Abstract
PURPOSE To determine existing trends concerning in-hospital mortality in patients with traumatic subaxial cervical spinal cord injury (SCI) over the last four decades. METHODS We searched MEDLINE and EMBASE to assess the role of the following factors on in-hospital mortality over the last four decades: neurological deficit, age, surgical decompression, use of computed tomography (CT) and magnetic resonance imaging (MRI), use of methylprednisolone in the acute post-injury period, and study location (developing versus developed countries). RESULTS Among 3333 papers after deduplication, 21 studies met the eligibility criteria. The mortality rate was 17.88% [95% confidence interval (CI): 12.9-22.87%]. No significant trend in mortality rate was observed over the 42-year period (meta-regression coefficient = 0.317; p = 0.372). Subgroup analysis revealed no significant association between acute subaxial cervical SCI-related mortality when stratified by use of surgery, administration of methylprednisolone, use of MRI and CT imaging, study design (prospective versus retrospective study), and study location. The mortality rate was significantly higher in complete SCI (20.66%, p = 0.002) and American Spinal Injury Association impairment scale (AIS) A (20.57%) and B (9.28%) (p = 0.028). CONCLUSION A very low level of evidence showed that in-hospital mortality in patients with traumatic subaxial cervical SCI did not decrease over the last four decades despite diagnostic and therapeutic advancements. The overall acute mortality rate following subaxial cervical SCI is 17.88%. We recommend reporting a stratified mortality rate according to key factors such as treatment paradigms, age, and severity of injury in future studies.

Abstract
Spinal cord injury (SCI) remains a severe condition with an extremely high disability rate. The challenges of SCI repair include its complex pathological mechanisms and the difficulties of neural regeneration in the central nervous system. In the past few decades, researchers have attempted to completely elucidate the pathological mechanism of SCI and identify effective strategies to promote axon regeneration and neural circuit remodeling, but the results have not been ideal. Recently, new pathological mechanisms of SCI, especially the interactions between immune and neural cell responses, have been revealed by single-cell sequencing and spatial transcriptome analysis. With the development of bioactive materials and stem cells, more attention has been focused on forming intermediate neural networks to promote neural regeneration and neural circuit reconstruction than on promoting axonal regeneration in the corticospinal tract. Furthermore, technologies to control physical parameters such as electricity, magnetism and ultrasound have been constantly innovated and applied in neural cell fate regulation. Among these advanced novel strategies and technologies, stem cell therapy, biomaterial transplantation, and electromagnetic stimulation have entered into the stage of clinical trials, and some of them have already been applied in clinical treatment. In this review, we outline the overall epidemiology and pathophysiology of SCI, expound on the latest research progress related to neural regeneration and circuit reconstruction in detail, and propose future directions for SCI repair and clinical applications.

Abstract
Introduction The evaluation of cervical-spine in a major trauma patient needs a bedside efficient tool to rule out cervical spine injury as the role of X-ray and Computed Tomography (CT) in this setting is limited. Point of care ultrasonography (POCUS) is being used as an adjunct during trauma resuscitation. The aim of this study was to evaluate the use of POCUS for identifying cervical spine injuries. Methods We recruited 84 cases with cervical spine injury based on CT scan after taking consent. POCUS was used as per the operational definition of study methods while maintaining manual in-line stabilisation. Statistical analysis was done by using STATA version 14. Results Normal cervical anatomy was visible through anterior approach in POCUS except for the 1st and 2nd cervical vertebrae. The sensitivity and specificity of POCUS vs CT scan for vertebral body listhesis were 84.52% (95% CI of 0.65-0.95) and 89.66% (95% CI 0.78-0.96) with p-value <0.0001. Sensitivity and specificity of POCUS vs CT for vertebral body fracture were 40.91% (95% CI of 0.20-0.63) and 96.77% (95% CI of 0.88-0.99) with p-value <0.0001. The overall sensitivity and specificity of POCUS were 45.83% and 83.33% (p = 0.06) and excluding isolated posterior column injuries, sensitivity and specificity were 70.21% and 83.33% (p < 0.05). Conclusion POCUS identified injuries such as fracture and listhesis. Because of high rate of missed injuries, ultrasound at present cannot be used as a screening or diagnostic tool for decision-making in cervical spine injury.

