Right side traumatic diaphragmatic hernia presented after 20 years with shortness of breath; a rare case presentation, and literature review.

INTRODUCTION: A right side diaphragmatic injury was linked to serious trauma to the abdomen, pelvis, and chest. The most significant type of injury was blunt abdominal trauma sustained in a car collision. The left side was more likely than the right to experience herniation. The stomach and colon were the most often herniated abdominal viscera. In the same location as the diaphragm rupture, there were rib fractures, hemothorax, and liver damage. Delayed diaphragmatic rupture with diaphragmatic hernia is rare and has a mysterious nature. CASE PRESENTATION: A 68 years old female patient who has repeated history of shortness of breath, for which she treated as lung infection presented with sudden exacerbation of shortness of breath, she witnessed history of blunt trauma 20 years back and up on investigation bowel herniation to the chest cavity diagnosed. Posteriolateral thoracotomy done, the herniated bowel reduced and the diaphragmatic defect repaired. The patient significantly improved and discharged from the hospital smoothly on 4th postoperative day. DISCUSSION: Careful recording of past history and physical examination are the best approaches in diagnosing delayed presentation of traumatic diaphragmatic rupture. CT scan with reconstruction of the diaphragm is helpful in both diagnosis and differential diagnosis. Surgical therapy after diagnosis is the best treatment. CONCLUSION: Delayed right side diaphragmatic hernia is a rare entity resulting in grave consequences, In a patient with history of trauma there should be a high index of suspension and patients should undergo imaging and surgical management is the best treatment.

Earthquake-related isolated blunt thoracic trauma patients: A special population study in the emergency department.

OBJECTIVE: The objective of this study is to compare patients with severe and mild blunt thoracic trauma, who survived an earthquake and presented to the emergency department (ED), in order to identify factors influencing the severity of trauma in earthquake-related thoracic injuries. METHODS: This retrospective, cross-sectional, observational comparative study included patients with isolated thoracic injuries due to the February 6th Kahramanmaras earthquake. The patients were categorized into severe and mild groups based on chest trauma scoring (CTS), and their characteristics were compared. RESULTS: The study included 53 patients, with 43 (88.1%) classified as having mild thoracic trauma and 10 (18.9%) classified as having severe thoracic trauma. There was no significant difference in the duration of entrapment between the groups (p = 0.824). The incidence of hemothorax, pneumothorax, rib fractures, and pneumomediastinum did not differ significantly between the two groups (p > 0.05). However, severe thoracic trauma was associated with a higher rate of lung contusion compared to the mild group (p = 0.045). The severe group exhibited significantly higher median scores for lung contusion, rib fractures, and total CTS compared to the mild group (p < 0.001). The mortality rate was significantly higher in the severe group (40%, n = 4) compared to the mild group (2.3%, n = 1) (p = 0.003). CONCLUSION: The duration of entrapment did not significantly affect the severity of thoracic injuries in earthquake-related blunt thoracic trauma. However, lung contusion was found to be a more prominent feature in these injuries compared to other clinical conditions such as hemothorax and pneumothorax. These findings highlight the distinct clinical implications of earthquake-related thoracic trauma and may have implications for management strategies in these cases.

Traumatic injuries by conducted electrical weapons: Case report of self-injury to the hand during stun gun training.

The use of non-lethal weapons has spread worldwide, being introduced as an alternative to firearms in many countries such as the United States or the United Kingdom. Among non-lethal weapons, conducted electrical weapons have been adopted worldwide, to control unruly suspected criminals or to neutralise violent situations. The stun gun belongs to this category and is the most widely available, with more than 140,000 units in use by police officers in the field in the US, and an additional 100,000 electrical stun guns owned by civilians worldwide. In Italy, the use of conducted electrical weapons by law enforcement has only recently been introduced, with private use and commercialisation still prohibited, mainly due to controversies related to the potential dangers of such devices.Before the official adoption, several experiments had to be carried out, with mechanisms that reproduced the ballistics of the stun gun. Here we present the case of a man who suffered a self-injury trauma to his hand during a ballistics exercise with a crossbow loaded with stun gun probes.

