Although tuberosity calcaneal fracture is rarely found, we report here a neglected avulsion (so-called "beak") fracture of the tuberosity. The etiology of this fracture is presumed to be, in this old female, diabetic (diabetes mellitus) with accompanying osteoporosis. As it was neglected and long-standing, the Achilles tendon lengthening was required on the surgical intervention.
