Trend differences in cervical spinal cord injuries before and after the coronavirus disease 2019 pandemic.

STUDY DESIGN: Cross-Sectional Study. OBJECTIVES: To investigate the changes in the characteristics of cervical spinal cord injuries (CSCI) before and after the coronavirus disease 2019 (COVID-19) pandemic among patients transported to our hospital in Japan. SETTING: Hospital with an emergency center in Chiba, Japan. METHODS: Patients eligible for the study were those transported within 24 h of injury and diagnosed with cervical spinal cord injury between January 2018 and December 2021 at our hospital. Medical records were retrospectively examined to investigate the number and characteristics of patients with CSCI. The clinical variables of patients with CSCI were compared according to the time of admission as related to the COVID-19 pandemic: 2018-19 (before) or 2020-21 (after). RESULTS: The total number of patients with CSCI from 2018 to 2021 was 108, with 57 before the COVID-19 pandemic and 51 after the COVID-19 pandemic. The number of severe cases with an injury severity score (ISS) of >16 decreased after COVID-19 (p < 0.05). Falls on level surfaces were the most common cause of injury both before and after COVID-19. Although the ranking of traffic accidents decreased after COVID-19, among those, the number of bicycle injuries tended to increase. CONCLUSIONS: The number of serious cases with an ISS > 16 decreased, presumably because of the decline in high-energy trauma due to the background decrease in the number of traffic accidents.

[Thyroid cartilage fracture following sneezing as a cause of spontaneous pneumomediastinum]. / Perelom shchitovidnogo khryashcha vsledstvie chikhan'ya kak prichina spontannogo pnevmomediastinuma.

OBJECTIVE: To evaluate the possible etiological factors of spontaneous pneumomediastinum and to describe a case that was unusual in its etiology: a thyroid cartilage fracture as a result of sneezing. MATERIAL AND METHODS: Six patients (four male, two female, aged 16-82 years) were hospitalized with spontaneous pneumomediastinum diagnosed with a chest X-ray in five patients and 100% with computed tomography. Treatment was symptomatic. RESULTS: The commonest symptoms (cough, shortness of breath, hoarseness) were in four patients. Spontaneous pneumomediastinum developed in three cases as a result of bronchospasm during an attack of bronchial asthma, in one patient after exercise, in one after fibrogastroscopy, in one after sneezing. We report a 30-year-old man who presenting subcutaneous emphysema on the neck, hoarseness, pain when swallowing, hemoptysis developed after sneezing. His computed tomography revealed a pneumomediastinum due to fistula of the fracture of the thyroid cartilage following sneezing while simultaneously obstructing both nostrils. At laryngoscopy, there was a linear hematoma in the resolution stage on the anterior wall of the larynx. He was treated conservatively and recovered rapidly. There are no previous published reports of spontaneous pneumomediastinum following fracture of the thyroid cartilage. CONCLUSION: Fracture of the thyroid cartilage as a result of a sharp rapid increase in airway pressure during a sneeze with blocked nasal passages can be one of the rare causes of spontaneous pneumomediastinum. Avoid closing both nostrils at the same time when sneezing.

Clinical Reasoning: A 24-Year-Old Woman With Penetrating Neck Injury From a Needlefish.

Evaluating patients with a traumatic spinal cord injury can be complicated by other injuries. In this case, a 24-year-old woman injured by a needlefish presented with combined motor and sensory defects, cranial nerve deficits, and a blunt vascular injury. This case highlights the importance of neurologic and vascular localizations and an understanding of spinal cord injuries involving various ascending and descending tracts. Appreciation of these anatomical considerations through this case illustrates the diagnostic approach to neurologic evaluation. While we present a traumatic etiology for multiple neurologic syndromes, this case gives readers an opportunity to develop a comprehensive differential diagnosis and tailor investigations for other relevant etiologies. Readers walking through this stepwise process will ultimately arrive at several distinct but related diagnoses.

Manufacture and use of transparent facial orthotic masks for treating facial burn scars: A systematic review.

