title: Ultimate outcome in immediate postoperative total hip arthroplasty instability.
abstract: The objective of this study was to determine the ultimate outcome of patients who experienced immediate postoperative instability after primary total hip arthroplasty using regional anesthesia. Thirty-one patients whose radiographs demonstrated dislocation or subluxation immediately after total hip arthroplasty were evaluated as to the ultimate outcome of hip function and stability. Once a dislocation has occurred, the risk of redislocation is high. In this study, of the 29 patients who did not have revisions immediately after surgery, 3 (10.3%) have had recurrent dislocation and 1 (3.5%) has had a subluxation event. Recurrent instability or the need for revision surgery is significantly greater when compared with those patients who have no evidence of postoperative instability.
