摘要： A bone plating system for the internal stabilization of a fractured bone is disclosed. The system includes a bone plate having a plurality of conical plate holes tapering toward a bone contact surface and at least two bone screws for anchoring the bone plate to a bone. The screws have a conical head with a textured or structured lateral outside surface which is greater in hardness than the portion of the bone plate which is proximal to the plate holes. The present system provides positive locking between the screw heads and the plate holes.

摘要： A bone plate includes an upper surface, a bone contacting surface, and at least one hole extending through the upper and bone contacting surfaces. The bone plate defines a longitudinal axis. The at least one hole defines a central axis and is elongated in a direction substantially aligned with the longitudinal axis. The hole may include a threaded portion and a non-threaded portion, and the threaded portion may extend through an angle of between about 190° and about 280° with respect to the central axis.
