Abstract
An orthopedic implant device and system support the fusion of bones in the medial column of the human foot. An exemplary implant uses an improved lag screw and supplemental components, including a washer plate and transverse screws which penetrate transverse through holes in the shaft of the lag screw. Additionally, a surgical procedure is described which may employ such an implant. The improved lag screw may be inserted at the plantar surface of the first metatarsal and support the fusion of, for example, the transverse tarsal joint, the cuneonavicular joint, and the tarsometatarsal joint.
