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.

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.

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.

A matched-pairs animal study. ⋯ The MRI technique is an accuracy means of evaluating multifidus muscle injury and atrophy.

Retrospective case series of surgically treated patients with adult spine deformity (ASD). ⋯ The incidence of PJF among surgically treated patients with ASD was 1.4%. The most common type of PJF was 2N. Preoperative large sagittal vertical axis change and large amount of correction was a causative factor for spondylolisthesis above the UIV. After the revision surgery, further PJF was a commonly occurred event.
