Epidemiology of Spinal Trauma and Related Complication.

BACKGROUND: Traumatic spinal injury is leading cause of mortality and morbidity among the people of productive age group. This study aim to find the cause of spinal injury, site ,and mode of injury, treatment option given so that a preventive measures and create awareness among people of this region. METHODS: This is a prospective observation study done in Karnali Academy of Health Sciences from December 2021 to January 2023. Performa was filled to collect data. Data were entered in excel sheet and transported to SPSS 16.0 and statistical analysis was done . RESULTS: Out of 117 patients male population had higher incidence of spinal trauma (69.2%) with average age 43.9 years . Fall injury was the commonest mode of injury. 65.8% had injury at the thoracolumbar junction followed by lumbar, thoracic and cervical respectively. Cervical injury patients had higher incidence of neurological deficit. The average duration of trauma to hospital presentation was 10.9±11.2 hours. 19.7 % were operated and 6.8 % of patients were referred to other center. CONCLUSIONS: Fall injury being the commonest mode of injury in this art of world, prevention and awareness should be raised about the spinal trauma and its consequences. Adequate equipment with health facilities to the distant hospital may reduce the referral rate and duration of presentation to the hospital which ultimately prevent the further damage to the cord.

Cervical Collar-Associated Pressure Injury in Pediatric Trauma Patients: A Western Pediatric Surgery Research Consortium Study.

BACKGROUND: Healthcare-associated pressure injuries (HAPI) are known to be associated with medical devices and are preventable. Cervical spine immobilization is commonly utilized in injured children prior to clinical clearance or for treatment of an unstable cervical spinal injury. The frequency of HAPI has been quantified in adults with cervical spine immobilization but has not been well-described in children. The aim of this study was to describe characteristics of children who developed HAPI associated with cervical immobilization. METHODS: We analyzed a retrospective cohort of children (0-18 years) who developed a stage two or greater cervical HAPI. This cohort was drawn from an overall sample of 49,218 registry patients treated over a five-year period (2017-2021) at ten pediatric trauma centers. Patient demographics, injury characteristics, and cervical immobilization were tabulated to describe the population. RESULTS: The cohort included 32 children with stage two or greater cervical HAPI. The median age was 5 years (IQR 2-13) and 78% (n = 25) were admitted to the intensive care unit. The median (IQR) time to diagnosis of HAPI was 11 (7-21) days post-injury. The majority of cervical HAPI (78%, 25/32) occurred in children requiring immobilization for cervical injuries, with only four children developing HAPI after wearing a prophylactic cervical collar in the absence of a cervical spine injury. CONCLUSION: Advanced-stage HAPI associated with cervical collar use in pediatric trauma patients is rare and usually occurs in patients with cervical spine injuries requiring immobilization for treatment. More expedient cervical spine clearance with MRI is unlikely to substantially reduce cervical HAPI in injured children. LEVEL OF EVIDENCE: Level III (Epidemiologic and Prognostic).

Pediatric trauma population spine immobilization during resuscitation: A call for improved guidelines.

INTRODUCTION: This review aims to evaluate current practices regarding spine immobilization in pediatric trauma patients to evaluate their efficacy, reliability, and impact on clinical outcomes to guide future research and improved evidence-based practice guidelines. METHODS: PubMed, ProQuest, Embase, Google Scholar, and Cochrane were queried for studies pertaining to spinal immobilization practices in pediatric trauma patients. Articles were separated into studies that explored both the efficacy and clinical outcomes of spine immobilization. Outcomes evaluated included frequency of spinal imaging, self-reported pain level, emergency department length of stay (ED-LOS), and ED disposition. RESULTS: Six articles were included, with two studies examining clinical outcomes and 4 studies evaluating the efficacy and reliability of immobilization techniques. Immobilized children were significantly more likely to undergo cervical spine imaging (OR 8.2, p < 0.001), be admitted to the floor (OR 4.0, p < 0.001), be taken to the ICU or OR (OR 5.3, p < 0.05) and reported a higher median pain score. Older children were significantly more likely to be immobilized. No immobilization techniques consistently achieved neutral positioning, and patients most often presented in a flexed position. Lapses in immobilization occurred in 71.4% of patients. CONCLUSION: Immobilized pediatric patients underwent more cervical radiographs, and had higher hospital and ICU admission rates, and higher mean pain scores than those without immobilization. Immobilization was inconsistent across age groups and often resulted in lapses and improper alignment. Further research is needed to identify the most appropriate immobilization techniques for pediatric patients and when to use them.

