Surgical treatment of peri-implant fracture with plate-on-plate technique: a case report

Due to the increased life expectancy and exposure to high-energy traumas, there has been a rise in the demand for surgical treatment using internal fixation, and consequently, an increase in refractures. Despite the growing discussion around peri-implant fractures, there is still little discussion addressing periplate fractures. This report presents a case using the plate-on-plate technique where the fracture is addressed while maintaining the previous fixation material by placing a locked plate above the previously existing material. This case involves a 54-year-old man with a peri-implant diaphyseal fracture of the distal third of the left femur after a motorcycle versus car collision. The patient underwent surgical treatment with a steel locking condylar plate, maintaining the previous fixation material through the plate-on-plate technique. Subsequently, fracture consolidation and functional range of motion were evidenced. Thus, in line with studies, the plate-on-plate technique proved to be an effective alternative for peri-implant fractures, allowing an approach with lower morbidity and mortality and reducing the risks of surgical complications; however, it requires studies with a higher level of epidemiological evidence.

Distinguishing injury patterns in fatal falls from heights versus pedestrian impacts: an autopsy study for differential diagnosis in ambiguous cases.

This study investigated the injury patterns associated with fatal falls from heights compared to individuals struck by cars, aiming to enhance the differential diagnosis in ambiguous cases, where it is unclear whether the body fell from nearby building or was left on the street following a road traffic incident. A retrospective review of comprehensive forensic reports from the Institute of Legal Medicine of the University of Rome "Tor Vergata" between 2012 and 2023 was conducted. The analysis included 232 cases, gathering data on internal organ injuries, skeletal fractures, external skin injuries, as well as pleural, peritoneal, and pericardial effusions. Bilateral lung injuries were significantly more common in falls from height (33.3%) compared to pedestrians (13.6%, p < 0.001). Liver injuries also occurred more frequently in fall victims (49.6%) than in pedestrians (28.2%, p < 0.001). Skull fractures were more frequent in falls from height (68.2%) versus individuals struck by cars (55.3%, p = 0.044), while unilateral leg fractures were more common in pedestrians (28.2%) compared to fall victims (16.3%, p = 0.029). External injuries, notably to the head and legs, were more frequent in pedestrians. The "Total Injured Skin Area" analysis revealed a significant discriminative power with an optimal cut-off of 84.2cm², suggesting that injuries exceeding this threshold may be indicative of a pedestrian road fatality.

Sacred journeys and pilgrimages: health risks associated with travels for religious purposes.

Pilgrimages and travel to religious Mass Gatherings (MGs) are part of all major religions. This narrative review aims to describe some characteristics, including health risks, of the more well known and frequently undertaken ones. A literature search was conducted using keywords related to the characteristics (frequency of occurrence, duration, calendar period, reasons behind their undertaking and the common health risks) of Christian, Muslim, Hindu, Buddhist and Jewish religious MGs. About 600 million trips are undertaken to religious sites annually. The characteristics varies between religions and between pilgrimages. However, religious MGs share common health risks, but these are reported in a heterogenous manner. European Christian pilgrimages reported both communicable diseases, such as norovirus outbreaks linked to the Marian Shrine of Lourdes in France, and noncommunicable diseases (NCD). NCD predominated at the Catholic pilgrimage to the Basilica of Our Lady of Guadalupe in Mexico, which documented 11 million attendees in one week. The Zion Christian Church Easter gathering in South Africa, attended by about 10 million pilgrims, reported mostly motor vehicles accidents. Muslim pilgrimages, such as the Arbaeen (20 million pilgrims) and Hajj documented a high incidence of respiratory tract infections, up to 80% during Hajj. Heat injuries and stampedes have been associated with Hajj. The Hindu Kumbh Mela pilgrimage, which attracted 100 million pilgrims in 2013, documented respiratory conditions in 70% of consultations. A deadly stampede occurred at the 2021 Jewish Lag BaOmer MG. Communicable and NCD differ among the different religious MGs. Gaps exists in the surveillance, reporting, and data accessibility of health risks associated with religious MGs. A need exists for the uniform implementation of a system of real-time monitoring of diseases and morbidity patterns, utilising standardised modern information-sharing platforms. The health needs of pilgrims can then be prioritised by developing specific and appropriate guidelines.

