The aim of this study was to present a novel pre-planned distal radius sliding rotational osteotomy that can address all deformities in dorsally angulated distal radius malunion through a volar approach using a locking plate. Four consecutive adult women with symptomatic dorsally angulated distal radius malunion were surgically treated with sliding rotational osteotomy. All the patients underwent preoperative Disabilities of the Arm, Shoulder and Hand (DASH) scores, a series of radiography, and a course of physiotherapy. The osteotomy was planned on 2 orthogonal radiographs, and the surgery was performed through a volar approach. A back slab was applied post-operatively for two weeks and changed to a removable splint for further four weeks. Gentle active movements out of splint were permitted at two weeks, and formal physiotherapy at six weeks post-operatively. Radiographs were taken immediately post-operatively, at three months, and with DASH scores at a mean final follow-up of 18 months. On radiographic evaluation, all the deformities were corrected within an acceptable range. The mean increase in radial inclination was 6.5 degrees. The mean gain in radial height was 2.95 mm. The mean improvement in ulnar variance was 4.25 mm. The mean change from dorsal to volar angulation was 23 degrees, and the mean improvement in the DASH score was 45.25 at a mean final follow-up of 16 months. All osteotomies achieved bony union within 3 months postoperatively. None of the patients required metalwork removal, and no complications were observed. Sliding rotational osteotomy appears to be a safe technique to correct deformity and improve function in patients with dorsally angulated, shortened, and radially deviated distal radius malunion.
