In Germany, blast and gunshot injuries are uncommon but complex injury entities. Due to the global political situation, terrorist attacks, accidents, or acts of violence, these injuries are potentially part of the reality of care for every anaesthetist, surgeon, and emergency physician. In principle, this type of injury should be treated in a trauma centre with appropriate expertise, but the knowledge of basic treatment principles is necessary for all practitioners. First, emergency training and surgical simulation courses should be carried out regularly to remain confident in emergency surgery techniques and treatment strategies. In addition, minimally invasive methods are predominantly used in elective surgery, meaning that the routine of primarily open surgery is missing. Therefore, it is important that surgeons learn surgical steps to be better prepared for emergency open surgery.The critical principle of damage control surgery is stopping the bleeding and the contamination and preventing a delay in intensive care therapy. For penetrating thoracic trauma, a chest tube must be inserted. If the patient is hemodynamically unstable, an anterolateral thoracotomy should be performed to achieve bleeding control, e.g., by cross-clamping the aorta or pulmonary hilum. For stable patients, a video-assisted thoracoscopy might be an option.The standard abdominal approach is the median laparotomy. Bleeding control can be achieved by hiatal aortic cross-clamping and packing of the abdomen, followed by a systematic exploration. If necessary, a laparostomy must be established. Moreover, if chest injuries are ruled out, the resuscitative endovascular balloon occlusion of the aorta (REBOA) can be considered as a bridge to surgery.Whether projectiles, fragments, or shrapnels require removal depends on the location and the potential complications of tissue dissection. Penetrating injuries due to blasts and gunshots are always contaminated., Competing Interests: Erklärung zu finanziellen Interessen Forschungsförderung erhalten: nein; Honorar/geldwerten Vorteil für Referententätigkeit erhalten: nein; Bezahlter Berater/interner Schulungsreferent/Gehaltsempfänger: nein; Patent/Geschäftsanteile/Aktien (Autor/Partner, Ehepartner, Kinder) an Firma (Nicht‐Sponsor der Veranstaltung): nein; Patent/Geschäftsanteile/Aktien (Autor/Partner, Ehepartner, Kinder) an Firma (Sponsor der Veranstaltung): nein Erklärung zu nichtfinanziellen Interessen Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

The severity and extent of gunshot and blast injuries are often misjudged due to a lack of specialist knowledge. The aim of this article is to outline the characteristics of gunshot and blast injuries, including emergency diagnostics and initial surgical treatment.Due to multiple high-energy penetrating injuries, barotrauma, or blunt trauma, affected patients are usually polytraumatized, with multiple organ damage and an average Injury Severity Score (ISS) of > 36. In addition to the complexity of the wounds, they are characteristically severely contaminated. After pre-hospital treatment, life-threatening injuries and conditions should be identified and initially treated in the trauma room phase. The procedure should be based on a standardized, internal hospital emergency medical and emergency surgical algorithm. Damage control surgery can then be used to treat acutely life-threatening complications of gunshot and blast injuries in order to prevent the fatal triad and the occurrence of further early complications. Examples of interventions include debridement and decontamination, fracture stabilization (external fixators and splints), surgical decompression (skull, thorax, compartment syndromes) and surgical hemostasis., Competing Interests: Erklärung zu finanziellen Interessen Forschungsförderung erhalten: nein; Honorar/geldwerten Vorteil für Referententätigkeit erhalten: nein; Bezahlter Berater/interner Schulungsreferent/Gehaltsempfänger: nein; Patent/Geschäftsanteile/Aktien (Autor/Partner, Ehepartner, Kinder) an Firma (Nicht‐Sponsor der Veranstaltung): nein; Patent/Geschäftsanteile/Aktien (Autor/Partner, Ehepartner, Kinder) an Firma (Sponsor der Veranstaltung): nein Erklärung zu nichtfinanziellen Interessen Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

The treatment strategy for blast injuries is closely linked to the clinical outcome of blast injury casualties. However, the application of military surgery experience to blast injuries caused by production safety accidents is relatively uncommon. In this study, the authors present 2 cases of blast injuries caused by one gas explosion, both cases involved individuals of the same age and gender and experienced similar degree of injury. The authors highlight the importance of using a military surgery treatment strategy, specifically emphasizing the need to understand the concept of damage control and disposal. It is recommended that relevant training in this area should be strengthened to improve the clinical treatment of such injuries. This study provides a valuable reference for healthcare professionals dealing with blast injuries., (Copyright © 2024. Published by Elsevier B.V.)

