Proximal femoral epiphyseal separation in the dog

Abstract

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.

Slipped capital femoral epiphysis in dogs

“…The overrepresentation of the Labrador could be a reflection of their predisposition to osteochondrosis lesions (Slater and others 1991). Lee (1976) postulated that it may relate to the disproportionately slender skeleton of Labradors in relation to their bodyweight or to their frequent tendency to be relatively obese. However, the body condition scores of the dogs in the series by Lee (1976) were not reported.…”

A technique for repair of femoral capital epiphyseal fractures in the dog

“…Various methods have been described for the surgical treatment of femoral capital epiphyseal fractures (Salter-Harris type 1) in the immature dog (Fig 1). These include the use of multiple Kirschner wires, threaded Steinmann pins, compression screw fixation and femoral head and neck excision arthroplasty (Brinker 1966, Nunamaker 1973 Hulse and others 1974, Lee 1976, Aron and others 1979. It was originally believed that, following repair, these fractures were doomed to fail because of avascular necrosis of the femoral head and neck others 1974, Lee 1976).…”

Total hip replacement for the treatment of atraumatic slipped femoral capital epiphysis in dogs

“…Femoral capital physeal fractures are relatively common injuries in dogs, usually resulting from major trauma (DeCamp and others , Gibson and others ). A subgroup of dogs has been reported in which separation of the capital epiphysis appears to occur in the absence of any significant trauma (Lee , Dupuis and others , Moores and others ). This condition has been described as epiphysiolysis or slipped femoral capital epiphysis (SFCE).…”