Breast Reconstruction after Blunt Breast Trauma: Systematic Review and Case Report Using the Ribeiro Technique.

Blunt breast trauma occurs in 2% of blunt chest injuries. This study aimed to evaluate the evidence on breast reconstruction after blunt trauma associated with the use of a seat belt. Also, we describe the first case of breast reconstruction using the Ribeiro technique. In November 2022, a systematic search of MEDLINE, EMBASE, and Google Scholar databases was conducted. The literature was screened independently by two reviewers, and the data was extracted. Our search terms included breast, mammoplasty, blunt injury, and seat belts. In addition, we present the case of a woman with a left breast deformity and her reconstruction using the inferior Ribeiro flap technique. Six articles were included. All included studies were published between 2010 and 2021. The studies recruited seven patients. According to the Teo and Song classification, seven class 2b cases were reported. In five cases a breast reduction was performed in the deformed breast with different types of pedicles (three superomedial flaps, one lower flap, one superior flap). Only one case presented complications. The case here presented was a type 2b breast deformity in which the lower Ribeiro pedicle was used successfully without complications during follow-up. Until now there has been no consensus on reconstructive treatment due to the rarity of this entity. However, we must consider surgical treatment individually for each patient. We believe that the Ribeiro technique is a feasible and safe alternative in the treatment of posttraumatic breast deformities, offering very good long-term results.

Hypothenar Hammer Syndrome Presenting as Critical Limb Ischemia in a 41-year-Old Caucasian Female; A Case Report.

Traumatic injuries to the hand are commonly encountered in the adult population. Arterial occlusion from digital emboli due to thrombosis is a less frequently observed etiology. An example is hypothenar hammer syndrome, which usually arises following a mechanical injury. We report a case of hypothenar hammer syndrome in a 41-year-old Caucasian female following a blunt injury from exercise. She presented to our facility with complaints of intermittent severe pain in her left hand with discoloration of her fourth and fifth digits. Her symptoms began following an intense upper body strength exercise session and recurred intermittently over the following four to six weeks. MRI of the left hand showed no bony fractures or soft tissue injury. She was commenced on aspirin and Xarelto and subsequently had an arteriogram revealing thrombosis in the distal left ulnar artery. She ultimately had surgical resection of the thrombosed artery with repair using a venous graft which led to the resolution of her symptoms. Xarelto was discontinued after surgery, but she remains on Aspirin.

Traumatic hemorrhage of the thyroid as a work-related injury: a case report and review of the literature.

Traumatic hemorrhage of the thyroid gland resulting from blunt injury to the neck is a very rare event. Particular neck positions can expose the thyroid to trauma, especially in motor vehicle collisions, falls, direct blows, or sport activities. Preexisting conditions such as goiters, adenomas, and cysts can increase the risk of bleeding, reducing the force required to rupture the gland and make the thyroid more prone to injury. The authors report the case of a 53-year-old man who was involved in a fire while working on maintenance of a liquid petroleum gas (LPG)-powered car. He subsequently presented to the emergency department with painful swelling of his right anterior neck with a palpable mass. CT scan showed a right thyroid hemorrhagic cyst. The worker reported that he had jumped into the car trunk to extinguish the fire and covered the gas tank nozzle with his own body to prevent dispersal of the accelerant. In this case, the medico-legal evaluation was useful to delineate between natural and traumatic causes of the injury. Medico-legal assessment is key in understanding the dynamics involved in work-related events to identify any legal responsibilities of the worker or the employer.

Hepatic subcapsular hematoma without elevated hepatic enzyme levels: A case report.

