Spinal Surgery and NDI Technology

Spinal Surgery Challenges

There are numerous spinal conditions that can lead to surgical treatment. Spinal surgery can be performed to eliminate pain, improve mobility, and/or remove diseased tissue. Due to the complexity of the spinal anatomy and the natural movement of these anatomical parts, consistently performing precise and accurate surgery required for optimal patient recovery can be very difficult to achieve.

Product Integration

Integrating either the Polaris® family of optical measurement systems or the Aurora® Electromagnetic Measurement System into an image-guided solution for spinal surgeries can improve the accuracy of these surgeries as well as minimize invasiveness through improved pre-operative CT-based planning. How would integration of NDI systems achieve this? Positioning Polaris markers or Aurora coils on/within tools being used to perform the surgery, as well as on the patient, allow the tools and the patient to be tracked by these measurement systems. Once the Polaris or Aurora system can track these items, they can determine their exact position and orientation in real-time. With the exact position and orientation known, surgeons can align the patient’s anatomy with pre-operative CT images in order to accurately target the problem location, while preserving adjacent healthy spine tissue and other structures.

Benefits of Integration

Both NDI Polaris and Aurora technology offer the following benefits when integrated into computer-assisted solutions for spinal surgery.
