Subtalar Arthroereisis

Arthroereisis has gained popularity over the years because it eliminates excessive pronation while conserving preoperative inversion and preserves forefoot to rearfoot adaptation to uneven terain. Technically simple, some of the advantages of subtalar arthroereisis are that it is joint sparing and preserves ligaments. In addition, the implant does not interfere with osseous growth and does not compromise future operative intervention if more invasive procedures are required. Arthroereisis, however, can have associated complications along with the need for surgical removal in some patient populations.
