Abstract
Disclosed herein are methods and devices for securing soft tissue to a rigid material such as bone. A bone anchor is described that includes an anchor body with expandable tines and a spreader that expands the tines into bone. Also disclosed is a bone anchor that includes a base and a top such that suture material may be attached to apertures in the anchor top or else compressed between surfaces on the base and top to secure the suture to the anchor. Methods are described that allow use of single bone anchor to secure tissue to bone or also to use more than one bone anchor to provide multiple lengths of suture material to compress a large area of soft tissue against bone.
