Bone Plate

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 for receiving a bone screw. The at least one hole includes a first portion and a second portion that overlap one another. The first portion defines a substantially circular outer periphery and the second portion defines an elongated outer periphery that is elongated in a direction substantially parallel to the longitudinal axis of the plate. The first portion may have threads configured to engage threads on the head of a bone screw, and the second portion may be configured to cooperate with the head of a different bone screw to provide compression to the fracture.

1. A bone plate, comprising:
a first fixation element receiving hole extending therethrough from an outer surface to a bone facing surface of the plate, the first hole including a first substantially circular segment defining a first segment axis and at least one thread for engaging a head of a fixation element inserted therethrough, the at least one thread extending along a wall of the first segment over an angle of at least 180° with respect to the first segment axis and a second segment open to the first segment, a length of the second segment in a direction parallel to a longitudinal axis of the plate being longer than a diameter of the first segment and longer than a width of the second segment in a direction substantially perpendicular to the longitudinal axis, the width of the second segment being longer than the diameter of the first segment.
