Abstract
Apparatus for mounting in a bone of a patient, consisting of a rigid elongated member having an axis of symmetry and a distal section, a proximal section, and an intermediate section connecting the distal and proximal sections. The apparatus has n helical blades, formed in the distal section, distributed symmetrically about the axis, each of the blades having a helix angle greater than zero and less than 45°. A cross-section of the distal section, taken orthogonally to the axis of symmetry, includes n mirror planes containing the axis of symmetry, wherein n is a whole number greater than one, and wherein the blades are configured to penetrate into the bone and engage stably therein. Adapters coupling the apparatus to different types of markers are also described.
