First Metatarsal Phalangeal Joint Fusion with Lapidus Plate System

The metatarsal opening wedge is a technique designed to correct bunion deformities of the foot. The surgeon begins by performing a release of the soft tissues that contribute to the deformity. A saw blade is used to remove the prominent bump on the inside of the big toe. The saw is then used to make an oblique cut in the base of the first metatarsal. An osteotomy or orthopedic chisel is used to enlarge the cut. A jack is then inserted and the saw cut is further widened until the bunion deformity is corrected. When the toe appears straight, a plate is placed on the side of the bone and the jack is removed. The plate is temporarily held to the bone by a pin. The pin contains a ball or olive on it to help hold the plate in place. A drill and screwdriver are used to screw the plate to the bone. After both screws are tightened down, the wire is removed and a third screw placed. Screws are then placed in the remaining holes in the plate, and a bone graft substitute is placed in the gap.
