Embodiment Construction

[0071] refer to figure 1 , before performing an osteotomy on the bottom bone, the drill guide 1 enables a bone plate fixation hole to be drilled into the bottom bone at a predetermined position. After the osteotomy has been performed, the bone fixation holes receive corresponding bone anchors that secure a preselected bone plate to the bottom bone segment at a predetermined position that aligns the bone segments at the predetermined position . The bottom bone can be the distal radius, and like this, one plate of the drill guide can be placed over the radial stem and a second plate of the drill guide can be placed over the radial head so that the radial stem and the radial head Appropriate alignment to reduce osteotomy fractures of the distal radius. Obviously, the drill guide can be used to align the bone fixation holes in the bony end of any long bone if desired. The drill guide can be fabricated from any suitable material, such as stainless steel and stainless steel alloy...

Abstract

The invention discloses a drilling guide and its auxiliary device. The drill guide includes: a first bone plate extending along a first medial plane; and a second bone plate extending along a second medial plane. The drill guide also includes a first hinge and a second hinge connected to the first hinge. First and second hinges are disposed between the first and second bone plates. Each of the first and second hinges is releasably lockable.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from US Provisional Patent Application No. 61 / 285755, filed December 11, 2009, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates generally to bone fixation, and more particularly to a drill guide system for post-osteotomy bone plates. Background technique [0004] Unreduced fractures and misjoined fractures may cause a greater loss of anatomical function. For example, in a malarticulated fracture, an unreduced radial head may cause a substantial loss of anatomical function of the forearm. Unreduced and misarticulated, extra-articular fractures of the distal radius can subsequently be treated with planned corrective osteotomy. Correct pre-operative planning of the corrective osteotomy can be obtained from two-dimensional X-ray image data or three-dimensional computed tomography data. One such system for maxillary ...
