The functional outcome of total hip arthroplasty for arthrodesed hips was evaluated. During the years 1979 to 1988, 55 arthrodesed hips were converted to total hip arthroplasties. Thirty-seven women and nine men were followed for a minimum of 5 years. Thirteen of the patients were very much satisfied with the operation, 19 were much satisfied, 7 were satisfied, 3 were less satisfied, and 4 were unsatisfied. The Harris hip score was improved from 51-83 at the time of operation to 53-93 at the follow-up examination. Before conversion, none of the patients used crutches. At the follow-up examination, 10 patients used two crutches, 24 used one crutch, and 12 did not need support. Muscle strength of the abductors ranged from 1 to 4. In 26 patients with major low back pain before conversion, the pain score improved from 3-10 at the time of operation to 0-8 at the follow-up examination. This study shows that with conversion of an arthrodesed hip to arthroplasty, most patients need support for walking; however, they are generally grateful for their new mobility, maneuverability, and improved ability to sit comfortably.
对髋关节融合后行全髋关节置换术的功能结果进行了评估。在1979年至1988年期间，55例髋关节融合患者接受了全髋关节置换术。对37名女性和9名男性进行了至少5年的随访。13名患者对手术非常满意，19名比较满意，7名满意，3名不太满意，4名不满意。Harris髋关节评分从手术时的51 - 83分提高到随访时的53 - 93分。转换手术前，没有患者使用拐杖。在随访检查时，10名患者使用双拐，24名使用单拐，12名不需要支撑。外展肌肌力范围为1至4级。在转换手术前有26名患者存在严重腰痛，疼痛评分从手术时的3 - 10分改善到随访时的0 - 8分。这项研究表明，髋关节融合转换为关节置换术后，大多数患者行走需要支撑；然而，他们总体上对新获得的活动能力、机动性以及舒适坐姿的改善心怀感激。
