Question restatement: Which of the following joints facilitates Inversion and Eversion of the ankle?
Options:
- Tarsometatarsal joints
- Subtalar joint
- Talocrural joint
- Distal tibiofibular joint
- Cuneonavicular joint

Analysis of each option:
Option 1: Tarsometatarsal joints. These joints (between tarsal bones and metatarsals) primarily allow some gliding movements that contribute to midfoot flexibility and arch changes, but they are not the main joints responsible for inversion and eversion at the ankle. Misconception here would be assuming the midfoot joints drive gross subtalar movements.
Option 2: Subtalar joint. This joint is formed between the talus and calcaneus and is classically responsible for inversion and eversion of the foot. Movements here change the sole orientation medially or laterally, which directly corresponds to the inversion/eversion of the ankle-foot complex. This is the primary site for these motions.
Option 3: Talocrural joint. Also known as the ankle hinge, the talocrural joint mainly permits dorsiflexion and plantarflexion. While some combined movements can occur, inversion/eversion are not its primary actions, so this option misrepresents the main function of the joint. A common error is to confuse plantarflexion/dorsiflexion with inversion/eversion.
Option 4: Distal tibiofibular joint. This syndesmosis stabilizes the ankle by anchoring the tibia and fibula, especially during weight-bearing, but does not contribute to inversion or eversion movements. Its role is stability rather than movement at the ankle.
Option 5: Cuneonavicular joint. This is a midfoot joint connecting the navicular and cuneiforms, contributing to midfoot mobility and arch mechanics but not primarily responsible for inversion/eversion at the ankle. A mistaken view would be to attribute gross foot rotation to this plane, which is not its main function.

Putting it together: The movement of inverting or everting the foot is a function predominantly localized to the subtalar joint, with other joints contributing secondary roles in overall foot mechanics but not driving the primary inversion/eversion action. Therefore, inversion and eversion are enabled mainly at the subtalar joint.
