Abstract

An implantable orthopedic repair device includes an implant body having a rigid tubular shape which defines an inner lumen and an orthogonal suture side hole in communication with the inner lumen. The implantable orthopedic repair device includes a tension assembly that is supported by the inner lumen and suture side hole of the implant body. The tension assembly includes a suture loop which defines a suture tail and a sliding knot that when tensioned contracts at least one bone anchor, independent of the implant body, unidirectionally towards the implant body.

Claims

1. An implantable orthopedic repair device comprising:

an implant body having a rigid tubular shape which defines an inner lumen and an orthogonal suture side hole, wherein the inner lumen runs longitudinally through a major axis of the implant body to form a first open end and second open end of the implant body;

wherein a suture tail of the suture loop extends through a suture side hole of the implant body;

wherein the suture loop is configured to be tensioned via the suture tail;

wherein the suture loop comprises a sliding knot; and

wherein when the suture tail is tensioned, the first bone anchor and the second bone anchor are drawn toward the implant body.

9. An implantable orthopedic repair device comprising:

an implant body having a tubular shape that defines an inner lumen, wherein the inner lumen runs longitudinally through a major axis of the implant body to form a first open end and second open end of the implant body, wherein the implant body is rigid;

a first bone anchor adjacent the first open end of the implant body;

a second bone anchor adjacent the second open end of the implant body; and

a tension assembly positioned at least partially through the inner lumen;
