| Objective To evaluate the effect of repairing hip posterolateral complex（HPLC）with suture anchors to prevent postoperative prosthesis dislocation after bipolar hemiarthroplasty. Methods A retrospective study was designed. From June 2009 to June 2016, 57 senile patients（58 hips）with femoral neck fracture were treated operatively in Mianyang central hospital （Sichuan, China）. There were 23 males and 34 females. 75.5 to 97 years of old（mean, 83.6 years）. There were 12 hips of Garden type II, 27 hips of Garden type III and 19 hips of Garden type IV. The HPLC was repaired with suture anchors after the bipolar prostheses were implanted. Results The 57 patients （58 hips）were evaluated during the hospitalization period and a mean follow up period of 18.3 months（from 6 to 36 months）. Intraoperative hip flexion examination of 100°, the prosthesis dislocation rate was 74.14%（43/58）before repairing HPLC, there was none of prosthesis dislocation after repairing HPLC. No dislocation happened in this group. At the last follow-up, 46 patients had no pain, 10 had mild pain, and 2 had moderate pain. The mean Harris Hip Score was 91.57, functional outcome was excellent in 44 hips, good in 9, fair in 5, giving an excellent to good rate of 91.37％. Conclusion Repairing HPLC with suture anchors was effective to prevent postoperative prosthesis dislocation. |
