The ankle joint, also called the talo-cural joint, is a synovial hinge joint that allows for uniaxial movement. It is formed by the articulation of the distal ends of the tibia and fibula with the talus bone. The ankle joint is stabilized by strong capsular ligaments and synovial membrane, including the deltoid ligament medially and three lateral ligaments. The ankle joint facilitates the movements of plantar flexion and dorsi flexion through the actions of specific muscle groups in the lower leg. Common injuries to the ankle joint include fractures such as Pott's fractures and dislocations or tears of the lateral ligaments.

- 2. ANKLE JOINT It is also called as talo- cural joint. Type : synovial Variety : hinge variety Axis of movement : uniaxial
- 4. BONES FORMING THE JOINT
- 7. LIGAMENTS OF THE JOINT • CAPSULAR LIGAMENT • SYNOVIAL MEMBRANE • DELTOID OR MEDIAL LIGAMENT • LATERAL LIGAMENTS - ANTERIOR TALO FIBULAR - POSTERIOR TALO FIBULAR - CALCANEO- FIBULAR
- 14. LATERAL LIGAMENT
- 16. MOVEMENTS PRODUCED BY ANKLE JOINT • Plantar flexion • Dorsi flexion
- 17. MUSCLES RESPONSIBLE FOR THESE MOVEMENTS • Dorsi flexion- anterior compartment muscles of leg. - tibialis anterior - extensor hallucis longus - extensor digitorum longus - peroneus tertius
- 18. • Plantar flexion- by posterior compartment muscles of leg - gastronemius - soleus - flexor digitorum longus - flexor hallucis longus - tibialis posterior
