We investigated the feasibility of arthroscopically assisted reduction and fixation of small coronoid fractures and the anterior
capsule for treatment of patients with Regan and Morrey Types I and II (O’Driscoll Types I and II) coronoid fractures with
instability of the ulnohumeral joint. Four consecutive patients with this fracture type underwent arthroscopically assisted
treatment and were evaluated at a minimum of 1 year (mean, 76 weeks; range, 58–92 weeks). All patients achieved a functional
range of motion with an average flexion/extension arc of 2.5° to 140° and full pronation and supination. No patient had recurrent
elbow instability. One patient had removal of a prominent suture over the subcutaneous border of the ulna. Arthroscopically
assisted management of coronoid fractures can provide excellent observation, enabling anatomic repair without extensive soft
tissue dissection. Preservation of the soft tissue attachments of small coronoid fragments and repair of the capsule are possible
with this technique.
