Summary
This study introduces polyprojective microstereotopography for visualizing spinal canal structures using flexible endoscopes. This technique enabled the first endoscopic surgeries for spinal cord injury and related conditions.
Area of Science:
- Neurosurgery
- Minimally Invasive Procedures
- Spinal Anatomy
Background:
- Accurate visualization of the spinal canal is crucial for diagnosing and treating complex neurological conditions.
- Traditional methods may have limitations in fully assessing the intricate structures within the spinal canal.
Purpose of the Study:
- To present a novel polyprojective microstereotopography technique for detailed visualization of spinal canal structures.
- To demonstrate the feasibility of endoscopic examination and surgical interventions within the spinal canal.
Main Methods:
- Utilized flexiscopes (3.7-3.9 mm diameter) on 20 fresh cadavers to map spinal canal topography.
- Performed subdural and subarachnoid endoscopic examinations via posterior or interradicular approaches.
- Visualized key anatomical structures including the spinal cord, nerve roots, and vertebral artery.
Main Results:
- Successfully mapped polyprojective microstereotopography of the spinal canal from the cerebello-spinal to cauda equina levels.
- Visualized critical neural and vascular structures with high fidelity.
- Undertook initial stereotopographically guided endoscopic surgeries for spinal cord injury, syringomyelia, and intraventricular hemorrhage.
Conclusions:
- Polyprojective microstereotopography with flexiscopes offers a viable method for detailed spinal canal visualization.
- This technique facilitates minimally invasive endoscopic interventions for various spinal pathologies.
- The study outlines over ten potential indications for operative spinal endofiberoscopy.
