Summary
Robotic-assisted spine surgery enhances minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) by enabling precise bone decompression and implant placement. This advanced technique improves accuracy, reduces invasiveness, and offers better patient outcomes in spinal fusion procedures.
Area of Science:
- Spine Surgery
- Robotics
- Minimally Invasive Procedures
Background:
- Robotic-assisted spine surgery improves pedicle screw accuracy, reduces blood loss, and shortens hospital stays.
- Minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) is a key area for robotic innovation.
- Previous robotic applications were limited to screw placement, excluding bone decompression and decortication.
Purpose of the Study:
- To provide a comprehensive guide for robotic-assisted MI-TLIF, including facet decortication and decompression.
- To highlight the advancement of robotic technology for both bone decompression and implant guidance.
- To demonstrate how software planning enhances precision and reduces invasiveness in MI-TLIF.
Main Methods:
- Utilized the Mazor X Stealth Edition Spine Robotic System for preoperative planning and intraoperative guidance.
- Employed a surgical arm with 6 degrees of freedom connected to the patient's anatomy.
- Integrated software for screw trajectory planning, facet decortication, and bone removal via a drill.
Main Results:
- Robotic-assisted bone laminectomy demonstrated precision in cadaveric studies.
- The system enables precise execution of preplanned facet joint decortication and osseous decompression.
- Guidance is provided for screw insertion and robotic bone resection.
Conclusions:
- Robotic-assisted facet decortication and decompression represent a significant advancement in spine surgery.
- This technology enhances precision, reduces morbidity, and shifts bone removal to mechanized techniques.
- Anticipated outcomes include reduced pain, improved function, and successful spinal fusion.