Are severity and location of facial trauma risk factors for cervical spine injuries? 10-year analysis based on the use of the AO spine injury classification and the comprehensive facial injury (CFI) score.

PURPOSE: This study aims to demonstrate a correlation between cervical spine injury and location and severity of facial trauma. METHODS: We did a 10-year retrospective analysis of prospectively collected patients with at least one facial and/or cervical spine injury. We classified facial injuries using the Comprehensive Facial Injury (CFI) score, and stratified patients into mild (CFI < 4), moderate (4 ≤ CFI < 10) and severe facial trauma (CFI ≥ 10). The primary outcome was to recognize the severity and topography of the facial trauma which predict the probability of associated cervical spine injuries. RESULTS: We included 1197 patients: 78% with facial injuries, 16% with spine injuries and 6% with both. According to the CFI score, 48% of patients sustained a mild facial trauma, 35% a moderate one and 17% a severe one. The midface was involved in 45% of cases, then the upper facial third (13%) and the lower one (10%). The multivariate analysis showed multiple independent risk factors for associated facial and cervical spine injuries, among them an injury of the middle facial third (OR 1.11 p 0.004) and the facial trauma severity, having every increasing point of CFI score a 6% increasing risk (OR 1.06 p 0.004). CONCLUSIONS: Facial trauma is a risk factor for a concomitant cervical spine injury. Among multiple risk factors, severe midfacial trauma is an important red flag. The stratification of facial injuries based on the CFI score through CT-scan images could be a turning point in the management of patients at risk for cervical spine injuries before imaging is available.

Pelvis-Sacrum-Lumbar Spine Injury Characteristics From Underbody Blast Loading.

INTRODUCTION: Combat-related injuries from improvised explosive devices occur commonly to the lower extremity and spine. As the underbody blast impact loading traverses from the seat to pelvis to spine, energy transfer occurs through deformations of the combined pelvis-sacrum-lumbar spine complex, and the time factor plays a role in injury to any of these components. Previous studies have largely ignored the role of the time variable in injuries, injury mechanisms, and warfighter tolerance. The objective of this study is to relate the time or temporal factor using a multi-component, pelvis-sacrum-lumbar spinal column complex model. MATERIALS AND METHODS: Intact pelvis-sacrum-spine specimens from pre-screened unembalmed human cadavers were prepared by fixing at the superior end of the lumbar spine, pelvis and abdominal contents were simulated, and a weight was added to the cranial end of the fixation to account for torso effective mass. Prepared specimens were placed on the platform of a custom vertical accelerator device and aligned in a seated soldier posture. An accelerometer was attached to the seat platen of the device to record the time duration to peak velocity. Radiographs and computed tomography images were used to document and associate injuries with time duration. RESULTS: The mean age, stature, weight, body mass index, and bone density of 12 male specimens were as follows: 65 ± 11 years, 1.8 ± 0.01 m, 83 ± 13 kg, 27 ± 5.0 kg/m2, and 114 ± 21 mg/cc. They were equally divided into short, medium, and long time durations: 4.8 ± 0.5, 16.3 ± 7.3, and 34.5 ± 7.5 ms. Most severe injuries associated with the short time duration were to pelvis, although they were to spine for the long time duration. CONCLUSIONS: With adequate time for the underbody blast loading to traverse the pelvis-sacrum-spine complex, distal structures are spared while proximal/spine structures sustain severe/unstable injuries. The time factor may have implications in seat and/or seat structure design in future military vehicles to advance warfighter safety.

Subaxial Cervical Spine Motion With Different Sizes of Head-supported Mass Under Accelerative Forces.

