Application EPSTR Technique in Acetabulum Posterior Wall Fracture Fixation

Abstract：Objective To report clinical results of application EPSTR technique after the acetabulum posterior wall frac-ture fixation. Methods From January 2006 to January 2011,46 patients(36 men,10 women)after acetabulum posterior wall fracture fixation underwent posterior soft tissue repair of the hip joint. They ranged in age from 25 to 55 years( mean 42. 5 yeras). Operative time after injury was 3 to 9 days( mean 7 days). Posterior soft tissue of the hip joint was opened through a T-shaped incision. The posterior capsule and short external rotators was attached to the greater trochanter. Results Follow-up period ranged from 2. 5 to 6 years( mean,4. 5 years)postoperatively. There were no dislocation of the hip joint and avascular necrosis of the femoral head in this series. Two patients had osteoarthritis. No apparent complications related to the technique. The recovery rate was accessed with Harris scores. The rates of excellent and good were 93%. Satisfactory clinical results were obtained in this series. Conclusion The acetabulum posterior wall fracture fixation used EPSTR technique help the postopera-tive functional recovery and strengthen stability of the hip joint.
