Corrective osteotomy in forearm fracture malunion improves functional outcome in adults.

Malunions of forearm fractures in adults can present with limitation of forearm rotation, or as distal radioulnar joint instability with functional impairment. This contrasts with paediatric patients in whom malunions of similar severities are often better tolerated. We did a retrospective review of six adult patients after corrective forearm osteotomy for symptomatic malunited forearm shaft fractures. The corrective operations were done between 7 and 168 months after initial injury, using oblique or wedge osteotomies. Median follow-up was 22.5 months. The patients recovered well, with statistically significant improvement in forearm rotation and Disabilities of the Arm, Shoulder, and Hand (DASH) scores. No significant complications occurred.
