Abstract
A bone fixation system has a bone implant with an implant body. The implant body defines an upper surface, a bone-facing surface spaced from the upper surface along a transverse direction, and at least one aperture defined by an inner wall. A bone fixation element is configured for insertion at least partially through the aperture. The bone fixation element defines a proximal end and a distal end spaced from the proximal end along a central axis. The bone fixation element has a head and a shaft that extends relative to the head toward the distal end. The head defines a first ridge, a second ridge spaced from the first ridge, and a groove disposed between the first and second ridges. The groove can receive at least a portion of the inner wall to couple the bone fixation element to the bone implant.