INTRODUCTION: The evolution of military helmet devices has increased the amount of head-supported mass (HSM) worn by warfighters. HSM has important implications for spine biomechanics, and yet, there is a paucity of studies that investigated the effects of differing HSM and accelerative profiles on spine biomechanics. The aim of this study is to investigate the segmental motions in the subaxial cervical spine with different sizes of HSM under Gx accelerative loading. METHODS: A three-dimensional finite element model of the male head-neck spinal column was used. Three different size military helmets were modeled and incorporated into head-neck model. The models were exercised under Gx accelerative loading by inputting low and high pulses to the cervical vertebra used in the experimental studies. Segmental motions were obtained and normalized with respect to the non-HSM case to quantify the effect of HSM. RESULTS: Segmental motions increased with an increase in velocity at all segments of the spine. Increasing helmet size resulted in larger motion increases. Angulations ranged from 0.9° to 9.3° at 1.8 m/s and from 1.3° to 10.3° at 2.6 m/s without a helmet. Helmet increased motion between 5% to 74% at 1.8 m/s. At 2.6 m/s, the helmet increased segmental motion anywhere from 10% to 105% in the subaxial cervical spine. The greatest motion was seen at the C5-C6 level, followed by the C6-C7 level. CONCLUSIONS: The subaxial cervical spine experiences motion increases at all levels at both velocity profiles with increasing HSM. Larger helmet and greater impact velocity increased motion at all levels, with C5-C6 demonstrating the largest range of motion. HSM should be minimized to reduce the risk of cervical spine injury to the warfighter.

Traumatic spinal injury-related hospitalizations in the United States, 2016-2019: a retrospective study.

BACKGROUND: Traumatic spinal injury (TSI) is associated with significant fatality and social burden; however, the epidemiology and treatment of patients with TSI in the US remain unclear. MATERIALS AND METHODS: An adult population was selected from the National Inpatient Sample database from 2016 to 2019. TSI incidence was calculated and TSI-related hospitalizations were divided into operative and nonoperative groups according to the treatments received. TSIs were classified as fracture, dislocation, internal organ injury, nerve root injury, or sprain injuries based on their nature. The annual percentage change (APC) was calculated to identify trends. In-hospital deaths were utilized to evaluate the prognosis of different TSIs. RESULTS: Overall, 95 047 adult patients were hospitalized with TSI in the US from 2016 to 2019, with an incidence rate of 48.4 per 100 000 persons in 2019 (95% CI: 46.2-50.6). The total incidence increased with an APC of 1.5% (95% CI: 0.1-3%) from 2016 to 2019. Operative TSI treatment was more common than nonoperative (32.8 vs. 3.8; 95% CI: 32.3-33.2 vs. 3.6-4%). The number of operations increased from 37 555 (95% CI: 34 674-40 436) to 40 460 (95% CI: 37 372-43 548); however, the operative rate only increased for internal organ injury (i.e. spinal cord injury [SCI])-related hospitalizations (APC, 3.6%; 95% CI: 2.8-4.4%). In-hospital mortality was highest among SCI-related hospitalizations, recorded at 3.9% (95% CI: 2.9-5%) and 28% (95% CI: 17.9-38.2%) in the operative and nonoperative groups, respectively. CONCLUSIONS: The estimated incidence of TSI in US adults increased from 2016 to 2019. The number of operations increased; however, the proportion of operations performed on TSI-related hospitalizations did not significantly change. In 2019, SCI was the highest associated mortality TSI, regardless of operative or nonoperative treatment.

Pediatric Cervical Spine Injury Following Blunt Trauma in Children Younger Than 3 Years: The PEDSPINE II Study.