Blast and gunshot-induced penetrating traumatic vascular injuries represent a significant portion of patients with vascular trauma in countries where there are higher rates of war-related violence. These injuries are especially challenging in resource-limited countries due to early diagnosis and transfer delays. This report aimed to present our experience regarding the surgical management and outcome of such injuries at a major referral vascular surgery centre in the country. A retrospective descriptive review of 326 patients with blast and gunshot-induced penetrating traumatic vascular injuries managed during a five-year period between April 2018 and April 2023. The demographics, mechanism of injury, type of vascular injury, Anatomical location, time to the operation, length of hospital stay, amount of blood products given, concomitant neuroskeletal injuries, development of Vascular injury associated acute kidney injury, surgical procedures performed and patient outcome were reviewed. In this study, 326 patients with 445 vascular injuries fulfilled the inclusion criteria. Most of the patients were male 92.3%, and the mean age was 28.3 ± 9.9 years. The gunshot mechanism of vascular injury was implicated in 76.1% of the injuries, and explosive-induced injury was 78 (23.9%). 193 (59.2%) of the patients had isolated arterial injuries, 117 (35.9%) patients had combined arterial and venous injuries while 18 (4.9%) patients had isolated venous injuries. The most commonly injured arteries were the femoral artery, followed by Brachial and popliteal artery injuries (26.1%, 23.5% and 19.4%, respectively). The median time to revascularization was 8.8 ± 8.7 h. 46.8% of the patients had Concomitant fractures, while 26.5% had Concomitant nerve injuries. Only three patients had temporary non-heparin-bound shunts during their arrival. The most common surgical intervention in arterial injuries was reversed saphenous vein graft 46.1%. The mortality was 5.8% and 7.7% of the patients needed secondary amputation. The majority of wartime arterial injuries are a result of Blast and gunshot vascular injuries. Frequent need for autologous vein grafts should be considered to manage such injuries. Results are encouraging despite delays in intervention; therefore, all viable limbs should be revascularized, keeping in mind the long-term functionality of the limb., (© 2024. The Author(s).)

Background: During the wars in Afghanistan and Iraq most injuries to service members involved the musculoskeletal system. These wounds often occurred around joints, and in some cases result in traumatic arthrotomy-a diagnosis that is not always clear, especially when there is no concomitant articular fracture. The aim of the present study is to evaluate the diagnosis and treatment of peri-articular blast injuries without fracture., Methods: The study cohort included 12 consecutive patients (12 involved extremities) who sustained peri-articular blast wounds of the extremities without fractures. The diagnosis of penetrating articular injury was based on clinical examination, radiographic findings, or aspiration. A peri-articular wound was defined as any wound, or radio-opaque blast fragment, within 5 cm of a joint. The New Injury Severity Score (NISS) was calculated for each patient. Four patients had upper, and 8 patients had lower extremity injuries. Nine of 12 patients had joint capsular penetration and underwent joint irrigation and debridement., Results: Two patients had retained intra-articular metal fragments. One patient had soft tissue blast wounds within 5 cm of a joint but did not have joint capsule penetration. There were no significant differences (p = 0.23) between the distribution of wounds to upper versus lower extremities. However, there were a significantly greater number of blast injuries attributed to Improvised Explosive Devices (IEDs) than from other blast mechanisms (p = 0.01)., Conclusion: Extremity blast injuries in the vicinity of joints involving only soft tissues present a unique challenge in surgical management. A high index of suspicion should be maintained for joint capsular penetration so that intra-articular injuries may be appropriately treated., (© 2024.

Despite available armored personal protection in troops, the incidence of abdominal wounds in modern wars is 6.6-9.0%. Of these, penetrating abdominal injuries comprise 75-80%. Thoracoabdominal injuries occupy a special place with incidence up to 88%. We present the first case of the "Koblenz algorithm" in the treatment of a patient with mine explosion wound, combined injury of the head, limbs, thoracoabdominal trauma, widespread peritonitis, small intestinal obstruction and septic shock in a military hospital. This algorithm was implemented under import substitution considering the peculiarities of abdominal adhesive process in a patient with thoracoabdominal wound. This case demonstrates the advantage of this algorithm for patients with severe combined wounds of the chest and abdomen complicated by diffuse purulent peritonitis. Clinical status of these patients does not allow not only open laparostomy, but also "classical" redo laparotomies.

