Background The ''terrible triad'' of the elbow is a complex injury that can lead to pain, stiffness, and posttraumatic arthritis if not appropriately treated. The primary goal of surgery for these injuries is to restore stability of the joint sufficient to permit early motion. Although most reports recommend repair and/or replacement of all coronoid and radial head fractures when possible, a recent cadaveric study demonstrated that type II coronoid fractures are stable unless the radial head is removed and not replaced. Questions/purposes The purposes of this study were to determine the (1) range of motion; (2) clinical scores using the Disabilities of the Arm, Shoulder and Hand (DASH) and the Broberg-Morrey questionnaires; and (3) rate of arthritic changes, heterotopic ossification (HO), or elbow instability postoperatively in patients whose terrible triad injuries of the elbow included Reagan-Morrey type I or II coronoid fractures that were treated without fixation. Methods Between April 2008 and December 2010, 14 consecutive patients were treated for acute terrible triad injuries that included two Regan-Morrey type I and 12 Regan-Morrey type II coronoid fractures. Based on the senior author's (DGS) clinical experience that coronoid fractures classified as such do not require fixation to restore intraoperative stability to the posterolaterally dislocated elbow, all injuries were treated by the senior author with a surgical protocol that included radial head repair or prosthetic replacement and repair of the lateral ulnar collateral ligament (LUCL) followed by intraoperative fluoroscopic examination through a range of 20°to 130°of elbow flexion to confirm concentric reduction of the ulnohumeral joint. Using this protocol, intraoperative stability was confirmed in all cases without any attempt at coronoid or anterior capsular repair. Repair of the medial collateral ligament or application of external fixation was not performed in any case. All patients were available for followup at a minimum of 24 months (mean, 41 months; range, 24-56 months). The mean patient age was 52 years (range, 32-58 years). At the followup all patients were evaluated clinically and radiographically by the senior author. Outcome measures included elbow range of motion, forearm rotation, elbow stability, and radiographic evidence of HO or arthritic changes using the Broberg and Morrey scale. Elbow instability was defined as clinical or radiographic evidence of recurrent ulnohumeral dislocation or subluxation at final followup. Clinical outcomes were assessed with the patient-reported DASH questionnaire and the physician-administered Broberg-Morrey elbow rating system. Results The mean arc of ulnohumeral motion at final followup was 123°(range, 75°-140°) and mean forearm Each author certifies that he or she, or a member of his or her immediate family, has no funding or commercial associations (eg, consultancies, stock ownership, equity interest, patent/licensing arrangements, etc) that might pose a conflict of interest in connectio...

Computed tomography is useful for preoperative planning and postreduction assessment for intra-articular pediatric ankle fractures. Nondisplaced pediatric ankle fractures can be effectively managed with cast immobilization and close radiographic follow-up evaluation. Physeal ankle injuries in younger children with considerable growth remaining should be followed closely for at least one year after injury as growth arrest may result in substantial angular deformity. Open reduction and internal fixation should be strongly considered when an articular step-off of <2 mm cannot be maintained by closed means for Salter-Harris type-III and IV and transitional ankle fractures.

The anterior protuberance of the radial tuberosity functions as a supination cam; therefore, consideration should be given to preserve its topographical anatomy during a distal biceps repair.
