摘要
三角纖維軟骨複合體（triangular fibrocartilage complex, TFCC）是位於尺側腕部的重要結構，其幫助腕部承受衝擊並穩定腕部。造成TFCC損傷的原因主要是急性的傷害或長期的手部施力不當過度使用造成手腕骨頭間的互相擠壓碰撞而累積產生退化性病變。TFCC好發於手腕過度伸張、尺側偏和前臂前旋等動作。工作內容有手重覆扭轉、拉動及高施力動作是高風險作業。TFCC損傷的主要症狀為手腕尺側疼痛、抓握的力量減低，以及在工作或活動上的動作受限。然而其損傷症狀常會讓一線醫護人員忽略重要性並診斷為其他疾病。應從過去病史、職業史及理學檢查等來幫助診斷三角纖維軟骨複合體損傷，以給予病患更適合之照護。增進醫師對職業性三角纖維軟骨複合體損傷的認識，將有助於此類職業病的認定與防治。