In cases of abdominal trauma, elevated liver enzyme levels can indicate hepatic injury. To date, there are no documented reports of hepatic trauma without liver enzyme abnormalities. Herein, we present a case of hepatic subcapsular hematoma following a motor vehicle accident without abnormal findings in blood and biochemical tests over the course of time. The patient was a woman in her 20s who had collided with a passenger car while driving a light motor vehicle. She walked by herself to see a nearby after-hour doctor as an outpatient. Radiography was performed, and the patient was discharged on the same day. She was reexamined the next day and referred to our medical center due to possible hepatic injury. Her respiratory and circulatory dynamics were stable; however, she experienced mild tenderness in her right upper abdomen upon arrival. Echo-free space was observed in Morrison's and Douglas' pouches on abdominal ultrasound, and abdominal computed tomography showed a hepatic subcapsular hematoma (grade II according to the American Association for the Surgery of Trauma liver injury scale). However, blood and biochemical tests did not reveal any abnormalities. The hematoma reduced with conservative treatment after admission, and the patient was discharged on the 18th hospital day. This case indicates that hepatic injury cannot be ruled out based on serodiagnosis alone; thus, diagnostic imaging is required in cases of blunt abdominal trauma.

The progression of traumatic Stanford type A acute aortic dissection.

Key Clinical Message: Cardiopulmonary bypass for trauma patients carries the risk of bleeding from injured organs, while traumatic aortic dissection can progress rapidly. It is sometimes difficult to determine the optimal time for aortic repair in trauma patients. Abstract: An 85-year-old woman was diagnosed with traumatic ascending aortic dissection, right clavicle and left first rib fracture, and abdominal contusions after a vehicle accident. After admission, the aortic dissection progressed, and emergent surgery was performed. Although the risk of hemorrhagic complications needs to be evaluated, prompt aortic repair is required.

The edemiological state of blunt diaphragmatic injury: An analysis of a nationwide trauma registry in Japan.

BACKGROUND: Little is known about blunt traumatic diaphragmatic injury (BTDI). This study aimed to investigate the epidemiological state of BTDI, using a nationwide trauma registry in Japan. METHODS: Data of patients aged ≥18 years who experienced blunt injury between January 2004 and May 2019 were extracted from the Japan Trauma Data Bank. Demographics, cause of trauma, mechanism of injury, physiological parameters, organ injuries, and bone fractures were compared between patients with and those without BTDI. Multivariable logistic regression analysis was performed to identify factors associated with BTDI. RESULTS: A total of 305,141 patients from 244 hospitals were analyzed. The median patient age (interquartile range) was 65 (44-79) years, and 185,750 (60.9%) were men. BTDI was diagnosed in 868 patients (0.3%). The prevalence of BTDI was stable, between 0.2 and 0.6%, over the study period. Among the 868 patients with BTDI, 408 (47.0%) fatalities were recorded. Mortality rates in each year were 42.5-68.2%, with no significant trend toward an improved outcome (P = 0.925). Our multivariable logistic regression analysis found that mechanism of injury, Glasgow Coma Scale score (9-12 or 3-8) on hospital arrival, hypotension (systolic blood pressure <90 mmHg) on hospital arrival, organ injuries (lung, heart, spleen, bladder, kidney, pancreas, stomach, and liver), and bone fractures (rib, pelvis, lumbar spine, and upper extremities) were independently associated with BTDI. CONCLUSION: Using a nationwide trauma registry, this study revealed the epidemiological state of BTDI in Japan. BTDI was found to be a very rare but devastating injury, with high in-hospital mortality. Some clinical factors, such as mechanism of injury, Glasgow Coma Scale score, organ injuries, and bone fractures, were independently associated with BTDI.

Blunt Thoracic Aortic Injury.

