Hip desarthrodesis, which is the conversion of an arthrodesis or of a surgical bone fusion into a hip replacement arthroplasty, is a difficult and challenging operation because of the need of a joint reconstruction in cases with bone fusion and an often long-term immobilization between the femur and the acetabulum, with important anatomic changes, retractions of adjacent soft tissues, and an associated limb shortening. Hip arthrodesis is an operation performed less and less; consequently, its desarthrodesis is even rarer. The present report details three rare cases of patients with long-term hip arthrodesis who were submitted to hip replacement conversion arthroplasty; it describes the applied surgical techniques and their clinical and functional outcomes.
髋关节关节固定术转变为髋关节置换术，即将关节固定术或外科骨融合术转变为髋关节置换术，是一项困难且具有挑战性的手术，因为在骨融合的情况下需要进行关节重建，并且股骨和髋臼之间通常需要长期固定，会出现重要的解剖学变化、相邻软组织的回缩以及相关肢体缩短。髋关节固定术的实施越来越少；因此，其关节固定术转变更为罕见。本报告详细介绍了三例长期髋关节固定术患者接受髋关节置换转变术的罕见病例；描述了所应用的手术技术及其临床和功能结果。
