Abstract:
Objective To explore the indication, to describe the key of operative technique in detail and to summarize the early results in mini-incision and minimally invasive surgery (MIS) total hip arthroplasty (THA) for hip disorders. Methods From Mar. 2003 to Mar. 2005, 43 patients (49 hips) were performed with MIS THA. The mean age of patients was 53.2 years ranging from 22 to 79 years. There were 22 males and 21 females. The average body mass index (BMI) was 23.4 ranging from 17.1 to 30.2. Using the modified postero-lateral approach, MIS THA was performed with cementless prostheses. For comparison, 35 patients (43 hips) were performed with standard THA at the same period. The age and BMI of patients in both groups were similar, but the pattern of disorders was different. The comparative items included preoperative bleeding, operative time, incisional length, postoperative functional recovery, and prosthetic position. Results 31 patients (MIS THA) and 25 patients (standard THA) were followed from 6 to 24 months (mean 13.1 months). No complications occurred in MIS THA. Dislocation appeared in one patient with standard THA at the two days after operation. The length of incision was 9.3 cm (range, 8.7 to 10.5 cm) in MIS group and 16.8 cm (range, 14 to 20 cm) in standard THA group. The difference was significant statistically (P
