Subtalar arthrodesis is the surgical fusion of bones that form the subtalar joint. The subtalar joint is a complex joint located below the ankle joint and is formed by the union of the heel (calcaneus) and the talus (ankle) bone. The subtalar joint allows side-to-side movement of the foot.
Tarsometatarsal joints are the small joints in the middle foot. Osteoarthritis, rheumatoid arthritis or other conditions may damage these joints. The joints may wear out, collapse, cause severe foot deformity and affect the function of the foot. Tarsometatarsal joint fusion is a surgical procedure that fuses the bones of the middle foot to overcome the painful movement and correct deformities in the tarsometatarsal region.
