METHOD OF CONNECTING BODY TISSUE TO A BONE

摘要

An improved method of connecting body tissue to a bone in a body. The method includes utilizing an anchor with a conical leading end, a trailing end, a central longitudinal axis passing through the leading and trailing ends, at least two suture passages extending through the anchor transverse to the central longitudinal axis, and a length. The leading end of the anchor has a maximum dimension transverse to the central longitudinal axis that is less than a maximum dimension of the trailing end transverse to the central longitudinal axis. The anchor includes at least one of the suture passages having a portion of a suture positioned therein. The method includes advancing the anchor to insert the leading end of the anchor first through an aperture in a cortical layer of the bone to place the entire anchor within cancellous tissue of the bone, wherein the length of the anchor is greater than a width of the aperture. The method also includes applying a force to the anchor by pulling on the suture to rotate the anchor within the cancellous tissue of the bone to prevent the anchor from passing back through the aperture in the cortical layer of the bone. The method also includes attaching the suture to the body tissue to be connected to the bone.
