Multicenter Study Observational Study
Accurate prediction of spontaneous lumbar curve correction following posterior selective thoracic fusion in adolescent idiopathic scoliosis using logistic regression models and clinical rationale.
Accurate prediction of spontaneous lumbar curve correction (SLCC) after selective thoracic fusion (STF) remains difficult. This study sought to improve prediction accuracy of SLCC. The hypothesis was preoperative and intraoperative variables could predict SLCC < 20°. ⋯ An accurate prediction model for postoperative SLCC was established based on a large analysis of prospective STF cases. These models can support prediction and understanding of postoperative SLCC aiding in surgical decision making when contemplating a selective thoracic fusion.

Multicenter Study
Quasi-automatic early detection of progressive idiopathic scoliosis from biplanar radiography: a preliminary validation.
To validate the predictive power and reliability of a novel quasi-automatic method to calculate the severity index of adolescent idiopathic scoliosis (AIS). ⋯ The fast and semiautomatic method for 3D reconstruction developed in this work allowed for a fast and reliable calculation of the severity index. The method is fast and user friendly. Once extensively validated, this severity index could allow very early initiation of conservative treatment for progressive patients, thus increasing treatment efficacy and therefore reducing the need for corrective surgery.

To test the hypothesis that the relationship between PI and L1-S1 lumbar lordosis (LL) is always positive, even in cases with different lumbar sagittal profiles. ⋯ Contrary to the hypothesis, the correlation coefficient between PI and LL was not significant in the cases with apex above L3, suggesting that the relationship between PI and LL is not always constant, and whole sagittal alignment should be taken into account.

Information regarding the impact of provider characteristics on perioperative outcomes in the spine surgery setting is limited. Existing studies primarily consider the impact of surgical provider volume. This analysis sought to identify the impact of anesthesiologist and surgeon volume and experience as well as anesthesia care team composition on adverse outcomes following anterior cervical discectomy and fusions (ACDF) and posterior lumbar fusions (PLF). ⋯ Anesthesia provider volume and experience did not significantly impact the odds of adverse outcome for ACDF and PLF patients. Higher surgeon volume was exclusively associated with decreased odds of prolonged length of stay following PLF. Further study is necessary to determine if these relationships persist in a less-specialized setting. These slides can be retrieved under Electronic Supplementary Material.

As the population continues to age, the number of lumbar spine surgeries continues to increase. While there are many complications associated with lumbar surgeries, a myocardial infarction (MI) is a particularly devastating one. This complication is of considerable importance with mortality rates of postoperative MI documented between 26.5 and 70%. This study aimed to determine the relationship between lumbar surgeries, preoperative diagnoses (risk factors), and myocardial infarction. ⋯ Preoperative risk factors, patient demographics, and procedure type had a significant effect on the incidence of postoperative myocardial infarction.
