Kwon, Park, Park, Choi, Nam, Suh, and Kang: Hypertrophic Delayed Union or Nonunion after Ulnar Shortening Osteotomy

Abstract

Ulnar shortening osteotomy is the most popular surgical technique for ulnar impaction syndrome and has a successful clinical results. However, delayed union and nonunion of the osteotomy site remain the most critical complications and conventionally, plate change and autogenous bone grafting had been performed for the treatment of delayed union and nonunion. The authors present 2 patients who had delayed union and nonunion after ulnar shortening osteotomy using 2.7 mm low profile ulnar shortening osteotomy system and can be treated with only additional mini plating.

Figures and Tables

Nonunion site was fully filled with whitish woven bone in revisional surgery of case 1.

Simple radiographs of case 1 (white arrows: osteotomy site). (A) Simple radiograph before ulnar shortening osteotomy. (B) Osteotomy was not united till 1 year after ulnar shortening osteotomy. (C) Bridging callus was seen at 1 month after additional mini-plating. (D) Progressive ossification was seen at 2 months after additional mini-plating.
