Simultaneous Bilateral Rupture of the Triceps Tendon in a Renal Transplant Patient.

The unilateral rupture of the triceps brachii tendon is a rare lesion representing 1% of all tendon injuries. The most common causes are the result of a contraction against resistance (especially weightlifters) and direct trauma. It has also been associated with systemic diseases such as diabetes mellitus, chronic renal failure, secondary hyperparathyroidism, and use of systemic corticosteroids. Simultaneous bilateral rupture of the triceps tendons is less frequent and has been described in association with chronic metabolic disorders, especially in those patients on hemodialysis. This paper presents a case of bilateral triceps tendon rupture of a 36-year-old woman with renal transplantation secondary to chronic renal failure. Early surgical repair was performed using a bone tunnel technique with a nonabsorbable suture. Clinically active extension with 135 degrees of range of motion was achieved.
