Comparative Analysis of Inpatient Opioid Consumption Between Different Surgical Approaches Following Single Level Lumbar Spinal Fusion Surgery

Abstract

Study Design: Single-center retrospective cohort study Objectives: To evaluate inpatient MME administration associated with different lumbar spinal fusion surgeries Methods: Patients ≥18 years of age with a diagnosis of Grade I or II spondylolisthesis, stenosis, degenerative disc disease or pars defect who underwent one-level Transforaminal Lumbar Interbody Fusion (TLIF) or one-level Anterior Lumbar Interbody Fusion (ALIF) or Lateral Lumbar Interbody Fusion (LLIF) through traditional MIS, anterior-posterior position or single position approaches between L2-S1. Outcome measures included patient demographics, surgical procedure and approach, perioperative clinical characteristics, incidence of ileus and inpatient MME. Statistical analysis included one-way ANOVA with a post-hoc Tukey Test and Kruskal–Wallis Test with post-hoc Mann–Whitney test. MME was calculated as per the Centers for Medicare and Medicaid Services and previous literature. Significance set at P
