Abstract

A method includes generating, based on patient-specific data, a checkpoint zone of a virtual bone model such that the checkpoint zone corresponds to checkpoint positions compliant with at least one constraint based on the patient-specific data. The method also includes guiding creation or installation of a checkpoint on a physical bone using the checkpoint zone of the virtual bone model, and validating registration of the virtual bone model to the physical bone using the checkpoint.
