Methods From November 2005 to October 2009,3 cases of terrible triad of the elbow were treated in our hospital. The radial head fractures were classified in type Ⅲ according to Mason classification. All patients underwent coronoid fixation, collateral ligament and joint capsule repair, medial collateral ligament reconstruction and radial head resection. Postoperatively Kirschner wire and the plaster was applied for elbow stabilization for 3 weeks after operation, in position with elbow flexion in 90 degrees and forearm rotation in neutral, and then removal of Kirschner wire and the plaster. Then physical exercise and rehabilitation program were carried out. Results 3 patients were followed up for more than 1 year with fracture healing. The functional outcome in 3 cases was excellent in 2 and good in 1 according to Broberg and Morrey Elbow Score. Conclusion It is exceptionally important of the reconstruction of collateral ligaments and joint capsule in the treatment of elbow terrible triad associated with radial head comminuted fracture for young patients.
