Abstract
A tissue fixation device for securing soft tissue to bone includes an expandable outer sheath, and an inner screw in threaded cooperation with the sheath. The expandable sheath comprises opposing walls in hinged engagement. When the screw is inserted into in the sheath, the walls pivot outwardly about a distal hinge to compress a tissue graft against the bone hole, and to lock the device therein. An optional cortical button is secured across the bone hole entrance, and tethered to the fixation device to bolster fixation.
