A total of 56 patients were included in the study (67 THAs). The preoperative diagnosis for all patients was osteoarthritis. The average follow-up period was 90 months. No patients developed deep infection during the follow-up period. The maximum mean peak daily temperature was 37.7℃ on the day of the surgery and the next day. Fifty-two percent of patients experienced POF, with most developing a maximum temperature (MT) on the day of surgery and the latest occurring by postoperative day (POD) 3. Only C-reactive protein (R = 0.384, p = 0.001) among the febrile-related factors had a weak correlation with MT. Four hips showed a POF of >38℃ later than POD 7;all four of these patients were diagnosed with a urinary tract infection. POF is common and may be part of a normal inflammatory response to tissue injury after THA. More than half of patients may develop POF within 1 week, with most developing MT on POD 0 and the latest occurring by POD 3. In addition, urinary tract infections might be an initial reason for POF in the subsequent 3 weeks.展开更多

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.展开更多
