Aim: The aim of this study was to compare the fixation effects of three fixation devices for tibial plateau fracture (AO/OTA classification 41 A1). Methods: Sixteen human cadaver tibial specimens were randomly divided into four groups. An A1 fracture model was established. The fractures were subsequently fixed by axial controlled intramedullary nail, external fixation and steel plate fixation. Each specimen was subjected to axial compression, torsion test and three-point bending test. Then a rat model was used to evaluate the therapeutic effect of these three fixations by evaluation of callus formation time and healing time. Results: It was found that the axial controlled intramedullary nail group obtained superior biomechanical properties of resistance ability of bending, torsional and axial compressive, compared with external fixation and steel plate group. In animal experiments, the axial controlled intramedullary nail group had a significant shorter callus occurrence and healing time than steel plate and external fixator group. Conclusion: The axial controlled intramedullary nail fixation has a superior biomechanical characteristic and fixation effect for tibial plateau fractures than steel plate and external fixator. © 2014 Surgical Associates Ltd.

Fractures of distal humerus in elderly patients are difficult to treat, as diminished bone mineral quality and increased trauma-associated articular surfaces destruction may make stable joint reconstruction even more difficult. In active patients, internal fixation is still a primary choice because of use age of total elbow replacement, but disagreements have still existed on how to treat these fractures in elderly patients. In the past years, treatment of fractures of distal humerus make much progress, including the introduction of dual plates fixation, widespread application of three-dimensional CT reconstruction, recognition of complicated fractures, understanding of the parallel plate technique, application of periarticular plates, and the selective use of total elbow arthroplasty. This article is an overview in treating options of fracture of distal humerus in the elderly patients by review the civil and overseas involved literatures. Source
