Traumatic spine injuries in the geriatric population

Epidemiological age-based differences in traumatic spinal cord injury patients: A multicenter study based on 13,334 inpatients

CONTEXT

Compared with younger traumatic spinal cord injury (TSCI) patients, the elderly had longer delays in admission to surgery, higher proportion of incomplete injury, and longer hospital stays. However, in China, the country with the largest number of TSCI patients, there have been no large-scale reports on their age differences.

OBJECTIVES

To explore the age-based differences among TSCI inpatients, focusing on the demographic and clinical characteristics, treatment status, and economic burden.

METHODS

We collected the medical records of 13,334 inpatients with TSCI in the 30 hospitals of China, from January 1, 2013 to December 31, 2018. Trends are expressed as annual percentage changes (APCs) and 95% confidence intervals (CIs).

RESULTS

A total of 13,334 inpatients were included. Both the number and proportion of the elderly showed an increasing trend. The APC of the number and proportion in patients ≥85 years were 39.5% (95% CI, 14.3 to 70.3; P < 0.01) and 30.5% (95% CI, 8.6 to 56.9; P < 0.01), respectively. Younger patients were more likely to undergo decompression surgery, and older patients were more likely to receive high-dose methylprednisolone sodium succinate/methylprednisolone (MPSS/MP). Of the patients ≥85 years, none underwent decompression surgery within 8 h, and only 1.4% received a high dose of MPSS/MP within 8 h after injury. Elderly patients had lower hospitalization costs than younger. The total and daily medical costs during hospitalization of patients ≥85 years were 8.06 ± 18.80 (IQR: 5.79) and 0.61 ± 0.73 (IQR: 0.55) thousands dollars, respectively.

CONCLUSIONS

As the first study to focus on age differences of TSCI patients in China, this study found many differences, in demographic and clinical characteristics, treatment status, and economic costs, between older and younger TSCI patients. The number and proportion of elderly patients increased, and the rate of early surgery for elderly patients is low.

A systematic review and meta-analysis of the global epidemiology of pediatric traumatic spinal cord injuries

Despite being relatively rare, pediatric traumatic spinal cord injury (TSCI) is a debilitating event with high morbidity and long-term damage and dependency. This study aims to provide insight on the epidemiological characteristics of pediatric TSCI worldwide. The studies were included if they provided data for the pediatric population with the diagnosis of TSCI. Information sources included PubMed, Embase, Web of Science, and Scopus. All databases were searched from 1990 to April 2023. The quality of included studies was evaluated by Joanna Briggs Institute Critical Appraisal Tools. The results of the meta-analysis were presented as forest plots. PROSPERO Registration code: CRD42020189757. We identified 87 studies from 18 developed and 11 developing countries. Of the 87 studies evaluated, 52 studies were considered medium quality, 27 studies were considered high quality, and 8 studies were considered low quality. In developed countries, the proportion of TSCIs occurring in patients aged 0-15 years was 3% (95% CI: 2.2%; 3.9%), while in developing countries, it was 4.5% (95% CI: 2.8%; 6.4%). In developed countries, the pooled incidence of pediatric TSCI was 4.3/millions of children aged 0-15/year (95% CI: 3.1; 6.0/millions children aged 0-15/year) and boys comprised 67% (95% CI: 63%; 70%) of cases. The most prevalent level of injury was cervical (50% [95% CI: 41%; 58%]). The frequency of SCI Without Obvious Radiological Abnormality (SCIWORA) was 35% (95% CI: 18%; 54%) among children 0-17 years. The most common etiology in developed countries was transport injuries (50% [95% CI: 42%; 57%]), while in developing countries falls were the leading cause (31% [95% CI: 20%; 42%]). The most important limitation of our study was the heterogeneity of studies in reporting age subgroups that hindered us from age-specific analyses.   Conclusion: Our study provided accurate estimates for the epidemiology of pediatric TSCI. We observed a higher proportion of pediatric TSCI cases in developing countries compared to developed countries. Furthermore, we identified distinct epidemiological characteristics of pediatric TSCI when compared to adult cases and variations between developing and developed countries. Recognizing these unique features allows for the implementation of cost-effective preventive strategies aimed at reducing the incidence and burden of TSCI in children. What is Known: • Pediatric Traumatic Spinal Cord Injury (TSCI) can have profound physical and social consequences for affected children, their families, and society as a whole. • Epidemiological insights are vital for they provide the data and understanding needed to the identification of vulnerable populations, aiding in the development of targeted prevention strategies and effective resource allocation. What is New: • The estimated incidence of pediatric TSCI in developed countries is 4.3 cases per million children aged 0-15. The proportion of pediatric TSCI cases in relation to all-age TSCI cases is 3% in developed countries and 4.5% in developing countries. • The etiology of TSCI in pediatric cases differs between developing and developed countries. In developed countries, transport injuries are the most prevalent cause of pediatric TSCI, while falls are the least common cause. Conversely, in developing countries, falls are the leading cause of pediatric TSCI.

Thoraco-lumbar-sacral orthoses in older people - A narrative literature review

Fractures in the thoracolumbar region have a bimodal distribution, with an increasing number of older people presenting with acute vertebral fractures after atraumatic or low energy mechanisms of injury. In the absence of neurological compromise and significant vertebral instability, thoracolumbar fractures are often managed conservatively and bracing is widely recommended. However, in older cohorts, bracing is often ill fitting and poorly tolerated with non-compliance leading to prolonged immobilization. Systematic reviews and meta-analyses have challenged the motive of bracing, but as evidence quality is low, the role of exploratory analysis has been limited. This descriptive review summarises and examines the current evidence that underpins the use of spinal orthoses, specific to older patients, in an effort to streamline its judicious use in clinical practice and identify scope to direct further research.

