DESCRIPTION:

Flexible flatfoot is a common disorder, anatomically described as excessive pronation during weight bearing due to anterior and medial displacement of the talus. It may be congenital in nature or it may be acquired in adulthood due to posterior tibial tendon dysfunction, which in turn may be caused by trauma, overuse, and inflammatory disorders, among others. Symptoms include dull, aching and throbbing, cramping pain, which in children may be described as growing pains. Additional symptoms include refusal to participate in athletics or walking long distances. Conservative treatments include orthotics or shoe modifications. Surgical approaches for painful flatfoot deformities include tendon transfers, osteotomy, and arthrodesis. Arthroereisis with a variety of implant designs has also been investigated.

Arthroereisis (also referred to as arthrosis) is the limitation of excessive movement across a joint. Subtalar arthroereisis (STA) or extrosseous talotarsal stabilization (EOTTS) is designed to correct excessive talar displacement and calcaneal eversion by reducing pronation across the subtalar joint. It is performed by placing an implant in the sinus tarsi (a canal located between the talus and the calcaneus) and is designed to correct excessive talar displacement and calcaneal eversion.

Several implants have received U.S. Food and Drug Administration (FDA) approval through the 510(k) process including but not limited to: Maxwell-Brancheau Arthroereisis (MBA) Resorb Implant™; HyProCure┬« Subtalar Implant System; and SubFix™ Arthroereisis Implant.

POSITION STATEMENT:

Subtalar arthroereisis is considered experimental or investigational as the data in published medical literature are inadequate to permit scientific conclusions on long-term and net health outcomes.
