Bone Plate And Tracking Device Using A Bone Plate For Attaching To A Patient's Anatomy

摘要

A plate for attaching to an anatomic structure. The plate comprises a top surface opposite a bottom surface. An opening through the top and bottom surfaces is configured to receive a fastener to attach the plate to the anatomic structure. The plate comprises spikes configured to penetrate the anatomic structure. With the fastener, the spikes prevent rotational movement of the body relative to the anatomic structure. The bottom surface is concave between the spikes and defines a space configured to accommodate portions of the anatomic structure. Bone pad surfaces are configured to prevent further penetration of the spikes into the anatomic structure when in contact the same. A tracking device for a surgical navigational system can comprise a tracking head coupled to the plate with a mounting arm. The plate, when attached to the anatomic structure, prevents movement of the tracking device relative to the anatomic structure.