Geriatric spine fractures - Demography, changing trends, challenges and special considerations: A narrative review

The aim of this manuscript was to summarize the demography and changing trends of geriatric spinal injuries and to enumerate the challenges and special considerations in the care of geriatric spinal injuries. PubMed, Scopus and Embase databases were searched for literature on geriatric spine fractures using MeSH terms 'aged', 'aged, 80 and over', 'elderly', 'spinal fracture/epidemiology', spinal fracture/therapy∗' and keywords pertaining to the same. The search results were screened for appropriate articles and reviewed. There is a high community prevalence of elderly vertebral fractures ranging from 18% to as high as 51%. The proportion of older patients among the spinal injured is rising as well. There is a higher chance of missing spinal injuries in the elderly and clinical guidelines may not be applicable to this patient group. Classification and surgical treatment are different from younger adult counterparts as the elderly osteoporotic spine behaves differently biomechanically. There is a high incidence of respiratory complications both for surgically and conservatively managed groups. Older age generally is associated with a higher complication rate including mortality.

Perioperative morbidity and mortality in octogenarians sustaining traumatic osteoporotic type 4 and 5 thoracolumbar and lumbar fractures: a retrospective study with 3 years follow-up

PURPOSE

This study aimed to guide the more efficient management of type 4 and 5 thoracolumbar or lumbar osteoporotic fractures (OF) in patients aged 80 years and older with an acute onset of neurological decline. This aim was achieved by assessing the clinical course and morbidity and mortality rates and identifying potential risk factors for patient mortality METHODS: Electronic medical records were retrieved from a single institution pertaining to the period between September 2005 and December 2020. Data on patient demographics, neurological conditions, surgical characteristics, complications, hospital course, and 90-day mortality were also collected.

RESULTS

Over a 16-year period, 35 patients aged ≥80 years diagnosed with thoracolumbar and lumbar OF were enrolled in the study. The mean Charlson comorbidity index (CCI) was >6, indicating a poor baseline reserve (9.4 ± 1.9), while cardiovascular diseases were the most prevalent among comorbidities. The mean surgical duration was 231.6 ± 89.3 min, with a mean blood loss of 694.4± 200.3 mL. The in-hospital was 8.6% and 90-day mortality rates at 11.4%. Two patients underwent revision surgery for deep wound infection. Intraoperative and postoperative radiography and computed tomography (CT) imaging revealed correct screw placement. Proper alignment of the thoracolumbar spine was achieved in all the patients. Unique risk factors for mortality included the presence of comorbidities and the occurrence of postoperative complications.

CONCLUSIONS

Emergent instrumentation in patients with acute onset of neurological decline and potentially unstable spines due to thoracolumbar and lumbar OF improved functional outcomes at discharge. Age should not be a determinant of whether to perform surgery.

Epidemiological characteristics of traumatic spinal cord injuries in a multicenter retrospective study in northwest China, 2017-2020

Background

Traumatic spinal cord injuries (TSCIs) are worldwide public health problems that are difficult to cure and impose a substantial economic burden on society. There has been a lack of extensive multicenter review of TSCI epidemiology in northwest China during the Corona Virus Disease 2019 (COVID-19) pandemic.

Method

A multicenter retrospective study of 14 selected hospitals in two provinces in northwest China was conducted on patients admitted for TSCI between 2017 and 2020. Variables assessed included patient demographics, etiology, segmental distribution, treatment, waiting time for treatment, and outcomes.

Results

The number of patients with TSCI showed an increasing trend from 2017 to 2019, while there were 12.8% fewer patients in 2020 than in 2019. The male-to-female ratio was 3.67:1, and the mean age was 48 ± 14.9 years. The primary cause of TSCI was high falls (38.8%), slip falls/low falls (27.7%), traffic accidents (23.9%), sports (2.6%), and other factors (7.0%). The segmental distribution showed a bimodal pattern, peak segments were C6 and L1 vertebra, L1 (14.7%), T12 (8.2%), and C6 (8.2%) were the most frequently injured segments. In terms of severity, incomplete injury (72.8%) occurred more often than complete injury (27.2%). The American Spinal Injury Association impairment scale of most patients did not convert before and after treatment in the operational group (71.6%) or the conservative group (80.6%). A total of 975 patients (37.2%) from urban and 1,646 patients (62.8%) from rural areas were included; almost all urban residents could rush to get treatment after being injured immediately (<1 h), whereas most rural patients get the treatment needed 4-7 h after injury. The rough annual incidence from 2017 to 2020 is 112.4, 143.4, 152.2, and 132.6 per million people, calculated by the coverage rate of the population of the sampling hospital.

Conclusion

The incidence of TSCI in northwest China is high and on the rise. However, due to pandemic policy reasons, the incidence of urban residents decreased in 2020. The promotion of online work may be an effective primary prevention measure for traumatic diseases. Also, because of the further distance from the good conditional hospital, rural patients need to spend more time there, and the timely treatment of patients from remote areas should be paid attention to.

Adverse Events Relating to Prolonged Hard Collar Immobilisation: A Systematic Review and Meta-Analysis

STUDY DESIGN

Systematic review and meta-analysis.

OBJECTIVE

To evaluate systematically the complications of prolonged cervical immobilisation in a hard collar.

METHODS

Following registration with PROSPERO, a systematic search of electronic databases (MEDLINE, EMBASE) was conducted. Two reviewers independently screened the search results according to pre-determined search criteria. Data was extracted and tabulated. Joanna Briggs Institute checklists were used for assessing the quality of included studies.

RESULTS

The search identified 773 articles. A total of 25 studies were selected for final inclusion. The results largely comprised a mixture of case reports/series, cohort studies and reviews. The most commonly reported complications were pressure ulcers, dysphagia and increased intracranial pressure. A pressure ulcer pooled prevalence of 7% was calculated. There was insufficient data for quantitative analysis of any other complication.

