes fracture healing through a complex network of neural, humoral, and immunomodulatory, and can treat fracture non-union by intervening in the perifracture microenvironment.

ABSTRACT

OBJECTIVE@#To assess the effectiveness of the single Kocher-Langenbeck approach combined with anterograde channel screw technique for the treatment of acetabular transverse and posterior wall fractures.@*METHODS@#Between March 2020 and October 2022, 17 cases of acetabular transverse and posterior wall fractures were treated with the single Kocher-Langenbeck approach combined with anterograde channel screw technique. There were 11 males and 6 females, with an average age of 53.6 years (range, 42-64 years). Causes of injury included traffic accident in 12 cases, and falling from height in 5 cases. The time from injury to operation ranged from 4 to 16 days with an average of 8.8 days. The operation time, intraoperative blood loss, and fluoroscopy frequency were recorded; X-ray films were reviewed regularly after operation to observe the fracture healing, and postoperative complications were recorded. At last follow-up, Matta score was used to evaluate the reduction of fracture, Harris score and modified Merle D'Aubigné-Postel scores system were used to evaluate the hip joint function.@*RESULTS@#The operation time was 150-230 minutes (mean, 185.9 minutes), the intraoperative blood loss was 385-520 mL (mean, 446.2 mL), and the fluoroscopy frequency was 18-34 times (mean, 27.5 times). Postoperative fat liquefaction occurred in 1 case and the other incisions healed by first intention; 3 cases had limb numbness after operation, and the symptoms disappeared after active symptomatic treatment; no urogenital system and intestinal injury occurred. All patients were followed up 12-28 months (mean, 19.9 months). Bone union was achieved in all cases with an average healing time of 10.8 weeks (range, 8-14 weeks). There was no complication such as loosening and breakage of internal fixators. At last follow-up, according to Matta score, 12 cases achieved anatomic reduction, 3 satisfactory reduction, and 2 fair reduction, the satisfactory rate was 88.2%; according to Harris hip function score, 12 cases were excellent, 3 good, and 2 fair, the excellent and good rate was 88.2%; according to the modified Merle D'Aubign Aubigné-Postel scoring system, the results were excellent in 11 cases, good in 3 cases, and fair in 3 cases, with an excellent and good rate of 82.4%.@*CONCLUSION@#The single Kocher-Langenbeck approach combined with anterograde channel screw technique is a minimally invasive method for the treatment of acetabular transverse and posterior wall fractures with less complications, simple operation, and satisfactory effectiveness.

ABSTRACT

OBJECTIVE@#To compare the effectiveness of O-arm navigation and C-arm navigation for guiding percutaneous long sacroiliac screws in treatment of Denis type Ⅱ sacral fractures.@*METHODS@#A retrospective study was conducted on clinical data of the 46 patients with Denis type Ⅱ sacral fractures between April 2021 and October 2022. Among them, 19 patients underwent O-arm navigation assisted percutaneous long sacroiliac screw fixation (O-arm navigation group), and 27 patients underwent C-arm navigation assisted percutaneous long sacroiliac screw fixation (C-arm navigation group). There was no significant difference in gender, age, causes of injuries, Tile classification of pelvic fractures, combined injury, the interval from injury to operation between the two groups ( P>0.05). The intraoperative preparation time, the placement time of each screw, the fluoroscopy time of each screw during placement, screw position accuracy, the quality of fracture reduction, and fracture healing time were recorded and compared, postoperative complications were observed. Pelvic function was evaluated by Majeed score at last follow-up.@*RESULTS@#All operations were completed successfully, and all incisions healed by first intention. Compared to the C-arm navigation group, the O-arm navigation group had shorter intraoperative preparation time, placement time of each screw, and fluoroscopy time, with significant differences ( P<0.05). There was no significant difference in screw position accuracy and the quality of fracture reduction ( P>0.05). There was no nerve or vascular injury during screw placed in the two groups. All patients in both groups were followed up, with the follow-up time of 6-21 months (mean, 12.0 months). Imaging re-examination showed that both groups achieved bony healing, and there was no significant difference in fracture healing time between the two groups ( P>0.05). During follow-up, there was no postoperative complications, such as screw loosening and breaking or loss of fracture reduction. At last follow-up, there was no significant difference in pelvic function between the two groups ( P>0.05).@*CONCLUSION@#Compared with the C-arm navigation, the O-arm navigation assisted percutaneous long sacroiliac screws for the treatment of Denis typeⅡsacral fractures can significantly shorten the intraoperative preparation time, screw placement time, and fluoroscopy time, improve the accuracy of screw placement, and obtain clearer navigation images.

