OBJECTIVE: To analyze the methods of offside reconstruction in total hip arthroplasty (THA) for severe @entity571 . METHODS: Between July 2009 and June 2011, 18 cases (18 hips) of severe @entity570 were treated by @entity2445 , including 14 males and 4 females with a mean age of 55.4 years (range; 47-72 years). The disease duration was 11-74 months (mean, 33.6 months). The left hip was involved in 11 cases and the right hip in 7 cases. The hip Harris score was 34.6    5.3. The lower limb discrepency was observed in 15 cases. Thomas sign, Patrick sign, and Trendelenburg sign were positive in all cases. All @entity1 received THA; during operation, standard femoral neck osteotomy was performed and the correct rotation center was chosen to reconstruct offside. RESULTS: All the incisions healed primarily. Common @entity3030 occurred in 1 case and was cured after symptomatic treatment for 3 months, and the other @entity1 had no complication. The mean follow-up period was 43.5 months (range, 30-53 months). All @entity1 achieved @entity158 relief, and returned to normal gait. The X-ray films showed no @entity572 or prosthetic loosening. @entity6250 was observed in 6 cases. The mean offside difference between normal and ipsilateral side was 0.4 mm (range, 0.1-0.7 mm). At last follow-up, the hip Harris score was 83.0    7.1, showing significant difference when compared with preoperative score (t = -22.96, P = 0.01); the hip range of motion was significantly increased when compared with preoperative one (P < 0.05). CONCLUSION: The offside reconstruction can accurately be carried out by making precise template and vernier caliper measurement, selecting suitable prosthesis preoperatively, maintaining the proper femoral @entity3656 , adjusting the length of the neck and neck-shaft angle, releasing the soft tissue reasonably during THA for severe @entity571 , and the short-term effectiveness is satisfactory.
