Abstract
Some embodiments described herein provide an improved tendon anchoring device and method for securing a muscle tendon to a bone. In particular, implementations described herein, the devices and methods are useful for anchoring a tendon to a bone in a patient's arm, including for example, anchoring a bicep tendon to bore formed in the targeted bone of the arm.
Claims57
A tendon anchoring device, comprising:
- an elongated body extending between a first end and a second end, the body comprising at least one concave side wall and at least one convex side wall, the concave and convex side walls extending longitudinally between the first and second ends;
- a tool engagement surface at the first end of the body adapted to accommodate a mating surface of an insertion tool;
- a tendon engagement surface at the second end of the body, the tendon engagement surface defining an archway bounded by overhanging portions of the convex side wall;
- a plurality of anchor ribs projecting laterally from the convex side wall and distributed between the first and second ends of the body, each of the anchor ribs engageable with a wall formed along a tunnel of a bone;
- and
- a plurality of support ribs projecting laterally from the concave side wall and distributed between the first and second ends of the body, each of the support ribs engageable with a tendon residing within the archway of the tendon engagement surface, wherein one or more of the plurality of support ribs are longitudinally canted relative to a transverse plane of the body, wherein a first set of the support ribs are canted at a first angle relative to the transverse plane and a second set of the support ribs are canted at a second angle that is different from the first.

A method for coupling a tendon to a bone, the method comprising:
- forming a tunnel in a bone, the tunnel comprising an opening and a wall circumscribing the opening;
- placing a tendon over the opening of the tunnel;
- placing a tendon anchoring device over the opening and at least a portion of the tendon, the anchoring device comprising:
- an elongated body comprising at least one concave side wall and at least one convex side wall extending longitudinally between first and second ends of the body;
- a tool engagement surface at the first end of the body;

- a plurality of anchor ribs projecting laterally from the convex side wall;
- and
- a plurality of support ribs projecting laterally from the concave side wall, wherein one or more of the plurality of the support ribs of the anchoring device are longitudinally canted relative to a transverse plane of the body, wherein a first set of the support ribs are canted at a first angle relative to the transverse plane and a second set of the support ribs are canted at a second angle that is different from the first;
- aligning the tendon engagement surface with the tendon to place the tendon within the archway;
- and
- placing the anchoring device carrying the tendon into the tunnel through the opening, thereby causing the anchor ribs to engage the wall of the tunnel and the support ribs to support the tendon against the wall of the tunnel.