ABSTRACT

Objetivos: Comunicar los resultados funcionales y radiográficos en seis pacientes con fractura "en pico de pato" (beak fracture)y realizar una revisión de la bibliografía.materiales y métodos:Se evaluaron los resultados funcionales (escala de la AOFAS) y radiológicos en seis pacientes (3 hombres y 3 mujeres; edad promedio 35.6 años). El tiempo promedio transcurrido entre la lesión y el ingreso en el quirófano fue de 2.83 h. Se realizó la rama vertical del abordaje lateral extendido. Se fijó con tornillos canulados y macizos de 3,5; 4,0 o 4,5 mm solos o combinados con placas de 3,5 y 2,7 mm bloqueadas.Resultados:Después de un seguimiento de entre 8 y 24 meses, todos los pacientes tenían signos francos de consolidación. Al ingresar, todos presentaban signos de sufrimiento de partes blandas sin signos de necrosis. El puntaje de la escala de la AOFAS fue de 82,4 (5, buenos y 1, regular). Las complicaciones fueron: una infección profunda y pérdida de la reducción en el mismo paciente.Conclusiones:Las fracturas "en pico de pato" pueden generar complicaciones de partes blandas si no son tratadas de manera urgente, debido al compromiso inicial de partes blandas. La reducción abierta y la fijación con tornillos y placas es el sistema de fijación más estable. Nivel de Evidencia: IV


Objectives: To present the functional and radiographic outcomes of six patients with beak fractures and to carry out a literature review. materials and methods: The functional (AOFAS Score) and radiological outcomes of six patients were evaluated. Three patients were male and three were female (mean age: 35.6 years). The mean time interval between injury and admission to the operating room was 2.83 hours. The extensile lateral approach was used. The fracture was fixed with 3.5, 4.0, or 4.5mm cannulated and solid screws alone or in combination with 3.5 and 2.7mm locking plates. Results: After a follow-up period of between 8 and 24 months, all the patients had clear signs of consolidation. On admission, all presented signs of soft tissue pain without signs of necrosis. The AOFAS score was 82.4 (5 good and 1 fair). The complications observed were a deep infection and loss of reduction in the same patient. Conclusions: Beak fractures can generate soft tissue complications if they are not treated urgently due to initial soft tissue involvement. Open reduction and fixation with screws and plates is the most stable fixation system. Level of Evidence: IV

ABSTRACT

Introducción: La fractura de Maisonneuve es una lesión caracterizada por la fractura subcapital del peroné asociada a una lesión capsuloligamentaria de tobillo. Su tratamiento supone la restauración de la anatomía ósea y capsuloligamentaria normal para restablecer las fuerzas de contacto tibioastragalinas fisiológicas. Esta calidad de reducción puede ser difícil de alcanzar, sobre todo, con técnicas percutáneas. Objetivo: Evaluar mediante imágenes la calidad de la reducción de fracturas de Maisonneuve reducidas en forma cerrada (bajo visualización directa artroscópica) y fijadas por vía percutánea. Materiales y Métodos: Se analizaron radiografías e imágenes de tomografía computarizada preoperatorias y posoperatorias, comparativas de los tobillos operado y sano. Resultados: Se evaluaron 13 fracturas. Los parámetros radiográficos posoperatorios (espacio claro medial, solapamiento tibioperoneo distal, espacio claro tibioperoneo) no registraron diferencias, excepto por el intervalo tibioperoneo anterior que aumentó en un caso. La medición tomográfica posoperatoria del solapamiento tibioperoneo distal y el intervalo tibioperoneo anterior reveló que todas las reducciones eran satisfactorias. Dos pacientes tenían valores alterados en la sindesmosis tibioperonea distal con diferencia >2 mm respecto del tobillo sano. Conclusión: Recomendamos la asistencia artroscópica para el manejo de la fractura de Maisonneuve como herramienta de control intraoperatorio para una fijación percutánea más segura. Nivel de Evidencia: IV


Introduction: Maisonneuve fracture (MF) is an injury characterized by the subcapital fracture of the fibula associated with a capsuloligamentous injury of the ankle. Treatment involves the restoration of normal bone and capsuloligamentous anatomy in order to reestablish physiological tibiotalar contact forces. This quality of reduction can be difficult to achieve, especially with percutaneous techniques. Objective: To evaluate the quality of reduction in Maisonneuve fractures reduced in a closed manner (under direct arthroscopic visualization) and fixed percutaneously. Materials and Methods: We analyzed comparative preoperative and postoperative radiographs and CT scans of the operated and healthy ankles. Results: 13 fractures were evaluated. Radiographic parameters of postoperative procedures (medial clear space, distal tibiofibular overlap, tibiofibular clear space) did not register differences except for the anterior tibiofibular space, which had increased in 1 case. Postoperative tomographic measurements of tibiofibular clear space and anterior tibiofibular space showed 100% satisfactory reductions. Two patients presented altered distal tibiofibular overlap values with a difference greater than 2 mm compared to the healthy ankle. Conclusion: We recommend arthroscopy for the management of MF as an intraoperative control tool for safer percutaneous fixation. Level of Evidence: IV

