Distal Triceps Tendon Rupture Repair
Background Distal triceps tendon ruptures are rare, accounting for 1% of all tendon injuries. Young male athletes (ie, football and rugby players) and weight lifters are the most frequently affected patient population. Elbow extensor mechanism anatomy may allow for the preservation of some strength despite a complete triceps tendon rupture, which may lead to misdiagnosis and delayed management. Acute complete triceps tendon ruptures and partial triceps tendon tears involving more than 50% of the tendon should be repaired to restore maximum function. Transosseous bone tunnels or suture anchors are the two most common constructs used during acute distal triceps tendon rupture repair. Purpose This video demonstrates a technique for repair of an acute distal triceps tendon rupture via suture anchor fixation. Methods An overview of the pathogenesis, diagnosis, and management of distal triceps tendon injuries is provided. The case presentation of a 17-year-old male rugby player with a complete distal triceps tendon rupture is discussed. Distal triceps tendon rupture repair via single-row suture anchor fixation is demonstrated. Results The procedure was successfully performed, and the triceps tendon footprint was restored. The patient was advanced through an individualized postoperative rehabilitation protocol, with progression of motion in a hinged brace permitted at 2 weeks postoperatively and graduated strengthening exercises permitted at 4 weeks postoperatively. At 6 months postoperatively, the patient had regained full functional capacity and was cleared for full-contact sports activity. The patient has since gone on to play college rugby in Europe. Conclusion Surgical repair of the distal triceps tendon to the footprint of the olecranon tip via single-row suture anchor fixation is a reliable treatment option for patients with a complete distal triceps tendon rupture or patients with a partial triceps tendon tear involving more than 50% of the tendon who have functional limitations. Results suggest patients regain full elbow extension strength and return to their preinjury level of high-demand activity.
