Abstract：Objective To evaluate the result of total hip arthroplasty in the treatment of protrusio acetabuli. Methods From 2006. 7 to 2012. 12,21 cases(28 hips)of protrusio acetabuli were treated,including 12 males and 9 females with an av-erage age of 56. 3years(range,26 ~ 68years). The preoperative Harris score was 45 ± 3. 3,there were 6 cases of mild,12 mod-erate cases,and 10 severe cases. All patients received total hip arthroplasty with recovery of femoral off set and acetabular cen-ter of rotation. Results All incisions healed without complication of infection,deep venous thrombosis,or nerve injury. All pa-tients were followed up 12 ~ 78 months with an average of 42 months. The Harris score at last follow-up was 87 ± 4. 1,showing significant difference when compared with preoperative score. The X-ray films showed that no prosthesis loosening or subsid-ence was observed,and bone graft healed with no sign of re-protrusion. Conclusion In treatment of protrusio acetabuli,total hip arthroplasty with recovery the femoral off set and acetabular center of rotation and provide satisfactory early result.
