According to a large survey, 88% of the neuroradiologists prefer performing FGLP with the patient in the prone position, while the remaining 12% preferred making the initial puncture with the patient in the lateral decubitus position (1).
Notably, smaller needles are more readily bent and deformed during FGLP. In fact, needle fracture within the interspinous ligament has been reported with a 27G Quincke needle (64).