Blunt thoracic aortic injury (BTAI) is a potentially fatal condition that needs prompt recognition and expedited management. Clinical manifestations of BTAI are not straight forwarding and may be misdiagnosed. The grade of aortic injury is an important determinant of perioperative mortality and morbidity, as well as the indication of treatment, along with the presence of concomitant lesions of other involved organs. The mainstay of treatment nowadays for hemodynamically stable patients who survive the trauma scene is represented by delayed endovascular repair whenever anatomically and clinically feasible. Endovascular repair, in fact, is burdened by lower perioperative mortality and morbidity rates if compared to open surgical repair, but concerns remain about the need for long-term surveillance and radiation exposure in patients who are at a younger age than patients treated for the aneurysmal disease. The aim of the paper is to provide an update on the diagnostic modalities and strategies of treatment for patients affected by BTAI.

Surgical interventions and outcome in a population of feline trauma patients.

OBJECTIVE: To determine signalment, injury type, trauma severity score, and outcome of feline trauma patients undergoing surgical (emergency room [ER] and operating room [OR]) and nonsurgical treatments in addition to time to surgery, specialty services involved, and cost in the OR surgery population. DESIGN: Retrospective evaluation of medical record and hospital trauma registry data on feline trauma cases. SETTING: University teaching hospital. ANIMALS: Two hundred and fifty-one cats presenting for traumatic injury between May 2017 and July 2020. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Demographics and outcomes were compared for cats undergoing surgical intervention in an OR (12%, 31/251) or an ER (23%, 58/251) setting and feline trauma patients without surgical intervention (65%, 162/251). Between the 2 surgical groups, 99% survived to discharge compared to 73.5% of the nonsurgical group (P < 0.0001). For the OR surgical cohort, electronic medical records were reviewed to determine the specialty surgery service involved, time to and duration of anesthesia and surgery, and visit cost. The most common surgery services involved were orthopedics (41%, 12/29) and dentistry (38%, 11/29), and the most common surgeries performed were mandibular fracture stabilization (8/29) and internal fixation for long bone fractures (8/29). The ER surgical group had a significantly lower Animal Trauma Triage score than the OR group (P < 0.0001), but a significant difference was not found between OR surgical and nonsurgical groups (P = 0.0553). No difference in modified Glasgow Coma Scale score was found between any groups. CONCLUSIONS: Surgical intervention in feline trauma patients appears to be associated with higher survival rates, but no difference in mortality was found across surgery services. OR surgical intervention, in particular, orthopedic surgery, was associated with increased length of hospitalization, increased cost, and increased use of blood products.

Endovascular Aortic Repair for Thoracic Aortic Compression Resulting From Chance Fracture of the Thoracic Spine.

Blunt aortic injury is a serious condition with a high mortality rate. Although rare, blunt aortic injury associated with spinal fracture has also been reported, and appropriate management of aortic disease is key to a good outcome. This report is a case of a 78-year-old man who was found to have a transverse fracture (Chance fracture) in the ninth thoracic vertebra, with a sharp bone fragment compressing the thoracic aorta. Early spinal surgery was needed; however, there was concern about the possibility of bleeding from the aorta and surrounding small arteries associated with the bone fragment during spinal surgery. Therefore, thoracic endovascular aortic repair was performed before spinal surgery. The next day after thoracic endovascular aortic repair, posterior spinal instrumentation was performed, and the postoperative course was uneventful. Because aortic injury associated with vertebral fracture can lead to massive bleeding and spinal cord injury, endovascular repair before spinal surgery is reasonable.

Social Determinants of Health Impact Physical Recovery After Blunt Injury.

As defined by the United States Department of Health and Human Services, the Social Determinants of Health (SDOH) are conditions in the environment that affect health function and outcomes. The SDOH are divided into the following categories: economic stability, education access and quality, health care access and quality, neighborhood and built environment, and social and community content. It is known that SDOH impact long-term health outcomes. The influence that SDOH have on physical recovery after acute injury is less understood, however. In this study, patients who suffered a traumatic blunt injury completed a survey 12-14 months post-injury to assess their SDOH and physical health before and after their injury. The results showed that for the cohort of patients studied SDOH was the greatest predictor of long-term recovery, having a stronger correlation with recovery than injury severity score (ISS) or hospital length of stay (HLOS).

