Case report: Proximal Femoral Physeal Dysplasia in a Cat and a Review of the Literature

Femoral physeal dysplasia is a condition in cats resulting in unilateral or bilateral separation of the femoral head from the femoral neck along an abnormal physis. Physeal dysplasia in cats has not been extensively described in veterinary literature, but a review of published data has revealed that while neither the complete pathogenesis nor the incidence is well known, it is suggested that male gender, neutered status, and obesity are contributing factors. A change in castration age could serve as a preventive measure for feline patients. Radiographs have been demonstrated to be the method of diagnosis of choice and surgical correction is the treatment of choice, with a femoral head and neck ostectomy being the most commonly performed procedure. Further study of the condition would be useful to determine predisposing conditions and possible preventive measures.