Importance: There is variability in practice and imaging usage to diagnose cervical spine injury (CSI) following blunt trauma in pediatric patients. Objective: To develop a prediction model to guide imaging usage and to identify trends in imaging and to evaluate the PEDSPINE model. Design, Setting, and Participants: This cohort study included pediatric patients (<3 years years) following blunt trauma between January 2007 and July 2017. Of 22 centers in PEDSPINE, 15 centers, comprising level 1 and 2 stand-alone pediatric hospitals, level 1 and 2 pediatric hospitals within an adult hospital, and level 1 adult hospitals, were included. Patients who died prior to obtaining cervical spine imaging were excluded. Descriptive analysis was performed to describe the population, use of imaging, and injury patterns. PEDSPINE model validation was performed. A new algorithm was derived using clinical criteria and formulation of a multiclass classification problem. Analysis took place from January to October 2022. Exposure: Blunt trauma. Main Outcomes and Measures: Primary outcome was CSI. The primary and secondary objectives were predetermined. Results: The current study, PEDSPINE II, included 9389 patients, of which 128 (1.36%) had CSI, twice the rate in PEDSPINE (0.66%). The mean (SD) age was 1.3 (0.9) years; and 70 patients (54.7%) were male. Overall, 7113 children (80%) underwent cervical spine imaging, compared with 7882 (63%) in PEDSPINE. Several candidate models were fitted for the multiclass classification problem. After comparative analysis, the multinomial regression model was chosen with one-vs-rest area under the curve (AUC) of 0.903 (95% CI, 0.836-0.943) and was able to discriminate between bony and ligamentous injury. PEDSPINE and PEDSPINE II models' ability to identify CSI were compared. In predicting the presence of any injury, PEDSPINE II obtained a one-vs-rest AUC of 0.885 (95% CI, 0.804-0.934), outperforming the PEDSPINE score (AUC, 0.845; 95% CI, 0.769-0.915). Conclusion and Relevance: This study found wide clinical variability in the evaluation of pediatric trauma patients with increased use of cervical spine imaging. This has implications of increased cost, increased radiation exposure, and a potential for overdiagnosis. This prediction tool could help to decrease the use of imaging, aid in clinical decision-making, and decrease hospital resource use and cost.

Characteristics of work-related spine injury in the USA: a National Trauma Data Bank analysis.

PURPOSE: Workplace injury is a commonplace occurrence in the USA. Spine injuries are especially devastating as they can cause chronic pain and limit mobility which prevents patients from returning to work. Gaining a better understanding of the patients, mechanisms, and treatments associated with these injuries can aid in improving outcomes. The purpose of this study is to characterize the nature of work-related spine injuries. METHODS: The National Trauma Data Bank was queried from 2017 to 2019 for all diagnoses involving the cervical, thoracic, lumbar, and sacral spine. Patient demographics, comorbidities, injury characteristics, spinal diagnoses, and procedures were identified for each occupation. Occupational industries, patient demographics, mechanisms of injury, diagnoses, and spinal procedures were characterized. RESULTS: A total of 100,842 work-related injuries were identified between 2017 and 2019. Of those, 19,002 (19%) were spine injuries, and subsequently, 3963 (21%) required spinal surgery. Eight thousand twenty-nine (42%) cases were seen among construction workers, which had the highest proportion of Hispanic patients (36%). Smoking was prevalent in labor-intensive occupations with high rates of spine injury such as building and grounds maintenance. The most common mechanism of injury was a fall from a roof. The most common injury diagnoses were L1, L2, and L3 fractures, and the most common procedures were T12-L1 fusion, multilevel thoracic fusion, and multilevel lumbar fusion. CONCLUSION: Spine injuries represent a significant portion of work-related injuries in the USA and a considerable portion require neurosurgical intervention. Initial efforts should focus on the prevention and management of lumbar spine injuries in the construction industry.

Cervical spine trauma.

Cervical spine trauma encompasses a wide of injuries, ranging from stable, minor lesions to unstable, complex lesions that can lead to neurologic sequelae or vascular involvement. The Canadian C-Spine Rule and the NEXUS criteria aim to identify individuals with a low risk of cervical spine trauma who can safely forgo imaging tests. In high-risk patients, an imaging test is indicated. In adult patients the imaging test of choice is multidetector computed tomography. Complementary imaging tests such as CT angiography of the supra-aortic vessels and/or magnetic resonance imaging are occasionally necessary. It can be challenging for radiologists to diagnose and classify these lesions, because some of them can be subtle and difficult to detect. This paper aims to describe the most important imaging findings and the most widely used classification systems.

