Abstract
The present invention relates to a bone plate designed to secure locking screws inserted into the plate at various angles. The interior wall surface of the plate apertures include a series of protruding threaded ridges interspaced by relief notches. The threaded ridges and intermediate relief notches of the bone plate in combination with the threaded ridges and intermediate relief notches of the locking screw head allow the locking screw to bypass or 'jump' threads of the bone plate. Thus, the locking screw can be inserted into the bone plate at a first angle and part-way through its advancement along the threads of the bone plate that angle can be changed. The second angle can either be greater than the first with respect to an orientation perpendicular to a longitudinal axis of the bone plate, or less than. This gives the physician a great amount of flexibility during a surgical procedure.
