The prevalence of known solitary exostosis is around 1-2 % in the general population. Treatment of an exostosis may consist of resection with or without further treatment for deformity. The distal radioulnar joint (DRUJ) acts as the link between radius and ulna at the wrist and is important in the transmission of load. Its anatomic integrity should be respected in surgical procedures or ulnar-sided wrist pain because of instability, limitation of forearm rotation and potential development of grip weakness may develop. We present a case of reconstruction of the DRUJ with distraction lengthening of the ulna after resection of a large exostosis of the distal radius that had resulted in a malformed and dysplastic ulna. This treatment in a young patient resulted in a stable, functional and congruent distal radioulnar joint.
已知孤立性骨软骨瘤在普通人群中的患病率约为1%-2%。骨软骨瘤的治疗可能包括切除，可伴有或不伴有针对畸形的进一步治疗。桡尺远侧关节（DRUJ）在腕部作为桡骨和尺骨之间的连接，在负荷传递中起重要作用。在外科手术中应尊重其解剖完整性，否则可能会因不稳定、前臂旋转受限以及握力减弱的潜在发展而出现尺侧腕部疼痛。我们报告一例病例，该病例为在切除导致尺骨畸形和发育异常的桡骨远端大型骨软骨瘤后，通过尺骨撑开延长重建桡尺远侧关节。这种治疗方法使一名年轻患者获得了稳定、功能良好且匹配的桡尺远侧关节。
