Spontaneous Quadriceps Tendon Rupture Associated With Severe Secondary Hyperparathyroidism in a Patient on Chronic Hemodialysis: A Case Report.

Spontaneous or minimal-trauma ruptures of the quadriceps tendon are an exceptional clinical entity, representing a highly unusual presentation even among patients with underlying metabolic conditions, including uremic patients on chronic hemodialysis. We report the case of a 40-year-old male patient on chronic hemodialysis with severe secondary hyperparathyroidism, who was admitted for a rupture of the left quadriceps tendon following minimal trauma. Treatment consisted of the surgical reconstruction of the extensor apparatus and management of his hyperparathyroidism.
