OBJECTIVE: To explore the mid-term effectiveness of total hip arthroplasty (THA) with subtrochanteric shortening osteotomy in treatment of Crowe type Ⅳ developmental dysplasia of the hip (DDH).
METHODS: Between September 2009 and March 2014, a total of 49 patients (57 hips) who were diagnosed with Crowe type Ⅳ DDH were treated with THA and subtrochanteric shortening osteotomy. Of the 49 patients, 7 were male and 42 were female with an average age of 44.6 years (range, 20-73 years). The preoperative Harris score was 44.68±3.39 and the preoperative leg length discrepancy was (5.27±0.55) cm.
RESULTS: All incisions healed primarily. All patients were followed up 32-87 months (mean, 52.1 months). At last follow-up, the Harris score was 85.67±2.89 and the leg length discrepancy was (1.12±0.48) cm, showing significant differences when compared with the preoperative values ( t=-69.53, P=0.00; t=42.94, P=0.00). X-ray films showed that bone union of the femoral osteotomy end at 6 months after operation. There was no loosening and subsidence of prosthesis at last follow-up.
CONCLUSION: The subtrochanteric shortening osteotomy with THA in treatment of Crowe type Ⅳ DDH can obtain satisfactory mid-term effectiveness with low risk of peripheral vascular and nerve traction injuries.
