title: Arthroscopic distal metaphyseal ulnar shortening osteotomy for ulnar impaction syndrome: a different technique.
abstract: Ulnar impaction syndrome generally occurs with positive ulnar variance. The solution to the problem is to unload the ulnocarpal joint. Effective surgical options include diaphyseal ulnar shortening osteotomy, open wafer osteotomy, and arthroscopic wafer osteotomy. Recently, Slade and Gillon described an open procedure of ulnar shortening in the osteochondral region of the ulnar head. The procedure minimizes the risk of hemarthrosis and does not require hardware removal, which are problems with other surgical options. This article introduces a new arthroscopic technique of distal metaphyseal ulnar shortening osteotomy for ulnar impaction syndrome. This technique offers the advantages of minimizing surgical injury to the dorsal capsule of the distal radoulnar joint and so protects its stability.
