Navigated Spinal Fusion in Miami
What Is Navigated Spinal Fusion?
Spinal fusion joins two or more vertebrae to stabilize part of the spine. Surgical navigation is an intraoperative guidance system that creates a three-dimensional reference for the patient’s anatomy and helps the surgeon plan and monitor the position of instruments and implants.
Navigation is a tool used during an operation rather than a separate type of fusion. The underlying procedure may involve decompression, placement of screws and rods, insertion of an interbody implant, bone grafting, or correction of spinal alignment.
How Is Navigated Fusion Performed?
After the patient is positioned, imaging is obtained or previously acquired imaging is registered to the patient’s anatomy. The navigation system tracks specialized instruments in relation to a three-dimensional representation of the spine.
The surgeon uses this information to assist with orientation, surgical planning, and implant trajectories. The fusion itself is then completed according to the patient’s condition and may include decompression, screws, rods, interbody implants, and bone-graft material. The surgeon remains in control throughout the procedure.
Who May Be a Candidate?
Navigation may be incorporated into fusion procedures performed for spondylolisthesis, instability, spinal deformity, fractures, pseudarthrosis, recurrent stenosis, revision surgery, or selected degenerative conditions. A patient is considered for fusion because of the underlying spinal problem—not simply because navigation is available. Candidacy depends on symptoms, examination, imaging, spinal alignment, bone quality, previous operations, overall health, and response to nonsurgical care.
Potential Benefits
Navigation provides the surgical team with real-time anatomical guidance and may be particularly useful when normal landmarks are difficult to see, anatomy is distorted by deformity, or a previous fusion has altered the spine. It may help the surgeon plan implant trajectories and confirm orientation through smaller exposures in selected cases. The potential benefit depends on the procedure, system, anatomy, and accuracy of registration.
Recovery
Recovery is determined primarily by the fusion procedure rather than by navigation itself. Patients generally begin walking early, follow temporary restrictions, and gradually increase activity. Fusion develops over several months and is assessed with follow-up imaging.
FAQs
Q: Does navigation perform the surgery?
A: No. Navigation supplies anatomical guidance. The surgeon plans and performs every step of the operation.
Q: Does navigation guarantee accurate screw placement?
A: No technology eliminates all risk. Navigation can assist with trajectory planning, but the surgeon must confirm that the system remains accurately registered and use clinical judgment.
Q: Does navigation reduce radiation exposure?
A: Radiation exposure varies according to the imaging system and workflow. Some techniques may reduce repeated fluoroscopy, while others require intraoperative three-dimensional imaging.
Q: Can navigation be used during revision surgery?
A: Yes. Navigation may be helpful when scar tissue, existing implants, deformity, or prior fusion has altered normal anatomy, although its suitability is determined case by case.