Traumatic Intracranial Intrusion of the Mandibular Condyle in the Middle Fossa: A Rare Case Report

AbstractThe displacement of the condyle into the middle cranial fossa after a high kinetic trauma represents a rare and low prevalence situation in the clinical routine of the maxillofacial surgeon. After a motorcycle accident, a 19-year-old male patient evolves with displacement of the left mandibular condyle to the middle cranial fossa, requiring surgical management in association with the neurosurgical team for repositioning and reconstruction of the glenoid fossa. After craniotomy, the condyle was visualized in the middle fossa. After bone disimpaction with a driller, the condyle was repositioned and the glenoid fossa was reconstructed with a titanium mesh. After 12 months of follow-up, no neurological or functional sequela was observed. The displacement of the mandibular condyle to the cranial fossa is rarely reported in the literature. It requires a multidisciplinary team for its management. Long-term follow-up is also necessary, especially in young patients.

Measurement of tiny moment of inertia based on flexure hinge for automobile collision testing

Abstract The moment of inertia is a critical parameter for determining the motion state of an object and achieving precise control. At present, measurement techniques for the moment of inertia of large and heavy objects (greater than 0.5 kgm2) are very mature. However, it is still a challenge to achieve high precision for smaller objects (less than 0.5 kgm2). In this paper, a measuring device based on flexure hinges is proposed to achieve high-accuracy measurement of tiny moments of inertia, without additional friction. A theoretical model of measurement is developed and optimised to obtain the rotational inertia by measuring swing periods. The experimental results show that the maximum load of the device is 20 kg, and the resolution reaches 4 × 10−5 kgm2. For a 5 kg head model, the moment of inertia was measured to be 0.011 58 kgm2, with a combined standard uncertainty of 0.000 29 kgm2.

Marijuana Legalization and Truck Safety

ABSTRACTMany states have legalized medical and recreational marijuana use in the past decade, which has potential consequences for roadway safety. Using a state‐level panel of heavy truck crash statistics from 2005 to 2021 and a difference‐in‐difference estimation strategy, we test whether legalization has affected crash rates. Our results show that legalization does not increase crash rates on average; however, responses are heterogeneous across states, with Colorado, New Jersey, and Washington (state) showing crash reductions, while Connecticut and Virginia saw crashes increase. These results suggest that marijuana legalization does not have a straightforward relationship with heavy truck accidents, warranting continued research and policy scrutiny.

Bus drivers’ anger and anger expression in driver–passenger conflicts

Bus driver anger due to passenger misbehavior may lead to serious bus accidents, yet there are no mature tools available to capture bus driver reactions during driver–passenger conflicts. The bus driver anger scale (BDAS) and the bus driver anger expression inventory (BDAX) were developed to measure the anger levels and expressions of drivers in such conflicts. A bus driver anger model was developed based on 400 questionnaires in Changsha, China. The findings indicate that drivers are most likely to be angered by passenger violations and quarrels among passengers. Drivers irritated by passenger irregularities tend to employ personal aggressive expression or adaptive/constructive expression. Disputes among passengers may lead drivers to resort to unreasonable methods of venting their emotions. Moreover, passengers’ rude behaviors can trigger bus drivers’ aggressive personal expressions. Therefore, it is necessary to establish passenger regulations and encourage drivers to express their anger reasonably in driver–passenger conflicts.

PCL injury following high energy trauma: associated injuries and postoperative complications “insights from a national registry study”

PurposeThe posterior cruciate ligament (PCL) is a vital knee stabilizer. While PCL injuries are rare, high-energy traumas can lead to total ruptures, with accompanying injuries requiring surgery. This study aims to investigate the demographics, concomitant injuries, and postoperative complications of patients who underwent PCL reconstruction due to high-energy trauma in a large patient sample.MethodsPatients who underwent PCL reconstruction from 2016 to 2022 were retrospectively evaluated using data from a nationwide personal health recording system. Patient demographics, injury mechanisms, associated fractures, soft tissue injuries, and postoperative complications were collected from patient notes, clinical visits, and surgical notes. Individuals with a PCL injury following high-energy trauma (car accident, falls from height, motorcycle accident) with a minimum follow-up of 1 year were included in the study.ResultsThe study included 416 patients with a mean age of 32.4 years. Isolated PCL injuries (n = 97, 23.3%) were observed less frequently than multiple-ligament injuries (n = 319, 76.7%). Most cases were treated with single-stage surgery (86.8%), while staged surgeries were performed in a minority of cases (13.2%). There was no relationship between trauma mechanisms and multiple-ligament involvement, accompanying injuries, or postoperative complications. Surgeries following car accidents were more likely to occur as staged surgeries (p = 0.014). Additionally, the complication rates for staged surgeries and younger patients (≤ 18 years) were significantly higher (p = 0.009).ConclusionHigh-energy trauma-induced PCL injuries are often associated with severe concurrent knee injuries with multiple ligament involvement. PCL reconstructions following car accidents are more likely to be staged. These findings highlight the importance of careful consideration in managing these cases to minimize complications, particularly in younger age groups.Level of evidenceLevel III.

