Amount of ulnar resection is a predictive factor for ulnar instability problems after the Sauvé-Kapandji procedure: A retrospective study of 44 patients followed for 1–13 years

Abstract

If the shortening of the proximal stump is less than 35 mm, a reliable improvement in motion and a high patient satisfaction can be expected. The risk of a painful ulnar instability is related to the amount of resection, and can be reduced by creating a long upper ulnar stump.
