Embodiment Construction

[0032]FIGS. 2A, 2B, 3, 4A-4E and 5 show a humeral nail 10. As shown in FIG. 3, this humeral nail is intended to be implanted in the humerus 100, shown in FIG. 1 already described, of a patient to fixate a fracture F at or proximate the greater tuberosity 110 and lesser tuberosity 112 of the proximal humerus. The humeral nail 10 includes a substantially linear shaft 12 having a proximal portion 14 and a distal portion 16. The humeral nail 10 is introduced through the humeral head 106 of the humerus 100 and extends within the humeral shaft 116 such that the distal end 16 of the humeral nail 10 is positioned within the medullary canal of the humeral shaft 116.

[0033]It will be noted that the shown humeral nail 10 is designed to be implanted in the right humerus of a patient. A humeral nail that is to be implanted in the left humerus of a patient will be a mirror-image of the humeral nail depicted in the figures.

[0034]In the preferred embodiment, small incisions are made in the skin at s...

Abstract

A method and apparatus of reattaching a bone fragment to a proximal humerus of a humerus in a shoulder joint. The method includes introducing a distal end of the humeral nail into a medullary canal of the humerus. A first proximal screw is engaged with the bone fragment and a first proximal bore in the proximal end of the humeral nail to move the bone fragment toward the proximal humerus. The humeral nail and the attached bone fragment are rotated relative to the medullary canal of the humerus to position the bone fragment to an anatomically optimal location. The bone fragment is preferably one of a greater or lesser tuberosity of the proximal humerus. The method and apparatus can be used to reattach bone fragments in a variety of other joints.

Description

[0001]This application claims priority to U.S. provisional patent application 61 / 051,320, filed May 7, 2008 herein incorporated by reference.TECHNICAL FIELD[0002]The present invention relates to a method and apparatus for fixation of proximal humeral fractures. In particular, the present invention relates to a humeral nail for reduction and orientation of the tuberosities at a humeral fracture site.BACKGROUND OF THE INVENTION[0003]As illustrated in FIG. 1, the humerus 100 of the upper arm is part of a “ball and socket” joint at the shoulder 102. The proximal humerus 102 includes a large rounded humeral head 106 joined to the humerus shaft 116 by a humeral neck 108 and two eminences, the greater and lesser tuberosities 110, 112.[0004]Proximal humeral fractures are the most common humeral fractures. These are often found in patients who have fallen on their arms, creating an axial load on the humerus 100 that causes a fracture of the humeral head 106. In a two-part fracture, the humer...
