Ulnar shortening osteotomy.

Abstract

Ulna shortening osteotomy (USO) has been “on the market” since 1941. Use of this technique has been widespread over the past seven decades. The indications are well known. The first question a surgeon faces is at what level to perform the USO: diaphyseal, metaphyseal, or even epiphyseal. There is literature supporting all three. Myriad techniques have been described, including transverse, oblique, or step-cut osteotomies and have included freehand methods, as well as specific ulnar shortening plates. Arthroscopic techniques have recently become quite popular and have added several additional surgical options. The common goal has been to correct the length discrepancy between the radius and the ulna in an attempt to reduce wrist pain and to decrease the incidence of delayed union or nonunion and implant irritation I sincerely hope that you will find this symposium both interesting and useful.
