[Objective] To evaluate the treatment with total hip arthroplasty(THA)using Zweym?ller system for short females with Crowe-Ⅲ and Ⅳ developmental dysplasia hip(DDH).[Method]From January 2004 to December 2006,thirteen THA procedures were performed in 12 female patients with 13 hips.The age of the patients was from 28 to 62 years old(average 51 years).The height was from 1.48 to 1.55 meters.Based on Crowe classification,8 patients with 9 hips were type-Ⅲ,and 4 patients with 4 hips were type-Ⅳ.before surgery,the discrepancy of lower limbs was from 3 cm to 5 cm.All patieds had severe hip pain and dysfunction.The Harris hip score ranged from 35 to 64 points with 40 points on the average.In all procedures the soft tissue was released entirely,the acetabular component was placed in the true acetabulum without femoral osteotomy.[Result]After operation,the legs lengthened from 2 to 5 cm.During the follow-up of 12 to 36 months(average 24 months),no femoral fracture,femoral or sciatic nerve palsy or loosening was detected except one dislocation according to clinical outcomes and X-ray findings.The Harris score was improved from 60 to 95.There was significant difference between before and after operation(P
