Use of Three-dimensional Printing for Tibial Pilon Fracture Diagnosis and Treatment / Uso da impressão tridimensional para auxílio diagnóstico e terapêutico das fraturas de pilão tibial

Abstract Objective To evaluate whether three-dimensional (3D) printing increases agreement in the classification of tibial pilon fractures. Methods Orthopedists and traumatologists reviewed radiographs, computed tomography scans with 3D reconstruction, and prototyping 3D printing, and classified the fractures based on the Rüedi-Allgöwer and Arbeitsgemeinschaft für Osteosynthesefragen (AO, Association for the Study of Internal Fixation) Foundation/Orthopedic Trauma Association (AO/OTA) classification systems. Next, data evaluation used Kappa agreement coefficients. Results The use of the 3D model did not improve agreement for tibial pilon fractures regarding the treatment proposed by the groups. Regarding the classification systems, the agreement only improved concerning the AO/OTA classification when the 3D model was used in the assessment by the foot and ankle specialists. Conclusion Although 3D printing is statistically relevant for surgeons specializing in foot and ankle, its values remain lower than optimal.

Resumo Objetivo Avaliar se a impressão tridimensional (3D) aumenta a concordância na classificação de fraturas do pilão tibial. Métodos Foram selecionadas radiografias, tomografias com reconstrução 3D e impressão de prototipagem em impressora 3D. Os exames foram apresentados a profissionais da área de Ortopedia e Traumatologia que classificaram as fraturas com base nas classificações da Arbeitsgemeinschaft für Osteosynthesefragen (AO, Associação para o Estudo da Fixação Interna) Foundation/Orthopedic Trauma Association (AO/OTA) e de Rüedi-Allgöwer. Posteriormente, os dados foram avaliados pelos coeficientes de concordância de Kappa. Resultados O uso do modelo 3D não melhorou a concordância na fratura do pilão tibial quanto ao tratamento proposto pelos grupos. Em relação aos sistemas de classificação, somente a concordância na classificação AO/OTA melhorou quando foi utilizado o modelo 3D na avaliação pelos especialistas em pé e tornozelo. Conclusão Apesar de o uso da impressão 3D ter relevância estatística para os cirurgiões especialistas em pé e tornozelo, ainda apresenta valores menores do que os ideais.

Early Intraprosthetic Dislocation of Total Hip Arthroplasty with Double Mobility Implant: Case Report / Luxação intraprotética precoce de artroplastia total do quadril com implante de dupla mobilidade: Relato de caso

Abstract Total hip arthroplasty (THA) is a successful surgery in the treatment of hip pain, but there are potential complications, of which dislocation is one of the most common. Dislocation management is a challenging problem that requires a multimodal approach, and the use of dual mobility implants is an option. We present a patient with a history of femoral neck fracture who underwent THA with a double mobility implant. On the 18th postoperative day, after a fall to the ground, she developed prosthesis dislocation and had a complication after closed reduction, a subsequent intraprosthetic dislocation. After a radiographic diagnosis, the patient presented mechanical signs of hip flexion caused by a disassociated double mobility implant. The revision surgery was indicated, but the patient chose not to perform the necessary surgical procedure. A careful postoperative study of the radiographs revealed an eccentric femoral head and evidence of disassociated implantation in the surrounding soft tissues. Radiographs after closed reduction of intraprosthetic dislocations should be examined thoroughly.

Resumo A artroplastia total do quadril (ATQ) é uma cirurgia bem-sucedida no tratamento da dor no quadril, mas existem complicações potenciais, das quais a luxação é uma das mais comuns. O gerenciamento das luxações é um problema desafiador que requer uma abordagem multimodal, e o uso de implantes de mobilidade dupla é uma opção. Apresentamos uma paciente com história de fratura do colo do fêmur que foi submetida a ATQ com um implante de dupla mobilidade. No 18° dia pós-operatório, após queda ao solo, a paciente evoluiu com luxação da prótese e teve uma complicação após redução fechada, uma luxação intraprotética subsequente. Após um diagnóstico radiográfico, a paciente apresentou sinais mecânicos na flexão do quadril causados por um implante de mobilidade dupla desassociado. A cirurgia de revisão foi indicada, mas a paciente optou por não realizar o procedimento cirúrgico necessário. O estudo pós-operatório cuidadoso das radiografias revelou uma cabeça femoral excêntrica e evidências do implante desassociado nos tecidos moles circundantes. As radiografias após a redução fechada das luxações intraprotéticas devem ser examinadas minunciosamente.

