Each of the bone pillars has oppositely disposed distal and proximal ends and a cylindrical main body section extending between the ends. The distal end of each of the bone pillars includes a self-tapping threaded surface portion for screwing into and through a patient's scalp. The proximal end of each of the bone pillars includes a threaded receptacle for receiving a threaded fastener and a driving surface for engagement by a rotatable member to rotate each of the bone pillars.
