Analysis of anatomical surface topology and surgical guide development based thereon

A computer system including:

• a processing circuit;
• and
• a memory storing program instructions for execution by the processing circuit to perform a method that includes:
• determining surface shape variability of a surface of bony anatomy in a surgical region of interest;
• based on the surface shape variability, generating a digital guide design of a proposed surgical guide for use against the bony anatomy during a surgical procedure, the generating determining placement and surface coverage for the proposed surgical guide and configuring the proposed surgical guide to have a corresponding footprint and guide features configured to interface with selected features of the surface of the bony anatomy;
• rating the proposed surgical guide for use against the bony anatomy during the surgical procedure by performing, using the digital guide design, an automated topology-based stability assessment to produce a performance rating for the proposed surgical guide;
• determining whether the performance rating for the proposed surgical guide satisfies a predefined performance rating threshold;
• and
• performing processing based on whether the proposed surgical guide satisfies the predefined performance rating threshold.
