Moreover, what motions occur at the subtalar joint?
The joints move in a triaxial plane, which allows for the motions of flexion/extension, inversion/eversion, and adduction/abduction.

Similarly, it is asked, what causes subtalar joint pain?
Most subtalar arthritis is caused by a previous trauma, usually a calcaneal fracture, although certain fractures involving the talar body may also cause subtalar arthritis. Other causes include rheumatoid arthritis, or the abnormal loading of the subtalar joint associated with malalignment of the heel bone (calcaneus).
What bones make up the Talocrural and subtalar joints?
The main bones of the ankle region are the talus (in the foot), and the tibia and fibula (in the leg). The talocrural joint is a synovial hinge joint that connects the distal ends of the tibia and fibula in the lower limb with the proximal end of the talus.
