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.
目的
探讨改良的EPSTR对全髋关节置换术后预防脱位的效果。
方法
2006年1月至2007年5月，采用改良的EPSTR修复85例（87髋）全髋关节置换术患者的后方结构，其中男性39例，女性46例，平均年龄69.5岁（范围62至85岁）。58例为新鲜股骨颈骨折，25例为股骨头无菌性坏死，3例为骨关节炎，1例为股骨转子间骨折内固定失败。
结果
85例患者均获随访8至24个月（平均15个月）。85例患者均未发生后脱位、外旋挛缩及大转子骨折。术后6个月Harris评分为89.2±4.5。
结论
改良的EPSTR是预防全髋关节置换术后脱位的一种有效、简便、省时的方法，具有临床应用价值。
