Thoroughpin

Description

Thoroughpin is a minor problem that involves distension of the synovial bursa of the tendons in the hind limb. It appears as a soft, boggy prominence on the outside of the hock at, or below, the joint. It is considered a blemish and doesn't affect the actions or health of the limb.

Symptoms

• Swelling of the synovial bursa of the tendon

Causes

The cause of thoroughpin may be a minor injury or a breakdown of tissues that causes fluids to build up in the bursa.

Treatment

Given the nature of the swelling, treatment is usually not necessary. Some veterinarians may recommend draining the fluid, but this is done mostly for cosmetic reasons. Thoroughpin is a recurring and ongoing problem, but usually does not affect the work schedule of the horse.
