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.

This cohort study assesses outcomes in patients who underwent CT-guided aspiration and injection of sacral Tarlov cysts at Johns Hopkins Hospital from 2003–2013. A total of 289 cysts were treated in 213 consecutive patients, with 83% followed for 3–6 years. One year postprocedure, excellent results were obtained in 104 patients (54.2% of patients followed), and good or satisfactory results were obtained in 53 patients (27.6%).
