Personalized modeling of brace action has potential in improving brace efficacy in adolescent idiopathic scoliosis (AIS). Model validation and simulation uncertainty are rarely addressed, limiting the clinical implementation of personalized models. We hypothesized that a thorough validation of a personalized finite element model (FEM) of brace action would highlight potential means of improving the model. ⋯ In-depth analysis suggests that personalization of spinal functional units mechanical properties could improve the simulation's accuracy, but the model gave good results, thus justifying further research on its clinical application.

Comparative Study
Accurate prediction of height loss in adolescent idiopathic scoliosis: Cobb angle alone is insufficient.
Spinal height loss due to scoliosis was mostly calculated by equations with Cobb angle as the unique independent variable in adolescent idiopathic scoliosis (AIS), with their accuracy being seriously doubted. The purpose of this study was to compare and correlate the measured loss in spinal height (ΔSHm) with the calculated loss in spinal height (ΔSHc), and to identify the key factors associated with height loss in AIS. ⋯ Previous height correction equations employing Cobb angle as the unique independent variable are inaccurate. Cobb angle, curve length, curve inclination, and number of vertebrae within the curve are all strong determinants responsible for the height loss in AIS.

Acute pancreatitis is a possible complication after scoliosis surgery. Although some risk factors have been documented in the literature, clinical description of pancreatitis diagnosis and ensuing course still remain very poor. The aim of this study was to describe characteristics of acute pancreatitis after scoliosis surgery. ⋯ Acute pancreatitis is an early complication of scoliosis surgery. Clinical signs are atypical and non-severe and can induce misleading forms. Presence of delayed digestive problems should alert the clinician to the risk of pancreatitis in the aftermath of scoliosis surgery.

There is much variation in the choice, timing and duration of antimicrobial prophylaxis for preventing surgical site infections (SSI) but no guideline exists for scoliosis surgery. The aim of study was to compare the efficacy of two antimicrobial prophylaxis (AMP) protocols with cephazolin in preventing SSI in adolescent idiopathic scoliosis (AIS). ⋯ This is the first study on the AMP protocol in scoliosis surgery for SSI prevention. Results suggest that two doses of AMP are as effective as continued antimicrobial use until drain removal. Cephazolin appears to be effective and safe for prophylaxis.
