What causes bone spavin in horses?

Bone spavin is a bony growth within the lower hock joint of horse or cattle. It is caused by osteoarthritis, and the degree of lameness that results can be serious enough to end a horse’s competitive career.

Why do horses get bone spavin?

It is more commonly seen in younger horses, although it can occur at any age. The increase in fluid can be the result of injury (trauma), degeneration of bone or cartilage in the joint (OCD), or joint infection (septic arthritis).

How do you treat bone spavin in horses?

Treatment of Bone Spavin in Horses

How is bone spavin diagnosed?

What causes hock problems in horses?

While several conditions can affect hock joints, for adult horses (especially performance horses) the problem is often degenerative joint disease (DJD), or arthritis. DJD typically develops in the lower joints of the hock, which come under a lot of stress when your horse works. Conformation can contribute.

What is a spavin test?

Pelvic limb flexion (“spavin testing”) during active lameness evaluation is an accurate and widely used detector of distal tarsitis. A positive response results in increased lameness and hypermetria following 60-90 seconds of pelvic limb flexion prior to trotting.

What is Jack spavin in horses?

Jack spavin is usually a bony growth of variable size. The bony enlargement pushes out against a tendon that lies over the inside hock area (Figure 4). The cause of bony growth cannot be fully explained. When the hock is flexed or bent, pain is produced and as a result the hindlimb is not raised very high.