Clinical and radiographic predictors for angiography in pelvic trauma: An analysis of 1703 patients

IntroductionPatients who present with hemorrhage from pelvic fractures have an increased risk of mortality with prolonged time to intervention. Identifying risk factors associated with hemorrhage can expedite treatment. In this study we explore clinical and radiographic predictors for angiography in trauma patients with pelvic fractures. MethodRetrospective, single-center review between 2009 and 2019 at a level 1 trauma center of all trauma patients with pelvic fractures. We excluded patients who died prior to arrival or in the trauma bay who did not undergo computed tomography (“CT”). Finalized attending descriptions of CT findings were reviewed, including size of hematomas, and presence of extravasation. Chi-square, Mann-Whitney U and multi-variate regressions were performed. ResultsWe analyzed 1,703 trauma patients with pelvic fractures. Most common mechanisms of injury included MVC (45 %), fall (27 %) and motorcycle accident (12 %). 48 % (819/1703) of patients had pelvic hematomas on CT scan. 17 %(138/819) of patients with a hematoma also had evidence of extravasation. Significant predictors for extravasation on CT included large hematoma on CT, AIS extremity ≥2, binder placement, increased ISS, HR, and decreased GCS and SBP (p < 0.005). Significant predictors for angiography were similar, including AIS extremity ≥2, binder placement, presence of moderate and large hematoma and active extravasation on CT (p < 0.01). Stepwise logistic regression model incorporated ISS, HR, AIS extremity score, binder placement, and contrast extravasation with an AUC = 0.9345. ConclusionIn this large retrospective review of traumatic pelvic fractures, specific clinical and radiographic factors were significantly associated with pelvic hematomas, extravasation and/or need for angiography. Future collaborative work with orthopedics and interventional radiology is planned to better triage pelvic fracture patients and identify those at risk for bleeding that require earlier intervention.

Comparative Analysis of Traumatic Brain Injury Severity in Motorcycle and Car Accident Victims Treated at Korle-Bu Teaching Hospital

Abstract Background: Traumatic brain injury (TBI) is one of the common causes of long-term disabilities, with about 10 million deaths annually. Objectives: Our aim is to compare the severity and outcomes of TBI between motorcycle and car accident victims. Materials and Methods: A prospective cohort study focusing on TBI patients. Data were collected from patients on admission at Korle-Bu Teaching Hospital (KBTH). Road traffic accident patients attending KBTH were recruited consecutively. Data collected included demographics, injury severity score (ISS), Glasgow coma scale (GCS), Marshall’s computed tomography (CT) grading, and Glasgow outcome scale-extended. We employed descriptive summaries for all variables. Mann–Whitney U and Kruskal–Wallis tests were used in comparing severity. Results: A total of 164 individuals were enrolled, with males comprising (73.8%) and a study average age of 33.2 years. Accidents involved cars and motorcycles almost equally. The GCS revealed 43.9% of injuries to be mild, and ISS indicated severe injuries in 49.4% of cases. CT showed grade 2 injuries per Marshall’s classification and no significant differences in injury patterns. Nonsurgical treatment predominated, and a higher proportion of motorcycle cases required surgery. There were no significant differences in mortality or disability. The average hospital stay was 11.26 days, with 57.9% of deaths occurring within 72 h. Car accident survivors and pedestrians experienced longer days to mortality. Conclusion: Across groups, the severity of TBIs showed a substantial proportion of participants with severe injuries, although no significant differences were observed between groups. The findings highlight the need for preventive measures and trauma care strategies to mitigate the impact of TBIs, particularly among high-risk demographics and road user categories.