CONCLUSIONS

There is significant morbidity from prolonged hard collar immobilisation, even amongst younger patients. Whilst based upon limited and low-quality evidence, these findings, combined with the low-quality evidence for the efficacy of hard collars, highlights a knowledge gap for future research.

Advances in monitoring for acute spinal cord injury: a narrative review of current literature

Spinal cord injury (SCI) is a devastating condition that affects about 17,000 individuals every year in the United States, with approximately 294,000 people living with the ramifications of the initial injury. After the initial primary injury, SCI has a secondary phase during which the spinal cord sustains further injury due to ischemia, excitotoxicity, immune-mediated damage, mitochondrial dysfunction, apoptosis, and oxidative stress. The multifaceted injury progression process requires a sophisticated injury-monitoring technique for an accurate assessment of SCI patients. In this narrative review, we discuss SCI monitoring modalities, including pressure probes and catheters, micro dialysis, electrophysiologic measures, biomarkers, and imaging studies. The optimal next-generation injury monitoring setup should include multiple modalities and should integrate the data to produce a final simplified assessment of the injury and determine markers of intervention to improve patient outcomes.

Developing a National Trauma Research Action Plan: Results from the Neurotrauma Research Panel Delphi Survey

BACKGROUND

In 2016, the National Academies of Science, Engineering and Medicine called for the development of a National Trauma Research Action Plan. The Department of Defense funded the Coalition for National Trauma Research to generate a comprehensive research agenda spanning the continuum of trauma and burn care. Given the public health burden of injuries to the central nervous system, neurotrauma was one of 11 panels formed to address this recommendation with a gap analysis and generation of high-priority research questions.

METHODS

We recruited interdisciplinary experts to identify gaps in the neurotrauma literature, generate research questions, and prioritize those questions using a consensus-driven Delphi survey approach. We conducted four Delphi rounds in which participants generated key research questions and then prioritized the importance of the questions on a 9-point Likert scale. Consensus was defined as 60% or greater of panelists agreeing on the priority category. We then coded research questions using an National Trauma Research Action Plan taxonomy of 118 research concepts, which were consistent across all 11 panels.

RESULTS

Twenty-eight neurotrauma experts generated 675 research questions. Of these, 364 (53.9%) reached consensus, and 56 were determined to be high priority (15.4%), 303 were deemed to be medium priority (83.2%), and 5 were low priority (1.4%). The research topics were stratified into three groups-severe traumatic brain injury (TBI), mild TBI (mTBI), and spinal cord injury. The number of high-priority questions for each subtopic was 46 for severe TBI (19.7%), 3 for mTBI (4.3%) and 7 for SCI (11.7%).

CONCLUSION

This Delphi gap analysis of neurotrauma research identified 56 high-priority research questions. There are clear areas of focus for severe TBI, mTBI, and spinal cord injury that will help guide investigators in future neurotrauma research. Funding agencies should consider these gaps when they prioritize future research.

Pediatric Spine Trauma

Pediatric spine has growth potential with incomplete ossification, and also unique biomechanics which have important implications for trauma patients. This article intends to review various aspects of pediatric spine trauma including epidemiology, anatomy and biomechanics, and clinically relevant details of each type of injury based on the location and mechanism of injury. With the appropriate but not superfluous treatment, pediatric spine trauma patients can have better chance of recovery. Therefore, as a spine surgeon, understanding the general concept for each injury subtype together with the debate and progress in the field is inevitable.

Elderly traumatic central cord syndrome in the United States: a review of management and outcomes

INTRODUCTION

As the incidence of elderly spinal cord injury rises, improved understanding of risk profiles and outcomes is needed. This review summarizes clinical characteristics, management, and outcomes specific to the elderly (≥65-years) with acute traumatic central cord syndrome in the United States.

EVIDENCE AQUISITION

Literature review of the PubMed, Embase, and CINAHL databases (01/2007-03/2020) regarding elderly subjects with acute traumatic central cord syndrome.

EVIDENCE SYNTHESIS

Nine studies met inclusion criteria. Acute traumatic central cord syndrome was more common among married (50%), Caucasian (22-71%) males (63-86%) with an annual income <40,999 U.S. dollars (30%). Mechanisms consisted predominantly of traumatic falls (32-55%) and motor vehicle collisions (15-34%), with admission American Spinal Injury Association Impairment Scale grades D (25-79%) and C (21-51%). Mortality was 2-3%. American Spinal Injury Association Impairment Scale motor score, maximum canal compromise, and extent of parenchymal damage were predictors of one-year recovery. Greater comorbidities (heart failure, weight loss, coagulopathy, diabetes), lower income (<51,000 U.S. dollars), and age ≥80 were predictors of mortality. A substantial cohort underwent surgery (40-45%). Elderly patients were less likely to receive surgical intervention, and surgery timing had variable effects on recovery.

CONCLUSIONS

Elderly patients with acute traumatic central cord syndrome are uniquely at risk due to cumulative comorbidities, protracted recovery times, and unclear effects of surgical timing on outcomes. Prospective research should focus on validating age-specific risk factors, formalizing surgical indications, and delineating the impact of time to surgery on acute and long-term outcomes for this condition.

Acute Traumatic Spinal Cord Injury

Traumatic spinal cord injury is a common neurologic insult worldwide that can result in severe disability. Early stabilization of the patient's airway, breathing, and circulation as well as cervical and thoracolumbar spinal immobilization is necessary to prevent additional injury and optimize outcomes. Computed tomography (CT) scan and magnetic resonance imaging (MRI) of the spinal column can assist with determining the extent of bony and ligamentous injury, which will guide surgical management. With or without surgical intervention, patients with spinal cord injury require intensive care unit management and close observation to monitor for potential complications.