An explosion is a process that rapidly releases a huge amount of energy in the form of heat, kinetic energy, and high-pressure shock waves. Since the organ of hearing is most susceptible to pressure changes, damage to the sound-conducting or sound-receiving systems is inevitable in case of an explosive injury. This article examines the mechanism of formation of explosive injuries of the middle and inner ear in children and adolescents, the features of diagnosis and tactics of surgical reconstructive treatment of explosive ear injuries based on the data available in the scientific literature and their own experience.

In this study, the authors aimed to share their experience with 46 patients who were wounded due to terrorism and war in Somalia. The authors also evaluated the etiological diversity of terror-related and war-related injuries. The study included 46 patients treated at the 150-bed Turkey-Somalia Tertiary Hospital between 2019 and 2021. The authors reviewed medical records including data regarding age, sex, trauma etiology, and type of fracture and trauma. For all patients, surgical technique and plate and screw applications were recorded. The authors also assessed complications and outcomes for the patients. The study included 5 women (10.9%) and 41 men (89.1%). The mean age was 30.36 years. It was found that 2 patients (4.35%) presented to the emergency department with stab injuries, 33 patients with blast injuries from improvised explosive devices (71.73%), and 11 patients with firearm injuries. There were 31 patients with maxillary and mandibular fractures, 17 of which had both maxillary and mandibular fractures. There were 14 patients with maxillary fracture alone, including 3 patients with tripod fracture and 7 patients with inferior and lateral rim fracture. There was a mandibular fracture in 17 patients, including 5 patients with parasymphysis fracture, 7 patients with ramus fracture, and 5 patients with multifocal comminuted fracture. It is a challenging process to treat terror-related injuries in our tertiary hospital in Somalia, where all resources are imported from foreign countries. In such settings, authorities should make protective equipment obligatory to prevent civil and military casualties. Trauma hospitals and experienced trauma surgeons should be available., (Copyright © 2023 by Mutaz B. Habal, MD.)

Introduction: Operations Iraqi Freedom and Enduring Freedom saw higher rates of combat ocular trauma (COT) than any past U.S. conflict. The improvised explosive device, the signature weapon of the conflicts, as well as improved personal protective equipment and combat medical care all attributed to COT being the fourth most common injury sustained by wounded U.S. service members. This review describes the epidemiology, mechanisms, and treatment patterns and discusses the relationship of traumatic brain injuries (TBIs) to ocular injuries sustained by U.S. service members during the War on Terror., Materials and Methods: A mixed-methods review of the literature was conducted by extracting data from PubMed, Embase, and Cochrane research databases between December 15, 2020, and January 25, 2021, using the COVIDENCE review management software., Results: Of 827 articles for review, 50 were deemed relevant. Articles were separated using the Birmingham Eye Trauma Terminology into open globe, closed globe, mixed/injury management only, and TBI. Seventeen articles were found to discuss data pertaining to particular databases. Overall, six articles discussed open-globe injuries in the setting of overall COT with a reported rate of 38-64%. Three articles discussed closed-globe injuries in the context of overall COT with a rate of 39-47%. Numerous articles discussed the relationship between COT and TBI. Within the Walter Reed Ocular Trauma Database, 40% of patients with ocular trauma had concomitant TBI. Additionally, the visual sequelae of ocular trauma ranged from 9% to 50% among reporting studies. Other ocular injury patterns receiving attention include neuro-ophthalmic and oculoplastic injuries. By far the most common mechanism of COT was blast injury (64-84%), with improvised explosive devices (IEDs) accounting for 51-69% of ocular injuries. Among the large reporting databases, 41-45% of COT required surgical treatment with an overall enucleation rate of 12-17%., Conclusions: The Global War on Terrorism saw an evolution in the types of ocular injuries sustained by U.S. service members compared to previous conflicts. The widespread use of IEDs led to injury patterns not encountered in previous conflicts. Weapons of today utilize blast and shrapnel as the mechanism for destruction. Sequelae such as TBIs and complicated head and neck trauma have pushed innovation in the field of ophthalmology. Improvements in medical technology and personal protective equipment have resulted in not only survival of previously life-threatening injuries, but also a greater chance of severe loss of vision. By analyzing ocular injury data from the trauma literature, improvements in education and training can lead to improvements in point-of-injury care and eye protection for the next generation of warfighters., (© The Association of Military Surgeons of the United States 2022.

