Subtalar Arthritis
Subtalar arthritis results in pain in the hindfoot (just below the ankle) with activity. It is aggravated with walking (especially on uneven ground)
It results in decreased eversion and inversion of the foot (side to side movement of the foot)
The most common cause of subtalar arthritis is previous injury including calcaneal and talus fracture
Dr. Marsh performs his subtalar fusion through a small open approach on the outside of the ankle fixed with 2-3 screws across the joint to promote union
When associated with ankle arthritis requiring fusion Dr. Marsh performs his fusion with a TTC fusion nail.
When associated with deformity correction or adjacent hindfoot arthritis Dr. Marsh performs a double (talonavicular and subtalar) fusion or a triple (talonavicular, calcaneocuboid and subtalar) fusion
