Surgical correction for ulnocarpal abutment syndrome after malunited distal radius fracture remains controversial. We reviewed sixteen patients (7 men, 9 women) who underwent isolated ulnar-shortening osteotomy for ulnar wrist pain as their main complaint. Mean age was 48 years. The range of flexion-extension increased from 81 degrees to 103 degrees, and range of supination-pronation from 120 degrees to 142 degrees after osteotomy. Mean grip strength increased from 49% to 69%. Mayo wrist score was excellent in 2 cases, good in 7 cases, fair in 6 cases, and poor in 1 case. Grip strength was found to correlate with radial inclination and flexion-extension range with the amount of ulna shortening.
桡骨远端骨折畸形愈合后尺腕撞击综合征的手术矫正仍存在争议。我们回顾了16例患者（7例男性，9例女性），他们因尺侧腕部疼痛为主诉接受了单纯尺骨缩短截骨术。平均年龄为48岁。截骨术后，屈伸范围从81度增加到103度，旋前旋后范围从120度增加到142度。平均握力从49%增加到69%。Mayo腕关节评分：优2例，良7例，可6例，差1例。发现握力与桡骨倾斜度、屈伸范围以及尺骨缩短量相关。