Spinal injury rates and specific causation in motor vehicle collisions.

Motor vehicle collisions (MVCs) are a leading cause of acute spinal injuries. Chronic spinal pathologies are common in the population. Thus, determining the incidence of different types of spinal injuries due to MVCs and understanding biomechanical mechanism of these injuries is important for distinguishing acute injuries from chronic degenerative disease. This paper describes methods for determining causation of spinal pathologies from MVCs based on rates of injury and analysis of the biomechanics require to produce these injuries. Rates of spinal injuries in MVCs were determined using two distinct methodologies and interpreted using a focused review of salient biomechanical literature. One methodology used incidence data from the Nationwide Emergency Department Sample and exposure data from the Crash Report Sample System supplemented with a telephone survey to estimate total national exposure to MVC. The other used incidence and exposure data from the Crash Investigation Sampling System. Linking the clinical and biomechanical findings yielded several conclusions. First, spinal injuries caused by an MVC are relatively rare (511 injured occupants per 10,000 exposed to an MVC), which is consistent with the biomechanical forces required to generate injury. Second, spinal injury rates increase as impact severity increases, and fractures are more common in higher-severity exposures. Third, the rate of sprain/strain in the cervical spine is greater than in the lumbar spine. Fourth, spinal disc injuries are extremely rare in MVCs (0.01 occupants per 10,000 exposed) and typically occur with concomitant trauma, which is consistent with the biomechanical findings 1) that disc herniations are fatigue injuries caused by cyclic loading, 2) the disc is almost never the first structure to be injured in impact loading unless it is highly flexed and compressed, and 3) that most crashes involve predominantly tensile loading in the spine, which does not cause isolated disc herniations. These biomechanical findings illustrate that determining causation when an MVC occupant presents with disc pathology must be based on the specifics of that presentation and the crash circumstances and, more broadly, that any causation determination must be informed by competent biomechanical analysis.

Hanging and Strangulation Injuries: An Institutional Review From a Level 1 Pediatric Trauma Center.

BACKGROUND: We sought to define the incidence and outcomes of pediatric hanging and strangulation injuries to inform best practices for trauma triage and management. METHODS: A retrospective review was conducted that included all patients who presented after hanging or strangulation to a Level I Pediatric Trauma Center from 2011 through 2021. Patient demographics, injury characteristics, and clinical outcomes were collected. All imaging modalities of the head and neck were reviewed to determine if a bony fracture or vascular injury was present. RESULTS: Over the 11-year study period, 128 patients met inclusion criteria. The median age of the cohort was 13 years [IQR: 8.5-15], most patients were male (60.9%), and the median GCS was 11 [3, 15]. There were 96 cases (75%) that were intentional injuries. 76 patients (59.4%) received imaging in the form of plain radiographs, CT, or MRI of the neck and cervical spine. No fractures were identified and there were 0 clinically significant cervical spine injuries. CT angiograms of the neck identified no cerebral vascular injuries. Mortality was high (32%), and 25% of patients with nonaccidental injuries had a documented prior suicide attempt. CONCLUSION: We identified no cervical spine fractures and no blunt cerebral vascular injuries after a hanging or strangulation in over 10 years at a Level 1 Pediatric Trauma Center. Use of CT and CT angiography of the neck and cervical spine should be minimized in this patient population without high clinical index of suspicion and/or significant mechanism. LEVEL OF EVIDENCE: IV.

Cervical spine injuries in adults ≥ 65 years after low-level falls - A systematic review and meta-analysis.