Treatment of Two-column Acetabular Fractures by Double Extrapelvic Approach: Three Clinical Cases / Tratamento de fraturas acetabulares de duas colunas por dupla via extrapélvica: Três casos clínicos

Abstract Fractures of two columns of the acetabulum according to the Letournel classification are among the most common in frequency, indication and surgical complexity. These are mainly the result of lateral compression mechanisms and are characterized by originating a disconnected acetabulum from the axial skeleton. Its surgical treatment may include: isolated anterior or posterior approach; combined, at the same surgical time or not; or broad approaches. The authors present another surgical option with association of the Kocher-Langenbeck pathway with the iliac crest approach simultaneously and in the same positioning (lateral decubitus) based on the first three clinical cases performed and their clinical and imaging results. In addition to the presentation of the cases, a description of the three characteristic fragments of this type of acetabular fractures, the approach pathway, and the reduction sequence performed are made. From the results obtained and the associated advantages, the authors believe that the addition of the iliac crest approach to the Kocher-Langenbeck pathway may be a very attractive option to consider in the surgical treatment of properly selected fractures of two columns of the acetabula.

Resumo As fraturas de duas colunas do acetábulo segundo a classificação de Letournel são das mais comuns em frequência, indicação e complexidade cirúrgica. Estas resultam essencialmente de mecanismos de compressão lateral e caracterizam-se por originarem um acetábulo desconectado do esqueleto axial. O seu tratamento cirúrgico pode incluir: abordagem anterior ou posterior isolada; combinadas, no mesmo tempo cirúrgico ou não; ou abordagens alargadas. Os autores apresentam outra opção cirúrgica com associação de via de Kocher-Langenbeck e abordagem da crista ilíaca simultânea e no mesmo posicionamento (decúbito lateral) com base nos três primeiros casos clínicos realizados e seus resultados clínicos e imagiológicos. Para além da apresentação dos casos, é feita uma descrição dos três fragmentos característicos deste tipo de fraturas acetabulares, da via de abordagem e da sequência de redução realizada. Pelos resultados obtidos e vantagens associadas, os autores acreditam que a adição da abordagem da crista ilíaca à via de Kocher-Langenbeck pode ser uma opção muito atrativa a ter em conta no tratamento cirúrgico de fraturas de duas colunas do acetábulo devidamente selecionadas.

A Novel Method of Treatment of Small Osteolabral Avulsions Associated with Posterior Fracture dislocation of the Hip / Um novo método de tratamento de pequenas avulsões osteolabrais associadas a fratura-luxação posterior do quadril

Abstract Small osteolabral avulsions of the hip can be easily missed, and postreduction stress testing and computed tomography (CT) scans of the hip should be performed to look for these injuries. The usual modality of treatment of these unstable osteolabral avulsions is suture anchors, Herbert screws or spring plates. But when the bony avulsion is small, the use of these implants becomes a tedious job. We present a novel technique to fix small osteochondral avulsion fractures not amenable to fixation using screws or spring plates. We performed a retrospective analysis of 57 cases of patients who underwent open reduction and internal fixation for posterior fracture dislocation of the acetabulum, and we identified 6 cases of small posterior labral osteochondral fragments leading to instability. These injuries were fixed using a novel method. The mean Harris Hip Score at the final follow-up was of 92.5. Fixation of osteochondral avulsions associated with posterior hip fracture dislocation can be a difficult task if the bony fragment is small. Our technique is a simple, cost-effective and reliable way of fixing such avulsions with satisfactory outcomes.

Resumo Pequenas avulsões osteolabrais do quadril podem passar despercebidas, e testes de estresse pós-redução e tomografia computadorizada do quadril devem ser realizados para sua detecção. O tratamento dessas avulsões osteolabrais instáveis geralmente é feito com âncoras de sutura, parafusos de Herbert ou placas-molas. Em avulsões ósseas pequenas, porém, o uso desses implantes é um trabalho tedioso. Apresentamos uma nova técnica de fixação de pequenas fraturas com avulsões osteocondrais não passíveis de fixação com parafusos ou placas-molas. Realizamos uma análise retrospectiva de 57 casos de pacientes submetidos à redução aberta e fixação interna de fratura-luxação posterior do acetábulo, e identificamos 6 casos em que um pequeno fragmento osteocondral labral posterior causava instabilidade. Essas lesões foram corrigidas com um novo método. A pontuação média no Harris Hip Score no último acompanhamento foi de 92,5. A fixação de avulsões osteocondrais associadas a fratura-luxação posterior do quadril pode ser difícil se o fragmento ósseo for pequeno. Nossa técnica é uma maneira simples, econômica e confiável de corrigir tais avulsões com resultados satisfatórios.