Massive bone defect in open leg fracture: A case report

Open fractures with massive defects are likely the most challenging conditions to manage in traumatology, particularly due to the scarcity of cases described in the literature where limb preservation was feasible. This report illustrates the management of an open fracture with a massive bone defect in which the physicians recurred to amputation after an attempt to preserve the patient’s quality of life through initial reparative treatment. A 57-year-old male presented with an open fracture with a de novo 25-cm bone defect following a motorcycle accident. Despite the large laceration, the injury presented with a relatively conserved surrounding muscular tissue; the distal two-thirds of the tibia were missing; yet, no neurovascular damage was documented. The patient was managed with a temporary external fixator and antibiotic-loaded cement spacer. Due to the patient’s desire to ride his motorcycle again, the authors performed a custom-made tibiotalar nailing arthrodesis 22 weeks later. This case presented the risk of infection and low quality of life, which led to amputation 74 weeks after the nailing procedure was performed. The treatment remains challenging in cases of massive bone defects and a relatively preserved biological-functional environment, and efforts should be made to develop tailored strategies. Although individualized care provides patients with time and hope, it might still fail to guarantee a decent quality of life and risks being a temporary solution before reverting to amputation.

Generalization of cut-in pre-crash scenarios for autonomous vehicles based on accident data

The utilization of high-risk test cases constitutes an effective approach to enhance the safety testing of autonomous vehicles (AVs) and enhance their efficiency. This research paper presents a derivation of 2052 high-hazard pre-crash scenarios for testing autonomous driving, which were based on 23 high-hazard cut-in accident scenarios from the National Automobile Accident In-Depth Investigation System (NAIS) through combining importance sampling and combined testing methods. Compared to the direct combination of the original distribution after sampling, the proposed method has a 2.92 times higher crash rate of 69.32% for the test case set in this paper. It also has a 5.8 times higher rate of triggering Automatic Emergency Braking (AEB), improving hazardous scenario coverage. Using the proposed method, the generated parameters of the cut-in accident scenario test set were compared with those of the cut-in test scenarios included in existing Chinese autonomous driving test protocols and standards. The velocity of the ego-vehicle obtained using the proposed method matched those in the existing protocols, whereas the velocity, time gap, and time to collision of the target vehicle were significantly lower than those existing protocols indicating scenarios obtained from accident data can enrich the selection of testing scenarios for autonomous driving.

Testing and evaluation of light clothing properties used in fire and rescue service units

In the testing room for examination products of the Fire Engineering and Expert Institute (FEEI) of the Ministry of the Interior of the Slovak Republic in Bratislava, the Slovak National Accreditation Service SNAS has granted accreditation. Accredited testing room with identification number no. S-084 performs tests applied in the field of personal protective equipment. The goal is to specify, determine, and, above all, verify the selected characteristics for emergency clothing (light emergency clothing - LEC) used by firefighters and rescuers in the Fire and Rescue Service units to determine the conditions for procurement and quality control of the LEC supplied. The results obtained during the examination of the properties of light emergency clothing will be used in the next steps of the research of the Product Assessment Department (PAD) FEEI of the Ministry of the Interior of the Slovak Republic. In contrast, individual parameters can be used to design new LEC. The basic meaning and purpose of any protective means are to protect a person who intervenes in a dangerous environment contaminated with chemical, biological or radioactive substances, for example, in industrial accidents connected with the release of dangerous substances (HAZMAT), in accidents of vehicles transporting HAZMAT and natural disasters or fires of various nature. Protecting from the external environment is one of the favourable inherent properties of personal protective work equipment (PPE).

Subclavian arterial rupture due to blunt trauma injury: A case report.

Subclavian arterial injury due to blunt trauma is rare but can have devastating outcomes. Massive hemorrhage or limb ischemia might develop depending on the extent of damage, and open repair might be necessary to salvage the limb. However, life-saving treatments should be prioritized in critically unstable patients. A 21-year-old male patient who was transferred to our trauma center following a motorcycle accident. Abdominal and chest computed tomography (CT) revealed right renal injury and massive hemothorax with several rib fractures in the right chest. Right renal injury with multiple extravasations and right 8th intercostal arterial injury were detected during angiography. Emergent exploration with lateral thoracotomy was performed to manage right hemothorax. Pulsating bleeding from the thoracic roof observed in the operative field suggested a subclavian arterial injury. The unstable vital signs did not recover despite massive transfusion, and his right arm had already stiffened. Therefore, endovascular approach was adopted and the second portion of the right subclavian artery was embolized using microcoils and thrombin. Postoperative intensive care unit management performed to resuscitate patient from multiorgan failure included continuous renal replacement therapy (CRRT). After confirming the demarcation lines, transhumeral amputation of the right arm was performed on admission day 12. The patient recovered from multiorgan failure for more than 3 weeks after the accident; however, the patient survived. Limb salvage, albeit critical for quality of life, is not possible in some cases where life-saving measures require its sacrifice. In these cases, quick decision-making by the surgeon is paramount for patient survival. As illustrated in this case, endovascular approaches should be considered less invasive measures to save the patient's life.

