Distal radius malunion alters wrist biomechanics, leading to pain, stiffness, and functional impairment. Various corrective osteotomy techniques exist. The aim of this study was to evaluate the functional outcomes of a combined radial closing-wedge osteotomy and ulnar shortening osteotomy in the treatment of distal radius malunions.

We retrospectively reviewed 20 patients who underwent combined radial closing-wedge osteotomy and ulnar shortening osteotomy for symptomatic distal radius malunions. Functional outcomes, grip strength, range of motion, and radiographic parameters were analyzed.

Surgery significantly improved supination (20°–80°), flexion (40°–60°), extension (50°–65°), and grip strength (12 kg–22 kg). Ulnar variance correction was achieved. Complications occurred in four cases, with three requiring revision surgery.

Combined radial closing-wedge osteotomy and ulnar shortening osteotomy effectively restores wrist function while avoiding graft-related complications. This approach provides an alternative to opening-wedge osteotomies for distal radius malunions.
