Triceps Tendon Rupture – A Novel Repair of an Uncommon Injury

INTRODUCTION: Triceps tendon rupture is a rare injury accounting for <1% of all tendon injuries with varying repair techniques described. We present this novel repair to supplement available literature and help optimize the clinical outcomes for affected patients. We report this technique because it is unique in that we augmented our surgical fixation with a subtle variation in the described technique by repairing the deep portion of the triceps tendon as a separate step, maximizing the recreation of the anatomic footprint of the triceps. CASE REPORT: The patient is a 70-year-old Caucasian male presenting with pain, swelling, and ecchymosis around the elbow after the episode of injury. He also complained of a painful popping sensation whenever he ranged the elbow and an inability to extend, with pain and weakness any time he attempted elbow extension. Radiographs reviewed at his initial visit revealed a small osseous fragment approximately 5 cm proximal to the olecranon tip. Subsequent MR imaging confirmed our suspicion, showing a complete tear of the triceps tendon with hematoma at its insertion site and tendon retraction approximately 3 cm proximally. With the diagnosis of triceps tendon rupture conformed, we took the patient for primary tendon repair using suture with bone bridge and suture anchor, using elements from described techniques. Our technique was unique in that we performed repair of the deep and superficial triceps attachments as separate steps, in an endeavor to improve the anatomic reconstruction of the footprint and biomechanical strength. CONCLUSIONS: We combined findings from our review of the available literature with novel surgical techniques and suture design to maximize the patient outcome and minimize complications. The patient went on to have a very satisfactory functional recovery. We hope that this case report will complement the evidence-based care of these patients by orthopedic surgeons and lead to the best results possible.
