Nonunion After Using Procedure-Specific Instrumentations for Ulnar Shortening Osteotomy2023Arch Bone Jt Surg.
In this study, the authors compared the rates of non-union in ulna shortening osteotomy, comparing between brands and between transverse and oblique osteotomies. Of the 92 patients in this cohort, 90% had a bone union. The authors found that transverse osteotomy was significantly related to non-union. The authors found differences in union between brands, although no statistical analysis was performed. In the 22 patients who were treated with the Medartis USO system, no non-unions or metal removals were observed.