Spinal Cord Transection in a Type II Odontoid Fracture From a Ground-Level Fall

Odontoid fractures typically occur as a result of trauma: high-velocity injuries like motor vehicle accidents in young people and falls for the elderly. Odontoid fractures are the most common cervical spine fractures in patients over 65, with type II being the most common. However, spinal cord transections are rare with these types of injuries, especially without significant fracture displacement, translation or evidence of ligamentous disruption on post-injury imaging. We report a case of a patient who sustained a spinal cord transection secondary to an acute type II odontoid fracture from a ground-level fall, without computed tomography radiographic evidence of cord disruption or impingement.

In-Hospital Mortality for the Elderly with Acute Traumatic Spinal Cord Injury

As the incidence of traumatic spinal cord injury (tSCI) in the elderly rises, clinicians are increasingly faced with difficult discussions regarding aggressiveness of management, likelihood of recovery, and survival. Our objective was to outline risk factors associated with in-hospital mortality in elderly surgical and non-surgical patients following tSCI and to determine those unlikely to have a favorable outcome. Data from elderly patients (≥ 65 years of age) in the Canadian Rick Hansen SCI Registry from 2004 to 2017 were analyzed using descriptive analysis. Survival and mortality groups in each of the surgical and non-surgical group were compared to explore factors associated with in-hospital mortality and their impact, using logistical regression. Of 1340 elderly patients, 1018 had surgical data with 826 having had surgery. In the surgical group, the median time to death post-injury was 30 days with 75% dying within 50 days compared with 7 days and 20 days, respectively, in the non-surgical group. Significant predictors for in-hospital mortality following surgery are age, comorbidities, neurological injury severity (American Spinal Injury Association [ASIA] Impairment Scale [AIS]), and ventilation status. The odds of dying 50 days post-surgery are six times higher for patients ≥77 years of age versus those 65–76 years of age, five times higher for those with AIS A versus those with AIS B/C/D, and seven times higher for those who are ventilator dependent. An expected probability of dying within 50 days post-surgery was determined using these results. In-hospital mortality in the elderly after tSCI is high. The trend with age and time to death and the significant predictors of mortality identified in this study can be used to inform clinical decision making and discussions with patients and their families.

Comparison of the characteristics of work-related injuries between older workers and the workers of the conventional working-age in the Republic of Korea, 2010-2014

OBJECTIVE

With population ageing, the number of older workers is increasing and the number of work-related injuries in older people is also increasing. Occupational patterns and work-related injury patterns vary with age. This study aimed to compare the incidence and characteristics of work-related injuries in older and younger workers in Korea.

METHODS

We conducted a retrospective review of the characteristics of workers hospitalised with work-related injuries from January 2010 to December 2014, using data from the National Hospital Discharge In-Depth Injury Survey in South Korea. The analysis was stratified by age into older (aged ≥65 years) and younger (aged 20-64 years) workers.

RESULTS

The hospitalisation rate in older workers was double that of younger workers (2014 IRR: 2.06, 95% CI 1.53 to 2.76). Compared with workers of conventional working-age, a higher proportion of injured older workers were female (33.1% vs 13.6%, p<0.001), injured due to falls (40.8% vs 28.5%) and injured while working on a farm (46.5% vs 6.3%, p<0.001). In older workers, work-related injuries were seasonal and peaked during summer, but there was little seasonality in injuries among younger workers.

CONCLUSION

Older workers are more vulnerable to work-related injuries and have a different profile of work-related injuries from younger workers. Age-related differences in the injury profile need to be considered when developing workplace injury prevention policies and programmes, and the specific vulnerabilities of older workers need to be addressed.

The association between the etiology of a spinal cord injury and time to mortality in the United States: A 44-year investigation

Objective: To determine the association between spinal cord injury (SCI) etiology categories and mortality, and examine the association between etiology sub-categories and mortality. Design: Prospective cohort study. Setting: Model Systems and Shriners Hospital SCI units. Participants: Data were analyzed from 42,627 cases in the SCI Model System Collaborative Survival Study Database from 1973 to 2017. Those with SCI etiologies categorized as vehicular, violent, sports, falls, pedestrian, and medical were included. Interventions: Not applicable. Outcome Measure: Time to mortality after SCI. Results: Relative to the sports related etiology category, those with medical, pedestrian, violence, falls, and vehicular related SCIs had a 2.00 (95% confidence intervals (CIs): 1.79-2.24), 1.57 (CIs: 1.34-1.83), 1.54 (CIs: 1.41-1.68), 1.35 (CIs: 1.25-1.45), and 1.26 (CIs: 1.17-1.35) higher hazard for mortality, respectfully. Persons with SCIs from automobile crashes had a 1.38 (CIs: 1.23-1.56) higher hazard for mortality, whereas those with SCIs from motorcycle crashes had a 1.21 (CIs: 1.04-1.39) higher hazard for mortality, relative to other etiologies within the vehicular category. Those with SCIs from diving had a 1.37 (CIs: 1.18-1.59) higher hazard for mortality relative to other etiologies within the sports category. Conclusions: Injury etiology categories and certain sub-categories were associated with a higher risk for early mortality. Understanding how additional factors such as socioeconomic status, co-occurring injuries, medical co-morbidities, and environmental aspects interact with SCI etiologies may provide insights for how etiology of injury impacts survival. These findings may serve as a development for extending long-term life expectancy by informing SCI prevention programs and care post-injury.

Factors Impacting Mortality in Geriatric Patients with Acute Spine Fractures: A 12-Year Study of 613 Patients in Singapore

Study Design

Retrospective database analysis.

