Evidence from four cohort studies suggests that BMI is not a significant prognostic risk factor for most outcomes measured after spinal fusion. Two studies did report a significant association of increasing BMI with risk of perioperative complications following lumbar fusion. There were no consistent findings across studies with regard to BMI and change in functional outcomes after surgery. Obese patients undergoing spinal fusion appear to achieve similar benefits to nonobese patients.