BACKGROUND: Adults ≥ 65 are at risk of cervical spine (C-spine) injury, even after low-level falls. The objectives of this systematic review were to determine the prevalence of C-spine injury in this population and explore the association of unreliable clinical exam with C-spine injury. METHODS: We conducted this systematic review according to PRISMA guidelines. We searched MEDLINE, PubMed, EMBASE, Scopus, Web of Science, and the Cochrane Database of Systematic reviews to include studies reporting on C-spine injury in adults ≥ 65 years after low-level falls. Two reviewers independently screened articles, abstracted data, and assessed bias. Discrepancies were resolved by a third reviewer. A meta-analysis was performed to estimate overall prevalence and the pooled odds ratio for the association between C-spine injury and an unreliable clinical exam. RESULTS: The search identified 2044citations, 138 full texts were screened, and 21 studies were included in the systematic review. C-spine injury prevalence in adults ≥ 65 years after low-level falls was 3.8% (95% CI: 2.8-5.3). The odds of c-spine injury in those with altered level of consciousness (aLOC) v/s not aLOC was 1.21 (0.90-1.63) and in those with GCS < 15 v/s GCS 15 was 1.62 (0.37-6.98). Studies were at a low-risk of bias, although some had low recruitment and significant loss to follow-up. CONCLUSIONS: Adults ≥ 65 years are at risk of cervical spine injury after low-level falls. More research is needed to determine whether there is an association between cervical spine injury and GCS < 15 or altered level of consciousness.

Incidence and pattern of traumatic spine injury in a single level I trauma center of southern Iran.

PURPOSE: Spine injury is one of the leading causes of death and mortality worldwide. The objective of this study was to determine the incidence, pattern and outcome of trauma patients with spine injury referred to the largest trauma center in southern Iran during the last 3 years. METHODS: This is a cross-sectional study conducted between March 2018 and June 2021 in the largest trauma center in the southern Iran. The data collection form included the age, sex, injury location (cervical, thoracic, and lumbar), cause of injury (traffic accidents, falls, and assaults), length of hospital stay, injured segment of spine injury, severity of injury, and outcome. Statistical analyzes were performed using SPSS software version 24. RESULTS: Totally 776 cases of spine injury were identified. The spine injury rate was 17.0%, and the mortality rate was 15.5%. Cervical spine injury (20.4%) more often occulted in motorcycle accident, and thoracic spine injury (20.1%) occulted in falls. The highest and lowest rates of spine injurys were related to lumbar spine injury (30.2%) and cervical spine injury (21.5%), respectively. There was a statistically significant relationship between the mechanism of injury and the location of spine injury (p < 0.001). And patients with lumbar spine injury had the highest mortality rate (16.7%). Injury severity score (OR= 1.041, p < 0.001) and length of stay (OR = 1.018, p < 0.001) were strong predictors of mortality in trauma patients with spine injury. CONCLUSION: The results of the study showed that the incidence of traumatic spine injury rate was approximately 17.0% in southern of Iran. Road traffic injury and falls are the common mechanism of injury to spine. It is important to improve the safety of roads, and passengers, as well as work environment, and improve the quality of cars. Also, paying attention to the pattern of spine injury may assist to prevent the missing diagnosis of spine injury in multiple trauma patients.

Litigation involving sports-related spinal injuries: a comprehensive review of reported legal claims in the United States in the past 70 years.

