CASE
We report a case of a fifty-eight-year-old woman who sustained a chronic dislocation of the distal radioulnar joint (DRUJ) with extensive secondary cartilage damage and bone loss. We performed an open reduction to restore normal alignment of the distal part of the radius and the distal part of the ulna while preserving the structures that provide stability to the DRUJ.
CONCLUSION
At eighteen months postoperatively, the patient had regained 60° of pronation and 60° of supination and did not have any pain. We found that even in a chronic injury, a simple anatomic reduction can restore the stability of the DRUJ.
病例
我们报告一例58岁女性患者，其桡尺远侧关节（DRUJ）发生慢性脱位，并伴有广泛的继发性软骨损伤和骨质流失。我们进行了切开复位，以恢复桡骨远端和尺骨远端的正常对线，同时保留为DRUJ提供稳定性的结构。
结论
术后18个月，患者旋前恢复了60°，旋后恢复了60°，且无任何疼痛。我们发现，即使是慢性损伤，简单的解剖复位也能恢复DRUJ的稳定性。
