Study Design: Retrospective cohort study.
Objective: To evaluate intensive postoperative nutritional supplementation on wound healing complications and outcomes after spinal fusion surgery.
Background: Poor nutritional status leads to inferior postoperative outcomes by increasing mortality and predisposing patients to infection and wound healing complications.
Article Synopsis
- The study investigates the movement mechanics of the atlantooccipital joint (occiput-C1) in healthy young adults during various head movements, using high-speed biplane radiographs to capture the motion.
- Researchers tracked the joint's movements while participants performed flexion/extension, axial rotation, and lateral bending, finding significant variability in flexion/extension compared to more consistent axial and lateral movements.
- The results reveal key details about the joint's range of motion and axis of rotation during these movements, providing valuable insights for future studies on upper cervical spine biomechanics.
Study Design: Retrospective cohort.
Objective: To evaluate the clinical relevance, usefulness, and financial implications of intraoperative radiograph interpretation by radiologists in spine surgery.
Summary Of Background Data: Due to rising health care costs, spine surgery is under scrutiny to maximize value-based care.
➤ Despite being a social construct, race has an impact on outcomes in musculoskeletal spine care.➤ Race is associated with other social determinants of health that may predispose patients to worse outcomes.➤ The musculoskeletal spine literature is limited in its understanding of the causes of race-related outcome trends.

Objective: Characterize negative reviews of spine surgeons in the United States.
Summary: Physician rating websites significantly influence the selection of doctors by other patients.
Article Synopsis
- The study aimed to improve and validate a classification system for complications in adult spine surgery, as there was no standardized method available.
- Four specialized spine surgeons modified the Clavien-Dindo-Sink classification and assessed its reliability through a survey of real-life cases, repeating the survey two weeks later.
- Results showed high agreement among raters, with excellent reliability scores indicating that this modified system effectively communicates the severity of complications in spine surgery.
The Effects of Cervical Orthoses on Head and Intervertebral Range of Motion.
Spine (Phila Pa 1976)
November 2023
Article Synopsis
- This study investigated how well different types of cervical orthoses (neck braces) limit neck movements during various motions in a group of healthy adults.
- It found that while the soft collar was somewhat effective in reducing motion during flexion/extension and axial rotation, it did not restrain lateral bending.
- The hard collar proved to be more effective than the soft collar across all motions, except for specific segments during axial rotation and lateral bending.
Unlabelled: Patient values may be obscured when decisions are made under the circumstances of constrained time and limited counseling. The objective of this study was to determine if a multidisciplinary review aimed at ensuring goal-concordant treatment and perioperative risk assessment in high-risk orthopaedic trauma patients would increase the quality and frequency of goals-of-care documentation without increasing the rate of adverse events.
Methods: We prospectively analyzed a longitudinal cohort of adult patients treated for traumatic orthopaedic injuries that were neither life- nor limb-threatening between January 1, 2020, and July 1, 2021.
Purpose: Lumbar spinal stenosis (LSS) is the most common reason for spinal surgery in patients over the age of 65, and there are few effective non-surgical treatments. Therefore, the development of novel treatment or preventative modalities to decrease overall cost and morbidity associated with LSS is an urgent matter. The cause of LSS is multifactorial; however, a significant contributor is ligamentum flavum hypertrophy (LFH) which causes mechanical compression of the cauda equina or nerve roots.

J Head Trauma Rehabil
November 2023
Objective: To examine the frequency and association of neck pain symptoms in patients with a concussion.
Study Setting And Participants: Three-hundred and thirty-one consecutively enrolled patients aged 9 to 68 years with a diagnosed concussion 1 to 384 days post-injury were enrolled at a concussion clinic from a single integrated healthcare system in Western Pennsylvania between 2019 and 2021.
Design: Retrospective cohort analysis of prospectively collected concussion screening tool intake survey responses and clinical outcomes data.
Spine Fractures of Patients with Ankylosing Spondylitis and Diffuse Idiopathic Skeletal Hyperostosis: Fracture Severity and Injury-Related Mortality at a Level I Trauma Center.
Asian Spine J
June 2023
Article Synopsis
- The study involved a retrospective analysis of patients with spine fractures due to ankylosing conditions, specifically ankylosing spondylitis (AS) and diffuse idiopathic skeletal hyperostosis (DISH).
- It aimed to explore differences in treatment methods and mortality rates between these two groups over a nine-year period.
- Findings indicated that AS patients experienced more severe fractures and required surgery more often than DISH patients, yet there was no significant difference in 1-year mortality rates between the two groups.
Objective: The aim of this study was to investigate the effect of degenerative spondylolisthesis (DS) on psoas anatomy and the L4-5 safe zone during lateral lumbar interbody fusion (LLIF).
Methods: In this retrospective, single-institution analysis, patients managed for low-back pain between 2016 and 2021 were identified. Inclusion criteria were adequate lumbar MR images and radiographs.
Article Synopsis
- - Cervical sagittal alignment significantly impacts surgical outcomes, but differences in intervertebral alignment between supine and upright positions have not been previously quantified.
- - A study involving 64 patients and 47 controls found that different cervical motion segments exhibited varying lordosis levels when comparing upright and supine positions, with some segments showing increased lordosis and others decreased.
- - Results suggest that cervical alignment changes with positioning vary among segments and that conditions like cervical pathology influence these changes, emphasizing the need for surgeons to consider these differences in their clinical assessments.
Background: Previous animal models of intervertebral disc degeneration (IDD) rely on open surgical approaches, which confound the degenerative response and pain behaviors due to injury to surrounding tissues during the surgical approach. To overcome these challenges, we developed a minimally invasive percutaneous puncture procedure to induce IDD in a rat model.
Methods: Ten Fischer 344 male rats underwent percutaneous annular puncture of lumbar intervertebral discs (IVDs) at L2-3, L3-4, and L4-5.
Previous research has identified an association between external radiation and disc degeneration, but the mechanism was poorly understood. This study explores the effects of ionizing radiation (IR) on inducing cellular senescence of annulus fibrosus (AF) in cell culture and in an in vivo mouse model. Exposure of AF cell culture to 10-15 Gy IR for 5 min followed by 5 days of culture incubation resulted in almost complete senescence induction as evidenced by SA-βgal positive staining of cells and elevated mRNA expression of the p16 and p21 senescent markers.

Global Spine J
October 2023
Article Synopsis
- The study is a retrospective cohort analysis aimed at assessing how the level of caudal instrumentation affects revision rates after posterior cervical laminectomy and fusion.
- It involved analyzing a database of 204 patients over a minimum follow-up of one year, dividing them into two groups based on where their fusion ended—cervical (C7) or thoracic (T1/T2).
- Findings indicated that the overall revision rate was similar between both groups (7.3% for cervical and 10.4% for thoracic), and no independent risk factors for revision surgery were identified, suggesting that fusion constructs can safely end at the cervical spine without increasing revision risk.
For individuals with Down syndrome (DS), obstructive sleep apnea (OSA) is a complex disorder with significant clinical consequences. OSA is seen frequently in DS, and when present, it tends to be more severe. This increased prevalence is likely related to common anatomic abnormalities and a greater risk of additional comorbidities such as hypotonia and obesity.
