Beware! The volar ulnar fragment in a comminuted Bartons fracture

Abstract

The purpose of this study is to highlight a cohort of patients with a comminuted volar shearing type of distal radius fractures (AO B3.3) with the volar ulnar fragment that is prone to re-displace, resulting in volar subluxation of the radiocarpal joint. We report our experience with two such patients with re-displacement of the fragment and joint requiring repeat surgery; one of whom required a third procedure to stabilize that fragment. Three subsequent patients were successfully treated with one surgery when particular attention was paid to stabilize the volar ulnar fragment. This highlights the importance of stabilizing this fragment at the primary procedure.