ABSTRACT

Introducción: Las luxofracturas vertebrales toracolumbares se producen por traumatismos de alta energía, representan el 10% de las lesiones traumáticas de la columna vertebral y se asocian frecuentemente con otras lesiones. El objetivo de este estudio fue comparar las complicaciones tempranas en pacientes con una luxofractura toracolumbar según la oportunidad quirúrgica, antes o después de las 24 h del trauma. Materiales y métodos: Estudio multicéntrico, analítico, observacional y retrospectivo de una cohorte de pacientes operados por una luxofractura toracolumbar, desde el 1 de enero de 2014 hasta el 1 de enero de 2023. Se inclu-yó a pacientes de ambos sexos, >18 años, operados por una luxofractura vertebral de alta energía. Se los agrupó según si habían sido operados de columna antes o después de las 24 h del trauma. Se registraron las complicaciones totales y agrupadas. Resultados: Se evaluó a 72 pacientes, 64 hombres (88,9%) y 8 mujeres (11,1%), con una edad promedio de 35.94 años. Predominaron las instituciones laborales (n = 60; 83,3%). El mecanismo de lesión más frecuente fueron los accidentes de tránsito (n = 42; 58,3%), seguidos de las caídas de altura (n = 26; 36,1%). El 86% sufrió una o más lesiones asociadas. Se registraron 283 complicaciones en 67 (93,1%) pacientes y 45 complicaciones quirúrgicas en 26 pacientes (36,1%). La mediana de complicaciones fue mayor en pacientes operados tardíamente (p = 0,004). Conclusiones:Los pacientes con luxofractura toracolumbar operados después de las primeras 24 h presentaron una mediana de complicaciones totales significativamente mayor que los operados precozmente.

Introduction: Thoracolumbar fracture-dislocations account for 10% of traumatic spinal injuries and typically occur in the context of high-energy trauma. Our objective is to compare early complications in patients with thoracolumbar fracture-dislocation based on surgical timing, either before or after 24 hours from the trauma.materials and methods: This is a multicenter, retrospective cohort study of patients surgically treated for thoracolumbar dislocations, from January 1, 2014 to January 1, 2023. We included adult patients (>18 years old) of any gender, surgically treated for high-energy thoracolumbar fracture-dislocations. Patients were grouped based on when they underwent spinal surgery: before or after 24 hours following trauma. Total and grouped complications were recorded. Results: Our sample comprised 72 patients, with 64 men (88.9%) and 8 women (11.1%) at an average age of 35.94 years. Occupational health care centers were predominant (n=60; 83.3%). Road traffic accidents (n=42; 58.3%) were the most frequent cause of injury, followed by falls from height (n=26; 36.1%). Furthermore, 86% of patients had one or more associated injuries. In total, 283 complications were recorded, with 67 patients (93.1%) suffering at least one complication, and 26 patients (36.1%) experiencing surgical complications. The median number of complications was significantly higher in late-operated patients (p=0.004). Conclusions: Patients with thoracolumbar dislocations who underwent surgery after the first 24 hours following trauma had a significantly higher median rate of complications than those who underwent early surgery.

ABSTRACT

Objetivo: Presentar una serie de casos de pacientes con fracturas cervicales de tipo "masa lateral flotante" con énfasis en describir el rol de la lesión discal en la potencial inestabilidad segmentaria. Materiales y métodos: Se realizó un estudio descriptivo y retrospectivo de una serie de pacientes con fracturas facetarias de tipo "masa lateral flotante", aisladas, diagnosticadas entre el 1 de enero de 2016 y el 1 de enero de 2022. Se incluyeron pacientes con lesiones de tipo "masa lateral flotante" según la clasificación AO, diagnosticadas por tomografía computarizada y, al menos, 6 meses de seguimiento. Se excluyó a aquellos con fracturas patológicas, lesiones por fragilidad ósea y registros incompletos. Resultados: Se analizó a 16 pacientes (media de la edad 42.86; DE 12,396), con predominio del sexo masculino (81,25%). El 68,75% tenía una lesión del disco intervertebral en el segmento fracturado y el 18,75%, anterolistesis. A 11 pacientes se les propuso un tratamiento conservador durante 12 semanas. La fractura consolidó en el 45,4% y 6 (54,6%) evolucionaron con traslación. El fracaso del tratamiento conservador se asoció con lesión del disco intervertebral. Once pacientes fueron operados, en su mayoría, con artrodesis cervical anterior monosegmentaria. Conclusiones: En esta serie de casos, la presencia de una lesión asociada del disco intervertebral fue más frecuente cuando el tratamiento conservador fracasó y cuando se decidió una artrodesis como tratamiento inicial. La mayoría de las cirugías se realizaron por vía anterior con discectomía y artrodesis cervical anterior en un único nivel, y se lograron buenos resultados. Nivel de Evidencia: IV


