Precision Spine Surgery
Real-time 3D tracking that shows your surgeon exactly where every instrument is — improving screw accuracy, reducing radiation, and lowering the chance of needing revision surgery.
When a surgeon places a pedicle screw, they are working in a space roughly 5–7 mm wide — surrounded by nerves, blood vessels, and the spinal cord. Traditional fluoroscopy provides a two-dimensional shadow image taken at intervals; the surgeon interprets this image and uses tactile feedback to confirm position. It works, but it requires repeated radiation exposure and introduces a margin of interpretation at every step.
Intraoperative spinal navigation replaces that indirect feedback loop with continuous, three-dimensional, real-time tracking. A reference array fixed to your spine and an intraoperative CT scan allow the navigation system to display every tracked instrument's position — including depth, angle, and proximity to critical structures — overlaid on a live model of your own anatomy. The surgeon sees exactly where they are, not approximately.
The technology is routinely used here across complex fusion, deformity, revision, and minimally invasive spine procedures — not as a marketing feature, but as a standard component of surgical planning and execution.
Navigation adds value across most instrumented spine procedures, but its benefit is most pronounced in situations where anatomy is complex, landmarks are obscured, or the margin for error is smallest:
You don't interact with the navigation system directly — it operates entirely within the surgical workflow. But its downstream effects on your outcome are real:

What navigation does not change
Robotic spine systems have received considerable marketing attention in recent years. They use the same navigation data as standard intraoperative navigation, with the addition of a robotic arm that mechanically constrains a drill along a pre-planned trajectory. Usage varies significantly among spine surgeons and institutions — some use robotic systems routinely, some in selected cases, and some rely exclusively on navigation guidance.
The current published evidence does not clearly establish that robotic guidance produces superior clinical outcomes compared to experienced navigation-guided surgery. Pedicle screw accuracy rates are comparable between the two approaches when navigation is used with technical proficiency. Navigation remains a well-supported and widely used precision tool for instrumented spine procedures.
Spinal navigation is an intraoperative guidance system that tracks the position of instruments and implants in real time relative to a three-dimensional model of your spine. Before or during surgery, an intraoperative CT scan creates a detailed 3D image. A reference array attached to your spine allows the navigation system to detect any movement and compensate for it. Every tracked instrument then appears on the navigation monitor overlaid on your anatomy, so your surgeon knows exactly where each screw, probe, or retractor is at all times — continuously, not just when a fluoroscopy shot is taken.
No. Navigation is a precision tool, not an autonomous system. Every surgical decision — how to approach your anatomy, how much bone to remove, how to correct a deformity — requires experienced surgical judgment that no technology replaces. Navigation improves the accuracy with which the surgical plan is executed by providing real-time, confirmed spatial information. It raises the ceiling on execution precision; it doesn't replace the surgeon who sets the plan.
Navigation tracks instruments and confirms their position throughout surgery — the surgeon moves freely and navigation provides continuous feedback. Robotic systems use a robotic arm to guide a drill along a pre-planned trajectory. Both rely on the same underlying navigation data; the robot adds mechanical constraint to the drill path. Usage of robotic systems varies among spine surgeons and institutions. The current evidence does not clearly demonstrate that robotic guidance produces superior clinical outcomes compared to experienced navigation-guided surgery. Navigation is a well-established precision tool across a broad range of instrumented spine procedures.
Yes. Traditional fluoroscopy-guided surgery requires repeated X-ray images throughout the procedure to check instrument and implant position. Navigation replaces most of this ongoing fluoroscopy with a single intraoperative CT scan and then provides continuous guidance from that data — substantially reducing both patient and surgical team radiation exposure during the procedure.
Navigation is most valuable in procedures where implant position is critical or anatomy is distorted: pedicle screw placement in fusion surgery, minimally invasive procedures where direct visualization is limited, complex deformity correction, revision surgery where normal landmarks are obscured by hardware or scar tissue, and cervical surgeries near critical neurovascular structures. Simpler decompressions without instrumentation may not require navigation.
Clinical studies consistently show that navigation improves pedicle screw accuracy compared to freehand and fluoroscopy techniques — with mal-positioned screw rates dropping from roughly 10–15% with fluoroscopy to under 2–4% with navigation. More accurate screw placement reduces the risk of nerve injury, the need for revision surgery, and implant-related complications. No technology eliminates risk, but the evidence supporting navigation's accuracy benefit is robust.
Questions About Your Upcoming Surgery?
Your surgeon will determine the appropriate tools and approach for your procedure based on your anatomy, diagnosis, and the complexity of the surgery. A thorough pre-operative consultation is where those decisions are explained.
