The posterior talotibialis ligament (l. Talotibialis Posterior, BNA) is one of the ligaments in the human body that connects the talus bone and the posterior part of the tibia. It plays an important role in maintaining ankle stability and ensuring proper foot movement.
The posterior talotibial ligament is made up of connective tissue that spans the posterior surface of the talus and the anterior surface of the tibia, forming a strong structure between them. This ligament holds the ankle joint in a stable position and provides shock absorption when walking and running. It also helps regulate the force of impact when landing on your feet and prevents ankle sprains.
The tarotibialis posterior ligament is a deep ligamentous structure of the posterior surface of the tibia. The main function of this ligament is to fix and stabilize the head of the talus within the joint.
The structure of the joint allows the head of the talus to lock internally and also allows the talus and tibia to move relative to each other when walking. In order to provide this structure, the talus could not move back and out of the joint. This is why ligaments are needed to stabilize the head of the talus in the joint. Thus, we can say that ligaments play the role of a regulator of movement in the skeleton, providing stability and flexibility during movement and standing. The posterior talotibial ligament connects two bones: the tibia and the talus. Connects the tendon of the muscle (triceps surae), which has the anatomical division of the tibiotalar joint, which consists of the talus joints of two bones. The head of the talus is located on the surface of the tibia, and most of the muscle is associated with the lateral condyle.
We can say that this ligament plays an important role in the human body, since its participation allows the body to fully function, is highly resistant to stress, ensures a stable position of a person in space, and controls a person’s movements while walking or running.