Introduction: We report a series of patients with "floating lateral mass" cervical fractures, focusing on the role of disc injury in potential segmental instability. materials and methods: We conducted a descriptive and retrospective study on a case series of isolated floating lateral mass facet fractures diagnosed between January 1, 2016 and January 1, 2022. Patients with floating lateral mass lesions according to the AO classification, diagnosed by computed tomography, and at least 6 months of follow-up were included. Patients with pathological fractures, bone fragility injuries and incomplete records were excluded. Results: We included 16 cases, the average age was 42.86 (SD 12.396), and the majority were male (n=13; 81.25%). 68.75% (n=11) had intervertebral disc injury in the fractured segment, while 18.75% (n=3) had anterolisthesis. Conservative treatment was proposed for 12 weeks in 11 patients (68.75%), of whom 5 (45.4%) achieved fracture healing and 6 (54.6%) progressed to translation. Cases where conservative treatment failed were associated with intervertebral disc injury. Eleven patients were treated surgically, mostly with monosegmental anterior cervical arthrodesis. Conclusions: We report a series of cases in which the existence of an associated intervertebral disc injury was more frequent in patients with failed conservative treatment and in those initially treated with arthrodesis. Most of the surgical cases were treated using an anterior approach with discectomy and anterior cervical arthrodesis at a single level, with favorable outcomes. Level of Evidence: IV

ABSTRACT

RESUMEN Introducción: Los tratamientos para fracturas de órbita se basan en la corrección del defecto de las lesiones orbitarias de tipo blow in y blow out (o de estallido), mediante diversas placas y mallas biocompatibles con el organismo, dándose una cicatrización de primera generación evitando un callo óseo y una fijación más rígida. Para el diagnóstico de este tipo de lesiones tenemos inflamación periorbitaria, enoftalmos, diplopía, equimosis, hemorragia subconjuntival. Existen diversos materiales reconstructivos siendo estos compuestos por distintas materias primas, como son los aloplásticos y autógenos; donde encontramos varios tipos como placas de titanio y las placas reabsorbibles siendo estas las más comunes y usadas actualmente, por su bajo estímulo a reabsorciones óseas y evitando efectos secundarios a largo plazo. Estas placas presentan diversos grados de ductilidad y resistencia. Se informó sobre varias complicaciones según el tipo de placas como es la cicatrización, las cirugías postquirúrgicas en caso de placas de titanio, etc. El objetivo de esta revisión es la evaluación de la eficacia las placas reabsorbibles versus placas de titanio en fracturas de órbita. Materiales y métodos: La investigación es de carácter documental, descriptivo y no experimental. En el cual se emplea una metodología de identificación e inclusión de artículos científicos tipo prisma. Resultados y conclusiones: Se verificaron las ventajas y desventajas tanto de las placas reabsorbibles como las de titanio siendo estas similares en la biocompatibilidad con el organismo humano, así como también varias diferencias como el soporte, fuerzas, resistencia de estas, concluyendo que es debatible el material ideal para tratar fracturas de órbita. Se seleccionaron artículos tomando en cuenta el título y objetivos; considerando estudios comparativos, revisiones sistemáticas, revisiones de literatura, los cuales comprendían criterios con respecto a fracturas de órbita y tratamientos quirúrgicos. La búsqueda arrojó 55 artículos en PubMed, 65 en Google, 4 en Scielo y 29 en Science direct, de los cuales se excluyeron libros, monografías, estudios experimentales, dando como resultado 21 artículos para el desarrollo de esta revisión bibliográfica. Y que fueron leídos y analizados en su totalidad, estudiando los objetivos, metodología y conclusión de cada uno de ellos para la posterior comparación.


