Total Hip Arthroplasty for High Positioned Dislocated Hips

Abstract

Total hip arthroplasty (THA) for high positioned dislocated hips was performed on 13 patients. 10 woman and three men. The mean patient age was 59.6 years (range; 44 to 84). Attempts were made to correct the leg-length discrepancy to an appropriate length in each case. The mean lengthening was 43 mm (range; 30 to 65 mm). One patient complained of sural cutaneous nerve palsy due to overlengthening of the femur, and two patients complained of numbness in the femur nerve area. We consider that the appropriate leg-lengthening to be within 50 mm.
