Abstract：Objective To evaluate the clinical efficacy of total hip replacement in the treatment of traumat-ic ostcoarthritis ( TOA) after operation of acetabulum dislocation.Methods Twenty seven patients [16 males and 11 females aged from 32-57 years with an average age of (45.2 ±8.7) years] of acetabulum fracture from Mar.2009 to Mar.2013 in our hospital were performed total hip replacement for the treatment of TOA after operation of acetab-ulum dislocation were chosen and their clinical data was retrospectively analyzed.The preoperative and postopera-tive evaluation of hip function were performed and the effect of surgery was completed.Results All patients were successfully operated and all incisions achieved primary healing;postoperative Harris score was 76 to 92,of which 25 patients were more than 80 and the good and excellent rate was 92.6% with an average score of ( 89.1 ±5.78 ) . The difference was significant compared with the preoperative one of (45.3 ±5.86,P<0.05);the flexion,adduc-tion,abduction,external rotation and internal rotation of the joint were greatly different from those before operation with statistical significance(P<0.05).The hip function improved obviously.Conclusion Total hip replacement for the treatment of traumatic ostcoarthritis( TOA) commonly seen after operation of acetabulum dislocation has less postoperative complications and achieves obvious improvement in hip function. It also has clinical advantages of good effect and high patient satisfaction,worthy of clinical popularization and application.