Therapeutic management and amputation options in a long time delayed blunt popliteal artery injury.

PURPOSE: To report the experience of treatment on blunt traumatic popliteal artery injury (PAI) combined orthopedic injuries and determine the amputation-associated factors. METHODS: From January 2008 to December 2019, 55 patients in level I trauma center with traumatic blunt PAI were retrospectively reviewed. Variables were retrospectively collected and statistically analyzed. Patients with PAI with limb selvage, primary amputation, and secondary amputation were retrospectively grouped and compared. RESULTS: A total of 55 patients with a median age of 41.4 years (range 18-70), of which 45 were males (81.8%) and 10 were females (18.2%), were enrolled. The overall amputation rate was 36.4% because 88.6% of patients faced more than 6 h of delay before treatment. The average injury severe score (ISS) and abbreviated injury score (AIS) were 10.4 (range 9-34) and 8.2 (range 5-16), respectively. Multivariate regression analysis showed that the number of hospitalization days was a significantly related factor to amputation. After a median follow-up of 56 months (range 12-132), no death, another limb loss, or claudication was found in all patients. CONCLUSIONS: Patients with PAI are commonly accompanied by multiple injuries that increase the risk of amputation; therefore, timely treatments are urgently required. Reducing the severity of ischemia by fasciotomy, not losing time by performing preoperative imaging or diagnostic tests, and repairing the associated venous injury can help to optimize the rates of limb salvage. However, impact factors, such as the gender and age of the patient, injured mechanisms, concomitant injuries, AIS, ISS, and surgical times, are not associated with the outcomes of amputation. Nonetheless, endeavors to salvage the limbs as far as possible should be made.

Systematic review and meta-analysis of long-term reintervention following thoracic endovascular repair for blunt traumatic aortic injury.

OBJECTIVE: To investigate the long-term reinterventions of thoracic endovascular repair (TEVAR) after blunt traumatic aortic injury. METHODS: MEDLINE, EMBASE, and Cochrane databases were interrogated until June 2021. Inclusion criteria were blunt traumatic aortic injury treated with TEVAR and mean follow-up of more than 60 months. A systematic review was conducted and data were pooled using a random effects model of proportions applying the Freeman-Tukey transformation. Late reintervention was the primary outcome. Secondary outcomes were procedure-related complications (endoleak, in-stent thrombosis, occlusion, infolding/collapse, bird-beak, migration, and left arm claudication), overall and aortic-related mortality, and aortic diameter changes. RESULTS: Eleven studies with a low quality assessment were included. Four hundred eight patients were collected and the 389 surviving more than 30 days were included. The mean follow-up was 8.2 years (95% confidence interval [CI], 5.7-10.8; I2 = 40.2%). Late reintervention was 2.1% (95% CI, 0.6-3.9; I2 = 0.0%; 11/389 cases) with 0.1% (95% CI, 0.0-1.2; I2 = 0.0%; 3/389) occurring after 5 years. Bird-beak was identified in 38.7% (95% CI, 16.4-63.6; I2 = 86.6%). Left arm claudication occurring after 30 days was 3.1% (95% CI, 0.1-8.6; I2 = 26.9%; 11/140 cases). In-stent thrombosis was 1.9% (95% CI, 0.1-5.2; I2 = 51.8%; 11/389 cases). Endoleak was 0.5% (95% CI, 0.0-1.9; I2 = 0.0%; 5/389 cases). Infolding, occlusion, and migration were reported in 2 of 389, 1 of 389, and 0 of 389 patients, respectively. Overall late survival was 95.6% (95% CI, 88.1-99.8; I2 = 84.7%; 358/389 patients) and only one patient accounted for aortic related mortality. The increase in proximal and distal aortic diameters was estimated at 2.7 mm (95% CI, 1.2-4.3; I2 = 0.0%) and 2.5 mm (95% CI, 1.1-3.9; I2 = 0.0%), respectively. CONCLUSIONS: TEVAR demonstrates remarkably good long-term results and reinterventions are rarely required. Aortic reinterventions tend to occur within the first and after the fifth year.

