Surgical fixation systems, methods, and devices

An anatomical stabilization system comprising:

• an anchor comprising:
• a clamping mechanism for securing the anchor to an anatomical feature and comprising first and second contact surfaces, each having a non-slip feature;
• a lock configurable to prevent release of the clamping mechanism from the anatomical feature;
• at least one bridge receptacle;
• and
• a tracking marker.

A method of tracking anatomical movement, comprising:

• receiving first sensor information corresponding to a first pose, at a first time, of an anchor attached to an anatomical element via a clamp, the anchor comprising a tracking marker;
• receiving second sensor information corresponding to a second pose, at a second time after the first time, of the anchor;
• determining an initial pose of the anatomical element based at least in part on the first sensor information;
• determining an updated pose of the anatomical element based at least in part on the second sensor information;
• and
• comparing the updated pose to the initial pose to identify movement of the anatomical element from the first time to the second time.
