Syndesmosis

Syndesmosis (pronounced: sin-des-moh-sis) is a type of fibrous joint that allows slight movement and is formed by the interosseous membrane connecting the two bones. The term is derived from the Greek words "syn" meaning "together" and "desmos" meaning "band" or "ligament".

Anatomy

Syndesmosis is found between long bones in the body, such as the tibia and fibula in the lower leg, and the radius and ulna in the forearm. These joints are held together by a fibrous connective tissue known as the interosseous membrane.

Function

The main function of syndesmosis is to provide stability while allowing for some degree of mobility. This type of joint allows for slight movement in response to forces applied to the body, such as during walking or running.
