简要总结
This study will investigate the accuracy of implant navigation for spinal instrumentation. The tested technique is based on commercially available AR-glasses and a specially developed software component
详细描述
The experimental intervention consists of using the AR-glasses and a specially developed software as a navigation aid in surgery. The surgical technique for the intervention group corresponds to the established standard method. It is identical to the control intervention except for the step where pedicle screws or rod implants are instrumented.
The surgeon wears the hardware component during the entire surgery. He proceeds conventionally up to the point where navigation of pedicle screws and rod implants with is required.