BACKGROUND CONTEXT: Sports-related spinal injuries can be catastrophic in nature. Athletes competing in collision sports (eg, football) may be particularly prone to injury given the high-impact nature of these activities. Due to the oftentimes profound impact of sports-related spinal injuries on health and quality-of-life, they are also associated with a substantial risk of litigation. However, no study to date has assessed litigation risks associated with sports-related spinal injuries. A better understanding of the risk factors surrounding these legal claims may provide insights into injury prevention and other strategies to minimize litigation risks. In addition, it may allow the spine surgeon to better recognize the health, socioeconomic, and legal challenges faced by this patient population. PURPOSE: To provide a comprehensive assessment of reported legal claims involving sports-related spinal injuries, including a comparative analysis of legal outcomes between collision and non-collision sports. To discuss strategies to prevent sports-related spinal injuries and minimize litigation risks. STUDY DESIGN/SETTING: Retrospective review. PATIENT SAMPLE: Athletes experiencing spinal injuries during sports. OUTCOME MEASURES: Outcomes included verdict outcome (defendant vs. plaintiff), legal claims, injuries sustained, clinical symptoms, and award payouts. METHODS: The legal research database Westlaw Edge (Thomson Reuters) was queried for legal claims brought in the United States from 1950 to 2021 involving sports-related spinal injuries. Verdict or settlement outcomes were collected as well as award payouts, time to case closure, case year, and case location. Demographic data, including type of sport (ie collision vs. non-collision sport) and level of play were obtained. Legal claims, spinal injuries sustained, and clinical symptoms were also extracted. Furthermore, the nature of injury, injured spinal region, and treatment pursued were collected. Descriptive statistics were reported for all cases and independent-samples t-tests and chi-square tests were used to compare differences between collision and non-collision sports. RESULTS: Of the 840 cases identified on initial search, 78 met our criteria for in-depth analysis. This yielded 62% (n=48) defendant verdicts, 32% (n=25) plaintiff verdicts, and 6% (n=5) settlements, with a median inflation-adjusted award of $780,000 (range: $5,480-$21,585,000) for all cases. The most common legal claim was negligent supervision (n=38, 46%), followed by premises liability (n=23, 28%), and workers' compensation/no fault litigation (n=10, 12%). The most common injuries sustained were vertebral fractures (n=34, 44%) followed by disc herniation (n=14, 18%). Most cases resulted in catastrophic neurological injury (n=37, 49%), either paraplegia (n=6, 8%) or quadriplegia (n=31, 41%), followed by chronic/refractory pain (n=32, 43%). Non-collision sport cases had a higher percentage of premises liability claims (41% vs. 11%, p=.006) and alleged chronic/refractory pain (53% vs. 28%, p=.04). Conversely, collision sport cases had a higher proportion of workers' compensation/no fault litigation (23% vs. 4%, p=.03) and cases involving disc herniation (29% vs. 9%, respectively; p=.04). CONCLUSION: Sports-related spinal injuries are associated with multiple and complex health, socioeconomic, and legal consequences, with median inflation-adjusted award payouts nearing $800,000 per case. In our cohort, the most commonly cited legal claims were negligent supervision and premises liability, emphasizing the need for prevention guidelines for safe sports practice, especially in non-professional settings. Cases involving athletes participating in non-collision sports were significantly associated with claims citing chronic/refractory pain, highlighting the importance of long-term care in severely injured athletes.

Differences in clinical characteristics of cervical spine injuries in older adults by external causes: a multicenter study of 1512 cases.

Although traumatic cervical spine injuries in older adults are commonly caused by minor traumas, such as ground-level falls, their prognosis is often unfavorable. Studies examining the clinical characteristics of cervical spine injuries in older adults according to the external cause of injury are lacking. This study included 1512 patients of ≥ 65 years of age with traumatic cervical spine injuries registered in a Japanese nationwide multicenter database. The relationship between the external causes and clinical characteristics, as well as factors causing unfavorable outcomes at the ground-level falls, were retrospectively reviewed and examined. When fall-induced cervical spine injuries were categorized and compared based on fall height, the patients' backgrounds and injury statuses differed significantly. Of note, patients injured from ground-level falls tended to have poorer pre-injury health conditions, such as medical comorbidities and frailty, compared with those who fell from higher heights. For ground-level falls, the mortality, walking independence, and home-discharge rates at 6 months post-injury were 9%, 67%, and 80%, respectively, with preexisting medical comorbidities and frailty associated with unfavorable outcomes, independent of age or severity of neurological impairment at the time of injury.

Cervical spine injuries occurring at the beach: epidemiology, mechanism of injury and risk factors.