ABSTRACT Introduction: Treatments for orbit fractures are based on the correction of the defect of blow in and blow out orbital injuries, by means of various plates and meshes biocompatible with the organism, giving a first-generation healing avoiding a bony callus and a more rigid fixation. For the diagnosis of this type of lesions we have periorbital inflammation, enophthalmos, diplopia, ecchymosis, subconjunctival hemorrhage. There are several reconstructive materials being these composed of different raw materials, such as alloplastic and autogenous, where we find several types such as titanium plates and resorbable plates being these the most common and currently used, for its low stimulus to bone resorption and avoiding long-term side effects. These plates have different degrees of ductility and resistance. Several complications have been reported depending on the type of plates, such as scarring, post-surgical surgeries in the case of titanium plates, etc. The objective of this review is to evaluate the efficacy of resorbable versus titanium plates in orbital fractures. Materials and methods: This research are a documentary, descriptive and non-experimental nature. A prism-type methodology of identification and inclusion of scientific articles was used. Results and conclusions: The advantages and disadvantages of both resorbable and titanium plates were verified, being these similar in biocompatibility with the human organism, as well as several differences such as support, forces, resistance of the same, concluding that it is debatable. The ideal material to treat orbital fractures. Articles were selected considering the title and objectives; considering comparative studies, systematic reviews, literature reviews, which included criteria regarding orbital fractures and surgical treatments. The search yielded 55 articles in PubMed, 65 in Google, 4 in Scielo and 29 in Science direct, from which books, monographs, experimental studies were excluded, resulting in 21 articles for the development of this bibliographic review. The 21 articles were read and analyzed in their entirety, studying the objectives, methodology and conclusion of each one of them for subsequent comparison.

ABSTRACT

Objetivo: sintetizar as principais evidências acerca das alterações osteometabólicas presentes nos pacientes em tratamento antineoplásico. Métodos: trata-se de uma revisão de escopo, seguindo a metodologia do Instituto Joanna Briggs, nas bases de dados PubMed/MedLine, Cochrane Library, LILACS, The British Library e Google Scholar. A revisão está protocolada no Open Science Framework. Resultados: muitos antineoplásicos possuem efeito na arquitetura óssea, reduzindo sua densidade, tais como moduladores seletivos de receptores de estrogênio, inibidores da aromatase, terapia de privação androgênica, e glicocorticoides. Para evitar tais desfechos, o tratamento e prevenção podem ser realizados pela suplementação de cálcio e vitamina D, exercícios físicos, uso de bifosfonatos, denosumab, e moduladores seletivos do receptor de estrogênio. Conclusão: pessoas com maior risco de desenvolver câncer também possuem maior risco de osteopenia e osteoporose, quando processo já estabelecido e em tratamento antineoplásico, devido ao compartilhamento de fatores de risco. Torna-se evidente a necessidade da densitometria óssea nos pacientes em tratamento contra o câncer para de prevenção e promoção de saúde óssea nesses pacientes, além de mais pesquisas com alto nivel de evidência para subsidiar tal uso.


Objective: To summarize the main evidence regarding osteometabolic changes in patients undergoing antineoplastic treatment. Methods: This is a scoping review, following the methodology of the Joanna Briggs Institute, using PubMed/MedLine, Cochrane Library, LILACS, The British Library, and Google Scholar. This review is registered in the Open Science Framework. Results: Many antineoplastics affect bone architecture by reducing its density, such as selective estrogen receptor modulators, aromatase inhibitors, androgen deprivation therapy, and glucocorticoids. To avoid such outcomes, treatment and prevention can be achieved by calcium and vitamin D supplementation, physical exercise, use of bisphosphonates, denosumab, and selective estrogen receptor modulators. Conclusion: people at a higher risk of developing cancer also have a higher risk of osteopenia and osteoporosis when the process is already established and undergoing antineoplastic treatment because of the grouping of risk factors. The need for bone densitometry in patients undergoing cancer treatment to prevent and promote bone health in these patients is evident, in addition to more research with a high level of evidence to support such use.

ABSTRACT

Abstract Historically, surgeries on the immature skeleton were reserved for open or articular fractures. In recent years, the improvement in the quality and safety of anesthesia, new imaging equipment, implants designed especially for pediatric fractures, associated with the possibility of shorter hospitalization time and rapid return to social life has demonstrated a new tendency to evaluate and treat fractures in children. The purpose of this update article is to answer the following questions: (1) Are we really turning more surgical in addressing fractures in children? (2) If this is true, is this surgical conduct based on scientific evidence? In fact, in recent decades, the medical literature demonstrates articles that support better evolution of fractures in children with surgical treatment. In the upper limbs, this is very evident in the systematization of the reduction and percutaneous fixation of supracondylar fractures of the humerus and fractures of the forearm bones. In the lower limbs, the same occurs with diaphyseal fractures of the femur and tibia. However, there are gaps in the literature. The available published studies show low scientific evidence. Thus, it can be inferred that, even though the surgical approach is more present, the treatment of pediatric fractures should always be individualized and conducted according to the knowledge and experience of the professional physician, taking into account the presence of technological resources available for the care of the small patient. All possibilities, non-surgical and/or surgical, should be included, always instituting actions based on science and in agreement with the family's wishes.