Purpose

To identify risk factors that predict mortality following acute spine fractures in geriatric patients of Singapore.

Overview of Literature

Acute geriatric spinal fractures contribute significantly to local healthcare costs and hospital admissions. However, geriatric mortality following acute spine fractures is scarcely assessed in the Asian population.

Methods

Electronic records of 3,010 patients who presented to our hospital’s emergency department and who were subsequently admitted during 2004–2015 with alleged history of traumatic spine fractures were retrospectively reviewed, and 613 patients (mean age, 85.7±4.5 years; range, 80–101 years; men, 108; women, 505) were shortlisted. Mortality rates were reviewed up to 1 year after admission and multivariate analyses were performed to identify independent risk factors correlating with mortality.

Results

Women were more susceptible to spine fractures (82.4%), with falls (77.8%) being the most common mechanism of injury. Mortality rates were 6.0%, 8.2%, and 10.4% at 3, 6, and 12 months, respectively. The most common causes of death at all 3 time points were pneumonia and ischemic heart disease. Based on the multivariate analysis at 1-year follow-up, elderly women had a lower mortality rate compared to men (p<0.001); mortality rates increased by 6.3% (p=0.024) for every 1-year increase in the patient’s age; and patients with an American Spinal Injury Association (ASIA) score of A–C had a much higher mortality rate compared to those with an ASIA score of D–E (p<0.001).

Conclusions

An older age at presentation, male sex, and an ASIA score of A–C were identified as independent factors predicting increased mortality among geriatric patients who sustained acute spine fractures. The study findings highlight at-risk groups for acute spine fractures, thereby providing an opportunity to develop strategies to increase the life expectancy of these patients.

Traumatic spinal cord injuries in geriatric population: etiology, management, and complications

Background

The relationship of traumatic spinal cord injury (SCI) and the geriatric population is not emphasized in current literature. Our objective was to evaluate mechanisms of injury, outcomes, and complications of geriatric patients with traumatic SCI.

Methods

Patients with traumatic spinal cord injuries admitted to the inpatient rehabilitation unit of a level I trauma center from 2003 to 2013 were reviewed. Inclusion criteria were ages ≥65 years old and availability of complete medical records. Patient demographics, mechanism of injury, diagnoses, American Spinal Injury Association (ASIA) grade, management (surgical, nonsurgical), complications, and mortality were evaluated.

Results

Seven hundred and fifty-seven SCI patients were identified and 53 met our inclusion criteria, with 35 (66.0%) males and 18 (34.0%) females. The average age was 74-years (range, 65 to 91 years). A proportion of 24.5% were 65-69 years of age, 30.2% were 70-74, 22.6% were 75-79, and 22.6% were 80 or older. Thirty-four (64.2%) underwent surgery. The two most common diagnoses of SCI were fractures (43.4%) and central cord syndrome (28.3%). ASIA grading was: A 5 (9.4%); B 3 (5.7%); C 5 (9.4%); D 40 (75.5%). The most severe SCI (ASIA score A and B) primarily occurred in the younger geriatric populations (ages 65-74), as did the highest rates of major complications or major and minor complications (15.4% and 46.2%, respectively, in the 65-69 group). Surgical management increased with age from 46.2% in the 65-69 group to 83.3% in the 75-79 group but subsequently decreased in the ≥80 group (66.7%).

Conclusions

Fractures and central cord syndrome were the most common diagnoses and typically due to falls. The complication rate in this population is high and due to complex causes. SCI in patients aged 65-69 was associated with increased rate of ASIA score A and increased rate of major complications.

Weekend versus Weekday Admission in Spinal Cord Injury and Its Effect on Timing of Surgical Intervention

OBJECTIVE

We sought to compare timing of intervention for patients with spinal cord injury (SCI) requiring surgical procedures during weekend versus weekday admissions.

METHODS

The National Inpatient Sample database from 2012 to 2014 was queried to identify patients with SCI who underwent surgical treatment (decompression with or without stabilization) as an emergent/urgent procedure. Timing of intervention, inpatient morbidity, and inpatient mortality were compared between patients admitted during the weekend versus a weekday. Multiple logistic regression analyses were also performed.

RESULTS

A total of 9390 patients were identified (mean age 55 years, 73.2% male) from the database, with 34.1% admitted during the weekend and 65.9% during a weekday. The average day of intervention for the entire cohort was 2.8 (SD 3.9, interquartile range 1-4); day 2.7 (standard deviation [SD] 4.0) versus day 2.8 ([SD] 3.9) for patients admitted in a weekend versus weekday (P = 0.418). After controlling for patient age, sex, and injury severity score on multiple logistic regression analysis, weekend admission was not significantly associated with early intervention (odds ratio [OR] 0.99; 95% confidence interval [CI], 0.82-1.21; P = 0.993), complication occurrence (OR 1.09; 95% CI, 0.86-1.38; P = 0.476), or inpatient mortality (OR 0.83; 95% CI, 0.44-1.56; P = 0.563). Patients with complete/American Spinal Injury Association A injuries were more likely to undergo early intervention (OR 2.09; 95% CI, 1.31-3.31; P = 0.002).

CONCLUSION

In this national study, patients with SCI who were admitted during the weekend received surgical intervention as early as patients admitted during a weekday. Furthermore, no differences in complication or mortality rates between groups were found.

Functional outcomes in geriatric patients with spinal cord injuries at a tertiary care rehabilitation hospital in Saudi Arabia

Study design

Retrospective study.

Objective

To identify demographic features, clinical characteristics, and complications associated with spinal cord injuries/disorders (SCI/D) among elderly individuals at a rehabilitation hospital and to measure the functional outcomes of rehabilitation.

Setting

Rehabilitation hospital in King Fahad Medical City (KFMC), Riyadh, Saudi Arabia.

