Abstract

A 7-month-old Pomeranian presented with non-weight bearing lameness on the right pelvic limb. Physical examination revealed pain on extension of the right hip joint, and serum chemistry results showed an increased concentration of creatine kinase. Radiographic findings at admission included a weak radiolucent line on the right femoral head and widening of the right hip joint space, and mild displacement of the right capital femoral epiphysis was additionally identified on day 14. Computed tomography (CT) showed a decreased Hounsfield Unit measurement and a fracture line on the right femoral head. Early stage Legg-Calve-Perthes disease (LCPD) was diagnosed and femoral head and neck ostectomy was performed on the right femur. A fracture fissure and osteophytes at the epiphyseal plate of the femoral head were identified surgically. Necrosis in the femoral metaphysis and epiphysis was observed histologically. This case report describes the radiography, CT images, and surgical and histological findings in a dog with early stage LCPD.
