The medial talocalcaneal ligament (lat. ligamentum talocalcaneum mediale) is one of the ligaments of the ankle joint. It connects the medial surfaces of the talus and calcaneus.
This ligament strengthens the medial part of the ankle joint, limiting its mobility in the lateral plane. It prevents excessive extension and abduction of the foot. The ligament is fan-shaped and consists of bundles of collagen fibers.
Damage to the medial talocalcaneal ligament can lead to instability of the ankle joint and the development of flat feet. In this case, pain and swelling may occur in the area of the inner edge of the foot. Diagnosis is based on history, clinical examination and imaging of the joint. Treatment includes immobilization, physical therapy, and strengthening of the lower leg and foot muscles. In severe cases, surgery may be required to restore the integrity of the ligament.
The dance ligament is a very strong, posterior direct commissure between the heel bones of humans (and other animals). Stretches the ends of the talus bones. Stronger than other ligaments of the foot and plays an important role in keeping the talus from deforming. Poor development of this ligament leads to shortening of the latter or turning it inward. And underdevelopment, stretching and partial loss of the remaining ligaments of the foot occur in combination with these deviations.
