FAQs
Registration is the alignment step that links the patient’s actual spinal anatomy with preoperative or intraoperative images. Once this relationship is established, the system can interpret instrument positions within the same three-dimensional anatomical reference. Accurate registration therefore matters because every displayed trajectory depends on how well the image data correspond to the patient during the procedure.
Real-time instrument tracking lets the display show where a surgical tool is and how its trajectory relates to individual vertebrae and nearby structures. This gives the surgeon continuous spatial information while advancing or positioning an instrument, rather than relying only on direct visualization. The resulting orientation is particularly relevant when the intended path must avoid neural or vascular structures.
Preoperative images support planning before the operation, whereas intraoperative images provide anatomical information obtained during the procedure. A spinal navigation system can use either source for registration and guidance, so the imaging choice can be matched to the surgical workflow. In both cases, the goal is to connect planned or observed anatomy with instrument position in three dimensions.
Three-dimensional guidance is most valuable when spinal anatomy or the operative path makes spatial orientation difficult. By displaying the relationship between tools, vertebrae, and surrounding structures, navigation can help standardize complex operations and support more targeted treatment. Its value is not limited to one procedure: relevant uses include pedicle screw placement, decompression, and minimally invasive spine surgery.
A typical navigation workflow begins with image acquisition or selection, followed by registration of the patient’s anatomy to that image set. The surgeon then uses tracked instruments while viewing their position and trajectory relative to the spine. This sequence links planning, instrument handling, and anatomical orientation, allowing the technology to support execution rather than serving only as a preoperative planning aid.
In pedicle screw placement, navigation provides three-dimensional guidance for relating the planned tool path to the vertebrae. During decompression or minimally invasive spine surgery, the same spatial reference can help clinicians work toward a targeted treatment while remaining aware of nearby neural and vascular structures. The expected benefit is greater procedural precision and support for safer execution.