Resumo Historicamente, as cirurgias no esqueleto imaturo eram reservadas às fraturas expostas ou articulares. Nos últimos anos, a melhora na qualidade e segurança das anestesias, novos equipamentos de imagem, implantes desenhados especialmente para fraturas pediátricas, associados à possibilidade de menor tempo de hospitalização e rápido retorno ao convívio social vêm demonstrando uma nova tendência de avaliar e tratar fraturas na criança. O objetivo deste artigo de atualização é responder às seguintes questões: (1) estamos realmente ficando mais cirúrgicos na abordagem das fraturas em crianças? (2) Caso isto seja verdadeiro, esta conduta cirúrgica está baseada em evidências científicas? De fato, nas últimas décadas, a literatura médica demonstra artigos que suportam melhor evolução das fraturas na criança com o tratamento cirúrgico. Nos membros superiores, isto fica muito evidente na sistematização da redução e fixação percutânea das fraturas supracondilianas do úmero e das fraturas de ossos do antebraço. Nos membros inferiores, o mesmo ocorre com fraturas diafisárias do fêmur e tíbia. No entanto, há lacunas na literatura. Os estudos publicados são geralmente com baixa evidência científica. Assim, pode-se deduzir que, mesmo sendo a abordagem cirúrgica mais presente, o tratamento de fraturas pediátricas deve ser sempre individualizado e conduzido de acordo com o conhecimento e experiência do médico profissional, levando em conta a presença de recursos tecnológicos disponíveis para o atendimento do pequeno paciente. Deve-se incluir todas as possibilidades, não cirúrgicas e/ou cirúrgicas, sempre instituindo ações baseadas na ciência e em concordância com os anseios da família.

ABSTRACT

Abstract Objective This study assessed differences between fully- and partially-threaded screws in the initial interfragmentary compression strength. Our hypothesis was that there would be an increased loss in initial compression strength with the partially-threaded screw. Methods A 45-degree oblique fracture line was created in artificial bone samples. The first group (FULL, n = 6) was fixed using a 3.5-mm fully-threaded lag screw, while the second group (PARTIAL, n = 6) used a 3.5-mm partially-threaded lag screw. Torsional stiffness for both rotational directions were evaluated. The groups were compared based on biomechanical parameters: angle-moment-stiffness, time-moment-stiffness, maximal torsional moment (failure load), and calibrated compression force based on pressure sensor measurement. Results After loss of one PARTIAL sample, no statistically significant differences in calibrated compression force measurement were observed between both groups: [median (interquartile range)] FULL: 112.6 (10.5) N versus PARTIAL: 106.9 (7.1) N, Mann-Whitney U-test: p = 0.8). In addition, after exclusion of 3 samples for mechanical testing (FULL n = 5, PARTIAL n = 4), no statistically significant differences were observed between FULL and PARTIAL constructs in angle-moment-stiffness, time-moment-stiffness, nor maximum torsional moment (failure load). Conclusion There is no apparent difference in the initial compression strength (compression force or construct stiffness or failure load) achieved using either fully-or partially-threaded screws in this biomechanical model in high-density artificial bone. Fully-threaded screws could, therefore, be more useful in diaphyseal fracture treatment. Further research on the impact in softer osteoporotic, or metaphyseal bone models, and to evaluate the clinical significance is required.


Resumo Objetivo Este estudo avaliou diferenças entre parafusos com rosca total ou parcial na resistência à compressão interfragmentar inicial. Nossa hipótese era de que haveria maior perda de resistência à compressão inicial com o parafuso de rosca parcial. Métodos Uma linha de fratura oblíqua de 45 graus foi criada em amostras de osso artificial. O primeiro grupo (TOTAL, n = 6) foi fixado com um parafuso de 3,5 mm de rosca total, enquanto o segundo grupo (PARCIAL, n = 6) usou um parafuso de 3,5 mm de rosca parcial. Avaliamos a rigidez à torção em ambas as direções de rotação. Os grupos foram comparados com base nos seguintes parâmetros biomecânicos: momento de rigidez-ângulo, momento de rigidez-tempo, momento de torção máxima (carga de falha) e força de compressão calibrada com base na medida do sensor de pressão. Resultados Depois da perda de uma amostra PARCIAL, não foram observadas diferenças estatisticamente significativas na força de compressão calibrada entre os 2 grupos [mediana (intervalo interquartil)]: TOTAL: 112,6 (10,5) N e PARCIAL: 106,9 (7,1) N, com p = 0,8 segundo o teste U de Mann-Whitney). Além disso, após a exclusão de 3 amostras para testes mecânicos (TOTAL, n = 5, PARCIAL, n = 4), não foram observadas diferenças estatisticamente significativas entre os construtos TOTAL e PARCIAL quanto ao momento de rigidez-ângulo, momento de rigidez-tempo ou momento de torção máxima (carga de falha). Conclusão Não há diferença aparente na força de compressão inicial (força de compressão ou rigidez do construto ou carga de falha) com o uso de parafusos de rosca total ou parcial neste modelo biomecânico em osso artificial de alta densidade. Parafusos de rosca total podem, portanto, ser mais úteis no tratamento de fraturas diafisárias. Mais pesquisas são necessárias sobre o impacto em modelos ósseos osteoporóticos ou metafisários de menor densidade e avaliação do significado clínico.

