Fluid-filled swellings around the hock are not uncommon. Some may be innocuous, but others represent a potentially significant injury that requires investigation and treatment.
It can be difficult for even the trained eye to discern whether a particular lump is worth worrying about, but it may be useful to ask yourself the following:
is it a new swelling?
has lameness developed alongside its appearance?
is it warm, or painful to touch?
is it large or tense?
If the answer to any point is yes, it would be prudent to consult your vet. Conversely, if it has been there as long as you can remember and doesn’t appear to be causing a problem, it may be sufficient to monitor the swelling but otherwise leave it alone unless changes occur.
A COMPLEX STRUCTURE
WHY do swellings arise?
The hock is complex, comprising at least six different bones, four major joints, various supporting ligaments and a number of tendons. As the muscles above the hock contract, they pull on the tendons and cause the leg to flex and extend.
To ensure a smooth, gliding action, the tendons are bathed in synovial fluid – a thick, lubricating substance found in capsules called tendon sheaths and bursae. The difference between these is purely anatomical: sheaths encircle one or more tendons, whereas bursae are interposed between two surfaces, such as tendon and bone or cartilage.
The swelling of a joint, tendon sheath or bursa occurs as a response to inflammation – spaces open up in the synovial membrane (the tissue lining the capsule), allowing more cells, protein and fluid to enter and causing visible swelling. This inflammation of the synovial membrane (known as synovitis) is a sign of an underlying problem, rather than being the problem itself.
