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.

Lumbo-pelvic sagittal alignment is affected by pelvic incidence (PI), and the PI represents the compensatory capacity of lumbo-pelvic sagittal alignment. The purpose of this study was to analyze changes in lumbo-pelvic sagittal alignment between the standing and sitting positions and to analyze its association with PI. ⋯ Change in lumbo-pelvic parameters between the sitting and standing positions correlated with PI.

This study aimed to obtain reference values of lumbar lordosis (LL) and lower LL (LLL) from normal asymptomatic groups, determine the relationship between them and pelvic incidence (PI), and establish the predictive formula for ideal LLL in the elderly Korean population. ⋯ The ideal values of PI-LL and PI-LLL were inconsistent, and they have a positive correlation with PI in asymptomatic elderly population. Our data would be helpful as a normal reference value of ideal LL and LLL according to PI. These slides can be retrieved under Electronic Supplementary Material.