Violencia y maltrato infantil. El aporte del médico radiólogo al abordaje integral multidisciplinario / Child maltreatment and violence. Contributions from radiologists to a comprehensive multidisciplinary approach

El maltrato infantil es definido por la Organización Mundial de la Salud (OMS) como "el abuso y la desatención que sufren los niños menores de 18 años. Incluye todo tipo de maltrato físico y/o emocional […] que resulte en un daño real o potencial para la salud, la supervivencia, el desarrollo o la dignidad del niño". Al examinar los rastros corporales del maltrato físico, siguiendo los mecanismos de lesión más frecuentemente implicados, es posible detectar patrones radiológicos típicos. La evaluación imagenológica del hueso en reparación permite inferir cronologías para correlacionar con los datos obtenidos en la anamnesis. Los profesionales de la salud deben detectar oportunamente lesiones radiológicas sospechosas y activar de forma temprana el resguardo del menor. Nuestro propósito es realizar una revisión sobre las publicaciones recientes referidas al estudio imagenológico en niños de quienes se sospeche que puedan ser víctimas de violencia física.

The World Health Organization (WHO) defines child maltreatment as "the abuse and neglect that occurs to children under 18 years of age. It includes all types of physical and/or emotional ill-treatment [...], which results in actual or potential harm to the child's health, survival, development or dignity." By examining the bodily traces of physical abuse, following the most frequently involved mechanisms of injury, it is possible to identify typical radiological patterns. The imaging studies of the bone under repair allows inferring a timeline that may be correlated to the data obtained during history taking. Health care providers should detect suspicious radiological lesions in a timely manner and promptly activate the safeguarding of the child. Our objective was to review recent publications on the imaging studies of children suspected of being victims of physical violence.

INTRODUCTION Distal femoral fractures (DFF) are a relevant problem for public health worldwide. As the population ages, an increase in the rate of these lesions is expected in the next few years. Objective To describe the complications and mortality from DFF in geriatric patients. MATERIALS AND METHODS A descriptive and retrospective study with patients aged 60 years or older who underwent surgery due to DFF. All subjects received treatment in the same trauma center from 2011 to 2015 and underwent a minimum follow-up of 1 year. Patients with incomplete medical records were excluded. We analyzed demographics, radiological findings, local and systemic complications, length of stay, and mortality rates. RESULTS In total, 16 patients met the inclusion criteria; their median age was of 72 (range: 61 to 93) years, and 14 subjects (87,5%) were female. The classification of the Association for the Study of Internal Fixation (Arbeitsgemeinschaft für Osteosynthesefragen, AO, in German) was as follows: A ­ 12 patients (75%); B ­ 2 patients (12.5%); and C ­ 2 patients (12.5%). There were no open fractures. The devices used in the operations included dynamic condylar screw (DCS) plates (9 subjects; 56%), distal femur locking compression plates (LCPs) (4 subjects; 25%), and retrograde distal femoral nails (DFNs) (3 subjects; 19%). The median time until surgery was of 10 (range: 3 to 27) days, with a median length of stay of 14 (range: 5 to 47) days. Complications were presented by 6 (37.5%) patients: 2 (12.5%) cases of pulmonary thromboembolism and 4 (25%) cases which required reintervention (2 due to hardware failure, 1 because of arthrofibrosis, and 1 due to aseptic nonunion); there were no cases of infection. The mortality rate at 12 months was of 0%. CONCLUSION The patients with DFF in this geriatric cohort presented a long length of stay, with a high rate of complications, including a rate of 25% of reintervention. Nevertheless, the 1-year mortality rate was of 0%

Análise epidemiológica das fraturas de mão em um hospital terciário / Epidemiological analysis of hand fractures in a tertiary hospital

Introdução: O trauma de mão constitui uma epidemia, ocorrendo por diversos fatores, como acidentes de trabalho e violência urbana. Isso gera um impacto significativo por ser uma unidade anatômica vulnerável e importante na realização de atividades cotidianas e para o trabalho. Desse modo, faz-se necessária uma avaliação epidemiológica mais aprofundada no que tange, sobretudo, às fraturas de mãos, entendendo sua elevada morbidade. Método: Estudo descritivo e retrospectivo, feito por análise de prontuários de pacientes conduzidos em um hospital terciário no período de janeiro de 2018 a dezembro de 2020. Resultados: Participaram do estudo 290 pacientes, sendo 85,7% do sexo masculino e 14,3% do sexo feminino. 138 indivíduos tinham entre 20 e 39 anos, representando um total de 47,6%. 51,6% eram do interior do estado do Ceará e 48,4% eram da capital. O principal mecanismo de trauma associado às fraturas foram os acidentes de trânsito (36,4%), seguidos por acidentes de trabalho (26,9%) e ferimentos por arma de fogo (14%). Em relação aos ossos fraturados, houve uma acentuada prevalência do acometimento das falangeanas, em todas as faixas etárias, representando 210 pacientes (72,4%). Conclusão: O presente estudo corrobora com os dados presentes na literatura. Desse modo, é evidenciada a repetição de prevalência de faixa etária, principais mecanismos de trauma envolvidos, bem como ossos acometidos nas fraturas de mão.