Objective: Lower extremity junctional injuries due to explosive blasts are among the most lethal sustained on the battlefield. To help reduce the effects of junctional and perineal trauma from this injury mechanism, a tiered Pelvic Protection System (PPS) was fielded during the war in Afghanistan., Methods: Thirty-six patients with known PPS status who sustained traumatic above knee amputations, with and without perineal injuries, were identified from an operative amputation registry in Helmand Province, Afghanistan, spanning a 12-month period., Results: In Group 1 patients with above knee amputations who wore some tier of the PPS system, 47% (8 of 17) sustained junctional/perineal injuries. Of the patients in Group 2 who wore no PPS, 68% (13 of 19) sustained perineal injuries associated with proximal amputations. Overall, these differences were statistically significant (p = 0.0115)., Conclusion: Use of a PPS may reduce the risk of having severe perineal and lower extremity junctional injury in service members sustaining traumatic above knee amputations from an explosive blast., Competing Interests: Declaration of Competing Interest I have no conflict or declaration of interest., (Copyright © 2023 Elsevier Ltd.

Blast injuries are both complex and rare in the civilian population. This combination can often lead to missed opportunities for early, effective intervention. This is a case report of a 31-year-old male who suffered a lower extremity blast injury while using an industrial sandblaster. This blast injury presented as a closed degloving, or Morel-Lavallee lesion, which can easily be mistreated and lead to infection and further disability. Following assessment, identification, and confirmation of the Morel-Lavallee lesion via radiographic imaging, this patient underwent debridement surgery, wound vac therapy, and antibiotic treatment before being discharged home with no major physiologic or neurologic deficits. The purpose of this report is to highlight the importance of assessing for closed degloving injuries when presented with blast injury traumas in the civilian trauma setting, and outlines the process utilized for assessment and treatment.

Introduction: Pelvic fractures are a common occurrence in combat trauma. However, the fracture pattern and management within the most recent conflicts, i.e. Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF), have yet to be described, especially in the context of dismounted complex blast injury. Our goal was to identify the incidence, patterns of injury and management of pelvic fractures., Methods: We conducted a retrospective review on all combat-injured patients who arrived at our military treatment hospital between November 2010 and November 2012. Basic demographics, Young-Burgess fracture pattern classification and treatment strategies were examined., Results: Of 562 patients identified within the study time period, 14% (81 of 562) were found to have a pelvic fracture. The vast majority (85%) were secondary to an improvised explosive device. The average Injury Severity Score for patients with pelvic fracture was 31±12 and 70% were classified as open. Of the 228 patients with any traumatic lower extremity amputation, 23% had pelvic fractures, while 30% of patients with bilateral above-knee amputations also sustained a pelvic fracture. The most common Young-Burgess injury pattern was anteroposterior compression (APC) (57%), followed by lateral compression (LC) (36%) and vertical shear (VS) (7%). Only 2% (nine of 562) of all patients were recorded as having pelvic binders placed in the prehospital setting. 49% of patients with pelvic fracture required procedural therapy, the most common of which was placement of a pelvic external fixator (34 of 40; 85%), followed by preperitoneal packing (16 of 40; 40%) and angioembolisation (three of 40; 0.75%). 17 (42.5%) patients required combinations of these three treatment modalities, the majority of which were a combination of external fixator and preperitoneal packing. The likelihood to need procedural therapy was impacted by injury pattern, as 72% of patients with an APC injury, 100% of patients with a VS injury and 25% of patients with an LC injury required procedural therapy., Conclusions: Pelvic fractures were common concomitant injuries following blast-induced traumatic lower extremity amputations. APC was the most common pelvic fracture pattern identified. While procedural therapy was frequent, the majority of patients underwent conservative therapy. However, placement of an external fixator was the most frequently used modality. Considering angioembolisation was used in less than 1% of cases, in the forward deployed military environment, management should focus on pelvic external fixation±preperitoneal packing. Finally, prehospital pelvic binder application may be an area for further process improvement., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Introduction: On August 4, 2020, a massive explosion of a warehouse holding 2,700 metric tons of ammonium nitrate took place in the port of Beirut, Lebanon. This incident, which is considered as one of the largest industrial disasters lead to the death of at least 220 people and more than 6000 injuries. Hospitals near the blast were damaged significantly which made it difficult to treat injured patients. The objective of this study is to report the epidemiology and characteristics of the injuries and their initial management that could be useful for healthcare workers and policymakers in case of a similar massive accident in the future., Materials and Methods: A retrospective study was conducted. All charts of patients admitted to the emergency room and outpatient clinics on the day of the blast and during the following 2 weeks were thoroughly reviewed. Due to initial chaos during triage, direct phone contact with patients was utilized in certain situations to confirm their identity or for further information. All acute injuries were recorded based on the region, severity, degree of emergency, initial and later management, type of injured organs, and surgical procedures., Results: A total of 159 patients presented to our facility. 153 patients presented to the ER on the same day of the blast. The mean age was 47.07 years and around 60% of the patients were males (n = 93). Most of the patients presented either from zone 1 (n = 67, 42%) or zone 3 (n = 68, 43%). The majority of injuries were secondary injuries due to glass (n = 131, 82.3%), with the head (34%) and upper extremities (31.2%) being most commonly affected. A total of 94 patients (62.6%) underwent a type of imaging and 64 patients (40.2%) had at least one surgery performed during their hospitalization in which 71% of the surgeries being related to the limbs., Conclusion: This study demonstrated a unique injury pattern due to this type of blast. Injuries were mostly due to glass shrapnel. Contrary to bomb blasts, most injuries were located in the head and upper extremities rather than on the lower extremities., (Copyright © 2022.

