Intramedullary Stabilization Technique Using Headless Compression Screws for Distal Ulnar Fractures

ABSTRACT

Distal ulnar fractures are commonly accompanied by distal radial fractures, and several treatment options such as plate osteosynthesis and pinning with Kirschner's wires are used. In this study, we present a technique using headless compression screws to achieve bony union of distal ulnar fractures. From November 2016 to November 2018, we treated 11 patients with distal ulnar fractures combined with distal radial fractures with headless compression screws (DePuy Synthes). Patients were instructed to maintain a short-arm splint for less than two weeks after the treatment. The mean time to bony union was 6.5 weeks, mean Quick Disabilities of the Arm, Shoulder, and Hand score was 14.6 points, and mean visual analog scale score was 1.09 points. Full range of motion was possible in all directions after surgery and no specific complications were observed. The suggested technique allows minimal incision and minimally invasive intramedullary fixation and can promote bony union in a simple way without specific complications.
