Abstract
We hypothesized that a hip brace may prevent the initial dislocation in the early postoperative period after total hip arthroplasty (THA). We performed a prospective evaluation of the efficacy of a brace in preventing dislocation in 54 primary THAs in 43 patients. All of the patients wore braces for 3 weeks postoperatively. The occurrence of dislocation was evaluated six months postoperatively. There were no cases of dislocation while wearing a brace, while two posterior dislocations occurred 8 and 12 days postoperatively while picking something up from the floor without a brace in so-called provocative positions. The results of this study suggest that a hip brace helps patients to recognize careless provocative positions and prevents the initial hip dislocation in this period instead of usual postoperative management for an average of 6 weeks after discharge, such as a high toilet seat, restricted hip flexion in the activities of daily living, use of a reacher or grabber, an abduction pillow, and a high chair.
Highlights
Postoperative dislocation remains a common major complication after total hip arthroplasty (THA) with an overall incidence of 2% to 3%, but approaching less than 1% after primary THA [1,2,3,4,5,6,7,8,9]

As surgical risk factors are related to the surgical approach, some authors recommend anterior [9] or direct lateral [15] approaches rather than a posterior approach, while others concluded that the posterior, posterolateral, and direct lateral approaches have excellent dislocation rates (
Summary
Postoperative dislocation remains a common major complication after total hip arthroplasty (THA) with an overall incidence of 2% to 3%, but approaching less than 1% after primary THA [1,2,3,4,5,6,7,8,9]. Khatod et al [10] reported dislocation rates of 1.7% for primary THA and 5.1% for revision procedures using contemporary techniques and implants with a community-based registry. It is important to decrease hip dislocation in the early postoperative period. This study was prospectively performed to evaluate the efficacy of bracing at preventing initial dislocations after primary THA during the early postoperative period
