Your spine surgery may involve the placement of screws or other implants in the spine. Traditionally, these are placed freehand or with X-ray guidance. Despite careful technique, there is a chance of implants being placed in an inaccurate position – posing a risk to the spinal cord, spinal nerves or other structures.
Spinal navigation uses modern computer technology to increase the accuracy of placement – increasing safety. The O-arm/Stealth system is one of 2 main systems that Dr Ball can use for your surgery. The choice of system depends primarily on the type of surgery required. Both have demonstrated high rates of accuracy.
O-arm™ with Stealth™ (Medtronic™ )
The O-arm™ is an intra-operative ‘CT scanner’ which is used to take a scan of the patients spine. This scan provides a ‘map’ of the patients spine and is transferred to the Stealth™ navigation system.
The instruments used in the surgery are visible to the Stealth™ Station which shows the location and direction of the instruments on the 3D scan to guide the surgery.
