(May 2009) Hypermobility, also known as double-jointedness, describes joints that stretch further than normal. For example, some hypermobile people can bend their thumbs backwards to their wrists, bend their knee joints backwards, put their leg behind the head or perform other contortionist tricks. It can affect one or more joints throughout the body.
The causes of TMJ dysfunction fall into two categories: tight muscles and damaged joints. Anything that causes the jaw muscles to tighten up can cause TMJ dysfunction, including stress and dental disease. Damage to the TMJ can result from trauma or disease such as arthritis. Less common causes of joint problems include fusion of bones or calcification of ligaments (ankylosis), looseness of the jaw caused by stretched ligaments, and birth abnormalities. Treatment is based on cause.
