Fusion occurs when the juncture between the ends of two bones transforms from a mobile joint into a stable bony bridge, immobilizing that part of the hock. The joints in the lower hock naturally have minimal movement, which means their fusion can potentially relieve pain without inhibiting the horse’s stride.
How long does it take for a horse’s hocks to fuse?
Fusion typically occurs between 8-10 months following MIA introduction into the affected joint(s). Once fused, the distal tarsal joints are no longer a source of pain or lameness.
How often should hocks be injected?
According to Snyder, some five- to seven-year-olds need only one injection to arrest the inflammatory process, and they may not need a follow-up injection for years. However, other horses—especially older ones—may benefit from yearly injections or even more frequently.
How long does it take for bone spavin to fuse?
Generally, fusion takes six to nine months to develop and, at most, 65% of treated horses are able to return to some work. An alternative means of fusion is to inject a chemical called sodium moniodoacetate (MIA) into the joints.
How do I know if my horse’s hocks are sore?
Common Signs of Hock Pain
Other general signs include sudden laziness, refusal to be tacked up, refusal to perform moves such as a flying lead change, and trouble engaging in the hind end. The horse may also suddenly display general cranky behavior when it is normally quite calm and content.
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.
How long do hock injections last?
Hock injections can be effective anywhere from 6-12 months. If your hock injections are only lasting 8-10 weeks, your horse may be a candidate for laser arthrodesis (surgical fusion).
How much does it cost to inject a horse’s hocks?
I would guess, based on my personal history of injecting joints, the average cost would be around $250-300 per joint. So, if you have a horse with bilateral hock osteoarthritis, then the cost could be upwards of $500.
Are hock injections safe?
Joint injections can safely localize lameness or medicate a joint, but they might cause complications. Corticosteroid elimination varies depending on the dose used and the number of joints treated. Joint injections can safely localize lameness or medicate a joint, but occasionally they can cause complications, too.
How can I improve my horse’s hocks?
Riding over raised poles (cavaletti) is helpful for developing strength in the horse that has weak stifles or hocks. The slow action of lifting the hind legs up and over the pole will strengthen the Tensor muscle as well as the Long Digital Extensor. Both muscle groups are responsible for the stability of the stifle.
Can you ride a horse with bone spavin?
It is best for a horse with bone spavin to be exercised daily. Preferably, this should be ridden or driven work, as lunging exercise places uneven stress on the joint. Pasture turnout may not be beneficial if the horse does not move much.
What does spavin mean?
: swelling especially : a bony enlargement of the hock of a horse associated with strain.
What does bog spavin describe?
Bog Spavin (also known as “serous tarsitis”) is a term used to describe distention or swelling of the uppermost hock joint (known as the tibiotarsal joint).
How do you treat hock injuries in horses?
For OA in the horse’s hock joint, the usual course of action is the injection of anti-inflammatory drugs, such as corticosteroids, directly into the hock joint (intra-articular injections). Your horse will need to have a couple of days rest afterwards and then slowly ease back into work.
When horses drag their back feet?
If he’s uncomfortable, he may not want to engage his hind end correctly so any lameness or discomfort will contribute to him dragging his feet, especially that associated with the hock, such as bone spavin. Things you have control over could also be the cause of your horse’s toe dragging.
Does my horse need hock injections?
Your horse may need hock injections if you notice changes in the hock, general signs of pain, or signs of localized pain in the hock. The first thing to do is to determine if your horse has a lameness problem and the next is to localize the issue to the hock.
