全髖關節置換術（Total Hip Arthroplasty, THA）後的關節穩定性是護理重點。術後需嚴格執行「髖關節預防脫位守則」（Hip Precautions），核心原則是避免患側髖關節內收、過度屈曲（>90度）及內旋。使用外展枕（abduction pillow）可物理性限制腿部內收，維持假體在正確位置。
Joint stability after total hip arthroplasty (THA) is a nursing priority. Strict adherence to hip precautions is required postoperatively; the core principles are to avoid hip adduction, excessive flexion (>90 degrees), and internal rotation on the affected side. An abduction pillow physically prevents the legs from adducting, helping maintain the prosthesis in correct alignment.
