Abstract
Methods and devices are disclosed for manipulating alignment of the foot to treat patients with flat feet, posterior tibial tendon dysfunction and metatarsophalangeal joint dysfunction. An enlargeable implant is positioned in or about the sinus tarsi and/or first metatarsal-phalangeal joint of the foot. The implant is insertable by minimally invasive means and enlarged through a catheter or needle. Enlargement of the implant alters the range of motion in the subtalar or first metatarsal-phalangeal joint and changes the alignment of the foot or toe.