BACKGROUND: Custom-made transparent facial orthoses (TFOs) (face masks) are used to improve facial burn scars. We conducted a systematic literature review on TFO manufacture and use. METHODS: Pubmed and Cochrane databases were searched without restrictions for relevant articles. TFO manufacture details and use according to international recommendations (20-32 mmHg pressure, TFO worn 20-23 h/day for ≥2 months) were extracted. RESULTS: Of 279 retrieved articles, 11 published over the last 41 years (four in the last 5 years) discussed TFO manufacture/use. There were five technical notes, five case reports, and a patient-cohort study (total patients in the studies=21). TFO-manufacture methods could be categorized as classical, digital, or mixed classical-digital. Relative clinical efficacies and cost advantages were unclear. The plastics used, harness materials, harness-point number, and silicone-interface use differed from study to study. Target pressure, actual pressure, expected daily wearing time, and treatment duration ranged widely and often did not meet current guidelines. Actual wearing time and treatment duration were never measured. CONCLUSIONS: Although TFOs play an important global role in burn care, there is a grave paucity of research. Further research is needed to promote the standardization of TFO-related practices and thereby improve the outcomes of facial-burn patients.

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.

Incomplete decapitation in suicidal vehicle-assisted ligature strangulation: A case report and a review of the literature.

Vehicle-assisted ligature strangulation is an extremely rare suicide method. We report a case of a 43-year-old man who secured one end of a nylon rope to a tree and the other end around his neck, then got inside his vehicle and stepped on the gas, leading to an incomplete decapitation. A sharply demarcated encircling ligature mark was found upon external examination, along with a deep laceration in the anterior region of the neck. The severance plane passed between the third and fourth cervical vertebrae, with diffuse haemorrhagic infiltration of the cervical muscles, in accordance with autopsy findings reported in the literature. The lung histological examination described a large amount of red blood cells and pulmonary oedema. A review of the literature concerning suicidal vehicle-assisted ligature strangulation cases allowed us to investigate some common autopsy findings, as well as the rope features relevant to the beheading.

Injury patterns and mortality associated with near-hanging in children.

BACKGROUND: The pathophysiology of near-hanging in children is different from that of adults due to anatomic, physiologic, and injury-related mechanisms, with evidence suggesting that blunt cerebrovascular injuries (BCVI) and cervical spine injuries (CSI) are uncommon. We sought to estimate the incidence of secondary injuries and their association with mortality in pediatric near-hanging victims. METHODS: We performed a retrospective observational study of children (≤17 years) with a diagnosis code for hanging between October 1, 2015 and February 28, 2023 who presented to one of 47 geographically diverse US children's hospitals. We evaluated the incidence of the following secondary injuries: cerebral edema, pneumothorax, pulmonary edema, BCVI, and CSI. We performed Fisher's exact test with Bonferroni correction to identify associations between intentionality, sex, age, and secondary injuries with mortality. RESULTS: We included 1929 children, of whom 33.8% underwent neuroimaging, 45.9% underwent neck imaging, and 38.7% underwent neck angiography. The most common injury was cerebral edema (24.0%), followed by pulmonary edema (3.2%) and pneumothorax (2.8%). CSI (2.1%) and BCVI (0.9%) occurred infrequently. Cerebral edema, pneumothorax, pulmonary edema, and younger age (≤12 years) were associated with mortality. CONCLUSIONS: In this multi-center study of pediatric near-hanging victims, BCVI and CSI occurred rarely and were not associated with mortality. While children in our study underwent neck imaging more frequently than head imaging, cerebral edema occurred more often than other injury types and imparted the highest mortality risk. Given the rarity of BCVI and CSI, a selective approach to neck imaging may be warranted in pediatric near-hanging events.

Association between swallowing disorder and prevertebral hyperintensity on magnetic resonance imaging in patients after cervical cord injury without major fracture.

This study aimed to clarify the association between swallowing disorder and prevertebral hyperintensity on magnetic resonance imaging (MRI) in patients with cervical spinal cord injury (CSCI) without a major fracture. This retrospective observational study included 30 patients who were diagnosed with acute CSCI without a major fracture (mean age: 69.3 years, 27 men). Swallowing disorder was defined as tube-dependent nutrition because of obvious aspiration 28 days after injury. The high-intensity area (HIA) and anteroposterior width (HIW) of the prevertebral space at C1-7 levels were measured using MRI short-TI inversion recovery midsagittal images. Receiver operating characteristic curve analysis was used to determine the optimal cutoff values of the HIA for predicting swallowing disorder. The incidence of swallowing disorder after CSCI was 16.7%. The HIA was significantly higher in the swallowing disorder group (median, 409.0 mm2) than in the non- swallowing disorder group (median, 159.1 mm2) (P = .04). There was no significant difference in HIW between the two groups. The optimal cutoff point of the HIA was measured at 203.2 mm2 with 80.0% and 20.0% sensitivity and specificity, respectively, with an area under the curve of 0.848 (95% confidence interval, 0.657-1.000, P = .01). The prevertebral hyperintensity area on MRI for swallowing disorder in patients after cervical cord injury without skeletal injury is associated with swallowing disorder. The optimal cutoff point of the area was determined to be 203.2 mm2.

