RESUMEN

PURPOSE: To determine the efficacy of a transverse ulnar-shortening osteotomy at the metaphysis in combination with osteosynthesis using a low-profile, 2.0-mm, locking compression distal ulna plate for the treatment of ulnocarpal abutment syndrome. METHODS: We enrolled into this prospective case series 6 patients with symptomatic ulnocarpal abutment syndrome without distal radioulnar joint ligamentous instability, who had previously failed conservative treatment. We recorded Quick Disability of Arm, Shoulder, and Hand score; wrist range of motion; and visual analog scale score for pain before and after surgery for statistical comparisons. RESULTS: All parameters improved after the surgery. The Quick Disabilities of the Arm, Shoulder, and Hand improved from a mean of 65 to 17, and the visual analog score improved from a mean of 7 to 2. No hardware removal was required and no complications were reported. CONCLUSIONS: Metaphyseal ulnar-shortening osteotomy provided the functional advantages of a midshaft ulnar-shortening osteotomy with the potential for improved bone healing and the reduced risk for complications. This technique was a useful alternative for treatment of ulnocarpal abutment syndrome, especially in patients with more than 2 mm ulnar positive variance. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