Abstract
ABSTRACT Objectives: To evaluate the epidemiological profile of patients with spinal fractures over a two-year period (2017 and 2018) in a quaternary hospital in the city of São Paulo. Methods: A cross-sectional study was carried out through the analysis of the electronic medical records of patients treated by the Spine group of the Department of Orthopedics and Traumatology at the Orthopedics and Traumatology Emergency Room of Hospital das Clínicas de São Paulo in the years 2017 and 2018. Results: A total of 185 patients were evaluated over two years. Males were the gender most frequently evaluated (69.19%), and the mean patient age was 43.95 years. The most common trauma mechanisms were falls from a height (45.95%) and traffic accidents (29.73%). The cervical spine, affected in 28.65%, was the most affected region, followed by the thoracolumbar region (26.56%). Most patients did not present deficits at the initial moment (71.89%) and 54.05% of patients underwent surgery for treatment. Conclusion: Most traumas involving the spine affect adults of working age (from 20 to 60 years old), with a predominance of males. Most injuries occurred in the cervical region, which is the region most commonly associated with severe trauma and neurological injuries. This study can help in planning prevention and precaution strategies for spinal trauma. Level of evidence III; Cross-sectional study.

Abstract
STUDY DESIGN Retrospective cross-sectional study. OBJECTIVE To describe the epidemiological profile of individuals with spinal cord injury (SCI), who visited the Sarah Network in 2014. SETTING Brazil, Brasília-Federal District. METHODS A review of the electronic medical records of persons with SCI, aged over 15 years, was carried out. RESULTS The medical records of 2076 persons were evaluated: 83% were male, the mean age was 31 years, 40% did not complete elementary school, 67.7% had paraplegia, and 74.4% had complete SCI. The primary etiologies were gunshot wounds (28.4%), motorcycle accidents (24.6%), and motor vehicle accidents (19.1%). In the comparative analysis between genders, differences were observed regarding the level of education and completeness of injury. CONCLUSION Gunshot wounds were the main cause of SCI in our population, comprising mostly male individuals with thoracic injury, resulting in complete SCI. Data show a high incidence of SCI in young adults owing to violence in Brazil.

Abstract
Background: The classical clinical presentation, neuroradiographic features, and conservative vs. surgical management of traumatic cervical central spinal cord (CSS) injury remain controversial. Methods: CSS injuries, occurring in approximately 9.2% of all cord injuries, are usually attributed to significant hyperextension trauma combined with congenital/acquired cervical stenosis/spondylosis. Patients typically present with greater motor deficits in the upper vs. lower extremities accompanied by patchy sensory loss. T2-weighted magnetic resonance (MR) scans usually show hyperintense T2 intramedullary signals reflecting acute edema along with ligamentous injury, while noncontrast computed tomography (CT) studies typically show no attendant bony pathology (e.g. no fracture, dislocation). Results: CSS constitute only a small percentage of all traumatic spinal cord injuries. Aarabi et al. found CSS patients averaged 58.3 years of age, 83% were male and 52.4% involved accidents/falls in patients with narrowed spinal canals (average 5.6 mm); their average American Spinal Injury Association (ASIA) motor score was 63.8, and most pathology was at the C3-C4 and C4-C5 levels (71%). Surgery was performed within 24 h (9 patients), 24–48 h (10 patients), or after 48 h (23 patients). In the Brodell et al. study of 16,134 patients with CSS, 39.7% had surgery. In the Gu et al. series, those with CSS and stenosis/ossification of the posterior longitudinal ligament (OPLL) exhibited better outcomes following laminoplasty. Conclusions: Recognizing the unique features of CSS is critical, as the clinical, neuroradiological, and management strategies (e.g. conservative vs. surgical management: early vs. late) differ from those utilized for other spinal cord trauma. Increased T2-weighted MR images best document CSS, while CT studies confirm the absence of fracture/dislocation.
