Title: Device and method for mounting an object on a bone

Abstract: A device for removable attachment to a bone of a living patient, useful as a mounting support for a trackable part of a computerized surgical navigation system and a method for attaching an object removably to a bone of a living patient. A shaft having a self drilling, self-tapping screw tip can be inserted transversely of the bone and securely screwed into the cortex. A screw drives a sharp-edged sleeve along the shaft to engage the near cortex. A stepping mechanism allows incremental angular movement of a portion of an adjustment mechanism and indicates when the sleeve is securely engaged by resisting further tightening.