Purpose: Under-vehicle explosions caused by improvised explosive devices (IED) came to the public's attention during armed conflicts. However, IEDs are also used by criminals in the civilian setting. This study aimed to determine the pattern of injury, medical management, and outcomes of civilians injured during under-vehicle explosions caused by IEDs., Methods: This is a retrospective cohort study based on the Israeli National Trauma Registry of patients injured from under vehicle explosions caused by IEDs during 2006-2020. Injuries resulting from terror attacks and war were excluded. Descriptive statistics were used for data analysis., Results: During the study period, 58 incidents were recorded, resulting in 74 patients who arrived alive to the hospitals and 17 who died on scene. Seventy-one (95.9%) were male with a median age of 32 years (IQR 24-42). 42% were severely injured (ISS ≥ 16). There was an average of 2.4 injured regions per patient, with extremity injuries being the most common (70.3%). Face (34%), abdomen (28%), and chest (22%) injuries were frequent. 45% were immediately transferred to the operating theatre, and 72% underwent at least one operation. Orthopedic surgeries were the most common interventions. 27 amputations were performed., Conclusions: Injuries caused by under-vehicle IEDs in civilian settings differ from those caused by IEDs used during military conflicts or acts of terrorism: they are associated with fewer victims per incident, more severe injuries, more truncal injuries, and more lower extremity injuries requiring amputations. This can be attributed to the lack of personal and vehicle protection, and the different explosive types., (© 2021. Springer-Verlag GmbH Germany, part of Springer Nature.)

The tenets of neurosurgery worldwide, whether in the civilian or military sector, espouse vigilance, the ability to adapt, extreme ownership, and, of course, an innate drive for developing a unique set of technical skills. At a time in history when the complexity of battlefield neurotrauma climaxed coupled with a chronic shortage of military neurosurgeons, modernized solutions were mandated in order to deliver world-class neurological care to our servicemen and servicewomen. Complex blast injuries, as caused by an increased incidence of improvised explosive devices, yielded widespread systemic inflammatory responses with multiorgan damage. In response to these challenges, the "NeuroTeam," originally a unit of two neurosurgeons as deployed during Operation Desert Storm, was redesigned to instead pair a neurosurgeon with a neurointensivist and launched itself during two specialized missions in Operations Iraqi Freedom and Enduring Freedom. Representing a hybridized version of present-day neurocritical care teams, the purpose of this unit was to optimize neurosurgical care by focusing on interdisciplinary collaboration in an Echelon III combat support hospital. The NeuroTeam provided unique workflow capabilities never seen collectively on the battlefield: downrange neurosurgical capability by a board-certified neurological surgeon within 60 minutes from the point of injury paired with a neurocritical care-trained intensivist. This also set the stage for intraoperative telemedicine infrastructure for neurosurgery and optimized the ability to evaluate, triage, and stabilize patients prior to medical evacuation. This novel military partnership ultimately allowed the neurosurgeon to focus on the tenets of the craft and thereby the dynamic needs of the patient first and foremost. Since the success of these missions, the NeuroTeam has evolved into a detachable unit, the "Head and Neck Team," comprising neurosurgeons, otolaryngologists, and ophthalmologists, supported by a postinjury hospital unit, which includes an embedded neurocritical care physician. The creation and evolution of the NeuroTeam, necessitated by a shortage of military neurosurgeons and the dangerous shift in military wartime tactics, best exemplifies multidisciplinary collaboration and military medicine agility. As neurocritical care continues to evolve into a highly complex, distinct specialty, the lessons learned by the NeuroTeam ultimately serve as a reminder for civilian and military physicians alike. Despite the conditions and despite one's professional ego, patients with highly complex morbid neurological disease deserve expert, multidisciplinary management for survival.