Displaced transverse laryngeal fracture from attempted hanging.

Laryngeal fractures are life-threatening injuries, frequently associated with long-term morbidity. We present a case of a man sustaining a displaced laryngeal fracture and rupture of supraglottic structures following attempted suicide by hanging from a bridge. His injuries included a tear of the thyrohyoid membrane, avulsed epiglottis and complete autopharyngotomy. All laryngeal functions were significantly impaired. Early tracheostomy, careful surgical repair, extensive multidisciplinary team (MDT) input and intensive rehabilitation all contributed towards a successful recovery. By 7 months following the initial injury, the patient had achieved excellent breathing and voicing, and a safe and competent swallow despite the extent of his initial injuries. This case demonstrates the importance of early airway management in laryngeal trauma and the role of surgical management in conjunction with swallow rehabilitation. Fundamentally, an MDT approach is essential for the holistic management of patients with laryngeal trauma.

Rib Plating Outcomes in Elderly Trauma Patients With Multiple Rib Fractures: A Community Hospital Experience.

Rib fractures in the elderly are one of the most common injuries in trauma patients admitted to the hospital, accounting for over 350,000 patients annually in the United States. Rib plating has been shown to be most beneficial among certain populations. Early surgical intervention is important to utilize approaches that limit the use of pain medications. This is a retrospective data analysis to determine the efficacy of rib plating in elderly trauma patients with rib fractures. A total of 253 patients were seen with rib fractures, 63% were male and 37% were female. The mean age is 64 ± 18.5 years. Of these patients analyzed, 76% had an associated comorbid condition. A majority of patients (95%) presented to the emergency department (ED) with mild GCS range (13-15). Moderate GCS range (9-12) was 4%, and 3% of patients were with severe GCS (3-8.) The mean ISS was 10. The overall mortality rate was 4.5%. Patients were divided into 2 groups: group I consisted of patients who received open reduction and fixation of the fractured ribs, and group II was patients managed conservatively without surgery. Statistical analyses using Student's t-test and Chi-square test were performed. Institutional Review Board approval was obtained for this study. Rib plating in elderly trauma patients with multiple rib fractures has shown to be beneficial in terms of mortality. Furthermore, geriatric patients with comorbidities will benefit from early open reduction and fixation of rib fractures, though a larger study is needed to establish clearer criteria for rib plating.

Thyroid gland injury after blunt neck trauma: a case report.

Soft-tissue injuries are relatively common after blunt neck trauma. Due to neck content, several vital structures can be compromised. Isolated trauma to the thyroid is highly uncommon, and few cases are reported in the literature. A 61-year-old otherwise healthy woman sustained blunt trauma to the left frontal half of the neck caused by seatbelt injury in a motor vehicle accident. She presented with a painful anterior neck swelling associated with dyspnea. Computed tomography showed the left thyroid lobe lacerations with features suggestive of thyroid gland active bleeding. She underwent surgical exploration with left thyroidectomy and recovered un-eventfully. Isolated thyroid gland injury is infrequent and is present in about 1-2% of the cases, and in most reported cases, there is an underlining pathology within the gland. Patients can be present with neck swelling, pain, respiratory distress, and dysphagia. Patients who sustained blunt neck trauma should be assessed and stabilized according to the ATLS® principles. Injury to vital structures should be ruled out first. Although these cases are rare, physicians should consider the possibility of thyroid injury after blunt neck trauma or neck swelling is noted.

Prognostic impact of respiratory dysfunction in elderly patients with cervical spinal cord injury and/or fractures: a multicenter survey.

