What is a tibiophibular joint?

tibiophibular joint is one of two articulations between tibia and fibula, two bones in the lower leg between the knee and ankle. These two bones meet at their highest point just below the tibiofemoral or knee joints and at their bottle point just above the talocral or ankle joint. The upper articulation is known as the superior tibiophibular joint or higher of them, and the lower articulation is known as the lower tibiophibular joint or the lower part of both. Both allow very small movement between the two bones. This allows a very less rotation of the lower leg below the knee, while the tibiofemoral joint allows only the movement of the hinge or bending and extending the knee joint. It is located where the lateral condyle tibia bones, the farthest of the two rounded bony Protrusions at the top of the bone meets with the medial or innermost surface of the Fibul head. These two flattened oval surfaces that joined the joint capsules containing synovial fluid during rotary movementsslightly sliding against each other. This tibiophibular joint is also held together by front and rear or front and rear bonds.

At the lower ends of these two bones is the lower tibiophibular joint, which is not a synovial joint, but syndesmosis. Syndesmosis is a type of articulation in which two neighboring bones are connected by an interosseous membrane rather than synovial capsules. Together with the joints of the symphysis, Syndesmoses are classified as an amfiarrtrous joints in that they allow only slight movement. Most of the movements produced by the ankle are achieved by its synovial talocoral joint, which depends on the ankle, and below the subtalalar joint that rolls the leg in and out. Syndesmosis between tibia and fibula, on the other hand, is more important for holding both bones together.

To help maintain and stabilize the relatively stiff structure of this joint, the lower tibiophibular articulation is held together with fourthe edrum ligaments. The front lower tibiofibular ligament (aitfl) intersects before the bones of tibia and fibules; the rear lower lower tibiofibular ligament (pitfl) and transverse liga connect two bones from behind; And interosseous ligament takes place between neighboring bone surfaces of both bones. The inflexibility of these links ensures that the integrity of the lower tibiofibular joint is protected, but this rigidity also leaves them susceptible to high ankle surgery, relatively common ankle ligament injury.