ABSTRACT

Introducción: Los traumatismos constituyen causa frecuente de consulta. Entre sus localizaciones más comunes se encuentran las extremidades inferiores. El Heberprot-P® resulta un factor de crecimiento epidérmico que se ha utilizado durante más de una década para la cicatrización de las úlceras del pie diabético con excelentes resultados. Ampliar su utilización a otras patologías, incluso de etiología traumática, permitiría expandir las posibilidades terapéuticas para la cicatrización de las heridas. Objetivo: Exponer el resultado de la aplicación del Heberprot-P® en una amputación transtarsiana en un paciente portador de un trauma vascular distal. Presentación del caso: Paciente masculino de 23 años con antecedentes de salud. Luego de traumatismo por accidente de tránsito presentó fractura de huesos del metatarso y la sección total de la arteria pedia del pie izquierdo, lo cual provocó una gangrena húmeda de la extremidad. Por este motivo se realizó una amputación transtarsiana del pie. Se usó el Heberprot-P® como terapia para acortar el tiempo de cicatrización. Conclusiones: El Heberprot-P® resultó útil para la evolución de la herida como consecuencia de un trauma vascular, al evitar una amputación mayor, acelerar el proceso de cicatrización y conservar una extremidad funcional, lo que demostró que puede constituir una terapia eficaz para las heridas de difícil cicatrización, independientemente de su etiología(AU)


Introduction: Trauma is a frequent cause of consultation. Among its most common locations are the lower extremities. Heberprot-P® is an epidermal growth factor that has been used for more than a decade for the healing of diabetic foot ulcers with excellent results. Extending its use to other pathologies, including traumatic etiology ones, would expand the therapeutic possibilities for wound healing. Objective: To present the result of the application of Heberprot-P® in a Chopart´s amputation in a patient with distal vascular trauma. Case presentation: A 23-year-old male patient with a health history. After trauma from a traffic accident, he presented a fracture of the bones of the metatarsus and the whole section of the left foot´s pedis artery, which caused a wet gangrene of the extremity. For this reason, a Chopart´s amputation of the foot was performed. Heberprot-P® was used as therapy to shorten healing time. Conclusions: Heberprot-P® was useful for wound evolution as a result of vascular trauma, avoiding major amputation, accelerating the healing process and preserving a functional limb, which showed that it can be an effective therapy for wounds that are difficult to heal, regardless of their etiology(AU)

ABSTRACT

Introducción: Las fracturas de escápula tienen una baja frecuencia, se presentan mayoritariamente en población joven tras traumatismos de alta energía. Su tratamiento historicamente ha sido conservador, sin embargo, el tratamiento quirúrgico ha demostrado mejores resultados funcionales en pacientes seleccionados, siendo la indicación quirúrgica aún controversial. La literatura sobre los pacientes tratados de forma quirúrgica es escasa. Objetico general: Caracterizar a los pacientes operados por fractura de escapula en Hospital Traumatológico de Concepción durante los años 2019-2022. Materiales y métodos: Estudio descriptivo que incluye a pacientes operados por fractura de escápula en el Hospital Traumatológico de Concepción durante los años 2019 al 2022, considerando las variables sexo, edad, lateralidad, mecanismo de lesión y lesiones asociadas. Resultados: Se estudiaron 20 pacientes de los cuales 90% fueron hombres, registrándose un promedio de edad de 41 años, sin diferencias significativas en su lateralidad. Los principales mecanismos de lesión fueron accidentes de tránsito y caídas de altura, existiendo lesiones asociadas sólo en 45% de los casos. Conclusión: Las fracturas de escápula tienen alto impacto en la funcionalidad de la extremidad afectada, por lo que su tratamiento hoy en día esta evolucionando hacia uno quirúrgico en pacientes seleccionados, con el fin de obtener mejores resultados funcionales. Los pacientes operados son mayoritariamente adultos de edad media de sexo masculino, con fracturas secundarias a traumatismos de alta energía y presencia de lesiones asociadas de baja morbimortalidad.


