Abstract
Bone anchors, after insertion into bone, are designed to remain in place and provide a platform for holding tissue. A method of ultrasonically embedding bone anchors into bone without pre-drilling an anchor receiving hole into the bone has been developed. Also described is an improved bone anchor embedding method utilizing ultrasonic energy to reduce insertion force, whereby the bone anchor and embedding device can be formed very small, (e.g. on the order of 2 to 5 millimeters in diameter). In an embodiment of the present invention, a method of bone anchor embedding utilizing ultrasonic energy is used to insert a bone anchor into a pre-drilled hole, wherein the hole in the bone may be smaller in diameter than the diameter of the bone anchor.
