Abstract

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° to 103°, and range of supination-pronation from 120° to 142° 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.
