Spinal cord injury resulting from gunshot wounds: a comparative study with non-gunshot causes

Investigating Research Hotspots of Combat-related Spinal Injuries: A 30-year Bibliometric Analysis Study

INTRODUCTION

Spinal cord injuries often lead to significant motor and sensory deficits, as well as autonomic dysfunction. Compared with normal spinal injuries, combat-related spinal injuries (CRSIs) are usually more complex and challenging to treat because of multiple traumas, firing-line treatments, and arduous initial treatments on a battlefield. Yet numerous issues remain unresolved about clinical treatment and scientific research. The enhancement of CRSI diagnosis and treatment quality by military surgeons and nurses is imperative. The objective of this study is to identify the frontiers, hotspots, and trends among recent research, summarize the development process of clinical trials, and visualize them systematically.

MATERIALS AND METHODS

We collected publications from CRSI based on the Core Collection of Web of Science for 30 years from January 1, 1993 to May 1, 2023.Visualizations of the knowledge maps were produced using VOSviewer and CiteSpace software. We examined annual trends of publications and distribution patterns, the number of publications, as well as the research hotspots.

RESULTS

Among 201 documents, it was found that there was a stable upward trend in publications. There were 2 rapid growth stages during the 30 years. Among all countries, the USA contributed the most publications, along with the highest influence and the most international cooperation. Military Medicine was the journal of the maximum publications, whereas the Spine journal was the most influential one. Keyword co-occurrence analysis and trend topics analysis revealed that these articles focused 5 distinct categories for CRSI.

CONCLUSIONS

As the first bibliometric study focused on CRSI, we demonstrated the evolution of the field and provided future research directions. We summarized the hotspots and 5 clusters published. This would serve as a useful guide for clinicians and scientists regarding CRSI global impacts.

Timing of surgical intervention after firearm-related spinal cord injury

CONTEXT

Surgical management of firearm-related spinal cord injury (SCI) remains controversial, and there are no clear guidelines. Time to surgery, surgical indications, and patient characteristics on initial presentation in this group are not well understood, and these factors may impact the potential for neurologic recovery after operative intervention.

OBJECTIVE

To understand the timing and factors affecting the timing of operative intervention after firearm-related SCI.

METHODS

In a retrospective cohort study, patients with traumatic SCI from July 2012 to July 2022 (n = 1569) were identified from our level 1 trauma center Trauma Registry. Data was obtained from the trauma registry and chart review. Rates and timing of surgical intervention, initial injury severity measures, and general hospital outcomes were compared between firearm-related SCI and blunt trauma SCI.

RESULTS

Patients with firearm-related SCI were less likely to undergo surgery compared to other etiologies (24.3% vs. 70.2%, P < 0.0001). Time to surgery for firearm-related SCI was longer than for other etiologies (49.2 ± 92.9 vs. 30.6 h ± 46.0, P = 0.012). Multiple measures of initial injury severity, including Injury Severity Score, Glasgow Coma Score, and emergency department disposition demonstrated more severe injury among patients with firearm-related SCI, and these patients often required other emergent surgeries prior to spine surgery (52%).

CONCLUSIONS

There was a longer time to spine surgery among patients with firearm-related SCI compared to blunt trauma SCI, and patients with firearm-related SCI were more severely injured on initial presentation. Further research is needed to understand the complex relationship between patient injury severity, surgical intervention, surgical timing, and outcomes after firearm-related SCI.

Spinal Cord Injuries in Iraq: A Teleassessment Survey of the Survivors from 2017 to 2018 Islamic State of Iraq and Syria War

Introduction: The significance of comprehensive investigations specifically addressing the characteristics and implications of nervous system injuries (NSIs) and particularly war-related spinal cord injuries (SCI) remain limited. Iraq lacks comprehensive survey studies for quality of life for people after SCI. The objective of this work was to identify the number of NSIs and mortality of those injured during the Islamic State of Iraq and Syria (ISIS) war in Iraq and analyze events specifically as sociodemographic variables to assess quality of life healthy, psychological, and social disorders from onset of injury till the involving. Methods: A survey-based descriptive study, and analytical retrospective at community-based of Nineveh Governorate, in Iraq. The participants were 34 survivors of ISIS war with SCIs, ages between 9 and 60 years, and 7 females (20.59%) and 27 males (79.41%) as registered in Nineveh Center of Disability Rehabilitation. Data collection was conducted using Telephone Video Interviews and respondents' health information. Protocol-specific questions and some psychological and social scales (PTSD) (DSM-IV), (TAS-20), (SWLS), and (MSPSS) were also used. Results: There were 2,990 NSIs with the highest rate of injuries occurring from 2017 to 2018, and the SCIs were 267 injuries (8.93%), and (70.59%) at level T the mortalities were 57 cases, all participants suffered from physical and psychological chronic complications, while the results of the PTSD, GPC, and SWLS were at a moderate level. Conclusions: In urban warfare, there's a rise in NSIs, notably SCIs influenced by the type of weaponry. The survivors face significant physical, psychological, social, and financial burdens. More research is crucial to understanding their situations and developing strategies to alleviate their health, social, and financial challenges.

