Bone Spavin
Bone spavin is osteoarthiritis of the two lowest portions of the hock joint, the distal inter tarsal joint and tarsometatarsal joint.
Signs of this start as hindlimb lameness or stiffness, but worsen over time, it usually involves both hind limbs. It can be diagnosed through X-rays. You can not correct the bony changes, but you can manage the signs with a variety of treatments. These include bute, joint injection to reduce inflammation, intravenous drug injection to slow the bone remodelling. Remedial farriery and controlled exercise also help. The prognosis depends on how severe the arthritis is.
