Higher American Society of Anesthesiologists (ASA) classification is a known predictor of postoperative complication in diverse surgical settings. However, its predictive value is not established in single-level elective anterior cervical discectomy and fusion (SLE-ACDF). ⋯ Although we did not detect associations between ASA class >II and adverse 30-day outcomes following SLE-ACDF, imprecision of estimates precludes definitive inferences. Although ASA classification allows simple assessment of patients' physiological status, their overall perioperativerisk factors need to be considered collectively for adequate optimization and improved outcomes in SLE-ACDF.

The association between early physical therapy (PT) and subsequent health-care utilization following a new visit for low back pain is not clear, particularly in the setting of acute low back pain. ⋯ Adjusted analysis found no statistically significant difference in total spine RVUs between the two groups (ratio of means 1.19, 95% CI of 0.72-1.96, p=.49). For secondary outcomes, only the difference between total spine imaging RVUs and total PT RVUs was statistically significant. The early PT group had greater PT RVUs; the ratio of means was 2.56 (95% CI of 2.17-3.03, p<.001). The early PT group had greater imaging RVUs; the ratio of means was 1.37 (95% CI of 1.09-1.71, p=.01.) CONCLUSIONS: We found that in a group of older adults presenting for a new episode of low back pain, the use of early PT is not associated with any statistically significant difference in subsequent back pain-specific health-care utilization compared with patients not receiving early PT.

Recurrence of lumbar disc herniation (rLDH) is one of the unfavorable outcomes after microdiscectomy. Prediction of the patient population with increased risk of rLDH is important because patients may benefit from preventive measures or other surgical options. ⋯ Preoperative radiographic parameters in patients with LDH can be used to assess the risk of recurrence after microdiscectomy. The multifactorial non-linear model provided more accurate rLDH probability estimation than the univariate analyses. The software developed from this model may be implemented during patient counseling or decision making when choosing the type of primary surgery for LDH.

Although most cadaveric studies of the Recurrent Laryngeal Nerve (RLN) have focused on course variations, they have usually been done on preserved (fixed and embalmed) cadavers, which renders the RLN immobile and of less surgical landmark value. ⋯ We found that the most reliable anatomical landmark for the RLN bilaterally was the ITA and Berry's ligament, both of which would be encountered as readily identifiable structures in anterior cervical spinal exposure before the nerve itself. We believe this will help spinal surgeons to refine their surgical technique to identify RLN where necessary, thus preventing iatrogenic injury. Our landmark protocol of FEEL-LOOK-AVOID can serve as an easy aide-mémoire for intraoperative surgical anatomy of the RLN during ACDF regardless of side.

Short-term readmission rates are becoming widely used as a quality and performance metric for hospitals. Data on unplanned short-term readmission after spine fusion for deformity in pediatric patients are limited. ⋯ The short-term readmission rate for pediatric spine deformity surgery is driven by patient-related factors, as well as several risk factors that may be modified to reduce this rate.
