Abstract

Various suture anchors and surgical methods are provided. A two-part suture anchor is provided having a continuously threaded anchor body defining an axial bore and a pin. The pin includes a tip and a plate defining at least two suture receiving openings aligned in a single plane that is perpendicular to the longitudinal axis of the axial bore is disposed in anchor body. Methods of attaching soft tissue to bone are also provided.

Claims

1. A suture anchor, comprising:

an anchor body extending along a longitudinal axis from a proximal end to a distal end thereof, the anchor body defining an interior bore and an exterior channel formed partially into an exterior surface of one side of the anchor body, the interior bore and the exterior channel extending from the proximal end toward the distal end thereof;

a distal tip integrally formed at the distal end of the anchor body; and

a port connecting the interior bore to the exterior channel, the port extending from the interior bore through only the one side of the anchor body defining the exterior channel.

2. The suture anchor of claim 1, wherein the distal tip includes a solid distal tip having a smooth outer surface.

3. The suture anchor of claim 1, wherein the port extends radially from and perpendicular to the interior bore.

4. The suture anchor of claim 1, wherein the exterior channel and the interior bore extend parallel to the longitudinal axis.

5. The suture anchor of claim 1, wherein the interior bore is concentric with an outer diameter of the anchor body.

6. The suture anchor of claim 1, wherein the inner bore is radially offset relative to a central longitudinal axis of the anchor body.

7. The suture anchor of claim 1, further comprising external ribs formed on the exterior surface of the anchor body and interrupted by the exterior channel.
