Radiologists increasingly perform lumbar punctures, especially in obese patients, using fluoroscopic guidance. This review details techniques and tips for performing lumbar punctures effectively in challenging cases, particularly for trainees.

Area of Science:

  • Radiology
  • Medical Procedures

Background:

  • Lumbar puncture traditionally performed by internal medicine physicians and neurologists.
  • Increasing prevalence of spine surgery and rising obesity rates necessitate radiologist involvement.
  • Radiologists are now the primary providers of lumbar puncture procedures, often using fluoroscopic guidance.

Purpose of the Study:

  • To describe techniques for performing lumbar puncture in difficult cases, focusing on obese patients.
  • To provide tips and maneuvers to facilitate lumbar puncture with fluoroscopic guidance in obese individuals.
  • To share practical experience for trainees early in their careers.

Main Methods:

  • Review of techniques for lumbar puncture in challenging patient populations.
  • Emphasis on fluoroscopic guidance for obese patients.
