Four patients with dorsal dislocation of the distal radioulnar joint and ulnar styloid malunion had corrective osteotomy of the ulnar styloid. Dislocation of the distal radioulnar joint was reduced in three of four patients. Subluxation persisted in the remaining patient. Wrist function improved in all patients. These results support the contention that a displaced ulnar styloid fracture with distal radioulnar joint dislocation should be reduced and internally fixed. Corrective osteotomy is recommended for malunion of the ulnar styloid associated with dislocation of the distal radioulnar joint.
4例桡尺远侧关节背侧脱位合并尺骨茎突畸形愈合的患者接受了尺骨茎突截骨矫正术。4例患者中有3例桡尺远侧关节脱位得到复位。其余1例患者仍存在半脱位。所有患者的腕关节功能均有改善。这些结果支持以下观点，即伴有桡尺远侧关节脱位的尺骨茎突骨折移位应予以复位并内固定。对于合并桡尺远侧关节脱位的尺骨茎突畸形愈合，建议行截骨矫正术。