Introduction: Hand trauma is an epidemic occurring due to several factors, such as work accidents and urban violence. This significantly impacts it as it is a vulnerable and important anatomical unit for daily activities and work. Therefore, a more in-depth epidemiological assessment is necessary regarding hand fractures and understanding their high morbidity. Method: A descriptive and retrospective study was conducted by analyzing the medical records of patients treated in a tertiary hospital from January 2018 to December 2020. Results: 290 patients participated in the study, 85.7% male and 14.3 % female. One hundred thirty-eight individuals were between 20 and 39 years old, representing 47.6%. 51.6% were from the interior of the state of Ceará, and 48.4% were from the capital. The main trauma mechanism associated with fractures was traffic accidents (36.4%), followed by work accidents (26.9%) and firearm injuries (14%). Concerning fractured bones, there was a marked prevalence of phalangeal involvement in all age groups, representing 210 patients (72.4%). Conclusion: The present study corroborates the data present in the literature. In this way, the repetition of the prevalence of age group, main trauma mechanisms involved, as well as bones affected by hand fractures is evidenced.

Abordagem cirúrgica de fratura blow-out através de acesso transconjuntival: relato de caso / Surgical approach to blow-out fracture through transconjunctival access: case report

Introdução: a região orbitária é bastante suscetível a fraturas, devido a sua posição exposta e a ossos frágeis. As fraturas do tipo blow-out caracterizam-se pela fratura do assoalho orbitário com ou sem herniação de conteúdo para o seio maxilar, gerando consequências funcionais e estéticas. Relato do caso: paciente do sexo feminino, 48 anos de idade, vítima de queda da própria altura, compareceu ao Hospital Geral do Estado da Bahia com queixa de diplopia, apresentando fratura de assoalho de órbita direita. Foi programada uma abordagem transconjuntival e instalação de tela de titânio para reconstrução. Na alta hospitalar, a paciente negou diplopia, não apresentando prejuízos funcionais ou estéticos. Conclusão: o acesso transconjuntival possibilita uma adequada exposição do assoalho de órbita, para colocação de telas, deixando uma cicatriz imperceptível na conjuntiva. Apesar das vantagens, este acesso cirúrgico apresenta maior complexidade técnica, sendo pouco realizado pelos cirurgiões

Introduction: the orbital region is very susceptible to fractures due to its exposed position and fragile bones. Blow-out fractures are characterized by fractures of the orbital floor with or without herniation of contents to the maxillary sinus, generating functional and aesthetic consequences. Case report: a 48-year-old female patient, victim of a fall from her height, presented to the General Hospital of the State of Bahia complaining of diplopia, presenting with a fracture of the floor of the right orbit. A transconjunctival approach and installation of titanium mesh for reconstruction were scheduled. At hospital discharge, the patient denied diplopia, with no functional or aesthetic impairments. Conclusion: the transconjunctival approach allows adequate exposure of the orbital floor for mesh placement, leaving an imperceptible scar on the conjunctiva. Despite the advantages, this surgical approach presents greater technical complexity and is rarely performed by surgeons.

Efecto del shiatsu sobre el dolor en personas con fracturas de extremidades: ensayo clínico / Efeito do shiatsu sobre a dor de pessoas com fraturas nos membros: ensaio clínico / Effects of shiatsu on pain in people with limb fractures: clinical trial

The postoperative period for limbs fractures is characterized by different levels of pain intensity. Shiatsu is a therapy applied with the hands on meridians and tsubos (points similar to acupuncture) related to pain. Objective: To evaluate the effect of shiatsu on postoperative pain in men with arm and leg fractures. Method: Non-randomized and uncontrolled clinical trial, with assessment of pain levels using the Visual Numerical Scale (VNS) (0­10) and measurement of salivary cortisol. The R software and the Wilcoxon test and Fisher's exact test were used. Results: 41 people participated in the research; the initial mean value of salivary cortisol concentration was 0.39 µg/dl and, after shiatsu intervention, it decreased to 0.32 µg/dl (p<0.0001). The Mean pain value was 4.93 (VNS) before the intervention and 3.90 (p<0.0001) after. Conclusion: The application of shiatsu contributed to reducing pain and cortisol levels in people undergoing orthopedic surgery. (AU)

Osteomielitis, perimplantitis y fractura vertical radicular mandibular en un paciente con fibromialgia: presentación de caso / Osteomyelitis, Peri-implantitis and Mandibular Root Vertical Fracture in a Patient with Fibromyalgia: Case Report / Osteomielite, peri-implantite e fratura vertical da raiz mandibular em um paciente com fibromialgia: relato de caso

