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.

Lumbar spine fusion with anterior (ALIF) or lateral (LLIF) approach is a moderately painful procedure associated with significant length of hospital stay (LoS) and opioid requirements. We developed an opioid-sparing analgesic pathway of care for ALIF and LLIF, featuring transversus abdominis plane (TAP) block. In this study, we assessed the feasibility of performing the TAP block as an analgesic adjunct for ALIF or LLIF. ⋯ Applying TAP block to spine surgery is a novel pain management strategy. This study demonstrates high patient acceptance and the general safety of the technique. Although lacking a control arm, these results also provide preliminary data supporting efficacy.

Major complications are a concern following ASD surgery. Even when properly managed and resolved, they may still have a relevant impact on HRQL. We aimed to investigate the impact of resolved early major complications on 2-year outcome after ASD surgery. ⋯ The results indicate that patients experiencing major complications after ASD surgery have significantly less functional improvement (SRS-22 function, ODI, SF-36 PCS) than their complication-free counterparts, even when complications were considered resolved, and the outcome was measured after an 18-month complication-free period.

To investigate whether quantitative T2-times depend on lumbar intervertebral disc (IVD) level. ⋯ Significant level-dependent T2-time differences within several Pfirrmann grades, both for the entire IVD volume and for multiple IVD subregions, were shown in this large cohort study. The T2-time differences between levels existed in both non-degenerated and degenerated IVDs. These findings show the importance of stratifying for lumbar level when quantitative IVD studies are performed using T2-mapping. These slides can be retrieved under Electronic Supplementary Material.

To determine the relationship between the bone formation-related functions of GPR126 and the structural asymmetry of spine in adolescent idiopathic scoliosis (AIS). ⋯ Our findings indicated that GPR126-NTFs play a role in skeletal development, and the inclusion/exclusion of exon6 may regulate the bone formation-related functions of GPR126. The convex/concave asymmetric expression of GPR126-exon6in may be an important factor in abnormal bone formation of AIS. These slides can be retrieved under Electronic Supplementary Material.
