Review Case Reports
Recurrent traumatic dislocation of the hip: report of a case and review of the literature.
The case of a twenty-one-year-old female athlete with recurrent traumatic posterior hip dislocation is presented. A simple repair of an inferomedial capsular tear was performed. No bone block was used. ⋯ No avascular changes of the femoral head occurred and minimal formation of ectopic bone was observed. Eighteen months postoperatively, the hip functioned normally and the patient had returned to competitive alpine skiing. The literature on adult recurrent traumatic hip dislocation is reviewed.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparative biomechanical analysis of supracondylar femur fracture fixation: locked intramedullary nail versus 95-degree angled plate.
To compare the initial stability of the genucephalic (GSH) intramedullary nail and the 95-degree condylar compression screw and side plate (DCS) for distal femur fractures. ⋯ Based on the authors' results, the selection of a GSH nail or a DCS plate should not be determined by the severity of the fracture. If a DCS plate construct is selected, the authors recommend a dispersed screw configuration, including the most proximal hole in the plate, to provide superior stiffness in torsional loading and equal stiffness in axial loading when compared with the GSH nail constructs. If a GSH nail is selected, the authors recommend a grouped screw configuration, which absorbed more energy during axial loading compared with the DCS plate constructs and the nail with the dispersed screw configuration.

Randomized Controlled Trial Comparative Study Clinical Trial
Biomechanical evaluation of current patella fracture fixation techniques.
To compare the mechanical effectiveness of three different techniques for stabilization of transverse fractures of the patella. ⋯ Combining interfragmentary screw fixation with the tension band principle appears to provide improved stability over the modified tension band or screws alone for transverse patella fractures. Cannulated screws allow for simple, reliable addition of a tension band to screw fixation.

Randomized Controlled Trial Comparative Study Clinical Trial
Biomechanical comparison of internal fixation techniques for the treatment of unstable basicervical femoral neck fractures.
The optimal method of internal fixation of basicervical femoral neck fractures is controversial. This area represents a transition zone between the intracapsular femoral neck fracture, usually fixed with multiple cancellous screws, and the extracapsular interochanteric fracture, fixed with a sliding screw device [sliding hip screw (SHS)] and derotation screw (DRS) device. The authors' specific aim was to biomechanically compare these two methods of fixation in a cadaveric model of a basicervical femoral neck fracture with posteromedial comminution. ⋯ The results support the use of an SHS and DHS composite compared with three cancellous screws in the treatment of unstable basicervical femoral neck fractures.
