We have used open reduction and internal fixation with a T-plate in 31 displaced, intraarticular fractures of the distal radius which were judged irreducible or in which closed reduction failed. The mean follow-up time was 4 (3-7) years. The dorsal angulation, the radial length, the articular step-off and the intraarticular gap between fragments were substantially improved after surgery. 30 patients had excellent or good extraarticular alignment, and only 1 patient had a postoperative intraarticular step-off of 2 mm. The function was excellent or good in 26 patients at follow-up. Complications occurred in 6 patients: 1 compartment syndrome, 1 postoperative wound infection, 2 ruptures of the extensor pollicis longus tendon, and 2 patients had median nerve paresthesias.
