    Abstract:
    OBJECTIVE: To explore the effect of improved EPSTR on prevention of dislocation after total hip arthroplasty. METHODS: From January 2006 to May 2007, the posterior structures were repaired using improved EPSTR in 85 cases (87 hips) of total hip arthroplasty, which involved 39 males and 46 females, with an average age of 69.5 years (range, from 62 to 85 years). Fifty-eight cases were of fresh femoral neck fracture, 25 cases were of aseptic necrosis of femoral head, 3 cases were of osteoarthritis, 1 case was of a internal fixation failure of femoral intertrochanteric fracture. RESULTS: All 85 cases were followed up for 8-24 months (average 15 months). None of these 85 patients had posterior dislocation, external rotation contracture and greater trochanter fracture. The Harris score at the 6th month postoperatively was 89.2 +/- 4.5. CONCLUSION: Improved EPSTR is an effective, simple and timesaving method in prevention of dislocation after total hip arthroplasty, it has clinical application value.
