title: Spontaneous and simultaneous bilateral rupture of the quadriceps tendon in a patient with osteogenesis imperfecta: a case report.
abstract: Bilateral rupture of the quadriceps tendon is an uncommon and serious injury that usually occurs in middle aged to elderly patients. It is frequently associated with chronic metabolic disorders like diabetes, hyperparathyroidism, gout, chronic renal failure or the chronic use of steroids. We report a case of spontaneous bilateral rupture of the quadriceps tendon in a patient with osteogenesis imperfecta.
