Treatment of symptomatic non-unions of the base of the ulnar styloid with plate osteosynthesis

Abstract

The purpose of this prospective case series was to assess the efficacy of plate osteosynthesis using a low profile distal ulna plate for the management of persistently symptomatic non-unions of the base of the ulnar styloid. Six consecutive patients underwent resection of the non-union and plate osteosynthesis with a 2.0 mm distal ulna hook plate. Post-operative measurements of mean pain scores, QuickDASH scores, grip strength, and range of motion parameters showed significant improvements compared with the pre-operative values. No complications were reported at a mean follow-up of 25 months. The present study presents an alternative method for treating symptomatic ulnar styloid non-unions that provides stable fixation with low risk of implant removal. Level of Evidence: Therapeutic IV
