Abstract

A surgical device includes a first fastener having a planar profile, a second fastener having a concave surface, and a suture that can be manipulated to change a distance between the first and second fasteners. The second fastener has a curvature that substantially matches the curvature of a top surface of a clavicle bone in a direction perpendicular to a long axis of the clavicle bone. A method of treating an acromioclavicular joint injury includes forming axially aligned passages through a patient's clavicle and coracoid process, passing a fastener having a concave surface through the passages, positioning the concave surface of the fastener against a top surface of the patient's clavicle with a long axis of the fastener extending perpendicular to a long axis of the clavicle, positioning a fastener having a planar profile below the patient's coracoid process, and adjusting a suture that couples the fasteners.

First claim

The invention claimed is:

1. A surgical fastener comprising:
a generally circular body having a convex first surface and a concave second surface such that the body has a bowl-shaped profile, the body having a radius R 1 across the first surface of the body;
a first hole and a second hole defined by the body extending from the first surface to the second surface and configured for passage of a first suture, the first hole and the second hole having a first diameter; and
a third hole and a fourth hole defined by the body extending from the first surface to the second surface and configured for passage of a second suture, the third hole and the fourth hole having a second diameter;
wherein the second diameter is selected to be smaller than the first diameter;
wherein the first hole and the second hole are spaced equidistant from a center of the first surface along a first axis extending across the first surface; and
wherein the third hole and the fourth hole are spaced equidistant from the center of the first surface along a second axis extending across the first surface, the second axis being perpendicular to the first axis.

2. The fastener of claim 1 , wherein the radius R 1 is 7 mm.

3. The fastener of claim 1 , wherein the radius R 1 is selected to accommodate a specific anatomy of a patient.

4. The fastener of claim 1 , wherein the first hole and the second hole are in communication with an interior of a neck portion protruding from the second surface of the body.

5. The fastener of claim 1 , wherein the first hole and the second hole are located closer to a center of the first surface than to a perimeter of the first surface.

6. The fastener of claim 1 , wherein the third hole and the fourth hole are located closer to a perimeter of the first surface than to a center of the first surface.

7. The fastener of claim 1 , wherein the body is comprised of a biocompatible material.

8. The fastener of claim 1 , wherein the body is comprised of titanium.