Methods

The study was conducted in elderly individuals (aged ≥65 years) with SCI/D, admitted to an inpatient rehabilitation program between October 2014 and 2015. Demographic and clinical data were recorded along with functional independence measure (FIM) score at admission (FIMa) and discharge (FIMd). Data were descriptively analyzed. Association of non-metric and metric variables with complications was measured using χ², and Student's t-test, respectively.

Results

Twenty-four individuals with SCI/D (95.8% were male and retired) with mean (standard deviation, SD) age of 72.3 (6.3) years were included. The most common co-morbidities were hypertension (75.0%), and diabetes mellitus (58.3%). Degenerative cervical myelopathy (33.3%) was the most common cause of SCD. Of all, nine (37.5%) individuals had clinical complications (urinary tract infection(UTI); 8/9, surgical wound infection; 1/9). Mean (SD) hospitalization period during inpatient rehabilitation was 66.0 (13.9) days. Mean (SD) FIMa scores improved from 71.7 (17.3) to 85.3 (16.8) at discharge. Co-morbidities associated with complications were peripheral vascular disease, ischemic heart disease, and stroke.

Conclusion

In Saudi Arabia, non-traumatic spinal etiologies are the most frequent cause of spinal cord dysfunction in the elderly. Male gender, hypertension, and diabetes mellitus were high-risk factors among the geriatric age group with SCI/D. Elderly individuals with SCI/D without complications can have a shorter hospitalization period and higher functional gains during rehabilitation.

Spinal cord injury in elderly patients admitted to a tertiary hospital

BACKGROUND

Spinal cord injury (SCI) has a negative impact on quality of life and healthcare costs. In recent years with the age pyramid inversion, there has been a high prevalence of SCI in the elderly. These patients must be studied in order to invest in the prevention and treatment of SCI in these patients.

OBJECTIVE

To identify the characteristics and clinical aspects of spinal cord injury (SCI) in the elderly.

METHODS

Retrospective study of elderly patients (≥ 60 years of age) with a clinical diagnosis of SCI. Clinical and socio-demographic variables were collected from medical records.

RESULTS

Sixty-two elderly patients were studied (56% men). The patients were analyzed according to gender. Women presented compression fractures associated with thoracolumbar transition, while men presented with listhesis associated with cervical lesions and increased complications. It was found that the need for surgical intervention was higher in men. Among many characteristics that differed between the elderly and younger people (< 60 years; n = 259), in the morphological diagnosis, we observed that compression fractures and dislocation fractures were more highly associated with ages ≥ 60 and < 60, respectively. After SCI, the elderly have a higher risk for late hemodynamic instability.

CONCLUSION

Elderly individuals with SCI have distinct characteristics and clinical factors related to gender and age.

Age-specific characterization of spinal cord injuries over a 19-year period at a Japanese rehabilitation center

Regional demographics of spinal cord injuries (SCIs) are fundamental to identifying and implementing appropriate preventive measures. The current study was conducted as a longitudinal analysis of all patients with SCIs admitted to the Hyogo Rehabilitation Center over a 19-year period. The sex and age of the patient, time and nature of injury (i.e., cause, level, and extent), and period from injury to admission were evaluated retrospectively. Pertinent tests, including Poisson regression analysis, and the Cochran–Armitage, Kruskal–Wallis, and chi-square tests, were applied to assess demographic variables, with statistical significance set at p < 0.05. Between 1995 and 2013, a total of 632 patients with SCIs (predominantly male and largely < 60 years old) were admitted to our center for rehabilitation. Although the male: female ratio remained unchanged throughout the study period, the ratio of older adults increased over time. In assessing the cause of injury, the majority of the patients involved in road traffic accidents were aged ≤ 44 years, whereas patients aged ≥ 45 years accounted for the majority of low-distance falls and disease-related SCIs, the proportions of which gradually increased. Complete paralysis and paraplegia primarily occurred in patients aged ≤ 44 years, whereas the majority of incomplete injuries and tetraplegia were limited to those aged ≥ 45 years. The patient age at the time of SCI and the nature of the injury sustained were interrelated. Age-specific strategies thus offered the best means of preventing/reducing the incidence of SCIs in Hyogo prefecture.

Descriptive epidemiology of traumatic spinal injury in Japan

BACKGROUND

Spine injury epidemiology in Japan has not been studied since the 1990s when its incidence was 39.4-40.2 per million and the major cause of injury was motor vehicle crashes. We elucidate the current epidemiological state of spinal injury and spinal injury patients in Japan for the clinicians and public health prevention programs.

METHODS

Spine injury patients were retrospectively selected from the Japan Trauma Data Bank (JTDB) from 2004 to 2013 for all ages and all spinal injuries. The Abbreviated Injury Scale codes (AIS98) were translated into injuries. The dataset was contributed by 241 hospitals nationwide. The data was analysed for the causes of spinal injury, injury severity, age, gender differences, injury types, survival, anatomic location, circumstances of injury and medical history.

RESULTS

A total of 25,792 (M, 70.1%, F, 29.9%, mean age: 53.4 years) spinal injury patients were recorded in the JTDB from 2004 to 2013, when multiple injuries were included the number of cases swelled to 33,892 (M, 70.4%, F, 29.6%). The number of patients with spinal injuries as a percentage of all traumatic patients in the JTDB was observed to increase from 2004 (15.4%) to 2013 (17.6%). The aetiology of the injuries was mostly falls (52.4%) and motor vehicle crashes (39.8%). Most injuries occurred at the cervical spine level (49.7%). Medical histories of cardiovascular diseases were found, due mostly to hypertension (19.6%). In total, most of the injuries were associated with fractures (64.8%) and others (30.7%) involved the spinal cord. Suicides (12.0%) and industrial accidents (9.0%) caused spine injury were uniquely prevalent in the population.

