Description[edit | edit source]
The Ankle Joint, also known as the Talocrural Articulation, is a synovial hinge joint connecting the distal ends of the tibia and fibula in the lower limb with the proximal end of the talus. The ankle joint is maintained by the shape of the talus and its tight fit between the tibia and fibula. In the neutral position, there are strong bony constraints. With increasing plantar flexion, the bony constraints are decreased and the ligaments are more susceptible to strain and injury. The articulation between the tibia and the talus bears more weight than that between the smaller fibula and the talus. [1]
[2] | [3] |
Anatomy[edit | edit source]
Articulating Surfaces[edit | edit source]
- Trochlea of Talus
- Malleolar Mortis formed by Tibia & Fibula
- Lateral & Medial Malleolus
Joint Capsule[edit | edit source]
The articular capsule surrounds the joints, and is attached, above, to the borders of the articular surfaces of the tibia and malleoli; and below, to the talus around its upper articular surface. The joint capsule anteriorly is a broad, thin, fibrous layer, posteriorly the fibres are thin and run mainly transversely blending with the transverse ligament and laterally the capsule is thickened, and attaches to the hollow on the medial surface of the lateral malleolus. The synovial membrane extends superiorly between Tibia & Fibula as far as the Interosseous Tibiofibular Ligament.[4]
Ligaments[edit | edit source]
Lateral Ligaments of Ankle[edit | edit source]
Reinforce Joint Laterally through three ligaments. These ligaments stabilize the ankle, and serve as a guide to direct ankle motion by attaching the lateral malleolus to the bones below the ankle joint. They are responsible for resistance against inversion and internal rotation stress. [4]
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 |
Restrain anterior displacement of the talus in respect to the fibula and tibia. Resists Inversion in planterflexion. |
Posterior Talofibular Ligament (PTFL) |
Thick, fairly strong band that runs horizontally medially. This ligament is under greater strain in full dorsiflexion of ankle. Rarely injured because bony stability protects ligaments when ankle in dorsiflexion. |
Malleolar Fossa of Fibula | Lateral Tubercle of Talus |
Forms the back wall of the recipient socket for the talus' trochlea. Resists posterior displacement of the talus. |
Calcaneofibular Ligament (CFL) |
Round cord that passes posterioinferiorly | Tip of Lateral Malleolus | Lateral Surface of Calcaneus |
Aids Talofibular stability during Dorsiflexion. Restrain inversion of the calcaneus with respect to the fibula. Prevent Talar tilt into Inversion. |
Medial Ligaments of Ankle[edit | edit source]
Known collectively as the 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. The deltoid ligament is triangular in shape and consists of a superficial and deep layer which connect the talus to the medial malleolus. It reinforces the joint capsule medially. Stabilise’s the ankle joint during eversion of the foot and prevents subluxation of the ankle joint. [4]
