What is tibiophibular syndesmosis?
tibiophibular syndesmosis is a joint just above the ankle, where two long bones of tibia, tibia and fibula are joined at their lower ends. While there are two tibiophibular joints in the leg, one found out where the bones meet at their upper ends below the knee and one where they meet at the bottom ends above the ankle, only the lower joint as syndesmosis is classified. Syndesmosis is a joint that does not allow bones to move to each other. Instead, a fibrous membrane is held together between two bones called interosseous membrane. In addition, the bonds to the outside of the joint hold both bones together and contribute to the stability of the ankle as a whole.
What is referred to as ankle is in fact a complex of three joints contributing to the movement of ankle: tibiofibular syndesmosis, talocral joint and subtalar connect. The highest is tibiophibular syndesmosis in the lower partEven the shin of bones and below is a talocral joint. It is where the lower end ends of the tibia and fibules meet with talocral joint of the ankle talocral joint. Under the talocral joint between Talus and Kacán or Bone heel is a subtalar joint. While talocral and subtalar joints allow the ankle to bend, extend and roll in and out, syndesmosis acts to stabilize the ankle as a whole.
as well as syndesmosis found between the radius and the bones of the ulna in the arm, tibiophibular syndesmosis is a type of joint called amphartrosis. The joints can be categorized according to their structure or by the amount of movement that allow bones, and amparthritis is a functional classification. This type of joint allows a very small degree of movement between the bone it connects, generally a slight rotation around it. Vsyndesmosis gives the ankle as a whole stability, as it allows some flexibility between the bones at the bottom of the foot to receive different forces without breaking bones.
tibiofibuLara syndesmosis can also be distinguished according to its structure. Unlike the talocral joint, a synovial joint that depends on the ankle from the front back, syndesmosis does not contain cartilage or fluid. Instead, the bones are connected by a leaf of tissue, interosseous membrane. Although it is thin, it consists of strong elastic fibers that hold the bones together and also allow some movement on the joint. In addition, several ligaments hold the tibia and fibular to each other and to the bones of the foot, which further contributes to the structure and stability of tibiofibular syndesmosis: the front lower tibiofibular ligament (Aitfl), back lower tibiofibular ligament (PIT) (PITF) and>/p>
