A prospective study on a series of consecutive patients. ⋯ DTI can be a useful tool to determine the pathological spinal cord levels in multilevel CSM. This information from orientation entropy-based DTI analysis, in addition to conventional MRI and clinical neurological assessment, should help spine surgeons in deciding the optimal surgical strategy.

Cross-sectional survey. ⋯ Age, sex, and race had a significant impact on SRS-22 scores in a large group of healthy adolescents. In general, scores lowered as age increased from 10 to 19 years, Caucasians scored higher in function, pain, and image than other racial groups, and Hispanics scored lower than non-Hispanics in all domains. These factors should be considered when evaluating SRS-22 scores.
-
Retrospective analysis. ⋯ Overweight and obese patients demonstrated an increased risk of postoperative complications relative to normal weight patients. Despite these findings, a BMI 25 kg/m or more was not associated with a greater risk of mortality. Further studies are warranted to characterize the impact of postoperative complications associated with overweight and obese patients on hospital resource utilization and costs after lumbar spine surgery.

Level IV, prospective case series. ⋯ This study demonstrated that lower educational attainment was associated with increased pain intensity and disability in patients with LSS, which was mediated by the coping mechanism, catastrophizing.

Retrospective analysis of kinematic magnetic resonance (MR) images. ⋯ Dynamic cord compression was most common at the C5-C6 segment. Cervical segments with greater disc bulge, more severe disc degeneration, greater angular motion, segmental kyphosis, and developmental stenosis may be at risk for missed dynamic stenosis.
