Introduction to Global Positioning System

Introduction to Global Positioning System

The Global Positioning System (GPS) revolutionized positioning on Earth, providing precise location data through satellite ranging. The GPS system was developed in 1978 by the U.S. Department of Defense for military use, and it became available for civilian applications in 1983, transforming fields including navigation, fleet management, and time synchronization for telecommunications systems.GPS consists of satellites in medium Earth orbit, about 20,200 kilometers above the surface,...

Area of Science:

Neurosurgery
Orthopedic Surgery
Spinal Surgery

Background:

Degenerative spinal disc disease and spinal stenosis often necessitate surgical intervention.
Traditional open spinal discectomy carries risks of significant tissue trauma, complications, and prolonged recovery.
Minimally invasive spine surgery (MISS) is an evolving trend offering reduced morbidity but presents challenges in visualization and surgical field exposure.

Purpose of the Study:

To introduce and describe the Grid Positioning System (GPS) for endoscopic MISS.
To demonstrate how GPS facilitates precise surgical trajectory for spinal decompression.
To highlight GPS's utility in improving outcomes for degenerative spinal conditions and spinal stenosis.

Main Methods:

Development of a Grid Positioning System (GPS) utilizing 3D geometric triangulation.
Guidance of surgical instruments via fluoroscopy along a precise geometric line toward the target lesion.
Application of the GPS system in endoscopic MISS for spinal decompression.

Main Results:

The GPS system provides a precise trajectory for instrument introduction in MISS.
It enables accurate targeting of disc lesions and spinal stenosis for decompression.
The system aids surgeons, particularly in complex cases like morbid obesity, by enhancing visualization and accuracy.

Conclusions:

The GPS system is a valuable tool for facilitating MISS.
It helps mitigate the risks and complications associated with conventional open spinal surgery.
GPS enhances the safety and efficacy of decompressive spine surgery for degenerative conditions.