Introducción: se considera la osteomielitis mandibular un proceso patológico poco frecuente. La mayor parte de los casos presentados involucran pacientes con osteorradionecrosis y aquellos pacientes con ingesta de algunos medicamentos antirresortivos. El objetivo es informar un caso inusual de una paciente con osteomielitis, perimplantitis y fractura vertical radicular con antecedentes de fibromialgia. Presentación del caso: mujer de 70 años de edad, no fumadora ni consumidora de alcohol, que acudió con un dolor posteroinferior izquierdo de un año de evolución. Presentaba una profundidad de son-deo mayor de 12 mm en el órgano dental (od) 37, sangrado a la palpación, dolor y movilidad grado ii. En el od 36 fue notoria la exposición clínica del tercio superior del implante dental, sin movilidad, con una profundidad de 4 mm. El tratamiento consistió en una exodoncia atraumática del od 37, donde se identificó una fractura radicular vertical. Discusión: actualmente, los implantes dentales permiten restablecer la salud bucodental. Sin embargo, ellos también pueden inducir una osteomielitis en los maxilares. La terapia instaurada redujo ostensiblemente la morbilidad del implante dental implicado y regeneró la zona intervenida.

Introduction: Mandibular osteomyelitis is considered a rare pathological process. Most of the cases pre-sented involve patients with osteoradionecrosis and those patients with intake of some antiresorptive drugs. The objective of this report is to report an unusual case of a patient with osteomyelitis, peri-im-plantitis and vertical root fracture with a history of fibromyalgia. Case presentation: A 70-year-old female patient, non-smoker or alcohol consumer, who presented with lower left postero-pain of one year's evolution. She presented a probing depth greater than 12 mm in dental organ (od) 37, bleeding on palpation, pain and grade II mobility. At the level of do 36, the clinical exposure of the upper third of the dental implant was notorious, without mobility, with a depth of 4 mm. The treatment consisted of an atraumatic extraction of do 37, where a vertical root fracture was identified. Discussion: Currently, dental implants make it possible to restore oral health. However, they can also induce osteomyelitis in the jaws. The established therapy ostensibly reduced the morbidity of the involved dental implant and regeneration of the intervened area

O objetivo deste relato é relatar um caso incomum de um paciente com osteomielite, periimplantite e fratura radicular vertical com histórico de fibromialgia. Apresentação do caso: paciente do sexo feminino, 70 anos, não fumante ou etilista, que apresentou dor póstero-infe-rior esquerda com um ano de evolução. Apresentava profundidade de sondagem maior que 12 mm no órgão dentário (od) 37, sangramento à palpação, dor e mobilidade grau ii. Ao nível de do 36, foi notória a exposição clínica do terço superior do implante dentário, sem mobilidade, com profundidade de 4 mm. O tratamento consistiu em uma extração atraumática de do 37, onde foi identificada uma fratura vertical da raiz. Discussão: atualmente, os implantes dentários possibilitam o restabelecimento da saúde bucal. No entanto, eles também podem induzir osteomielite nos maxilares. A terapia instituída reduziu ostensivamente a morbidade do implante dentário envolvido e a regeneração da área intervencionada

A comparative study on the functional outcomes of patients who underwent internal versus external fixation for Tibial Plateau fractures two years post-surgery

Introduction@#Tibial plateau fractures are due to high energy trauma brought about by axial compression forces and associated varus or valgus component. @*Objective@#Patients diagnosed with tibial plateau fractures from January to December 2018 treated with internal vs. external fixation will be described according to their Schatzker classification. The study further aims to compare the functional outcomes between the two groups in terms of surgery done. @*Methods@#A chart review determined the distribution of demographics. The Modified Rasmussen Score (MRS) was used to determine the clinical and radiographic parameters after taking a new knee radiograph and assessment from the rehabilitation department. The MRS determined the functional outcomes of the said patients. Ethical considerations and proper informed consent were upheld after being reviewed by the hospital’s research committee. @*Results@#Out of 48 patients, 35 underwent internal fixation via open reduction using plates and/or screws, while 13 underwent external fixation using hybrid external fixator. The demographic profile showed mostly males between ages 20 to 49 years old. Most cases were due to vehicular accidents affecting the left lower extremity. In terms of Schatzker classification, the most common was type VI. The computed mean MRS of the internal fixation group was 30.43 while the external fixation group was 30.00, generally showing no significant difference. @*Conclusion@#Surgical intervention of tibial plateau fractures aims for anatomic reduction using internal or external fixation. There was no significant difference on the functional outcome of the two groups despite classifying the respondents according to Schatzker type, hence we can conclude that external fixation be chosen as the treatment of choice for tibial plateau fractures when properly indicated.

