Abstract

A bone plate system includes, for example, a bone plate and at least one bone plate hole cap. The bone plate includes a body having a first surface, a bone-engaging surface, and a plurality of through-openings. The bone plate hole cap includes a body having a first surface, a second surface, and a peripheral surface. The bone plate hole cap is securable in at least one of the through-openings in the bone plate. When the bone plate hole cap is secured in the through opening, the second surface of the bone plate hole cap is disposed adjacent to the bone-engaging surface of the bone plate. The bone plate with the bone plate hole cap secured in the through-hole increases the bending strength of a portion of the bone plate across the bone plate hole cap compared to the portion of the bone plate without the bone plate hole cap.
