Bone plate for treating first tarsal metatarsal lisfranc injuries

Abstract

An apparatus and methods are provided for a bone fusion plate for treating 1st tarsal-metatarsal Lisfranc injuries. The bone fusion plate comprises an elongate member that includes a proximal contact surface for attaching to a medial cuneiform bone and a distal contact surface for attaching to a 1st metatarsal bone. Proximal apertures enable implantation of proximal bone screws into the medial cuneiform bone, and distal apertures enable implantation of distal bone screws into the 1st metatarsal bone. A spacing between the proximal and distal apertures positions the proximal bone screws away from a cross screw for treating a Lisfranc injury. A medial thickness of the bone fusion plate vertically implants the proximal bone screws into the greatest thickness of the medial cuneiform. The bone fusion plate includes a tapered distal tip for sliding under soft tissue, thereby facilitating a minimal incision length during implantation of the bone fusion plate.
