Surgical plan options for robotic machining
A method of performing surgery on a bone includes providing a robotically controlled bone preparation system and creating at least one hole in the bone with the robotically controlled bone preparation system prior to machining the bone. The bone hole aligns with a hole or a post in a guide for a manual cutting tool. If the robot fails during surgery, or if the surgeon does not wish to complete the procedure with the robot, the guide is attached to the bone after aligning the guide hole with the bone hole. The surgery is completed manually after the guide is attached to the bone, and the robot is not used after the guide is attached to the bone.
1. 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.
2. The method of claim 1 , wherein after the implant is coupled to the bone, the implant is not received within either of the at least two bailout holes.
3. The method of claim 1 , wherein cutting the bone includes removing at least one anatomical landmark of the bone, wherein the at least one anatomical landmark would have been used in determining a position and orientation of the manual cutting guide with respect to the bone.
4. The method of claim 1 , wherein the intended procedure and the contingency procedure are both partial knee resections.
5. The method of claim 1 , wherein the intended procedure is partial knee resection and the contingency procedure is a total knee arthroplasty.
6. The method of claim 5 , wherein the at least two bailout holes includes two anterolateral bailout holes and one distal bailout hole formed in a distal end of a femur.
7. The method of claim 5 , wherein the at least two bailout holes includes two anterior bailout holes and one distal bailout hole formed in a distal end of the femur.
8. The method of claim 1 , wherein the intended procedure and the contingency procedure are both patellofemoral joint procedures.
9. The method of claim 1 , wherein the intended procedure is a patellofemoral joint procedure and the contingency projection is a total knee arthroplasty.
10. The method of claim 1 , wherein the intended procedure and the contingency procedure are both total knee arthroplasties.
11. The method of claim 10 , wherein the at least two bailout holes includes two anterolateral bailout holes and two distal bailout holes formed in a distal end of a femur.
12. The method of claim 10 , wherein the at least two bailout holes includes two anterior bailout holes and two distal bailout holes formed in a distal end of a femur.
13. The method of claim 10 , wherein the at least two bailout holes includes two proximal-anterior bailout holes and two proximal bailout holes formed in a proximal end of a tibia.
14. The method of claim 1 , wherein finishing cutting the bone manually with assistance from the manual cutting guide according to the contingency procedure includes the use of a navigation system.
15. The method of claim 1 , wherein the at least two bailout holes are created using a cutting tool operated by the robotically controlled bone preparation system.
16. The method of claim 1 , wherein the at least two bailout holes are created using a cutting tool operated manually.
