subtalar arthroereisisJoe Segen2016-11-12T20:24:27+00:00
A soft tissue movement-limiting operation*, in which an implant is placed to restrict joint motion–e.g., that seen in flatfoot. The goals of arthroereisis in the ankle are to restrict excessive range of motion–ROM in the subtalar joint, allowing up to 5% range of motion, while preserving joint functionality.
*From Greek, arthr-, joint, –ereisis, propping up
Indications Above age 3, flexible foot type, asymptomatic foot pathology
Complications Cyst formation, silastic breakdown synovitis, device migration, over- or under correction, lateral foot and ankle soft tissue strain.
Note: Advances in prosthetic devices, and variable success rates with surgery designed to limit movement, have made arthrodesis and joint replacement the procedures of choice in many cases of articular instability