Civilian Ballistic Injuries to the Atlantoaxial Spine: A Single Institution Case Series

STUDY DESIGN

Retrospective case series.

OBJECTIVE

Describe the injury characteristics of ballistic fractures involving the atlantoaxial spine.

SUMMARY OF BACKGROUND DATA

Civilian gunshot wounds to the spine are an increasingly common injury in the United States. Civilian studies have focused on ballistic injuries to the entire spine as opposed to a region-specific fashion. Only a single 10-patient case series investigating ballistic fractures to the upper cervical spine (C1 and C2) exists, leaving a large gap in the understanding of this injury complex.

METHODS

A retrospective chart review was performed. Extracted data included patient demographics, neurological status on presentation, fracture morphology, assessment of stability, other associated injuries, and surgical procedures performed. Proportional analysis was performed to characterize the fractures and their associated neurological injuries.

RESULTS

Thirty-six patients were identified, with 86% being male with an average patient age of 30.0 ± 10.36 years (mean ± SD). Fracture morphology was characterized using proportional analysis. Initial neurological exams were either ASIA A or ASIA E, without any incomplete injuries noted. Patients who sustained a transcanal injury did not show any neurological improvement. The initial in-hospital mortality rate was 5.6%, with a 1-year mortality rate of 8.3%. There is a high incidence of associated vascular injury (66%) and mandible fracture (33%).

CONCLUSIONS

Ballistic penetrating trauma to the atlantoaxial spine often results in complex injury patterns necessitating multidisciplinary care with high rates of morbidity and mortality. If neurological deficits are present initially, they are often complete. Two thirds of patients sustained an associated vascular injury, which should be screened for with CT angiography.

Spine and spinal cord injuries in Syria war: treatment and outcome

STUDY DESIGN

This was a retrospective, comparative 6-year study.

OBJECTIVES

This study aimed to retrospectively analyze patients who were treated at Kilis State Hospital for spine and spinal cord injuries during the Syrian civil war and to compare the treatment results with the literature.

SETTING

Kilis State Hospital, Kilis, Turkey.

METHODS

In our study, 84 patients who were treated for spine and spinal cord injuries between December 2011 and May 2017 were examined. Patient age, sex, injury type, injury region, neurological status, time from injury to treatment, treatment methods, surgical methods applied, and complications were evaluated.

RESULTS

Of the patients, 72 were male, and 12 were female. The mean age of the patients was 23.2 ± 7.3 years. Fifty-two patients were treated surgically. Surgical treatment was applied to 44 patients with neurological deficits. At least 1-grade neurological improvement was observed in 77.3% (n = 34) of patients with neurological deficits who underwent surgical treatment. Surgical treatment was performed on 18 (34.6%) patients in the first 24 h, 27 (51.9%) patients within 24-72 h, and 7 patients (13.5%) between 72 h and 5 days. Neurological improvement was observed in all patients with neurological deficits who underwent surgical treatment in the first 24 h.

CONCLUSIONS

Early surgery (in the first 24 h) had a positive effect on the neurological recovery of the patients in our study. Thus, patients with spine and spinal cord injuries rendered a surgical-treatment decision should be operated on in a timely manner, particularly within the first 24 h.

Spinal Gunshot Wound With an Air Rifle: A Case Report

Spinal gunshot injuries are one of the most serious injuries that can cause morbidity and mortality. We report a case of a nine-year-old boy, referred to our emergency department from another hospital, with lower limb weakness after being shot by an air gun in his back. After extensive investigation, it appeared that a foreign body representing the bullet was found in his spinal canal; the patient was taken to the operating room for surgical decompression and removal of foreign bodies. After that, the patient started to show partial improvement in his neurological deficits and is to be continued on physiotherapy.

Thoracolumbar Spine Trauma

Thoracolumbar spine trauma can result in potentially life-threatening consequences and requires careful management to ensure good outcomes. The purpose of this chapter is to discuss the anatomy, diagnostic tools, non-operative, and operative treatments important when addressing thoracolumbar trauma.