Fault diagnosis method for lithium-ion batteries based on the combination of voltage prediction and Z-score

ABSTRACT Safety accidents in new energy electric vehicles caused by lithium-ion battery failures occur frequently, and the timely and accurate diagnosis of failures in battery packs is crucial. Voltage, as one of the primary characterization parameters of lithium-ion battery malfunctions, is widely utilized in fault diagnosis. This article proposes a lithium-ion battery fault diagnosis method Fault diagnosis method based on the combination of voltage prediction and Z-score. Firstly, the stable trend component is extracted from the battery voltage data using variational mode decomposition, which avoids the influence of noisy signals and random perturbations to the greatest extent. Subsequently, a TCN-BiLSTM-attention model is designed to estimate the average voltage of the battery under normal conditions. Finally, the residuals between the estimated and individual cell voltages are calculated, and the Z-score is utilized to locate and judge whether the battery is caused by the occurrence of a fault. Through verification with real vehicle data and experimental data, the proposed method effectively identifies abnormal battery cells. Compared to the correlation coefficient method, this approach exhibits superior applicability.

Quality of Life and Spiritual Health in Motorcycle Accident Survivors: An Analysis Using the SF-36 Questionnaire and Spiritual Scale

Abstract Introduction Motorcycle traffic accidents rate remained high in Taiwan letting post-trauma care an imperative issue. This study investigates the spiritual, psychological, and physical impacts of motorcycle traffic accidents in Taiwan, focusing on the role of the Injury Severity Score (ISS) in influencing quality of life (QOL) and spiritual well-being outcomes, aiming to enhance holistic recovery strategies for trauma survivors. Methods A prospective study was conducted from April 2022 to March 2024 in a level I trauma center. Patients aged 20 and above with trauma from motorcycle accidents were enrolled and divided into major (ISS ≥ 16) and non-major (ISS &lt; 16) trauma groups. QOL and spiritual health were assessed using 36-item short-form general health survey measures (SF-36) and spiritual scale before discharge and six months later. Results Of 98 patients, we observed significant post-discharge declines in both physical and mental QOL scores, regardless of ISS. However, spiritual scores improved significantly after discharge, with notable enhancements in interpersonal relationships and adversity transcendence observed in patients with ISS &lt; 16, but not in those with ISS ≥ 16. SF-36 analysis revealed that non-religious groups experienced significant declines in mental health scores post-discharge, unlike religious groups, which remained stable. Additionally, religious individuals showed significant post-discharge improvements in interpersonal relationships and adversity transcendence, while non-religious showed no improvement. This suggests a beneficial link between religious adherence and enhanced spiritual well-being. Conclusion Motorcycle accidents reduce QOL and heighten spiritual needs for survivors, regardless of accident severity categorized by ISS score. Integrating spirituality into rehabilitation processes can positively impact overall well-being. Holistic care, addressing physical, psychological, social, and spiritual needs, is vital for optimizing long-term recovery and improving prognosis in trauma survivors, especially in regions with high rates of traffic accidents like Taiwan.

Omentomyelopexy for the Treatment of a Persistent Lumbar Pseudomeningocele: A Case Report With Technical Note.

Pseudomeningoceles are extradural accumulations of cerebrospinal fluid. In most cases, they appear as a complication of spinal operations. Omentomyelopexy is a surgery in which an autologous omentum flap is implanted over the dural opening. We describe a case of persistent pseudomeningocele treated with omentomyelopexy. A 37-year-old man sustained a T12-L1 AO B3 fracture during a motorcycle accident. He underwent posterolateral fusion and then neurological rehabilitation. Two years later, however, his condition worsened, and he experienced progressive weakness-he was diagnosed with an intramedullary cyst, which was treated with laminectomy, arachnolysis and cystotomy. A pseudomeningocele developed afterward, and the patient underwent multiple reoperations in the following years, none of which were effective. Omentomyelopexy, a complex procedure aimed to facilitate cerebrospinal fluid absorption and subsequent formation of a permanent membrane, was offered to the patient as a "last resort." After undergoing omentomyelopexy, his pseudomeningocele resolved. Although it should be reserved for exceptionally pertinent cases, omentomyelopexy is a viable option for managing persistent pseudomeningocele. However, further research is needed to better understand the effects and benefits of omentomyelopexy in this context.
