Abstract
A bone plate has a first and a second surface opposite to the first surface, and a deformable contact surface region. The plate has a through hole defining a through hole axis and an inner surface of the bone plate and extending from the first surface through the bone plate to the second surface. The contact surface may be formed by at least part of the inner surface, wherein the deformable contact region comprises a plurality of cavities at least partially surrounding the through hole and each extending in a height direction of the bone plate. Alternately, the deformable contact region may comprise at least one cavity surrounding the through hole in a circumferential direction of the through hole. Also provided is a bone plate system comprising the bone plate and a fastening member being configured to cooperate with the deformable contact region of the bone plate.