Pulsed Electromagnetic Fields Ameliorate Skeletal Deterioration in Bone Mass, Microarchitecture, and Strength by Enhancing Canonical Wnt Signaling-Mediated Bone Formation in Rats with Spinal Cord Injury

Spinal cord injury (SCI) leads to extensive bone loss and high incidence of low-energy fractures. Pulsed electromagnetic fields (PEMF) treatment, as a non-invasive biophysical technique, has proven to be efficient in promoting osteogenesis. The potential osteoprotective effect and mechanism of PEMF on SCI-related bone deterioration, however, remain unknown. The spinal cord of rats was transected at vertebral level T12 to induce SCI. Thirty rats were assigned to the control, SCI, and SCI+PEMF groups (n = 10). One week after surgery, the SCI+PEMF rats were subjected to PEMF (2.0 mT, 15 Hz, 2 h/day) for eight weeks. Micro-computed tomography results showed that PEMF significantly ameliorated trabecular and cortical bone microarchitecture deterioration induced by SCI. Three-point bending and nanoindentation assays revealed that PEMF significantly improved bone mechanical properties in SCI rats. Serum biomarker and bone histomorphometric analyses demonstrated that PEMF enhanced bone formation, as evidenced by significant increase in serum osteocalcin and P1NP, mineral apposition rate, and osteoblast number on bone surface. The PEMF had no impact, however, on serum bone-resorbing cytokines (TRACP 5b and CTX-1) or osteoclast number on bone surface. The PEMF also attenuated SCI-induced negative changes in osteocyte morphology and osteocyte survival. Moreover, PEMF significantly increased skeletal expression of canonical Wnt ligands (Wnt1 and Wnt10b) and stimulated their downstream p-GSK3β and β-catenin expression in SCI rats. This study demonstrates that PEMF can mitigate the detrimental consequence of SCI on bone quantity/quality, which might be associated with canonical Wnt signaling-mediated bone formation, and reveals that PEMF may be a promising biophysical approach for resisting osteopenia/osteoporosis after SCI in clinics.

Gunshot injury to spine: An institutional experience of management and complications from a developing country

PURPOSE

Gunshot wounds are the second leading cause of spinal cord injuries. Surgical intervention for gunshot injury to the spine carries a high rate of complications. There is a scarcity of data on civilian gunshot injuries to the spine in Pakistan. Approximately 60 cases over the last 10 years have been recoded, with unusual presentation and neurological recovery. Thus it is imperative to fill this gap in data, by reviewing cases of civilian gunshot injuries to spine presenting at a tertiary care hospital (Aga Khan University Hospital, Karachi).

METHODS

This is a retrospective cohort study. Patients of all ages who presented to the emergency department of Aga Khan University Hospital, with gunshot injuries to spine between January 2005 and December 2016 were included in the study. Data were collected on neurological status (American Spinal Injury Association score was used for the initial and follow-up neurological assessment), extent of cord transection, motor and sensory deficits. The patients were further grouped into those with cord transection, and those with fractures of the bony spine but an intact spinal cord. These patients were then followed and the outcomes were recorded.

RESULTS

A total of 40 patients were identified. The mean ± SD of patients age was (30.9 ± 9.5) years. Of the 40 patients with gunshot wounds, 31 had the medical imaging performed at the facility, and hence they were included in this categorization. The remaining 9 patients were excluded from this additional grouping. Thirteen patients were managed surgically and 27 patients underwent the conservative management. The mean ± SD of follow-up was (8.7 ± 7.2) months. In our study, the thoracic spine was the most commonly injured region in gunshot injuries. Of the 31 patients with medical imaging performed at our institute, 17 (54.8%) had cord transection, of whom 8 (47%) ultimately developed paraplegia.

CONCLUSION

The prognosis of gunshot injuries to the spine can be varied depending on whether the spinal cord is intact or transected. This will help healthcare providers to plan the further management of the patient and counsel them accordingly.

Epidemiology of War-Related Spinal Cord Injury Among Combatants: A Systematic Review

STUDY DESIGN

Systematic review.

OBJECTIVES

War-related spinal cord injuries (SCIs) are commonly more severe and complex than traumatic SCIs among civilians. This systematic review, for the first time, synthesized and critically appraised the literature on the epidemiology of war-related SCIs. This review aimed to identify distinct features from the civilian SCIs that can have an impact on the management of military and civilian SCIs.

