Total hip arthroplasty in the treatment of ankylosing spondilitis with hip ankylosis

Objective To study the curative effect of total hip arthroplasty（THA）in the treatment of ankylosing spondilitis with hip ankylosis.Methods 11 cases of ankylosing spondilitis with hip ankylosis（22 hips） were performed by THA and ankle and foot exercises were done after operation.Results Function of hip joint improved evidently after operation,and flexion deformity disappeared basically.After following up for 2～6 years,there was no sign of loosening,dislocation.The clinical results were evaluated by the Harris hip scoring system.Harris hip score improved from 9~58（36±9.8） points preoperatively to 64~94（81.2±10.6） points at the final postoperatively evaluation.13 hips were excellent effect,6 good and 3 fair.Conclusions THA can greatly improve the function and rectify deformity of hip joint of patients with ankylosing spondilitis with hip ankylosis.The short term curative effect is satisfactory.
