Evaluation of early clinical results of two stage hip replacement after failed internal fixation for femoral neck fractures / 中国骨伤

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the early clinical results of two stage hip replacement after failed internal fixation for femoral neck fractures in young patients.</p><p><b>METHODS</b>From June 2008 to June 2010,24 patients with femoral head necrosis caused by failed internal fixation were treated with hip arthroplasty. Among them, 12 patients were male and 12 patients were female, with an average age of 42.9 years old (ranged, 18 to 58). According to Harris score and X-ray examination, the clinical result was evaluated.</p><p><b>RESULTS</b>Twenty-three cases were followed up with an average age of 34.4 months (ranged, 25 to 48). After operation, 1 case complicated with the dislocation of hip joint. No deep infection of hip joint, prosthetic loosing or peripheral fracture was found. The mean Harris score was 90.9 +/- 4.3, and 18 obtained excellent results, 4 good and 1 fair.</p><p><b>CONCLUSION</b>Although treatment of femoral head necrosis with two stage hip replacement after failed internal fixation is difficult during operation, its early result is satisfactory.</p>