Vertebral fractures combined with prolonged activated partial prothrombin time:A case report / 北京大学学报(医学版)

With the development of modern medical standards,autoimmune diseases and their associ-ated successive osteoporosis have received increasing attention in recent years.Patients with autoimmune diseases,due to the characteristics of the disease and the prolonged use of glucocorticoid hormone thera-py,may affect the bone formation and bone absorption of the patient,followed by severe successive osteo-porosis,thereby increasing the risk of osteoporotic vertebral fractures.Vertebral compression fractures of the spine are common fracture types in patients with osteoporotic fractures.Osteoporosis is a common complication after glucocorticoid therapy in patients with autoimmune diseases.Percutaneous vertebro-plasty(PVP)and percutaneous kyphoplasty(PKP)are minimally invasive operation and are commonly used surgical methods for the treatment of osteoporotic vertebral compression fractures.However,due to the operation of spinal puncture during the operation,there are serious surgical risks such as bone cement leakage,spinal epidural hemorrhage,subdural hemorrhage,and subarachnoid hemorrhage in both PVP and PKP.As a result,it is necessary to evaluate the patient's body before surgery carefully,especially in the case of blood coagulation.This article reports a case of autoimmune disease patient admitted to Peking University People's Hospital due to lumbar 4 vertebral compression fracture combined with Sj?gren's syn-drome.The patient's preoperative examination showed that the activated partial thromboplastin time(APTT)was significantly prolonged.After completing the APTT extended screening experiment and lu-pus anticoagulant factor testing,the multi-disciplinary team(MDT)of Peking University People's Hospi-tal jointly discussed the conclusion that the patient's test results were caused by an abnormal self-immuni-ty anti-copulant lupus(LAC).Based on the results of the laboratory examination,the patient was con-sidered to be diagnosed with combined antiphospholipid syndrome(APS).For such patients,compared with the patient's tendency to bleed,we should pay more attention to the risk of high blood clotting in the lower limbs of the patient,pulmonary clots and so on.With timely anti-coagulation treatment,the patient safely passed the peripheral period and was successfully discharged from the hospital.Therefore,for pa-tients with autoimmune diseases with prolonged APTT in the perioperative period,doctors need to careful-ly identify the actual cause and carry out targeted treatment in order to minimize the risk of surgical and perioperative complications and bring satisfactory treatment results to the patients.

Application of artificial bone material in percutaneous vertebroplasty treatment for osteoporotic vertebral compression fractures / 国际外科学杂志

Objective:To explore the clinical efficacy of combined use of artificial bone materials in percutaneous vertebroplasty (PVP) for osteoporotic vertebral compression fractures (OVCF).Methods:One hundred and eighty-four consecutive patients with OVCF admitted to Beijing Friendship Hospital, Capital Medical University from June 2020 to June 2021 were retrospectively analyzed. All patients had single-level fracture and treated with PVP. According to whether artificial bone materials were used, the patients were divided into experimental group ( n=95) and control group ( n=89). The experimental group was treated with bone cement mixed with artificial bone materials, and the control group was treated with bone cement. The following indices were observed in the two groups before surgery and at 3 days, 3 months, 12 months (final follow-up) after surgery: visual analogue scale (VAS) score, Oswestry disability index (ODI), Cobb angle of kyphosis, and the percentage of anterior vertebral height, the amount of bone cement injected, postoperative complications and adjacent vertebral fractures were recorded. Measurement data were expressed as mean±standard deviation ( ± s), and t-test was used for comparison between groups; Chi- test was used for comparison between groups for count data. Results:All patients successfully completed the operation and were followed up for 12-20 months, with a mean follow-up of (14.24±2.51) months. The VAS score at 3 days, 3 months after operation and final follow-up (experimental group: 2.00±0.71, 1.89±0.71, 1.41±0.49; control group: 2.13±0.73, 1.81±0.60, 1.44±0.50) and ODI index at 3 months after operation and the final follow-up [experimental group: (21.56±4.68)%, (23.22±4.11)%; control group: (22.46±3.74)%, (22.39±4.05)%] were significantly improved compared with those before operation [VAS, experimental group: 7.66±0.86, control group: 7.81±0.89; ODI, experimental group: (70.11±8.24)%, control group: (68.97±8.59)%], and the differences were statistically significant ( P<0.05). There were no significant differences in the amount of bone cement injected between the two groups ( P>0.05). There was no significant difference in the Cobb angle of kyphosis and the percentage of anterior vertebral height at each time point ( P>0.05). The incidence of bone cement leakage in the experimental group was 15.8% (15/95), slightly lower than that in the control group [22.5% (20/89)], but the difference was not statistically significant ( P>0.05). As of the final follow-up, the incidence of adjacent vertebral fracture in the experimental group was 8.4% (8/95), which was lower than that in the control group (19.1%, 17/89), and the difference was statistically significant ( P< 0.05). Conclusion:The application of bone cement mixed with artificial bone materials in PVP for OVCF, can achieve good clinical efficacy, and reduce the incidence of adjacent vertebral fractures.

