    Abstract Degenerative disc disease and associated cervical spondylosis or stenosis are common conditions encountered in clinical practice. These conditions may cause progressive cervical radicular or myelopathic symptoms leading to significant impairment. Although anterior cervical discectomy and fusion (ACDF) has been a reliable surgical treatment of cervical myelopathy and radiculopathy, but limitations include loss of cervical range of motion, the concern for adjacent segment degeneration and disease, pseudoarthrosis, complications related to the choice of intervertebral graft, dysphagia, as well as standard anterior cervical approach risk. Cervical total disc arthroplasty has emerged as an alternative operative procedure to ACDF.

    Abstract Background: The National Academy of Sciences has recognized bullying as a serious public health issue, with the outcomes of bullying immediate and long-term. The purpose of this study was to examine the relationship between 7 selected positive childhood experiences, such as having a mentor, and bullying victimization, and bullying perpetration.
    Methods: We used cross sectional data from the 2019-2020 National Survey of Children's Health, children ages 6 to 17 (n = 43,999). Bivariate analyses were used, with p < .05 deemed significant. To examine the association between experiences and bullying victimization or perpetration, multivariable regression models were used.
    Results: Children who experienced any of the following positive childhood experiences had a lower odds of perpetration of bullying victimization: resilient family; safe neighborhood; supportive neighborhood; or connected caregiver. The following covariates had a lower odds of perpetrating bullying, across all models: race other than white, female sex, age of 13 or older, primary language not English, and a guardian education of a high school diploma or less.
    Implications for school health policy, practice, and equity: Schools can play a formative role in promoting positive childhood experiences identified herein.
    Conclusions: Findings from this study may be beneficial for educators, policy makers, and child advocacy stakeholders as they design and implement school or community-based youth development programs.

    Abstract Study design: A prospective multicenter clinical trial (NCT03177473) was conducted with a retrospective cohort used as a control arm.
    Objective: The purpose of this study was to evaluate cervical spine fusion rates in subjects with risk factors for pseudarthrosis who received pulsed electromagnetic field (PEMF) treatment.
    Summary of background data: Certain risk factors predispose patients to pseudarthrosis, which is associated with prolonged pain, reduced function, and decreased quality of life.
    Methods: Subjects in the PEMF group were treated with PEMF for 6 months postoperatively. The primary outcome measure was fusion status at the 12-month follow-up period. Fusion status was determined using anterior/posterior, lateral, and flexion/extension radiographs and computed tomography (without contrast).
    Results: A total of 213 patients were evaluated (PEMF, n=160; Control, n=53). At baseline, the PEMF group had a higher percentage of subjects who used nicotine ( P =0.01), had osteoporosis ( P <0.05), multi-level disease ( P <0.0001), and were >65 years of age ( P =0.01). The PEMF group showed over two-fold higher percentage of subjects that had ≥3 risk factors (n=92/160, 57.5%) compared with the control group (n=14/53, 26.4%). At the 12-month follow-up, the PEMF group demonstrated significantly higher fusion rates compared with the control (90.0% vs. 60.4%, P <0.05). A statistically significant improvement in fusion rate was observed in PEMF subjects with multi-level surgery ( P <0.0001) and high BMI (>30 kg/m 2

    P =0.0021) when compared with the control group. No significant safety concerns were observed.
    Conclusions: Adjunctive use of PEMF stimulation provides significant improvements in cervical spine fusion rates in subjects having risk factors for pseudarthrosis. When compared with control subjects that did not use PEMF stimulation, treated subjects showed improved fusion outcomes despite being older, having more risk factors for pseudarthrosis, and undergoing more complex surgeries.

    Abstract Elective lumbar surgery for common degenerative lumbar spine pathology has been consistently demonstrated to have excellent outcomes by multiple validated measures and improves patient quality of life. The rate of complication is low but not unavoidable; there is an increasing recognition of risk factors that can be mitigated to decrease complication rates. When complications occur, prompt recognition and management may minimize deleterious effects on patient outcome. There are considerations for identifying risk factors and, when possible, minimizing them and general strategies for identifying and managing common complications in lumbar spine surgery.

