The lateral side of the ankle has three supporting ligaments: the anterior talofibular ligament (ATFL), the posterior talofibular ligament (PTFL) and the calcaneofibular ligament(CFL). The three ligaments are together called the Lateral Collateral Ligament Complex.

2022年11月17日 · The PTFL is an intracapsular but extra-synovial ligament that arises from the posterior aspect of the distal fibula and courses posteromedially to insert into the lateral tubercle on the posterior aspect of the talus.

2024年12月22日 · Posterior talofibular ligament (PTFL) injuries are far less common than other lateral collateral ligament injuries of the ankle and almost always occur with other injuries 1. The estimated incidence is ~10% (range 4-20%) on MRI in patients with ankle injuries 1,4,6.

2022年4月20日 · short fibers of PTFL restrict internal and external rotation, talar tilt, and dorsiflexion; long fibres inhibit only external rotation, talar tilt, and dorsiflexion Anatomy

The posterior talofibular ligament is a ligament that connects the fibula to the talus bone. It runs almost horizontally from the malleolar fossa of the lateral malleolus of the fibula to the lateral tubercle on the posterior surface of the talus. [1] .

2022年11月9日 · The posterior talofibular ligament (PTFL) is one of the three ligaments which make up the lateral collateral ligament complex of the ankle. The components of this ligamentous complex are: anterior talofibular ligament; posterior talofibular ligament; calcaneofibular ligament.

2023年8月19日 · The PTFL (Posterior Talofibular Ligament) is a ligament that connects the talus bone of the foot to the fibula bone of the lower leg. It is responsible for stabilizing the ankle joint and preventing excessive outward rotation of the foot.

An injured posterior talofibular ligament (PTFL) is one of the reasons for chronic lateral ankle instability (CLAI). Previous researches have demonstrated that the PTFL thickness (PTFLT) is associated with chronic ligament injuries.

2023年5月12日 · The PTFL is the strongest of the lateral ligaments, and extreme inversion with plantar flexion is required to place the PTFL under stress; as a result, the PTFL is less commonly injured....

In order to properly visualize PTFL, it is necessary to identify the bony structures properly, especially the lateral tubercle of the posterior process of the talus. It should be noted that ligaments, in the majority of cases, form a reinforcement for the joint capsule and as they are placed deeply, they form a tissue layer close to the bone.
