Movement in the ankle joint
The foot can be turned outwards, but there is no explicit designation for this movement. Rather, it is a compound movement. The foot has only two axes of movement.
Bending and stretching is made possible by the upper ankle joint (OSG), whereas pronation and supination are movements of the lower ankle joint (USG). In pronation and supination, the foot is tilted, i.e. the outer or inner edge of the foot is moved towards the ground. An external rotation of the foot is therefore a combined movement of a pronation (inner edge of the foot is moved towards the ground) and a flexion of the ankle joint. The gait pattern of externally rotated feet can be caused by a malposition of the hip.