Comparison of clinical outcome between the percutaneous pedicle screw fixation and Wiltse approach for the treatment of thoracolumbar fractures without neurological injury / 国际外科学杂志

Objective:To compare the safety and efficacy of two different minimally invasive approaches to implant pedicle screw for the treatment of single-segment thoracolumbar spine fractures without nerve injury.Methods:This was a retrospective study. Eighty patients with mono-segmental thoracolumbar fractures treated with minimally invasive pedicle screw fixation at Beijing Friendship Hospital, Capital Medical University from January 2020 to June 2022 were included. There were 46 males and 36 females, the age was (45.93±7.91) years old, and ranged from 27 to 60 years old. They were divided into two groups according to different surgical techniques: percutaneous pedicle screw fixation group ( n=44) and Wiltse approach group ( n=36). The operative time, operative visible blood loss, hidden blood loss, total blood loss, fluoroscopy times, incision length, hospital time after surgery and ambulation time were compared. Visual analogue scale (VAS), Oswestry disability index (ODI), ratio of the vertebral anterior height, angle of injured vertebral endplate were recorded and compared between two groups before surgery and at 3 days, 6 months and 1 year after surgery. The accuracy of pedicle screw position and the facet joint violation rate were evaluated by using the postoperative CT scan. Perioperative related complications were investigated. Normally distributed numerical data were presented as mean ± standard deviation, and differences between the groups were compared using t-test. The counting data were expressed as percentages or rates and compared using χ2 test. Results:All patients were followed for a minimum of 12 months. There is no significant difference between the two groups in intraoperative visible blood loss, hospital time after surgery, ambulation time, postoperative VAS and ODI, ratio of vertebral anterior height and angle of injured vertebral endplate at 3 days after surgery, pedicle screw position accuracy and perioperative complications ( P>0.05). The operative time, hidden blood loss, total blood loss, intraoperative fluoroscopy times, facet joint violation rate in the percutaneous pedicle screw fixation group were remarkably higher than in the Wiltse approach group ( P<0.05). The ratio of vertebral anterior height in the percutaneous pedicle screw fixation group was dramatically lower than in the Wiltse approach group at 6 months and 1 year after surgery ( P<0.05). The postoperative injured vertebral endplate angle was higher in the percutaneous pedicle screw fixation group than that in the Wiltse approach group at 6 months and 1 year ( P<0.05). Conclusions:Both percutaneous pedicle screw fixation and Wiltse approach were safe and effective minimally invasive surgical procedures for the treatment of thoracolumbar fractures without neurological injury. The Wiltse approach can reduce fluoroscopy times and perioperative hidden blood loss, reduce the risk of facet joint violation, and maintain a better reduction than percutaneous pedicle screw fixation.

Clinical progress of internal fixation in the treatment of femoral neck fracture in middle-aged and elderly patients / 国际外科学杂志

Middle-aged and elderly patients with femoral neck fracture often suffer from basic diseases. Conservative treatment will significantly increase the incidence of complications. At present, surgical treatment is mostly advocated. Internal fixation is one of the effective treatment methods for middle-aged and elderly patients with femoral neck fracture. It has the advantages of improving hip joint function, accelerating patient recovery, and improving patient quality of life. At present, there are many choices of internal fixation in the world, each has its own advantages and disadvantages, and there is no unified standard. Different surgical methods can be selected according to various factors such as fracture type, patient′s physical condition and surgical auxiliary technology. This article reviews the clinical progress of internal fixation for femoral neck fractures in middle-aged and elderly patients from four aspects: the characteristics of femoral neck fractures in middle-aged and elderly patients, common internal fixation methods, 3D printing guide plate auxiliary technology and artificial intelligence auxiliary technology.

Research progress of bionic intramedullary nail of proximal femur based on "lever-fulcrum balance and reconstruction" theory in the treatment of senile intertrochanteric femoral fractures / 国际外科学杂志

Femoral intertrochanteric fracture is one of the common types of fractures in the elderly. With the general improvement of medical and living standards, the number of elderly people is increasing, and the problem of osteoporosis has also become relatively prominent. Therefore, low violence can usually cause fractures in this area of the elderly, which has a significant negative impact on the quality of life of elderly patients. With the further development of medical technology and internal fixation materials, the emergence of proximal femoral nail antirotation(PFNA) has greatly improved the treatment effect of femoral intertrochanteric fractures in elderly patients. However, with the increasing number of patients treated, internal fixation failures have gradually been reported. In recent years, proximal femoral biomimetic intramedullary nail(PFBN) has been reported to have good clinical efficacy. Therefore, this article mainly elaborates on the theoretical basis, design characteristics, biomechanics, and clinical efficacy research of PFBN, providing more reference for the clinical treatment of femoral intertrochanteric fractures in elderly patients in the future.