CONCLUSION

The number of spine injuries has increased in the JTDB between 2004 and 2013. Motor vehicle crashes have been replaced by falls due to various causes as the leading cause of spine injury. Suicides and industrial accidents are becoming a burden. More studies are needed to verify the actual incidence.

Traumatic and Nontraumatic Spinal Cord Injuries

OBJECTIVE

Owing to the aging of the population in the United States, it is anticipated that injury mechanisms, treatment, and outcomes of spinal cord injuries (SCI) will change. There is a scarcity of literature on nontraumatic SCI. Our goal in this study was to evaluate the causes, management, complications, and outcomes after SCI.

METHODS

In a retrospective review, patients with traumatic and nontraumatic SCI admitted to the inpatient rehabilitation unit at a level 1 trauma center from 2003 to 2013 were reviewed.

RESULTS

In all, 757 entries were identified, and 685 unique patients met our inclusion criteria; 17.4% were <35 years of age, 51.7% were 35 to 64 years of age, and 30.9% were at least 65 years old. The young adults had the highest proportion of fractures (60.5%) and subluxations (21.8%), whereas the oldest group had the highest rates of stenosis (35.4%), spondylotic myelopathy (16.5%), and cancer (15.1%). In SCI patients <35 years of age, 66.6% of injuries were caused by traumatic mechanisms of injury compared with 30.2% in the geriatric cohort. In the total of all SCI, 61.6% were nontraumatic. Surgical management was more prevalent with increasing age (58.8%, 73.7%, 82.1% from youngest to oldest group), as were overall rates of complications (58.6%, 59.4%, 66.7%). Mortality rates significantly increased with age (2.5%, 18.9%, 40.6% overall mortality rates in the 3 age groups). The overall mortality rate in nontraumatic SCI patients was 27.7% compared with 14.8% in traumatic SCI patients.

CONCLUSIONS

Falls caused significantly more SCIs than expected, but most SCIs were predominantly nontraumatic in cause. The epidemiology of SCI is shifting rapidly.

Emergency Neurological Life Support: Traumatic Spine Injury

Traumatic spine injuries (TSIs) carry significantly high risks of morbidity, mortality, and exorbitant health care costs from associated medical needs following injury. For these reasons, TSI was chosen as an ENLS protocol. This article offers a comprehensive review on the management of spinal column injuries using the best available evidence. Alhough the review focuses primarily on cervical spinal column injuries, thoracolumbar injuries are briefly discussed as well. The initial emergency department clinical evaluation of possible spinal fractures and cord injuries, along with the definitive early management of confirmed injuries, is also covered.

[Traumatic spinal cord injury in people over 65 in Asturias]

AIMS

to assess incidence, causes and socio-demographicaspects of traumatic spinal cord injury among patients over 65 in Asturias (Spain).

PATIENTS AND METHODS

A census was performed between 1951 and 2013 of patients in Asturias, over 65 years-old coded as «traumatic spinal cord injury with or without vertebral fracture». Socio-demographic, hospital and clinical variables were recorded.

RESULTS

In total 180 patients were registered, most of them males (60%), with a mean age of 73 years (maximum 91). The estimated incidence in 2010 was found to be 24.9, in 2011, 28.9 and in 2012, 32.9 cases/million/year. The distribution in the type of injury was homogeneous and location in the cervical spine (40%) was found to be more common. There was bone injury in 71.4%, with multilevel injury in more than half of the cases. The main cause was accidental fall (52.1%), mainly at own height (68.6%), and most of them located in the cervical spine (38.5%), followed by traffic accidents with 57.6% located in the cervical spine.

CONCLUSIONS

A change was observed in the epidemiological profile of the patients over 65 years old with spinal cord injury. There were more cases associated with accidental fall. It is necessary to create specific preventive and therapeutic strategies for this group.

Spinal cord injury in older population in Turkey

STUDY DESIGN

Retrospective, comparative 4-year study.

OBJECTIVES

To identify the clinical characteristics unique to older patients with spinal cord injury (SCI).

SETTING

Turkish Armed Forces Rehabilitation Center, Ankara, Turkey.

METHODS

The study included 870 consecutive patients with SCI that were divided into two groups according to age. Patients aged ⩾60 years at the time of injury constituted the study group, and randomly selected patients aged <60 years that were matched for gender, week of admission and time since injury constituted the control group. Patients' demographic and clinical characteristics were recorded, compared and analyzed.

RESULTS

The study group included 73 SCI patients (mean age: 66.98±6.28 years) and the control group included 75 SCI patients (mean age: 33.93±10.67 years). Among the 148 patients, 98 (66.2%) were male. The vast majority of lesions were at the thoracic level (47.3%). In the older group, falls were the most frequent etiology (32.9%), simple falls predominated (62.5%). 49.3% of the study group vs 18.6% of the control group had a non-traumatic cause of SCI. Older patients were found to be less likely to have complete injury (27.4 vs 44%, P=0.035). The most common bladder management method was intermittent catheterization (69.6%) and the number of patients in each group treated with this method did not differ significantly (P>0.05). More patients in the study group had neuropathic pain (50.7 vs 34.7%, P=0.049) and abnormal urinary ultrasound findings (23.3 vs 9.3%, P=0.021).

CONCLUSION

RESULTS revealed that older patients with SCI may have different demographic and clinical features compared with younger patients.

The changing epidemiology of spinal trauma: a 13-year review from a Level I trauma centre

INTRODUCTION

Spinal injuries secondary to trauma are a major cause of patient morbidity and a source of significant health care expenditure. Increases in traffic safety standards and improved health care resources may have changed the characteristics and incidence of spinal injury. The purpose of this study was to review a single metropolitan Level I trauma centre's experience to assess the changing characteristics and incidence of traumatic spinal injuries and spinal cord injuries (SCI) over a 13-year period.

