Bone plating kit for foot and ankle applications
A bone plate kit may be provided for a foot or ankle orthopedic procedure, such as a lapidus procedure. In some examples, the bone plate kit includes a sterile container that holds multiple unicortical bone plate fasteners and one or more bone plates. For example, the kit may contain two bone plates configured to be used together during a tarsal-metatarsal fusion procedure. Each of the two bone plates may be configured to span different regions of a tarsal-metatarsal joint. The unicortical bone plate fasteners can be used to secure the two bone plates to the first metatarsal and medial cuneiform of a patient undergoing a procedure. In some configurations, one of the bone plates is a helical bone plate while the other bone plate may or may not be a helical bone plate.
