  • Medial subtalar dislocations predominate, accounting for approximately 80% of reported dislocations, and are known as acquired club foot, it happens when the foot is in plantarflexion and the lateral collateral ligaments are under stress when there is forceful inversion applied at the forefoot. (physio-pedia.com)
  • They are surrounded by strong ligaments that make this joint relatively stable. (physio-pedia.com)
  • During this position the neck of the talus will hinge and rotate around the sustentaculum tali as a pivot and this will cause a rupture of the lateral talonavicular joint capsule and ligaments, followed by the subtalar ligaments [12] . (physio-pedia.com)

  • In the cases of hypermobility of the ankle joint, an equally or more amount of strength in surrounding structures (peroneals, gastroc, and higher up the kinetic chain) is necessary to overcome the excessive mobility within a particular joints' mobility, due to the passive structures (connective tissue and ligaments) not providing the stability necessary for proper force absorption and force production.
