Abstract:
A method for constructing and using a fastener for reattaching a bone flap to a cranium after a surgical operation, wherein the method comprises:(i) constructing a fastener comprising: (a) a pin constructed of a physiologically compatible metal and comprising an elongated shaft with notches on the shaft; (b) an inner disk constructed of a physiologically compatible metal; and (c) an outer disk constructed of a physiologically compatible metal, wherein the outer disk has a central opening through which the pin can extend; (ii) assembling the pin and inner disk together to form a pin and inner disk assembly such that the inner disk is located at one end of the pin; (iii) mounting the outer disk on the shaft of the pin with the shaft of the pin extending through the central opening of the outer disk; (iv) positioning the fastener such that the inner disk is positioned on the inside of the cranium; (v) moving the outer disk downwardly on the pin toward the bone flap until the outer disk securely engages the outside of the bone flap and the cranium, such that the bone flap is securely held in place between the inner disk and the outer disk; and (vi) trimming off an excess portion of the shaft extending out beyond the outer disk.
