Abstract
A method and apparatus are provided for transtendinous implantation of a toggle-type bone anchor. Measured from the top surface of the tendon, the entire bone anchor is inserted to a depth of greater than or equal to 20 mm. during a rotator cuff repair on the humeral head. The anchor is pushed by the same bone punch that formed the initial hole to assure proper depth of placement. Further, the apparatus includes a nub portion that, in use, protrudes into the bone hole formed by the bone punch and maintains registration with the bone hole when the bone punch is retracted. An angled distal end on the anchor initiates toggling during insertion into the bone and at least one proximal projecting fin prevents the anchor from backing out of the bone hole while facilitating further rotation of the anchor when a suture is pulled to complete toggling.
