Surgical plan options for robotic machining

A method of implanting an implant on a bone comprising:

• providing a robotically controlled bone preparation system;
• performing registration on the bone including fixing a tracker in a fixed configuration with respect to the bone;
• creating at least two bailout holes in the bone;
• wherein the at least two bailout holes are positioned and dimensioned to receive corresponding posts of a manual cutting guide for use in manually resecting the bone when the manual cutting guide is coupled to the bone via the at least two bailout holes, the at least two bailout holes being created only for use if an operator of the robotically controlled bone preparation system desires to transition from an intended procedure that employs the robotically controlled bone preparation system to a contingency procedure that employs the manual cutting guide;
• after creating the at least two bailout holes, cutting the bone using the robotically controlled bone preparation system without the manual cutting guide coupled to the bone and while the tracker is in the fixed configuration with respect to the bone;
• after cutting the bone using the robotically controlled bone preparation system, checking the accuracy of the registration and confirming that the tracker has been moved from the fixed configuration with respect to the bone;
• after confirming the tracker has been moved from the fixed configuration with respect to the bone, coupling the manual cutting guide to the bone via the at least two bailout holes, and finishing cutting the bone manually with assistance from the manual cutting guide according to the contingency procedure;
• and
• after finishing cutting the bone, coupling the implant to the bone.
