Ulnar-sided wrist pain is commonly caused by the ulnar impaction syndrome. Ulnar-shortening osteotomy is a surgical treatment that is used to address ulnar impaction syndrome that fails conservative management. Unfortunately, hardware irritation and nonunion are well-known complications of this procedure. This case report details the course of two patients with nonunion after ulnar-shortening osteotomy who were treated with a combination of a nitinol compression staple and neutralization plate. Further investigation is required to determine the long-term outcomes and indications for nitinol-staple fixation for nonunion after ulnar-shortening osteotomy.
