Clinical-pathological findings in two cats with Slipped Capital Femoral Epiphysis

In cats, most of the times, hind limb lameness with separation of the femoral capital epiphysis is due to traumatic injury. In veterinary medicine, it has been described as feline physeal dysplasia characterized by an atraumatic lesion of the physeal cartilage, and it has been also reported in human medicine as slipped capital femoral epiphysis. This article describes two cases of physeal dysplasia in two cats. Both cats were presented with an acute onset and severe hind limb lameness. Radiographic examination showed a radiolucent line crossing the metaphysis and a capital physeal incongruity with signs of bone resorption at the femoral neck. No other clinical and laboratory anomalies were seen at that time. Excision of the femoral head was performed in both cats. Bone samples were fixed in formalin and processed for a standard histological and histochemical evaluation. The definitive diagnoses were in both cases of physeal dysplasia with slipped capital femoral epiphysis
