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

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

This is a multicenter retrospective series of 30 cases reporting clinical and radiographic criteria with a minimum 6-month follow-up.

The non-union rate was 3.4%. One case presented a non-union of the osteotomy site. 87% of patients were satisfied or very satisfied with the procedure. Mean VAS pain was 2.7 (standard deviation 2.4). The QuickDash and PRWE averages were 24.7 (standard deviation 19.2) and 28.6 (standard deviation 25.3). Mean Jamar dynamometer strength was 27.4kg (standard deviation 8.9). One patient developed complex regional pain syndrome. Five patients required plate removal for hardware-related discomfort.

The Aptus wrist plate ulna shortening osteotomy provides a standardized approach to the surgical treatment of ulnar impingement syndromes of the carpus. Compared with other series in the literature, this procedure provides a satisfactory consolidation rate and clinical results.

The Aptus wrist plate ulna shortening osteotomy provides good outcomes for the treatment of ulnar carpal impingement syndrome.