The Blunt Liver and Spleen Trauma (BLAST) audit: national survey and prospective audit of children with blunt liver and spleen trauma in major trauma centres.

PURPOSE: To compare the reported and observed management of UK children with blunt liver or spleen injury (BLSI) to the American Pediatric Surgical Association (APSA) 2019 BLSI guidance. METHODS: UK Paediatric Major Trauma Centres (pMTCs) undertook 1 year of prospective data collection on children admitted to or discussed with those centres with BLSI and an online questionnaire was distributed to all consultants who care for children with BLSI in those centres. RESULTS: All 21/21 (100%) pMTCs participated; 131 patients were included and 100/152 (65%) consultants responded to the survey. ICU care was reported and observed to be primarily determined using haemodynamic status or concomitant injuries rather than injury grade, in accordance with APSA guidance. Bed rest was reported to be determined by grade of injury by 63% of survey respondents and observed in a similar proportion of patients. Contrary to APSA guidance, follow-up radiological assessment of the injured spleen or liver was undertaken in 44% of patients before discharge and 32% after discharge, the majority of whom were asymptomatic. CONCLUSIONS: UK management of BLSI differs from many aspects of APSA guidance. A shift towards using clinical features to determine ICU admission and readiness for discharge is demonstrated, in line with a strong evidence base. However, routine bed rest and re-imaging after BLSI is common, contrary to APSA guidance. This disparity may exist due to concern that evidence around the incidence, presentation and natural history of complications after conservatively managed BLSI, particularly bleeding from pseudoaneurysms, is weak.

Association of antiplatelet or anticoagulant agents with in-hospital mortality among blunt torso trauma patients without severe traumatic brain injury: A retrospective analysis of the Japanese nationwide trauma registry.

AIM: Patients with head trauma who take antiplatelet or anticoagulant (APAC) agents have a higher rate of mortality. However, the association between these agents and mortality among blunt torso trauma patients without severe traumatic brain injury remains unclear. METHODS: Using the Japanese nationwide trauma registry, we conducted a retrospective cohort study including adult patients with blunt torso trauma without severe head trauma between January 2019 and December 2020. Eligible patients were divided into two groups based on whether or not they took any APAC agents. The primary outcome was in-hospital mortality. To adjust for potential confounding factors, we conducted random effects logistic regression to account for patients clustering within the hospitals. The model was adjusted for potential confounders, including age, mechanism of injury, Charlson comorbidity index, systolic blood pressure, and injury severity scale on arrival as potentially confounding factors. RESULTS: During the study period, 16,201 patients were eligible for the analysis. A total of 832 patients (5.1%) were taking antiplatelet or anticoagulant agents. Overall in-hospital mortality was 774 patients (4.8%). APAC group had a higher risk of in-hospital mortality compared with the non-APAC group (6.9% vs. 4.7%; unadjusted OR, 1.51; 95% CI, 1.12-2.00; P < 0.01). After adjusting for potential confounder, there were no significant intergroup difference in a higher in-hospital mortality compared to with the non-APAC group (OR, 1.07; 95%CI, 0.65-1.77; P = 0.79). CONCLUSION: The use of APAC agents before the injury was not associated with higher in-hospital mortality among blunt torso trauma patients without severe traumatic brain injury.

High-energy blunt pelvic ring injury: dataset of patients and injury characteristics from a severely injured patients' registry.

Since mid-2013, data on high-energy trauma patients admitted to the Emergency Department of the University Hospitals of Geneva, Switzerland, are prospectively recorded in a dedicated registry. This includes data on patients with high-energy blunt pelvic ring injuries (PRI), defined as closed fracture of the pelvic ring following falls from a height >1 m, road traffic accidents, sport, crush, farm and industrial injuries. The registry was screened for patients aged ≥16 years with high-energy blunt PRI admitted to the aforementioned academic level I trauma center between 2014.01.01 et 2019.12.31, to assess the outcome of the institutional PRI management protocol. Data on 195 patients were collected and analyzed for this purpose [1]. The dataset "patients' demographic and injury characteristics" provides the raw demographics and Abbreviated Injury Scale (AIS) of these 195 patients. These data can contribute to the knowledge of patients' demographics and injury characteristics of high-energy blunt PRI patients.