    Abstract Background: Very little normative computed tomography (CT) scan data exist defining expected relationships of vertebral structures in the intact cervical spine. Better understanding of normal relationships should improve sensitivity of injury detection, particularly for facet subluxation. The purpose of this paper was to describe the normal anatomical relationships and most sensitive measurements to detect abnormal alignment in the subaxial cervical spine.
    Methods: A group of 30 CT scans with no documented cervical spine injury were utilized from an established database in a trauma population. Twenty-two anatomical measurements were made for each level of the subaxial cervical spine using Microview software. For the purposes of measurement, the upper confidence limit of normal was reported as two standard deviations from the mean.
    Results: The novel, CT based measurements of bone articulation were generally smaller and had lower confidence intervals compared to traditional radiographic measurements of midline structures (such as interspinous distance, interlaminar widening, disc space widening). The upper limit of normal of facet joint height was reported (1.54 mm anterior, 1.27 mm posterior, and 2.0 mm midportion), which may help identify distractive-flexion injuries. The upper limit of normal vertebral translation (2.0 mm) was also reported to identify translation/rotation injuries.
    Conclusions: Normal CT measurements for the subaxial cervical spine, especially in the facets, were found to have small confidence limits and variation. Based upon these findings, we conclude that facet measurements and translation may be better screening tools than traditional radiographic criteria based upon midline structures. Using these measurements may improve detection of cervical spine injuries warranting further imaging or investigation and reducing missed injuries.
    Clinical relevance: Improved understanding of normal anatomic measures in the subaxial spine will allow for better screening and identification of injuries.

    Abstract Injuries to the spine comprise a high percentage of workplace injuries. Spine surgeons' evaluation of injured workers requires attention to facts specific to worker's compensation claims including whether the injury occurred in the scope of employment, whether a work incident was causally related to the injury, and whether the injury contributed to a significant degree to the patient's overall medical condition. An injured worker's compensation is subject to state-specific guidelines and is largely dependent on the degree of disability and whether the disability is temporary or permanent. Here, we review the background, organization, and key terms used in the worker's compensation system.

    Abstract Background: Lumbar spinal fusion surgeries are increasing steadily due to an aging and ever-growing population. Patients undergoing lumbar spinal fusion surgery may present with risk factors that contribute to complications, pseudarthrosis, prolonged pain, and reduced quality of life. Pulsed electromagnetic field (PEMF) stimulation represents an adjunct noninvasive treatment intervention that has been shown to improve successful fusion and patient outcomes following spinal surgery.
    Methods: A prospective, multicenter study investigated PEMF as an adjunct therapy to lumbar spinal fusion procedures in patients at risk for pseudarthrosis. Patients with at least 1 of the following risk factors were enrolled: prior failed fusion, multilevel fusion, nicotine use, osteoporosis, or diabetes. Fusion status was determined by radiographic imaging, and patient-reported outcomes were also evaluated.
    Results: A total of 142 patients were included in the analysis. Fusion status was assessed at 12 months follow-up where 88.0% (
    Conclusions: The addition of PEMF as an adjunct treatment in patients undergoing lumbar spinal surgery provided a high rate of successful fusion with significant improvements in pain, function, and quality of life, despite having risk factors for pseudarthrosis.
    Clinical relevance: PEMF represents a useful tool for adjunct treatment in patients who have undergone lumbar spinal surgery. Treatment with PEMF may result in improved fusion and patient-reported outcomes, regardless of risk factors.

    Abstract To the authors' knowledge, this is the first article to present a pedicle subtraction osteotomy in the lumbar spine to correct and stabilize a high-grade isthmic spondylolisthesis, which poses many challenges with regard to treatment options and outcomes. The optimal surgical treatment for high-grade spondylolisthesis is controversial, but the goals of treatment are to stabilize the affected spinal levels and to decompress the neural elements. A pedicle subtraction osteotomy is a reconstructive procedure that addresses fixed sagittal imbalance by increasing lumbar lordosis through posterior spinal column shortening. The authors report a 46-year-old patient with chronic, progressively worsening back and leg radiculopathy accompanied by sagittal plane malalignment and for which a pedicle subtraction osteotomy was performed. The procedure yielded stabilization of the patient's lumbar spondylolisthesis and sagittal plane alignment was restoration. At 3 months postoperatively, the patient's pain had fully resolved and her motor and neurologic examination exhibited no deficits. At 24 months postoperatively, she was still symptom-free and ambulating without assistance. This report is the first documented successful pedicle subtraction osteotomy in the treatment of high-grade spondylolisthesis. This report indicates that certain patient populations may be amenable to pedicle subtraction osteotomy as a treatment option for pathology involving high-grade isthmic spondylolisthesis.
