OBJECTIVEPatients with lumbar spinal stenosis (LSS) tend to bend forward to relieve neurological symptoms. They therefore have a positive sagittal vertical axis (SVA). The importance of the SVA value is well known in the field of adult spinal deformity; however, little is known about its impact on LSS. ⋯ Group post-I had a significantly worse JOA score recovery rate, postoperative symptom severity domain score in the ZCQ, and NRS score for postoperative LBP. Similarly, the postoperative RMDQ score and the Physical Component Summary score of the SF-8 were significantly worse in group post-I. CONCLUSIONSPositive SVA had significantly negative effects on clinical outcome and HRQOL in LSS patients after lumbar decompression surgery.

OBJECTIVEEnhanced recovery after surgery (ERAS) protocols address pre-, peri-, and postoperative factors of a patient's surgical journey. The authors sought to assess the effects of a novel ERAS protocol on clinical outcomes for patients undergoing elective spine or peripheral nerve surgery. METHODSThe authors conducted a prospective cohort analysis comparing clinical outcomes of patients undergoing elective spine or peripheral nerve surgery after implementation of the ERAS protocol compared to a historical control cohort in a tertiary care academic medical center. ⋯ Postoperative Foley use was decreased in the ERAS group (20.4% vs 47.3%, p < 0.001) without an increase in the rate of straight catheterization (8.1% vs 11.9%, p = 0.51). CONCLUSIONSImplementation of this novel ERAS pathway safely reduces patients' postoperative opioid requirements during hospitalization and 1 month postoperatively. ERAS results in improved postoperative mobilization and ambulation.

OBJECTIVEThe purpose of this study was to determine the relationship between vertebral bodies, psoas major morphology, and the course of lumbar nerve tracts using diffusion tensor imaging (DTI) before lateral interbody fusion (LIF) to treat spinal deformities. METHODSDTI findings in a group of 12 patients (all women, mean age 74.3 years) with degenerative lumbar scoliosis (DLS) were compared with those obtained in a matched control group of 10 patients (all women, mean age 69.8 years) with low-back pain but without scoliosis. A T2-weighted sagittal view was fused to tractography from L3 to L5 and separated into 6 zones (zone A, zones 1-4, and zone P) comprising equal quarters of the anteroposterior diameters, and anterior and posterior to the vertebral body, to determine the distribution of nerves at various intervertebral levels (L3-4, L4-5, and L5-S1). ⋯ On the convex side, the nerves showed a posterior shift. In LIF, a convex approach is relatively safer than an approach from the concave side. Lumbar nerve course tracking with DTI is useful for assessing patients with DLS before LIF.

OBJECTIVE: The aim of this study was to determine the inter-rater reliability of the modified Medical Research Council (MRC) scale for grading motor function in patients with chronic incomplete spinal cord injury (SCI). METHODS: Two neurosurgical residents and 2 faculty members performed motor examinations in 6 chronic incomplete SCI patients for a total of 156 muscle groups. Examinations were performed using the modified MRC grading scale during routine clinic visits for each patient. Informed consent was obtained prior to enrollment. ⋯ An additional 7% showed poor inter-rater reliability (ICC < 0.4). The remaining variables tested did not reach statistical significance. CONCLUSIONS: The inter-rater reliability of the modified MRC scale was found to be high in the majority of tested variables, but the results suggest that discrepancy among trained observers does exist. Reliability was greatest in the lower-extremity muscle groups and least in the upper-extremity muscle groups in patients with chronic incomplete SCI.

OBJECTIVEThe Clinician and Group Consumer Assessment of Healthcare Providers and Systems (CG-CAHPS) is a standardized patient experience survey that is used to evaluate the quality of care delivered by physicians. The authors sought to determine which factors influenced CG-CAHPS scores for spine surgery, and compare them to their cranial-focused cohorts. METHODSA retrospective study of prospectively obtained data was performed to evaluate CG-CAHPS scores. ⋯ Office location also affected provider ratings for spine neurosurgeons. These results suggest that physician ratings obtained via patient experience surveys may be representative of factors aside from just the quality of physician care provided. This information should be considered as payers, government, and health systems design performance programs based on patient experience scores.