PURPOSE: To investigate the impact of early post-injury respiratory dysfunction for neurological and ambulatory ability recovery in patients with cervical spinal cord injury (SCI) and/or fractures. METHODS: We included 1,353 elderly patients with SCI and/or fractures from 78 institutions in Japan. Patients who required early tracheostomy and ventilator management and those who developed respiratory complications were included in the respiratory dysfunction group, which was further classified into mild and severe respiratory groups based on respiratory weaning management. Patient characteristics, laboratory data, neurological impairment scale scores, complications at injury, and surgical treatment were evaluated. We performed a propensity score-matched analysis to compare neurological outcomes and mobility between groups. RESULTS: Overall, 104 patients (7.8%) had impaired respiratory function. In propensity score-matched analysis, the respiratory dysfunction group had a lower home discharge and ambulation rates (p = 0.018, p = 0.001, respectively), and higher rate of severe paralysis (p < 0.001) at discharge. At the final follow-up, the respiratory dysfunction group had a lower ambulation rate (p = 0.004) and higher rate of severe paralysis (p < 0.001). Twenty-six patients with severe disability required respiratory management for up to 6 months post-injury and died of respiratory complications. The mild and severe respiratory dysfunction groups had a high percentage of severe paraplegic cases with low ambulatory ability; there was no significant difference between them. The severe respiratory dysfunction group tended to have a poorer prognosis. CONCLUSION: Respiratory dysfunction in elderly patients with SCI and/or cervical fracture in the early post-injury period reflects the severity of the condition and may be a useful prognostic predictor.

Blunt traumatic female urethral and bladder neck injuries: a 15-year single-institution experience.

PURPOSE: To describe our experience in the management and outcomes of female patients with urethral or bladder neck (BN) injury at a high-volume Level 1 trauma center. METHODS: A retrospective chart review of all female patients with urethral or BN injury by blunt trauma mechanism admitted to a Level 1 trauma center between 2005 and 2019 was performed. RESULTS: Ten patients met study criteria with median age 36.5 years. All had concomitant pelvic fractures. All injuries were confirmed operatively, with no delayed diagnoses. Two patients were lost to follow up. One patient was not eligible for early repair of urethral injury and had two repairs of a urethrovaginal fistula. Two of seven (29%) patients who underwent early repair of their injury had an early Clavien grade > 2 complication, with none reporting long-term complications at median follow-up of 15.2 months. CONCLUSIONS: Intraoperative evaluation is critical in the diagnosis of female urethral and BN injury. In our experience, acute surgical complications are not uncommon after the management of such injuries. However, there were no reported long-term complications in those patients who had prompt management of their injury. This aggressive diagnostic and surgical strategy is instrumental in attaining excellent surgical outcomes.

Is severe traumatic brain injury no longer a contraindication for surgical stabilization of rib fractures in patients with multiple rib fractures? A propensity-matched analysis.

BACKGROUND: Traumatic brain injury (TBI) is often considered a contraindication to surgical stabilization of rib fractures (SSRF). In this study, we hypothesized that, compared with nonoperative management, SSRF is associated with improved outcomes in TBI patients. METHODS: Using the American College of Surgeons Trauma Quality Improvement Program 2016-2019, we performed a retrospective analysis of patients with concurrent TBI and multiple rib fractures. Following propensity score matching, we compared patients who underwent SSRF with those who were managed nonoperatively. Our primary outcome was mortality. Secondary outcomes included ventilator-associated pneumonia, hospital and intensive care unit (ICU) length of stay (LOS), ventilator days, tracheostomy rate, and hospital discharge disposition. In a subgroup analysis, we stratified patients into mild and moderate TBI (GCS score >8) and severe TBI (GCS score ≤8). RESULTS: Of 36,088 patients included in this study, 879 (2.4%) underwent SSRF. After propensity-score matching, compared with nonoperative management, SSRF was associated with decreased mortality (5.4% vs. 14.5%, p < 0.001), increased hospital LOS (15 days vs. 9 days, p < 0.001), increased ICU LOS (12 days vs. 8 days, p < 0.001), and increased ventilator days (7 days vs. 4 days, p < 0.001). In the subgroup analyses, in mild and moderate TBI, SSRF was associated with decreased in-hospital mortality (5.0% vs. 9.9%, p = 0.006), increased hospital LOS (13 days vs. 9 days, p < 0.001), ICU LOS (10 days vs. 7 days, p < 0.001), and ventilator days (5 days vs. 2 days, p < 0.001). In patients with severe TBI, SSRF was associated with decreased mortality (6.2% vs. 18%, p < 0.001), increased hospital LOS (20 days vs. 14 days, p = 0.001), and increased ICU LOS (16 days vs. 13 days, p = 0.004). CONCLUSION: In patients with TBI and multiple rib fractures, SSRF is associated with a significant decrease in in-hospital mortality and with longer hospital and ICU LOSs. These findings suggest that SSRF should be considered in patients with TBI and multiple rib fractures. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level III.

