Ankle Joint 3D

  • Description

    • * It is a hinge-type synovial joint between the tibia and fibula superiorly and the trochlea of the talus inferiorly.
    • * It permits dorsiflexion and plantar flexion.                                                                                                                                                                           
  • Articular Capsule

    • * It is a thin fibrous capsule that lies anteriorly and posteriorly, allowing movement.
    • * it is reinforced medially by the medial ligament and laterally by the lateral ligament, which prevents anterior and posterior slipping of the tibia and fibula on the talus.                                                                                                                                                                                                          

Ligaments

  • Medial ligament

    • * It has four parts: the tibionavicular, tibiocalcaneal, anterior tibiotalar, and posterior tibiotalar ligaments.
    • * It extends from the medial malleolus to the navicular bone, calcaneus, and talus.
    • * It prevents over version of the foot and helps maintain the medial longitudinal arch.                                                                                                         
  • Lateral ligament

    • * It consists of the anterior talofibular, posterior talofibular, and calcaneofibular ligaments.
    • * It resists inversion of the foot and may be torn during an ankle sprain.
