Abnormal anthropometry including comparably lower weight and body mass index (BMI) in the adolesc... more Abnormal anthropometry including comparably lower weight and body mass index (BMI) in the adolescent idiopathic scoliosis (AIS) population is increasingly recognised, however, no study has examined postoperative weight loss or its clinical relevance in these relatively thin patients. This study aimed to assess perioperative nutritional status as well as clinically severe involuntary weight loss and its impact on outcomes in patients with AIS undergoing posterior spinal fusion (PSF). A further objective was to compare preoperative anthropometric measurements of the current AIS cohort with healthy controls. Seventy-seven consecutive and eligible patients with AIS who underwent PSF were prospectively followed up from hospital admission (January 2010-April 2012). Pre- and postoperative anthropometric measurements were collected (weight, height, BMI), and clinically severe unintentional weight loss computed, defined as loss of >10 % body weight from admission to hospital discharge.