Background: During the last 20 years of conflict in the Middle East, improvements in body armor and the use of improvised explosive devices have resulted in an increased incidence of complex craniofacial trauma (CFT). Currently, CFT comprises up to 40% of all casualties. We present new data from the recent conflict in Iraq and Syria during Operation Inherent Resolve., Methods: Data were collected for patients treated at role 1, role 2, and role 3 facilities in Iraq and Syria over a 1-year period. During this time, a specialized head & neck surgical augmentation team was deployed and colocated with the central role 3 facility. Data included for this cross-sectional study are as follows: injury type and mechanism, triage category, initial managing facility and subsequent levels of care, and procedures performed., Results: Ninety-six patients sustained CFT over the study period. The most common injuries were soft tissue (57%), followed by cranial (44%) and orbital/facial (31%). Associated truncal and/or extremity injuries were seen in 46 patients (48%). There were marked differences in incidence and pattern of injuries between mechanisms (all p < 0.05). While improvised explosive devices had the highest rate of cranial and truncal injuries, gunshot wounds and blunt mechanisms had higher incidences of orbital/facial and neck injuries. Overall, 45% required operative interventions including complex facial reconstruction, craniotomy, and open globe repair. Mortality was 6% with 83% due to associated severe brain injury. Most patients were local nationals (70%) who required discharge or transfer to the local health care system., Conclusion: Complex craniofacial trauma is increasingly seen by deployed surgeons, regardless of subspecialty training or location. Deployment of a centrally located head and neck team greatly enhances the capabilities for forward deployed management of CFT, with excellent outcomes for both US and local national patients., Level of Evidence: Therapeutic/care management; Level V., (Copyright © 2022 Written work prepared by employees of the Federal Government as part of their official duties is, under the U.S. Copyright Act, a “work of the United States Government” for which copyright protection under Title 17 of the United States Code is not available.

Background: Improvised explosive devices have resulted in a unique polytrauma injury pattern termed dismounted complex blast injury (DCBI), which is frequent in the modern military theater. Dismounted complex blast injury is characterized by extremity amputations, junctional vascular injury, and blast traumatic brain injury (bTBI). We developed a combat casualty relevant DCBI swine model, which combines hemorrhagic shock (HS) and tissue injury (TI) with a bTBI, to study interventions in this unique and devastating military injury pattern., Methods: A 50-kg male Yorkshire swine were randomized to the DCBI or SHAM group (instrumentation only). Those in the DCBI group were subjected to HS, TI, and bTBI. The blast injury was applied using a 55-psi shock tube wave. Tissue injury was created with bilateral open femur fractures. Hemorrhagic shock was induced by bleeding from femoral arteries to target pressure. A resuscitation protocol modified from the Tactical Combat Casualty Care guidelines simulated battlefield resuscitation for 240 minutes., Results: Eight swine underwent the DCBI model and five were allocated to the SHAM group. In the DCBI model the mean base excess achieved at the end of the HS shock was -8.57 ± 5.13 mmol·L -1 . A significant coagulopathy was detected in the DCBI model as measured by prothrombin time (15.8 seconds DCBI vs. 12.86 seconds SHAM; p = 0.02) and thromboelastography maximum amplitude (68.5 mm DCBI vs. 78.3 mm in SHAM; p = 0.0003). For the DCBI models, intracranial pressure (ICP) increased by a mean of 13 mm Hg, reaching a final ICP of 24 ± 7.7 mm Hg., Conclusion: We created a reproducible large animal model to study the combined effects of severe HS, TI, and bTBI on coagulation and ICP in the setting of DCBI, with significant translational applications for the care of military warfighters. Within the 4-hour observational period, the swine developed a consistent coagulopathy with a concurrent brain injury evidenced by increasing ICP., (Copyright © 2022 Wolters Kluwer Health, Inc.

