摘要

人工髖關節脫臼在全人工髖關節術後是一主要的併發症。對病人身心極為折磨並令其沮喪。我們報告一例78歲女性，在接受左側人工髖關節10年後併有習慣性脫臼及對側人工髖關節鬆脫。她接受使用Trilogy約束型人工髖部關節進行左側人工髖部關節再置換手術後，於36個月的追蹤期間，病人沒有再發生任何的脫臼，並且有滿意的日常生活活動。

Dislocation is one of the major complications resulting from total hip arthroplasty. It is both physically destructive and mentally discouraging. A constrained liner is one of the treatment options for addressing dislocation in some selected patients. A 78-year-old woman presented with late habitual hip dislocation. Her medical history revealed that she had undergone a left total hip replacement 10 years earlier. Physical examination revealed pain in the right thigh and a limping gait caused by the loosening of the femoral stem following right total hip replacement. She underwent left revision acetabular cup surgery and the previously installed cup was replaced with a new Trilogy constrained liner. No further dislocations had occurred at 36-month follow-up. She recovered completely and is now able to engage in daily physical activities.
