Ulnocarpal impaction syndrome causes pain on the ulnar side of the wrist. Various surgical techniques have been described. Ulnar shortening osteotomy is now a standard treatment. However, it is associated with complications such as non-union of the osteotomy site.

The main study objective was to report the rate of radiographic consolidation after ulnar shortening osteotomy with a cutting guide.

This multicenter retrospective study of 30 cases reported clinical and radiographic criteria at a minimum 6 month’s follow-up.

The non-union rate was 3.4%. One case presented non-union of the osteotomy site. 87% of patients were satisfied or very satisfied with the procedure. Mean VAS pain rating was 2.7 ± 2.4. Mean QuickDASH and PRWE scores were 24.7 ± 19.2 and 28.6 ± 25.). Mean strength on Jamar dynamometer was 27.4 ± 8.9 kg. One patient developed complex regional pain syndrome. Five patients required plate removal for hardware-related discomfort.

Ulna shortening osteotomy with the Aptus Wrist plate provides a standardized approach to the surgical treatment of ulnocarpal impaction syndrome. Compared with other series in the literature, the procedure provided satisfactory consolidation and clinical results.
