[Bilateral avulsion fracture (apophyseolysis) of the calcaneal tuber in a heifer].

This case report describes the clinical, radiographic, ultrasonographic and histopathological findings of a six-month-old heifer, suffering from bilateral fracture of the calcaneal tuber caused by osteochondrosis. The young cattle was admitted to the clinic for the evaluation of a left hindlimb lameness, having persisted for several weeks. Orthopaedic examination revealed a highly stilted gait with a lameness of the left hind limb, so severe that the heifer was only able to put some weight on the tip of the toe. The calcaneal region on both hindlimbs showed a diffuse swelling, palpation being very painful. The radiological examination revealed a fracture of the calcaneal tuber (apophyseolysis) of both hindlimbs.
