A novel technique using a distally based extensor carpi ulnaris tendon strip combined with ulnar shortening osteotomy has been found to effectively restore distal radioulnar stability in patients with irreparable degenerative triangular fibrocartilage complex injuries due to ulnar impaction syndrome.
Treatment of ulnar impaction syndrome combined with distal radioulnar joint instability due to irreparable degenerative triangular fibrocartilage complex injuries can be complex. We describe the outcomes of a novel technique for restoring distal radioulnar stability due to ulnar impaction syndrome using a distally based extensor carpi ulnaris tendon strip combined with ulnar shortening osteotomy in 48 patients. Patients were assessed using standardized outcome measurements. The patient-rated wrist/hand evaluation total score improved from 66 (SD 15) at intake to 40 (SD 25) at 3 months, and 28 (SD 23) at 12 months postoperatively (p < 0.001). Wrist extension and flexion improved significantly at 12 months from 53 degrees (SD 11) to 65 degrees (SD 8) (p < 0.001) and from 45 degrees (SD 10) to 56 degrees (SD 12) (p = 0.01), respectively. Adding a distally based longitudinal extensor carpi ulnaris strip to ulnar shortening osteotomy for restoring distal radioulnar joint stability seems to be an effective treatment in patients with irreparable degenerative triangular fibrocartilage complex injuries due to ulnar impaction syndrome.Level of evidence: IV
