Proper shoeing is critical in the management of a horse with bone spavin. There are several conformational defects that contribute to bone spavin. Many horses with bog spavin will not be lame. It is best for a horse with bone spavin to be exercised daily. Initially, signs of bone spavin may include sporadic and vague hindlimb lameness. Scintigraphy (bone scan) can help to differentiate between suspensory origin desmitis and bone spavin. Such a response to a flexion test would support the diagnosis of bone spavin. "Juvenile spavin" is the occurrence of bone spavin in horses less than 3 years old. Synovial distension of the tibiotarsal joint in the horse is known as Bog spavin. Unlike bone spavin, bog spavin does not show any changes to the bone itself. Bog spavin is generally an indication of underlying pathology within the joint. Bog spavin is a physical finding, and does not directly create lameness. Bone spavin is a bony growth within the lower hock joint of horse or cattle.
