Cause OC / OCD
A joint is made up of two or more bones that hinge together. On both ends of the bone is a layer of cartilage. Between these two layers of cartilage is a joint gap filled with joint fluid (synovia).
In the embryonic phase, which is the earliest developmental phase of the unborn foal, all the bones of the foal are applied in the form of cartilage. When the foal is born, you hit a lot of cartilage. Even before the foal is born, bone cartilage begins to become bone and this continues after birth. Thus, the cartilage gradually transforms into bone. In order to grow, there is a growth disc at both ends of each bone. This growth disc consists of cartilage and multiplies itself. This cartilage, as in the uterus, is transformed into bone and thus the foal grows.
Cause OCD in horses
At a young age if something is wrong with the metabolism, the growth of the cartilage is disturbed. The cause of OC / OCD in horses is thus a malfunction in the conversion of cartilage to bone. As a result, the bone is irregular at the end and the cartilage exhibits a thickening in some places. OC / OCD usually occurs in horses from 4 months to 2 years old.
Breastbone is fed by the joint fluid, but in the places where a thickening is present, the food can not be well done. This weakens that part of the cartilage and causes cracks. Due to load, pieces of cartilage can then be released. These loose pieces can move through movement in the joint. It depends on the joint position whether these particles cause a lot of damage. In many cases, there are no negative effects, so the horse does not suffer.
The loose bone pieces can cause irritation. At the place where the loose piece of bone comes from, dust releases that produce the production of a lot of thin fluid. The joint looks thick and the lubrication decreases which causes arthrosis at a later stage. At some places the cartilage can completely disappear, and the bone has direct contact with the joint fluid. This results in bone solutions that cause cysts, these are cavity cavities.
On an X-ray, OC / OCD can be recognized quickly in horses. However, it is unlikely to put a one-year horse on the picture because the bone structure is still undergoing changes. It may even be that a young horse grows over the condition. A complete X-ray examination is only useful from the age of 2.5 to 3 years.
