We report a case of intra-articular loose body in the mid-carpal joint following the fracture of the distal radius. The patient fell from a height of 5 ft. The radiographs and computed tomography scan showed a bony fragment in the midcarpal joint. It was associated with dorsal scapholunate ligament tear. The intra-articular bony fragment originated from the fracture distal radius. The possible relationship of the intrusion of the bony fragment and SL ligament injury is discussed. 我們報告一宗橈骨遠端骨折伴隨有腕中關節游離體的個案。患者從5 呎高處墮下。X光和電腦掃瞄檢查顯示腕中關節中有骨碎片及伴隨的背側舟月韌帶撕裂。關節內的骨碎片起源於橈骨遠端骨折處。我們就骨碎片的入侵與舟月骨韌帶損傷的可能關係進行了討論。
