Wrist Disorders
A 55-year-old woman presents 6 months after non-operative treatment of a distal radius fracture. She has persistent wrist pain, weak grip, and limited forearm rotation. Examination reveals dorsal prominence of the distal radius and painful crepitus at the DRUJ with forearm rotation. Radiographs show the radius has healed with 25 degrees of dorsal angulation, 5mm of radial shortening, and loss of radial inclination. Ulnar variance is +6mm. Regarding distal radius malunion:
