Marker for tracking objects in medical procedures

Abstract

Tracking objects in medical procedures. At least one example is a method comprising: retaining a bone marker on a distal end of an installation tool, the bone marker comprising a polyhedron having a fiducial pattern on each of at least three outward facing surfaces of the polyhedron, an externally-threaded screw extending distally from the polyhedron, and a flange proximate to an intersection of the polyhedron and the externally-threaded screw; positioning a distal end of the externally-threaded screw against a bone at a marker location; screwing the externally-threaded screw into the bone by way of the installation tool; and trapping tissue against the bone beneath the flange.

Dependencies are inferred from the claim text.
