Study Notes
- Talocrural joint is the articulation of talus with tibia and malleoli
- Mortise structure must be stable to accept leg-foot forces
- Subtalar joint is under the talus and consists of three articulations
- Pronation and supination occur in non-weight and weight bearing conditions
- Subtalar joint moves as calcaneus moves relative to fixed talus
- Transverse tarsal joint consists of talonavicular and calcaneocuboid joints
- Also known as midtarsal or Chopart's joint
- Talonavicular joint and calcaneocuboid joint are anatomically distinct
- Talocrural joint and subtalar joint are important for foot and ankle movement
- Stability of these joints is crucial for weight-bearing and mobility.
