- Using Body Mass Index to Predict Needle Length in Fluoroscopy-Guided Lumbar Punctures
The authors evaluated patients who underwent oblique interlaminar-approach fluoroscopy-guided lumbar punctures and had cross-sectional imaging of the lumbar spine within 1 year of the lumbar puncture to devise a formula for the appropriate needle length based on BMI. They determined the formula to predict the needle length as Skin-Canal Distance (inches) = 0.077 x BMI + 0.88.
