=__What //exactly// is a joint?__= = = The joints of the spine are no different than the joints of the elbow or knee, however there are several differences. Before we continue talking about the spine and its joints, let's clarify exactly what a joint is. A **joint** is a place where two different bones make contact.They allow for mechanical movement and support and can be classified by their function and structure.When a joint is classified by structure its name directly reflects how the bone is connected to another bone. There are three main types of joints: fibrous, cartilaginous, and synovial. The spines of the joint are classified as synovial joints.

Now let's talk about the joints of a spine! What's a joint you ask? Well a joint is basically the place where two bones make contact. The function of a joint is to allow a certain degree of movement for particular area of the body. When it comes to the spine the joints are called //facet joints.// The more scientific name for the facet joint is Zygapopheseal joint; but let's just refer to it as the facet joint. Every vetebra has two facet joints connected to it. One of the joints face upward (called the superior facet) and the other faces downward (called the inferior facet). These facet joints act like hinges; keeping the vertebra linked and connected towards the most posterior part of the spine.



In order to prevent damage to the facet joint, a protective barrier is needed. Therefore, each joint is enclosed in a capsule of connective tissue, providing the proper nourishment the joint needs to function effectively. Also, to prevent friction when the joints are moving along the vertebra, cartilage is coated around the joint allowing the joint to move more smoothly. A joint that has this type protective barrier is called a synovial joint.

These joints are very useful, especially when we are in motion. They allow flexion (bending forward) and extension. They allow the twisting motion as well. However, there is much restriction when it comes to other movements. This is due to the interlocking nature of the vertebra. Just like any other joint in the human body there is always chance for injury. One problem that can occur is known as **facet joint syndrome.** A person with facet joint syndrome often suffers from an annoying stiffness in their back; usually requiring them to turn their entire body in order to look over their shoulder! Most of their pain is felt in the shoulder and neck area. The main cause of facet joint syndrome can derive from problems involving artritis. Also, whiplash and sports injuries are common causes of facet joint syndrome. A person with facet joint syndrome tends to walk around with their back hunched over. They become diagnosed with this disease by a qualifed physician. It can, in most cases, be easily treated with proper medication.