METHODS

Medline, EMBASE, and PsycINFO databases were searched for articles on epidemiology of war-related SCI among combatants, published from 1946 to December 20, 2017. This review included only original publications on epidemiological aspects of SCIs that occur during an act of war. The STROBE statement was used to examine the quality of the publications.

RESULTS

The literature search identified 1594 publications, of which 25 articles fulfilled the inclusion and exclusion criteria. The studies were classified into the following topics: 17 articles reported demographics, level and severity of SCI, mechanism of injury and/or associated bodily injuries; 5 articles reported the incidence of war-related SCI; and 6 articles reported the frequency of SCI among other war-related bodily injuries. Overall, military personnel with war-related SCI were typically young, white men, with predominantly thoracic or lumbar level, complete (American Spinal Injury Association [ASIA] Impairment Scale A) SCI due to gunshot or explosion and often associated with other bodily injuries. Marines appear to be at a greater risk of war-related SCI than the military personal in the Army, Navy, and Air Force.

CONCLUSIONS

The war-related SCIs among soldiers are distinct from the traumatic SCI in the general population. The majority of the current literature is based on the American experiences in most recent wars.

Traumatic spinal cord injury in military personnel versus civilians: a propensity score-matched cohort study

INTRODUCTION

Military personnel are exposed to mechanisms of bodily injuries that may differ from civilians. A retrospective cohort study (RCS) and a propensity score-matched cohort study (PSMCS) were undertaken to examine the potential differences in injury epidemiology, management and outcomes after spinal cord injury (SCI) between military personnel and civilians.

METHODS

Using a Canadian multicentre SCI database, data of all individuals with sufficient data from October 2013 to January 2017 were included in the RCS (n=1043). In the PSMCS, a group of 50 military personnel with SCI was compared with a group of 50 civilians with SCI who were matched regarding sex, age, and level, severity and mechanism of SCI.

RESULTS

In the RCS, military personnel with SCI (n=61) were significantly older and predominantl males when compared with civilians with SCI (n=982). However, the study groups were not statistically different with regards to their: level, severity and mechanisms of SCI; frequency of associated bodily injuries; and need for mechanical ventilation after SCI. In the PSMCS, the group of military individuals with SCI (n=50) was similar to the group of civilians with SCI (n=50) regarding pre-existing medical comorbidities, degree of motor impairment at admission, initial treatment for SCI and clinical and neurological outcomes after SCI.

CONCLUSIONS

The results of these studies suggest that military SCI group has disproportionally older men at the time of injury compared with civilians with SCI. However, the military and civilian SCI groups had similar outcomes of alike initial treatment when both groups were matched regarding their demographic profile and injury characteristics.

Comparing Blunt and Penetrating Trauma in Spinal Cord Injury: Analysis of Long-Term Functional and Neurological Outcomes

Background: Comparisons between patients with penetrating spinal cord injury (PSCI) and blunt spinal cord injury (BSCI) are scarce. Purpose: To describe baseline characteristics and neurological and functional outcomes for patients with BSCI and PSCI. Methods: Participants with BSCI (n = 5,316) and PSCI (n = 1,062) were extracted from the Spinal Cord Injury Model Systems database from January 1994 to January 2015. Participant injury and demographic characteristics were recorded. Outcomes were measured using the International Standards for Neurological Classification of Spinal Cord Injury and FIM motor scores. Outcomes for patients with American Spinal Injury Association Impairment Scale (AIS) complete injuries were analyzed separately from incomplete injuries at three time points: acute hospitalization, SCI rehabilitation, and 1-year follow-up. Results: Patients with PSCI compared to those with BSCI were more likely to present with complete injuries (56.8% vs 35.9%; p < .001) and were less likely to undergo spine surgery (19.6% vs 80.6%; p < .001). For incomplete injuries, no significant differences were observed between groups in FIM scores or AIS grade improvement at 1 year. For complete injuries, patients with BSCI showed an increased one-grade (15.7% vs 9.1%; p < .001) and three-grade (5.4% vs 1.9%; p = .014) AIS improvement at 1 year. Multivariate regression analysis demonstrated an independent effect for BSCI on AIS improvement at 1 year (odds ratio [OR], 1.74; 95% CI, 1.13-2.70; C-stat = 0.66). Conclusion: Patient with PSCI had more complete injuries and lower surgery rates. Patients with complete BSCI show greater AIS improvement at 1 year, and incomplete injuries show no difference in neurological improvement between groups. Overall, patients with PSCI demonstrated worse functional outcomes at 1 year.
