Abstract
PURPOSE: Intramedullary fixation is one treatment option for distal radius fractures. Our purpose was to compare the outcomes of intramedullary nailing to those of casting for these injuries. METHODS: From 2006 to 2009, we reviewed 63 adult patients with isolated distal radius fractures. Thirty-one patients had surgical fixation with an intramedullary device (IMN group) within 4 weeks of the injury, and 32 (cast group) had casting as definitive treatment of the fracture. Clinical outcomes (grip strength; Disabilities of the Arm, Shoulder, and Hand scores; active wrist range of motion; and complications) and radiographic indices (radial inclination, radial height, ulnar variance, and tilt) of both groups were analyzed for the 1-, 2-, 4-, 6-, and 12-month follow-up periods. RESULTS: The flexion-extension arc was significantly higher in the IMN group than in the cast group at 2-, 6-, and 12-month follow-up. The IMN group exhibited significantly greater grip strength and lower DASH scores throughout the follow-up period. At final follow-up, all radiographic indices were significantly better in the IMN group than in the cast group. There was no significant difference between the initial reduction to final position in the IMN group, but the cast group showed an increase in ulnar variance and a significant change in dorsal-volar tilt. In addition, the cast group experienced more clinical complications in the delayed period compared to the IMN group. CONCLUSIONS: Intramedullary nail fixation, as compared to casting, results in less functional disability, not only in the early postoperative period but also up to a year after treatment. On the basis of our data, intramedullary fixation should be considered for patients with unstable extra-articular or simple intra-articular distal radius fractures. Copyright Â
