Inversion of foot
Inversion of the foot is a movement in which the plantar surface of the foot tilts medially towards the midline of the body, with the lateral border of the foot pointing inferiorly. This movement occurs in the coronal plane between the intertarsal joints, primarily involving the subtalar (talocalcaneal) and transverse tarsal (calcaneocuboid and talonavicular) joints.
The range of motion for inversion of the foot at the subtalar joint ranges from 25° to 30°, whilst it is considerably less at the transverse tarsal joint, ranging from 8° to 10°. Inversion of the foot is primarily produced by the tibialis anterior and tibialis posterior muscles.
