Abstract:
Objective To evaluate the short-term efficacy of total hip arthroplasty combined with subcutaneous osteotomy in the treatment of CroweⅣ hip dysplasia (DDH).Methods From March 2012 to March 2015,14 patients (16 hips) underwent total hip arthroplasty with femoral distraction osteotomy S-ROM femoral stem prosthesis.And we observed its recent efficacy.Results All patients underwent S-ROM prosthesis.The patients underwent transverse osteotomy of the femoral trochanter.The osteotomy length was 2.0-3.5 cm.The average follow-up time was 19 months.And no complications such as dislocation,vascular nerve injury,deep vein thrombosis and infection were observed during the follow-up.The average Harris scores improved from 42.3 preoperatively to 90.4 postoperatively at 9 months after the operation.The average lengths of preoperative limb shortening and postoperative limb shortening were 6.4 cm and 4.3 cm respectively.The X-ray films showed no dislocation of acetabulum and femoral prosthesis.Bone healing was achieved at 6 months after osteotomy.Conclusion This method could be a good choice for Crowe Ⅳ developmental dysplasia.The short-term efficacy is satisfactory.
