Working Diagnosis:
The patient was diagnosed with a transient elbow dislocation with associated posterior fracture fragments, a complete triceps tear, and a partial tear of the ulnar collateral ligament.
Treatment:
Due to the complete rupture of the triceps tendon, the patient underwent immediate surgical repair. Intra-operative findings included retracted triceps tear with a 1 x 1 cm bony fragment.
Outcome:
Overall, the patient tolerated the procedure well and progressed through a physician directed rehabilitation program with his athletic trainers. The patient was cleared to return to sports after 6 months and participated in spring practices.
Author's Comments:
Triceps tendon rupture remains a rare injury, but what makes this specific case unique is the unusual nature of elbow dislocation and triceps tendon rupture occurring together. Though the mechanism of injury is common with a forceful eccentric contraction following a fall onto an outstretched hand, the patient does not have any of the well-documented risk factors for a triceps tendon rupture such as end state renal disease, rheumatoid arthritis, systemic lupus erythematosus, diabetes mellitus, Marfan's syndrome, osteogenesis imperfecta, hyperparathyroidism, chronic olecranon bursitis, previous triceps injury, anabolic steroid use, local steroid injection, or fluoroquinolone use. Of note, the terrible triad is a well-documented phenomenon seen after elbow dislocation with a radial head/neck fracture and coronoid fracture. However, there have only been a handful of documented cases that report triceps tendon rupture as a complication of elbow dislocation.
Editor's Comments:
Distal triceps tendon ruptures are rare (50%.
