a CyclaPlex™ implant device. The device is made up of two screw-type buttons (anchors) and a connecting wire between them. The medial button (on the left end) is inserted into the first metatarsal. The wire protrudes from the lateral button (on the right). b The 2nd metatarsal serves as an anchor. The 1st metatarsal is pulled laterally by pulling the wire protruding from the 2nd metatarsal. The implant device remains in the foot. The arrowheads indicate the direction in which both the wire and the 1st MT are being pulled