PATIENTS AND METHODS

A retrospective review of patients admitted to a Level I trauma centre between 1996 and 2008 was performed. Patients with spinal fractures and SCI were identified. Demographics, mechanism of injury, level of spinal injury and Injury Severity Score (ISS) were extracted. The outcomes assessed were the incidence rate of SCI and in-hospital mortality.

RESULTS

Over the 13-year period, 5.8% of all trauma patients suffered spinal fractures, with 21.7% of patients with spinal injuries having SCI. Motor vehicle accidents (MVAs) were responsible for the majority of spinal injuries (32.6%). The mortality rate due to spinal injury decreased significantly over the study period despite a constant mean ISS. The incidence rate of SCI also decreased over the years, which was paralleled by a significant reduction in MVA associated SCI (from 23.5% in 1996 to 14.3% in 2001 to 6.7% in 2008). With increasing age there was an increase in spinal injuries; frequency of blunt SCI; and injuries at multiple spinal levels.

CONCLUSION

This study demonstrated a reduction in mortality attributable to spinal injury. There has been a marked reduction in SCI due to MVAs, which may be related to improvements in motor vehicle safety and traffic regulations. The elderly population was more likely to suffer SCI, especially by blunt injury, and at multiple levels. Underlying reasons may be anatomical, physiological or mechanism related.

Spinal cord clinical trials and the role for bioengineering

There is considerable need for bringing effective therapies for spinal cord injury (SCI) to the clinic. Excellent medical and surgical management has mitigated poor prognoses after SCI; however, few advances have been made to return lost function. Bioengineering approaches have shown great promise in preclinical rodent models, yet there remains a large translational gap to carry these forward in human trials. Herein, we provide a framework of human clinical trials, an overview of past trials for SCI, as well as bioengineered approaches that include: directly applied pharmacologics, cellular transplantation, biomaterials and functional neurorehabilitation. Success of novel therapies will require the correct application of comprehensive preclinical studies with well-designed and expertly conducted human clinical trials. While biologics and bioengineered strategies are widely considered to represent the high potential benefits for those who have sustained a spinal injury, few such therapies have been thoroughly tested with appreciable efficacy for use in human SCI. With these considerations, we propose that bioengineered strategies are poised to enter clinical trials.

Epidemiology of traumatic spinal cord injuries in Iceland from 1975 to 2009

STUDY DESIGN

Retrospective population-based epidemiological study.

OBJECTIVES

To assess the nationwide, population-based incidence, causes, age, gender, extent and prevalence of spinal cord injuries (SCIs) in Iceland from 1975 to 2009.

SETTING

Landspitali University Hospital in Iceland, the single referral center for SCIs in Iceland.

METHODS

A retrospective review of hospital records on all admissions due to SCIs. Analysis of incidence, causes, age, gender, extent of injury and prevalence.

RESULTS

A total of 207 patients with traumatic spinal cord injury (TSCI) were admitted: males 72%, females 28%. The percentage of females with TSCI increased to 37% in 2000-2004. Mean age at injury was 38 years. Average incidence per million population per year was 30 in 1975-1979, 12.5 in 1995-1999 and 33.5 in 2005-2009. Thirty-day mortality was 6.3%. Causes of injury were road traffic accidents (RTA) in 42.5% of the cases; the majority did not use seatbelts. Falls amounted to 30.9%, with an increase of low falls among the elderly causing incomplete cervical lesions. Sport/leisure activities were the cause in 18.8%, of which 54% occurred after 2000. The main single cause of TSCI in sport/leisure were horse-riding accidents, followed by winter sport accidents, especially among women. Other causes constituted 7.7%. The injury was complete in 39%; cervical lesions were 57% and thoracic/lumbar lesions were 43%. In December 2009, the crude prevalence rate was 526 per million population.

CONCLUSIONS

The findings showed a significant increase of TSCI in 2005-2009, especially in sport/leisure accidents and incomplete cervical lesions due to falls among elderly. Prevention strategies need to focus on these risk groups and on seatbelt use.

A 50-year follow-up of the incidence of traumatic spinal cord injuries in Western Norway

STUDY DESIGN

Retrospective population-based epidemiological study.

OBJECTIVE

To assess the prevalence and temporal trends in the incidence of traumatic spinal cord injuries (TSCI), and demographic and clinical characteristics of an unselected, geographically defined cohort in the period 1952-2001.

METHODS

The patients were identified from hospital records. Crude rates and age-adjusted rates were calculated for each year. The multivariate relationship between cause of injury, age at injury, decade of injury and gender was examined using a Poisson regression model.

RESULTS

Of 336 patients, 199 patients were alive on 1 January 2002, giving a total prevalence of 36.5 per 100,000 inhabitants. The average annual incidence increased from 5.9 per million in the first decade to 21.2 per million in the last. Mean age at injury was 42.9 years and the male to female ratio 4.7:1. Fall was the most common cause of injury (45.5%), followed by motor vehicle accidents (MVA) (34.2%). The incidence of MVA-related injuries increased during the observation period, especially among men <30 years. The lesion level was cervical in 52.4%, thoracic in 29.5% and lumbar/sacral in 18.2%. The lesion was clinically incomplete in 58.6% and complete in 41.4%. The incidence of fall-related injuries and the proportion of incomplete cervical lesions increased during the observation period, especially among men >60 years.

CONCLUSIONS

The incidence of TSCI has increased during the past 50 years. Falls and MVA are potentially preventable causes. The increasing proportion of older patients with cervical lesions poses a challenge to the health system.
