Abstract:
Simultaneous bilateral quadriceps tendon ruptures are a rare occurrence commonly associated with a traumatic event or systemic disease. A 31-year-old man presented with simultaneous bilateral quadriceps tendon ruptures with associated hyperparathyroidism secondary to parathyroid carcinoma. The injury occurred after the patient attempted to lift a small wooden log from the ground. We discussed the multidisciplinary management of this patient resulting in bilateral quadriceps tendon repairs, tumor resection, and oncological and endocrinological restoration. Clinical follow-up is reported at 15 years after surgery. Parathyroid carcinoma is an extremely rare cancer and rarely the cause of hyperparathyroidism. The systemic effects of the tumor eventually lead to the rupturing of both quadriceps tendons. Orthopaedic physicians must remain vigilant in identifying the root cause of injuries that are atypical in nature.
