Increased acute postoperative wound problems following spinal fusion in overweight patients with adolescent idiopathic scoliosis

This study assessed the rate of adverse wound events in individuals with adolescent idiopathic scoliosis who underwent a posterior spinal fusion and sought to determine if obesity was related to the rate of adverse wound events. A retrospective review of patients with adolescent idiopathic scoliosis that underwent posterior spinal fusion between 2001 and 2013 was performed. Preoperative, perioperative, and postoperative data, including wound adverse events, were obtained through medical record review. Using the Center for Disease Control BMI criteria, participants were grouped into overweight/obese (BMI%≥85 percentile) or healthy/underweight (BMI%<85 percentile) groups. Obesity and prolonged hospital stay were independent risk factors for increased risk of wound problems.
