“…Using anteroposterior, lateral, and oblique highresolution digital radiography (MX-20; Faxitron, Wheeling, IL), fractures were categorized according to the Orthopaedic Trauma Association (OTA) classification system (28,29). The goal was to create tibial plateau intraarticular fractures of lower fracture energies and "moderate" severity (OTA classes B1 and B2).…”

Objective. Posttraumatic arthritis is a frequent long-term complication of intraarticular fractures. A model of a closed intraarticular fracture in C57BL/6 mice that progresses to posttraumatic arthritis has been developed. The MRL/MpJ mouse has shown unique regenerative abilities in response to injury. The objective of this study was to determine if the MRL/MpJ mouse is protected from posttraumatic arthritis after intraarticular fractures.Methods. Intraarticular fractures were created in MRL/MpJ mice and C57BL/6 control mice (n ‫؍‬ 16 each). Limbs were analyzed for posttraumatic arthritis 4 and 8 weeks after fracture using microfocal computed tomography bone morphology, subchondral bone thickness evaluation, and histologic evaluation of cartilage degeneration. Serum cytokines and biomarkers were measured after the mice were killed.Results. Intraarticular fractures were successfully created in all 32 mice. In the experimental fractured limbs, C57BL/6 mice had a decrease in bone density, increased subchondral bone thickness, and increased cartilage degeneration compared with normal contralateral control limbs. In the MRL/MpJ mice, no differences in bone density, subchondral bone thickness, or histologic grading of cartilage degeneration were seen between fractured and contralateral control limbs. Cytokine analysis showed lower systemic levels of the proinflammatory cytokine interleukin-1␣ (IL-1␣) and higher levels of the antiinflammatory cytokines IL-4 and IL-10 in the MRL/MpJ mice.Conclusion. This study shows that the MRL/MpJ mouse is relatively protected from posttraumatic arthritis after intraarticular fracture. Further investigation into the mechanism involved in this response will hopefully provide new insight into the pathogenesis, prevention, and treatment of posttraumatic arthritis after intraarticular fracture.

“…4,5 The Schatzker classification is most widely used for preoperative planning. 6,7 Both conservative and operative treatments have achieved good results for tibial plateau fractures. 8,9 Surgical treatment is recommended for fractures with >5 mm displacement or >5º varus or valgus in order to restore joint congruity and limb alignment and enable early knee mobilisation.…”

purpose. To evaluate radiological and clinical outcome of minimally invasive plate osteosynthesis (MIPO) for tibial plateau fractures. Methods. 35 men and 6 women aged 19 to 75 (mean, 40; standard deviation [SD], 14) years underwent MIPO for displaced tibial plateau fractures. According to the Schatzker system, the tibial plateau fractures were classified as types I (n=3), II (n=9), III (n=11), IV (n=6), V (n=7), and VI (n=5). Six patients had open fractures; 2 of them underwent debridement before MIPO. 10 patients needed additional bone grafting. Radiological (at immediate postoperation) and clinical (at the 12-month follow-up) assessments based on the Rasmussen anatomic and functional scoring system were recorded using a proforma. Patients with acceptable and unacceptable outcomes were compared in terms of age. results. The mean Rasmussen anatomic score was 15.1 (SD, 2.2; range, 10-18); the mean Rasmussen functional score was 25.3 (SD, 3.2; range, 14-29); and

RESUMOObjetivo: Avaliar a concordância interobservador de três classificações utilizadas para a fratura do platô tibial: Schatzker, Grupo AO e Hohl. Método: Nove observadores, subdivididos de acordo com o grau de titulação (seis médicos residentes -MR -e três médicos especialistas -ME), classificaram 50 fraturas do platô tibial. A concordância interobservador foi avaliada pelo coeficiente Kappa. Resultados: Comparando-se os médicos residentes (MR) com os médicos especialistas (ME), observou-se que as três classificações apresentaram concordância de grau fraco e moderado. Entre os MR, as classificações do Grupo AO e de Hohl mostraram relação direta entre aumento no grau de concordância e ano de residência médica, o que foi observado de forma parcial para a classificação de Schatzker. Para a classificação de Hohl, o Kappa variou de 0,344 a 0,577; para a classificação do Grupo AO, variou de 0,36 a 0,499; e para a classificação de Schatzker, variou de 0,278 a 0,465. Conclusão: Existe concordância significativa, ao nível de 1%, entre as três classificações para todos os pares de observadores. Comparando-se os MR com os ME, as três classificações estudadas apresentam concordância de grau fraco e moderado. A classificação de Hohl apresenta a maior concordância entre os MR. Descritores - INTRODUçãOAs fraturas do platô tibial representam 1 a 2% de todas as fraturas e aproximadamente 8% das fraturas em idosos (1) . Por se tratar de fraturas que envolvem a cartilagem articular, necessitam de redução anatômica e mobilidade precoce, que são preferencialmente obtidas por meio cirúrgico (2) . Nesse sentido, a utilização de um sistema de classificação abrangente torna mais compreensível a definição da tática e do acesso cirúrgicos.De forma conceitual, a proposta da adoção de um sistema de classificação passa por sua capacidade de reprodutibilidade, simplicidade e facilidade de memorização, aju-
