Anatomy[edit | edit source]
Articulating Surfaces[edit | edit source]
Trochlea of Talus
Malleolar Mortis formed by Tibia & Fibula
Lateral & Medial Malleolus
Ligaments & Joint Capsule

Lateral Ligaments of Ankle[edit | edit source]
Reinforce Joint Laterally through three ligaments. These three ligaments provide stability by attaching the lateral malleolus to the bones below the ankle joint. They are responsible for resistance against inversion and internal rotation stress.
Ligament | Description | Proximal Attachment | Distal Attachment | Role |
---|---|---|---|---|
Anterior Talofibular Ligament (ATFL) |
Flat Weak Band that extends Anteriomedially. Most commonly damaged ligament of the ankle. |
Lateral Malleolus | Neck of Talus | Resist Inversion in Planterflexion |
Posterior Talofibular Ligament (PTFL) |
Thick, fairly strong band that runs horizontally medially. Rarely injured except in severe ankle sprains |
Malleolar Fossa of Fibula | Lateral Tubercle of Talus | |
Calcaneofibular Ligament (CFL) |
Round cord that passes posterioinferiorly | Tip of Lateral Malleolus | Lateral Surface of Calcaneus |
Aids Talofibular stability during Dorsiflexion. Prevent Talar tilt into Inversion. |
Medial Ligaments of Ankle[edit | edit source]
Known collectively as teh Deltoid Ligament the Medial Ligaments of the ankle attaches proximally to the Medial Malleolus and fan out to attach distally to the Talus, Calcaneus and Navicular via four adjacent and continuous parts. It reinforces the joint capsule medially. Stabilise’s the ankle joint during eversion of the foot and prevents subluxation of the ankle joint.
Ligaments | Description | Proximal Attachment | Distal Attachment | Role |
---|---|---|---|---|
Anterior Tibiotalar Ligament | Medial Malleolus | Head of Talus |
Reinforces Ankle Joint. Contorl Plantarflexion & Eversion | |
Posterior Tibiotalar Ligament | Medial Malleolus | Talus Posteriorly | Control Dorsiflexion | |
Tibionavicular Ligament | Forms most anterior part of the Deltoid Ligament | Medial Malleolus | Dorsomedial aspect of Navicular | Reinforces Ankle Joint |
Tibiocalcaneal Ligament | Very thin ligament | Medial Malleolus | Sustentaculum Tali | Reinforces Ankle Joint |
