Abstract:
1. A bone plating system, comprising: a bone plate including at least one hole therethrough between an upper surface and a lower surface of said bone plate to receive an anchor for engaging said bone plate to a bony segment, said bone plate including at least one receptacle adjacent to said first hole; and a retaining element including a distal shank portion engaging said bone plate in said receptacle when rotated in a first rotational direction about a rotational center of said retaining element, said retaining element including a proximal head portion extending about said shank portion, said head portion including a top surface opposite said distal shank portion positioned adjacent said upper surface of said bone plate, wherein when viewed in a direction looking along said rotational center toward said top surface said head portion includes: wherein said retaining element includes a first axis extending through said rotational center and bisecting said relief and a second axis orthogonal to said first axis and orthogonal to said rotational center, wherein said arcuate surface of said camming portion circumferentially tapers on said outer perimeter at least from said second axis to said relief in said first rotational direction so that a radius of said outer perimeter where said camming portion joins said relief is less than said first radius of said first perimeter portion extending from said camming portion.
