Abstract
BACKGROUND:Extraction of a wel fixed cementless femoral stem or a cemented stem is difficult during revision of total hip arthroplasty. The extended trochanteric osteotomy provides excellent methods, and combining with long-stem cementless prosthesis can better reduce postoperative complications. <br> OBJECTIVE:To retrospectively analyze the recent clinical curative effect after extended trochanteric osteotomy combined with long-stem cementless prosthesis in hip revision. <br> METHODA total of 25 patients undergoing hip revision were selected from the Department of Osteoarthrosis, Pingdingshan First People’s Hospital, China from May 2008 to May 2013. Of them, 17 patients were subjected to the extended trochanteric osteotomy combined with single-incision and double-approaches. The femurs were reconstructed with long-stem cementless prosthesis. Al patients were fol owed-up for 12 to 60 months. Pre-operative and post-operative Harris hip scores, the post-operative complications, the bone cutting length, the length of stem in contact with cortical bone, the length of the end of bone cutting to the end of the prosthesis were recorded. <br> RESULTS AND CONCLUSION:17 patients were fol owed-up. The mean length of bone was 17 cm (15-23 cm). The mean length of stem in contact with cortical bone was 6.4 cm (4-11 cm). The mean length of the end of bone to the end of the prosthesis was 11.5 cm (8-18.5 cm). After fol ow-up, the mean Harris hip scores were improved from (39.0 ± 13.6) scores preoperatively to (75.0 ± 14.9) scores postoperatively (P<0.01). Subsidence occurred in two hips. The cutting sites of 17 cases of extended trochanteric osteotomy were fixed wel . These data suggested that the operation through single-incision and double-approach to the hip, while preserving the attachment of the external rotators and posterior capsule, wil strength rear hip stability and prevent postoperative dislocations. Recent effects were satisfactory, but the long-term outcomes should be further investigated.关键词
