HINGABLE AND FIXABLE BONE PLATE SYSTEM

摘要

A bone plate apparatus for securing a bone or a bone fragment in a proper position with respect to another bone or a bone fragment has a plate with a first portion and a second portion in which the first portion is hingedly connected to the second portion, and a fixing element cooperative with the first and second portions so as to fix an angular orientation of the first portion with respect to the second portion. The fixing element is a screw that is rotatable in the hinge in one direction such that the first portion is freely pivotable with respect to the second portion and rotatable in an opposite direction so as to fix an angular orientation with the first portion with respect to the second portion. Each of the first portion and the second portion has holes formed therein suitable for the receipt of bone screws such that the portions can be affixed against a surface of the bone or the bone fragment.
