Retrograde Screw Fixation Results of Coronoid Fractures in Terrible Triad

Abstract

In this study, we aimed to evaluate the results of coronoid fracture fixation, in terrible triad of elbow injury with retrograde screws. Patients between 2008 and 2012 were reviewed. Six were men and 2 were women. Mean age was 44.5(21-62). Mean follow-up period was 25.25 months (8-50). According to Regan and Morrey classification, 6 of the fractures were Type 3 and 2 were Type 2. All cases were operated with single lateral incision. For coronoid fracture, reduction was maintained from anterior aspect and fixed with posterior percutaneous screws which were single 4.5 mm screw in 3 patients and double 3.5 mm screws in 5 patients. Mini and micro cannulated screws for 4 patients and anatomic radial head plates for 4 patients were used for radial head fractures. All lateral ligament complex repairs were performed with bone tunnel technique. The results of the treatment were evaluated with Mayo elbow performance scoring system. All the fractures were united and mean union time was 4 months (3-6). Mean active elbow flexion –extension range of motion at last visit was 108.2º (70º-130º). Mean Mayo elbow performance score of the patients was 87.5 (70-100). With retrograde screw fixation of coronoid fractures in terrible triad, we achieved a stable fixation.
