本文旨在研究单侧髋关节脱位,“健侧”出现发育不良的发生率,并对此类髋关节的远期预后进行评估。
选取年-年之间就诊患儿,总共纳入48名(40名女孩,8名男孩)晚期单侧DDH患儿,早期进行皮肤牵引,闭合复位,早期治疗年龄平均为17.8个月(4-65个月),只有1例进行切开复位。25名患儿在复位后3年内需进行“健侧”股骨去旋转手术,10名患儿进行了再次骨盆手术治疗。
对他们幼时和成年后的片子进行回顾,最后拍片子年龄平均为50.9岁(43-55岁),8名(17%)患者出现“健侧”髋关节发育不良,幼时或成年后CE角20°,其中6名进行了再次手术以改善股骨头覆盖,4名行股骨内翻截骨,2名行造盖手术,发育不良均改善。在后期随访,2名患者出现发育不良加重呈现半脱位(CE角分别为4°和5°),均发展成OA,其中1名在49岁时行全髋置换。
总之,“健侧”髋关节的长期预后相对较好,因为平均随访50年,只有2例髋关节发生OA(4%)。“健侧”髋关节需定期复查,当出现半脱位趋势或半脱位时需进行手术治疗。
