Bone spavin is another name for which condition?

• A. Hock Synovitis
• B. Windpuffs
• C. Navicular Disease
• D. Stringhalt

Answer: (A)

Bone spavin describes disease of the horse’s hock (tarsus) due to chronic joint degeneration, specifically osteoarthritis of the distal tarsal joints (mainly the distal intertarsal and tarsometatarsal joints). This produces a characteristic hind-limb lameness and a bony, hard swelling on the inside of the hock. In practice, the inflammatory changes within the hock joint are part of what clinicians refer to when they say hock synovitis, so the term can be used interchangeably in many contexts. That overlap is why this option is the best match among the choices. Windpuffs are soft-tissue swelling around the fetlock, not the hock. Navicular disease affects the hoof’s navicular apparatus, not the hock joints. Stringhalt is a neuromuscular hind-limb condition causing exaggerated flexion.
