Proximal femoral epiphyseal separation in the dog



Twenty-two cases of displaced upper femoral epiphysis in the dog have been reviewed with regard to the incidence, aetiology, radiographic and histological changes. The majority of the cases followed a severe traumatic episode but a significant number were associated with relatively trivial injuries. On histological examination necrosis of the epiphysis was common but the majority showed a rapid revascularization unassociated with collapse and deformity. The prevalence of the Labrador Retriever in the cases presented is noted.
