Is metaphyseal ulnar shortening osteotomy superior to diaphyseal ulnar shortening osteotomy in the treatment of ulnar impaction syndrome? A meta-analysis.

Background: Although metaphyseal ulnar shortening osteotomy (MUSO) is safer for the treatment of ulnar impaction syndrome (UIS) than diaphyseal ulnar shortening osteotomy (DUSO), DUSO is widely used for UIS treatment.

Aim: To evaluate the effectiveness of DUSO and MUSO for UIS treatment and determine the factors that should be considered when choosing surgical treatment for UIS.

Methods: Articles comparing the effectiveness of DUSO and MUSO for UIS treatment were systematically retrieved from MEDLINE (Ovid), PubMed, EMBASE, and Cochrane Library.