OBJECTIVE: Surf zone injuries include cervical spine injuries (CSI). Risk factors for CSI have not been extensively investigated. The objective was to examine risk factors associated with diagnosed CSI that occurred in a beach setting. METHODS: This retrospective case series used manually linked data from Sunshine Coast Hospital and Health Service Emergency Departments, Queensland Ambulance Service, Surf Life Saving Queensland (SLSQ), and Bureau of Meteorology data from 01/01/2015-21/04/2021. Variables included victim demographics, mechanism of injury, scene information, and patient course. RESULTS: Seventy-nine of the 574 (13.8%) confirmed CSI occurred at the beach. Local residents and visitors were injured equally. Females represented a minority (12.7%) of those diagnosed with CSI but were a higher proportion of suspected spinal incidents reported to SLSQ (45%). Surfers were more likely to be injured through shallow water diving than swimmers (27.6% vs 2.2%). Females were more likely to be injured by shallow water diving than males (30.0% vs 8.7%). Visitors were more likely to be injured swimming and local residents surfing (68.2% vs 77.8% respectively). CSI occurred most commonly (40.0%) with a below average ocean wave height (0.75-1.25 m) and were most likely (45.3%) to occur in the second half of the outgoing tide. One beach had a statistically significant greater incidence of spinal incidents (OR 3.9, 95% CI: 2.1-7.2) and of CSI (OR 10.7, 95% CI: 1.5-79.5). CONCLUSIONS: Risk factors for CSI at the beach include male sex, smaller wave height and an outgoing tide. Shallow water diving among surfers and females should be addressed urgently.

Early Intervention of Cold-Water Swimming on Functional Recovery and Spinal Pain Modulation Following Brachial Plexus Avulsion in Rats.

Brachial plexus avulsion (BPA) causes peripheral nerve injury complications with motor and sensory dysfunction of the upper limb. Growing evidence has shown an active role played by cold-water swimming (CWS) in alleviating peripheral neuropathic pain and functional recovery. This study examined whether CWS could promote functional recovery and pain modulation through the reduction of neuroinflammation and microglial overactivation in dorsal horn neurons at the early-stage of BPA. After BPA surgery was performed on rats, they were assigned to CWS or sham training for 5 min twice a day for two weeks. Functional behavioral responses were tested before and after BPA surgery, and each week during training. Results after the two-week training program showed significant improvements in BPA-induced motor and sensory loss (p < 0.05), lower inflammatory cell infiltration, and vacuole formation in injured nerves among the BPA-CWS group. Moreover, BPA significantly increased the expression of SP and IBA1 in dorsal horn neurons (p < 0.05), whereas CWS prevented their overexpression in the BPA-CWS group. The present findings evidenced beneficial rehabilitative effects of CWS on functional recovery and pain modulation at early-stage BPA. The beneficial effects are partially related to inflammatory suppression and spinal modulation. The synergistic role of CWS combined with other management approaches merits further investigation.

Cervical spine injury response to direct rear head impact.

BACKGROUND: Direct rear head impact can occur during falls, road accidents, or sports accidents. They induce anterior shear, flexion and compression loads suspected to cause flexion-distraction injuries at the cervical spine. However, post-mortem human subject experiments mostly focus on sled impacts and not direct head impacts. METHODS: Six male cadavers were subjected to a direct rear head impact of 3.5 to 5.5 m/s with a 40 kg impactor. The subjects were equipped with accelerometers at the forehead, mouth and sternum. High-speed cameras and stereography were used to track head displacements. Head range of motion in flexion-extension was measured before and after impact for four cadavers. The injuries were assessed from CT scan images and dissection. FINDINGS: Maximum head rotation was between 43 degrees and 78 degrees, maximum cranial-caudal displacement between -12 mm and - 196 mm, and antero-posterior displacement between 90 mm and 139 mm during the impact. Four subjects had flexion-distraction injuries. Anterior vertebral osteophyte identification showed that fractures occurred at adjacent levels of osteophytic bridges. The other two subjects had no anterior osteophytes and suffered from C2 fracture, and one subject also had a C1-C2 subluxation. C6-C7 was the most frequently injured spinal level. INTERPRETATION: Anterior vertebral osteophytes appear to influence the type and position of injuries. Osteophytes would seem to provide stability in flexion for the osteoarthritic cervical spine, but to also lead to stress concentration in levels adjacent to the osteophytes. Clinical management of patients presenting with osteophytes fracture should include neck immobilization and careful follow-up to ensure bone healing.
