Use of osteochondral bone graft in coronoid fractures.
Results of the treatment of the deficient coronoid and chronic elbow instability have not been reported. The purpose of this study was to analyze the results of structural bone graft for reconstruction of the coronoid process. Structural bone graft was used to reconstruct the coronoid process of 6 patients. All injuries were of the terrible triad: fracture of the coronoid, radial head fracture, and collateral ligament disruption. All cases had persistent posterior subluxation averaging 6 months (range, 1-13 months before reconstruction. Patient charts, surgical records, and radiographs were reviewed. All patients were contacted at a mean of 64 months after treatment to answer a specific set of questions to determine the Mayo Elbow Performance score. In 1 patient, radiographs showed complete resorption of the graft and severe osteoarthritis of the elbow at 54 months after surgery (case 4). The Mayo Elbow Performance score showed 1 excellent, 2 good, 1 fair, and 2 poor results. Structural bone graft may be a useful option for a deficient coronoid process and an unstable elbow, but the outcome is unpredictable.
