9 month old male Labrador Retriever with forelimb lameness

Discussion

Panosteitis is a disease of growing dogs in which inflammation of the medullary tissues leads to scarring and sclerosis. German Shepherd dogs are predisposed. The disorder can affect multiple long bones at different times, resulting in shifting lameness. It is rare to see panosteitis in dogs over two years of age. It resolves with symptomatic treatment. The left front limb was more mildly affected in this dog, as were both femurs.