Genome wide association study on genetic risk factors of deep vein thrombosis after trauma / 临床检验杂志

Objective To investigate the genetic risk factors of deep vein thrombosis(DVT)after trauma.Methods In a nested case-control study,50 patients with DVT after traumatic lower extremity fractures and 50 patients without DVT were recruited.The two groups were matched with gender,age and fracture sites.Preoperative venography was performed to diagnose DVT in trauma patients.Genome wide association study(GWAS)was used to investigate the genetic risk factors for preoperative DVT after traumatic lower ex-tremity fractures.Genomic DNA in leukocytes from blood sample was extracted and used for GWAS.Results GWAS was conducted based on 2 662 single nucleotide variants(SNV)which were dispersed in 144 interested genes.Ten genes were found to have signifi-cant association with trauma-related DVT,including cofactors of hemostasis mechanism,i.e.,THBD,F5,SERPIND1 and ITGA2,the factors related to vitamin K-dependent(VKD)carboxylation,i.e.,GGCX and CALU,and the members of cytochrome P450 family,i.e.,CYP1A1,CYP3A4,CYP2C19 and CYP2B6.Conclusion DVT after trauma might be regulated by the cofactors of hemostasis mechanism,the factors related to VKD carboxylation and the members of cytochrome P450 family.The results of our study may provide reference and inspiration for genetic susceptibility of preoperative DVT after trauma.

Construction of artificial intelligence-based prediction models for non-recognizable thoracolumbar compression fractures by X-ray inspection / 实用放射学杂志

Objective To evaluate the potency of applying an artificial intelligence(AI)based model for classifying vertebral fractures in lumbar X-ray images.Methods Patients who underwent lateral lumbar X-ray and MRI were retrospectively selected.Based on MRI results,the vertebrae were categorized as fresh fractures,old fractures,and normal vertebrae.A ResNet-18 classification model was constructed using delineated region of interest(ROI)on the X-ray images,and the model's performance was evaluated.Results A total of 272 patients(662 vertebrae)were included in this study.The vertebrae were randomly divided into training(n=529)and validation(n=133)sets.The model's performance in discerning normal vertebrae,fresh fractures,and old fractures revealed accuracy of 0.91,0.42,and 0.75,and the sensitivity were 0.91,0.408,and 0.72,while the specificity were 0.796,0.892,and 0.796,respectively.Conclusion The X-ray-based ResNet-18 AI model has significant accuracy for distinguishing old fractures and normal vertebrae;However,the model's accuracy needs further improvement for distinguishing fresh fractures.

Relationship between perioperative nutrition risk and venous thromboembolism in patients with hip fracture / 天津医药

Objective To investigate the relationship between perioperative nutritional risk and venous thromboembolism(VTE)in patients with hip fracture.Methods A total of 379 patients with unilateral hip fracture due to fall or sprain who underwent elective surgery were selected and divided into the non-VTE group(246 cases)and the VTE group(133 cases)according to whether or not VTE occurred during perioperative period.Basic information,surgical and anesthesia records,nutritional risk related indicators,inflammatory indicators and outcome indicators of patients were collected.Multiple Logistic regression was used to analyze the independent influencing factors of perioperative VTE.Receiver operating characteristics(ROC)curves were used to assess the ability to discriminate independent factors,and DeLong test was used to compare area under the curve(AUC).Results Compared with the non-VTE group,the proportion of patients in the VTE group was older,complicated with hypertension,the time to visit hospital more than 2 days,received(hollow/intramedullary nail)internal fixation,perioperative blood transfusion,ASA gradeⅢtoⅣ,and higher nutritional risk screening Table(NRS)-2002 scores on admission and higher postoperative neutrophil/lymphocyte ratio(NLR).Nutritional prognosis index(PNI),hemoglobin(Hb)and prealbumin(PA)at admission and after operation were lower in the VTE group than those in the non-VTE group(P＜0.01).Multivariate Logistic regression analysis showed that PNI was decreased,NRS-2002 scores and PA were increased,and the time of visit hospital was>2 days after internal fixation.American College of Anesthesiologists(ASA)gradesⅢ-Ⅳwere independent risk factors for perioperative VTE of hip fracture(P＜0.05).ROC curve analysis showed that the AUC(95%CI)of NRS-2002 at admission was 0.739(0.692-0.783),and that of PNI at admission was 0.720(0.672-0.765),both of which were better than other influencing factors(P＜0.01).Conclusion NRS-2002 and PNI are good predictors of perioperative VTE in patients with hip fracture.