Review article: Non-penetrating neck artery dissection in young adults: Not to be missed!

Young adults who present to the ED with neck pain following non-penetrating, seemingly trivial trauma to the neck, are at risk of neck artery dissection and subsequent stroke. Sport-related neck injury is the chief cause. Physical examination may often be unremarkable, and although there may be reluctance to expose young patients to radiation, radiological imaging is central to making a diagnosis of arterial wall disruption. A comprehensive literature search was performed in relation to neck artery dissection, and the evidence was scrutinised. We discuss the typical mechanism of injury, symptoms, anatomical considerations and clinical aids in diagnosis of neck artery dissection. Although the incidence is low, neck artery dissection has a mortality of 7%. As such, it is important for front-line physicians to have a high suspicion of the diagnosis and a low threshold to organise radiological examinations, specifically computerised tomography. Early detection of neck artery dissection will trigger clinical protocols that call for multi-disciplinary team management of this condition. In general, guideline-based recommendation for the management of neck artery dissection involving an intimal flap is by anti-platelet therapy while treatment of neck artery dissection that results in a pseudo-aneurysm or thrombosis is managed by surgical intervention or endovascular techniques. Close follow up combined with antithrombotic treatment is recommended in these individuals, the goal being prevention of stroke.

Airway Obstruction with Blunt Neck Trauma from an Accidental High Tackle in Rugby.

ABSTRACT: Blunt neck trauma is an uncommon condition in sports yet life-threatening if left untreated; hence, early diagnosis and management is necessary once suspected. We report a collegiate rugby player tackled around the neck during intersquad scrimmage. He broke his cricoid and thyroid cartilage, resulting in cervical subcutaneous emphysema and pneumomediastinum and eventually, airway obstruction. Thus, he underwent cricothyroidotomy and emergency tracheotomy. After 20 d, the emphysema disappeared. However, dilation failure of the vocal cord remained, thereby requiring laryngeal reconstruction. In conclusion, blunt neck trauma can cause airway obstruction in various sports.

Prognostic MRI parameters in acute traumatic cervical spinal cord injury.

PURPOSE: The aim of this study is to estimate the prognostic value of some features documented on preoperative MRI study in patients with acute cervical spinal cord injury. METHODS: The study was conducted in patients operated for cervical spinal cord injury (cSCI) from April 2014 to October 2020. The quantitative analysis on preoperative MRI scans included: length of the spinal cord intramedullary lesion (IMLL the canal diameter at the level of maximal spinal cord compression (MSCC) and the presence of intramedullary hemorrhage. The canal diameter at the MSCC was measured on the middle sagittal FSE-T2W images at the maximum level of injury. The America Spinal Injury Association (ASIA) motor score was used for neurological assessment at hospital admission. At 12-month follow-up all patients were examined with the SCIM questionnaire. RESULTS: At linear regression analysis, the length of the spinal cord lesion [ß coefficient -10.35, 95% confidence interval (CI)-13.71 to-6.99; p < 0.001], the diameter of the canal at the level of the MSCC (ß coefficient 6.99, 95% CI 0.65 to 13.33; p = 0.032), and the intramedullary hemorrhage (ß coefficient - 20.76, 95% CI - 38.70 to - 2.82; p = 0.025), were significantly associated with the score at the SCIM questionnaire at one year follow-up: shorter spinal cord lesion, greater diameter of the canal at the level of the MSCC, and absence of intramedullary hemorrhage were predictors of better outcome. CONCLUSION: According to the findings of our study, the spinal length lesion, canal diameter at the level of spinal cord compression and intramedullary hematoma documented by the preoperative MRI study were associated with the prognosis of patients with cSCI.
