Benefits of technology

[0003]Part of a successful surgery to reconnect tissue to bone requires that sutures firmly secure the tissue to the bone. It is important that the repair have long term stability. The disclosed method, system and device for securing the repair includes an anchor placed within a pre-drilled hole formed in bone and a cannulated screw inserted into the hole after the anchor, and holding same in place, to effectuate a firm and secure connection of tissue to bone, particularly when the quality of the bone does not permit optimal fixation. The method, system and device allows superior screw in fixation with the ease of knotless suture anchor application.

Problems solved by technology

Difficulties arise when the anchor has been inserted and is not flush with the top of the bone mass.
Additionally, the anchor has been known to move or adjust thereby jeopardizing a secure repair.

Embodiment Construction

[0010]FIG. 1a shows the cannulated fastener, such as a cannulated bone screw 10 having a central bore 12 extending the entire length of the screw, allowing the screw to move along a bone anchor inserter rod. The fastener may be made of any suitable material, including bioabsorbable material, and may be a barbed fastener which is driven into a bone hole, rather than screwed. The fastener that is inserted need only have a flattened distal aspect to block the fixation anchor from migrating. In FIG. 1b, an anchor 14 has been inserted within a hole 16 in a bone 18. The anchor has a suture loop 20, either fixed or adjustable in length, passing through tissue 22, such as a rotator cuff, to secure the tissue 22 to the bone 18. The anchor has captured the loop, allowing for fixation without needing to tie a knot. As can be seen, there is a distance between the top of the anchor and the top of the opening in the bone. This distance can be measured by markings 25 along the inserter rod 24 seen...

Abstract

A method, system and device for securing a repair, such as a rotator cuff repair and includes an anchor placed within a hole formed in bone and a cannulated screw inserted into the hole after the anchor has been inserted to effectuate a firm and secure connection of tissue to bone, particularly when the quality of the bone does not permit optimal fixation. The method, system and device allows superior tissue fixation to bone with the ease of knotless suture anchor application.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001]The present application claims the benefit of U.S. Provisional Patent Application Ser. No. 61 / 071,568, filed On May 6, 2008. The subject matter of the provisional patent application is incorporated by reference herewith.BACKGROUND OF THE INVENTION [0002]During surgery, anchors have been used with sutures to reattach tissue to bone. The anchors have been inserted into holes that have been pre-drilled. Difficulties arise when the anchor has been inserted and is not flush with the top of the bone mass. Additionally, the anchor has been known to move or adjust thereby jeopardizing a secure repair.SUMMARY OF THE INVENTION [0003]Part of a successful surgery to reconnect tissue to bone requires that sutures firmly secure the tissue to the bone. It is important that the repair have long term stability. The disclosed method, system and device for securing the repair includes an anchor placed within a pre-drilled hole formed in bone and a cannulate...