Introduction: Scapula fractures have a low frequency. They occur mainly in the young population after high-energy trauma. Its treatment has historically been conservative; however, surgical treatment has shown better functional results in selected patients, the surgical indication being still controversial. The literature on patients treated surgically is scarce. General Objective: Characterize the patients operated on for scapular fracture at the Hospital Traumatológico de Concepción during the years 2019-2022. Materials and methods: Descriptive study that includes patients operated on for scapula fracture at the Concepción Trauma Hospital during the years 2019 to 2022, considering the variables sex, age, laterality, mechanism of injury and associated injuries. Results: Twenty patients were studied, of whom 90% were men, recording an average age of 41 years, with right scapula fracture being slightly more frequent than left. The main mechanisms of injury were traffic accidents and falls from a height, with associated injuries only in 45% of the cases. Conclusion: Scapula fractures have a high impact on the functionality of the affected limb, so their treatment today is evolving towards surgery in selected patients, in order to obtain better functional results. The patients operated on are mostly middle-aged male adults, with fractures secondary to high-energy trauma and the presence of associated lesions with low morbidity and mortality.

ABSTRACT

Abstract Objective Various modalities have been suggested to manage mallet fractures; however, inappropriate treatment can lead to extension lag, a swan neck deformity, or arthritis of the distal interphalangeal joint (DIPJ). The current study aimed to evaluate the results (functional, radiological, and complications) of open reduction and internal fixation (ORIF) of mallet fractures using low-cost hook plates fabricated from low-profile titanium mini plates. Methods A prospective case series of 17 consecutive patients (average age of 32.3 years) with mallet fractures (six were Wehbe Type IB and 11 were Wehbe Type MB). Eleven (64.7%) were males. The affected hand was dominant in all patients, and the affected digit was the index in 6 (35.3%), the ring in 5 (29.4%), the small in 3 (17.65%), and the middle in 3 (17.65%) patients. The same fellowship-trained hand surgeon performed all surgeries. Results The average operative time was 37.65 minutes. After an average follow-up of 10.94 months (range 6-27), the average DIPJ motion was 50º º (range 20º-70º), the extensor lag was noted in 4 (23.5%) patients, and complications were reported in 6 (35.29%) patients. According to Crawford criteria, 6 (35.3%) patients achieved excellent results, 7 (41.2%) achieved good results, and 4 (23.5%) achieved fair results. Conclusion The modified hook plate technique for fixation of mallet fractures is a beneficiai, economical, yet demanding technique that adequately provides stable fixation to allow early DIPJ motion with acceptable functional outcomes.


Resumo Objetivo Diversas modalidades têm sido sugeridas para o tratamento de fraturas em martelo; no entanto, o tratamento inadequado pode causar retardo de extensão, deformidade em pescoço de cisne ou artrite da articulação interfalangiana distal (AIFD). Este estudo teve como objetivo avaliar os desfechos (funcionais, radiológicos e complicações) da redução aberta e fixação interna (RAFI) das fraturas em martelo com placas de gancho de baixo custo fabricadas com mini placas de titânio de baixo perfil. Métodos Série de casos prospectivos de 17 pacientes consecutivos (idade média de 32,3 anos) com fraturas em martelo (seis do tipo IB e 11 do tipo IIB de Wehbe). Onze (64,7%) pacientes eram do sexo masculino. A mão acometida era a dominante em todos os pacientes, com acometimento do dedo indicador em seis (35,3%), anelar em cinco (29,4%), mínimo em três (17,65%) e médio em três (17,65%) pacientes. O mesmo cirurgião de mão experiente realizou todas as cirurgias. Resultados O tempo operatório médio foi de 37,65 minutos. Após um acompanhamento médio de 10,94 meses (intervalo de 6 a 27), observou-se movimento médio da AIFD de 50º (intervalo de 20º a 70º), retardo de extensão em quatro (23,5%) pacientes e complicações em seis (35,29%) pacientes. De acordo com os critérios de Crawford, os desfechos foram excelentes em seis (35,3%), bons em sete (41,2%) e regulares em quatro (23,5%) pacientes. Conclusão A técnica da placa de gancho modificada para fixação de fraturas em martelo é benéfica e econômica, mas exigente; permite fixação estável e adequada para permitir a movimentação precoce da AIFD com desfechos funcionais aceitáveis.