Reconstruction and Quantitative Evaluation of Blunt Injury Cases by Finite Element Method.

OBJECTIVES: To reconstruct the cases of acceleration craniocerebral injury caused by blunt in forensic cases by finite element method (FEM), and to study the biomechanical mechanism and quantitative evaluation method of blunt craniocerebral injury. METHODS: Based on the established and validated finite element head model of Chinese people, the finite element model of common injury tool was established with reference to practical cases in the forensic identification, and the blunt craniocerebral injury cases were reconstructed by simulation software. The cases were evaluated quantitatively by analyzing the biomechanical parameters such as intracranial pressure, von Mises stress and the maximum principal strain of brain tissue. RESULTS: In case 1, when the left temporal parietal was hit with a round wooden stick for the first time, the maximum intracranial pressure was 359 kPa; the maximum von Mises stress of brain tissue was 3.03 kPa at the left temporal parietal; the maximum principal strain of brain tissue was 0.016 at the left temporal parietal. When the right temporal was hit with a square wooden stick for the second time, the maximum intracranial pressure was 890 kPa; the maximum von Mises stress of brain tissue was 14.79 kPa at the bottom of right temporal lobe; the maximum principal strain of brain tissue was 0.103 at the bottom of the right temporal lobe. The linear fractures occurred at the right temporal parietal skull and the right middle cranial fossa. In case 2, when the forehead and left temporal parietal were hit with a round wooden stick, the maximum intracranial pressure was 370 kPa and 1 241 kPa respectively, the maximum von Mises stress of brain tissue was 3.66 kPa and 26.73 kPa respectively at the frontal lobe and left temporal parietal lobe, and the maximum principal strain of brain tissue was 0.021 and 0.116 respectively at the frontal lobe and left temporal parietal lobe. The linear fracture occurred at the left posterior skull of the coronary suture. The damage evaluation indicators of the simulation results of the two cases exceeded their damage threshold, and the predicted craniocerebral injury sites and fractures were basically consistent with the results of the autopsy. CONCLUSIONS: The FEM can quantitatively evaluate the degree of blunt craniocerebral injury. The FEM combined with traditional method will become a powerful tool in forensic craniocerebral injury identification and will also become an effective means to realize the visualization of forensic evidence in court.

Isolated comminuted fracture of the cricoid cartilage and narrowing of the airway after a traumatic blunt injury of the neck: a case report.

BACKGROUND: Blunt trauma to the anterior of the neck may compromise the vital structures like major blood vessels, trachea, larynx, pharynx, thyroid, spine, esophagus, and the cricoid. Laryngeal trauma is rare and accounts for 1% of all neck blunt traumas. Cricoid trauma is also very rare and accounts for half of the laryngeal traumas, and the diagnosis is frequently missed. CASE PRESENTATION: A 43-year-old man, with blunt neck trauma after being hardly hit by a crane lifting hook, was referred to the Shahid Beheshti Hospital. The patient complained of dysphonia (hoarseness) and dyspnea. The CT scans showed a comminuted fracture of the left anterior arch of the cricoid cartilage with left-sided mucosal thickening, inflammation, and edema which was extended to the glottis, causing a narrowing of the airway. Direct fiber-optic laryngoscopy revealed swelling and congestion in the epiglottis and swelling at the level of the left vocal cord. CONCLUSION: This case report highlights the conservative treatment of isolated cricoid cartilage fracture in the setting of low-energy blunt trauma. The patient was clinically stable and treated conservatively with oxygen therapy and silence therapy (complete silence).
