A bone fixation assembly, comprising:
- a bone fixation plate including a fastener hole and a cavity adjacent to the fastener hole;
- a clip comprising:
- a body positioned at least partially in the cavity;
- and
- a plurality of tabs extending inward from the body, each tab having a convex shape extending inward from the body, wherein the body and the plurality of tabs are positioned below a top surface of the bone fixation plate;
- and
- a fastener comprising:
- a body having screw threads;
- and
- a head having a spherical taper, wherein the spherical taper of the head of the fastener is configured to push outward on the plurality of tabs of the clip when the fastener is inserted into the fastener hole;
- and
- wherein the body of the clip is resiliently flexible to permit displacement of the plurality of tabs to allow passage of the head of the fastener, and a spring tension of the clip in a displaced state biases the clip to return to a neutral position over a top surface of the head of the fastener after the head of the fastener has passed below the plurality of tabs of the clip;
- wherein the bone fixation plate further includes a single notch for each of one or more respective fastener holes located adjacent to the respective fastener hole at a position along a midline of the bone fixation plate;
- and
- wherein the clip further includes a protrusion extending from the body of the clip, the protrusion of the clip positioned within the single notch of the corresponding fastener hole.
