An Inside Look at Joints

موقع أيام نيوز

The relationship between our horses and their joints can feel scary conjuring up words like arthritis and lameness. Our focus on joint function and integrity including how this plays a role in a healthy hoof mechanism and legs is designed to create a knowledgeable foundation to support your horse for years to come. Hopefully by the end of this article you will have a better understanding of joints most specifically in the legs how they function how to help them last longer preferably for the entire life of your horse how to recognize when there is an issue and how to address that issue in the best way. Put your geek hat on we are diving in! 
When it comes to horses we are looking at three main types of joints 
Synovial joints the most common and most movable making up the majority of the joints in the lower extremities



Fibrous joints immobile joints such as those between the cranial bones and
Cartilaginous joints slightly movable joints occurring for example between the vertebrae.
For this article well focus on synovial joints because they are the most common joint in the lower extremities and the most prone to injury and disease due to how mobile they are. 
A synovial joint is a bit of a wonder. These joints are formed when two bones come into relationship and are designed in six different formations pivot hinge condyloid saddle plane and ballandsocket to create mobility and absorb compression. In order to perform those functions a stabilizing joint capsule is developed by the body made up of a fibrous capsule at each bony end collateral ligaments strong and stabilizing fibrous tissue and at certain joints specifically the stifle cruciate ligaments as well as other stabilizing ligaments and tendons. In the inner layer of the joint there is a synovial membrane lining the sides of the capsule and responsible for secreting hydrating synovial fluid to lubricate nourish and cleanse the joint. The synovial fluid contains highly lubricating hyaluronic acid a component you have probably heard of as it is often used in joint supplementation. Disease in the joint appears to commonly be connected to a depletion of hyaluronic acid leaving the joint more susceptible to breakdown. Flexible hyaline cartilage covers the ends of the bone. Its important to note that there is fluid stored within this cartilage which is distributed over the surface of the cartilage during weightbearing
