This study aimed to assess the relationship between BMI and fluoroscopy time during lumbar epidural steroid injections (LESIs) performed for lumbosacral radicular pain.Multicenter retrospective cohort study.Three academic, outpatient pain treatment centers.Patients who underwent fluoroscopically guided LESI.Mean and standard deviation (SD) fluoroscopy time were compared between patients with normal (18.5-24.9?kg/m2), overweight (25.0-29.9?kg/m2), and obese (=30.0?kg/m2) BMI. Statistical significance was set at P=0.01 due to multiple comparisons.A total of 2,930 procedure encounters were included, consisting of 598 interlaminar LESIs and 2,332 transforaminal LESIs. Fluoroscopy time was significantly longer in the obese patients compared to normal and overweight patients during interlaminar LESI (P?
