DEFORMABLE THREADED LOCKING STRUCTURES, AND RELATED SYSTEMS AND METHODS

A bone plate (4) includes a plate (5) body defining an upper surface (18), an opposed bone-facing surface, and a combination hole (90) comprising a locking hole (6) and a compression hole (92) that intersect one another and each extending from the outer surface to the bone-facing surface. The locking hole and the compression hole extend away from each other along a longitudinal axis. The plate body further defines a locking surface (24a) that defines the locking hole, and a second surface (24b) that defines the compression hole. The locking surface further defines a plurality of columns (26) sequentially located about a central axis (22) of the locking hole, a plurality of recesses (28) located, respectively, between at least some of the columns, and plate threads (9) that traverse each of the columns. Crests (56) of the plate threads extend linearly from a first side of each column to a second side of each column.
