The rate of malunion after distal radius fractures is 25% after conservative treatment and 10% after surgery. Their main functional repercussion related to ulno-carpal conflict is loss of wrist motion. We report a retrospective clinical series of minimally invasive osteotomies. The series consisted of 9 cases of minimally invasive osteotomies with volar locking plate fixation. All osteotomies healed. The average pain was 5.3/10 preoperatively and 2.1/10 at last follow-up. The mean Quick DASH was 55.4/100 preoperatively and 24.24/100 at last follow-up. Compared to the opposite side, the average wrist flexion was 84.11%, the average wrist extension was 80.24%, the average pronation was 95.33% and the average supination was 93.9%. With similar results to those of the literature, our short series confirms the feasibility of minimally invasive osteotomy of the distal radius for extra-articular malunion.