Background: Firework-related ocular injuries (FWROI) are a major cause of preventable visual impairment. This study aimed to analyze the occurrence and outcome of FWROI in Switzerland., Methods: This retrospective multicenter study included patients with FWROI from seven centers in Switzerland from January 2009 to August 2020. Demographic information, type of injuries, medical and surgical treatments, the best corrected visual acuity (BCVA) at baseline and end of follow-up, occurrence and type of secondary complications, and duration of hospitalization were analyzed., Results: A total of 105 patients (119 eyes) with a mean age of 27.1 ± 15.9 years were included in the study (71.4% male patients; 29.5% underage). Most injuries occurred around New Year's Eve (32.4%) and the Swiss national holiday on 1 August (60.9%). The most common anterior segment findings were conjunctival or corneal foreign bodies (58%), whereas Berlin's edema was the most common posterior segment finding (11.4%). Globe ruptures were found in four patients. The mean BCVA in all patients at first presentation was 0.4 ± 0.8 logMAR and improved to 0.3 ± 0.8 logMAR at last follow-up. A primary surgical intervention was performed in 48 eyes (40.3%). Hospitalization directly after the trauma was necessary for 18 patients for a mean of 5.8 ± 4.1 days, and a total of 4.9 ± 7.6 follow-up visits were needed., Conclusion: This study provides the first data on FWROI in Switzerland, which are helpful for further preventive and educational programs and comparisons with other countries., (© 2022.

Background: Civilian blast injuries are common during celebrations and festivities. In the intervening times, civilian nonterrorist blast events are rare. The aim of this report is to highlight the increasing occurrence of blast injuries to the dominant right hand of hunters and the ensuing crippling consequences., Methodology: A review of incidental blast injuries to the hand among hunters was conducted. The case files, clinical photographs, and radiographs of consecutive cases of blast injuries presenting to our unit over 3½ years were studied., Result: Six patients had incidental blast injuries to the hand within the period. All the patients were males and hunters by profession. The age range was 30-49 years. The dominant right hand was involved in all the six cases with high-energy soft tissue and bony injuries. Five patients had staged soft tissue coverage while the sixth patient, after initial resuscitation, discharged against medical advice due to economic constraints. Multiple joint stiffness and significant disability occurred in all the affected hands. None of the patients represented for secondary procedures., Conclusion: Incidental blast injuries to the hands of local hunters are lifestyle threatening. The dominant right hand is invariably involved with attendant crippling socioeconomic consequences. Meticulous clinical care and methodical operative intervention are primal to hand salvage., Competing Interests: None

A dramatic increase in firework-related blast injuries to the hand and upper extremity resulted in record-setting numbers at our institution over the July 4, 2018, holiday. This led our hand and upper extremity department to create a public service announcement (PSA) campaign regarding firework safety and injury prevention. This PSA was broadcast in advance of the next July 4 holiday via several media platforms including television, radio, and the internet. The following year only 4 patients required surgery for firework-related blast injuries to the hand and upper extremity over the same 10-day period, including the weekends before and after the July 4, 2019, holiday. This represented a considerable reduction compared with the 14 patients seen within the same time frame in 2018. The purpose of this article was to outline the process and report the impact of creating and disseminating a public service announcement for firework-related blast injury prevention., (Copyright © 2022 American Society for Surgery of the Hand.

Background: The long-term consequences of musculoskeletal trauma can be profound and can extend beyond the post-injury period. The surveillance of long-term expenditures among individuals who sustain orthopaedic trauma has been limited in prior work. We sought to compare the health-care requirements of active-duty individuals who sustained orthopaedic injuries in combat and non-combat (United States) environments using TRICARE claims data., Methods: We identified service members who sustained combat or non-combat musculoskeletal injuries between 2007 and 2011. Combat-injured personnel were matched to those in the non-combat-injured cohort on a 1:1 basis using biologic sex, year of the injury, Injury Severity Score (ISS), and age at the index hospitalization. Health-care utilization was surveyed through 2018. The total health-care expenditures over the post-injury period were the primary outcome. These were assessed as a total overall cost and then as costs adjusted per year of follow-up. We used negative binomial regression to identify the independent association between risk factors and health-care expenditures., Results: We identified 2,119 individuals who sustained combat-related orthopaedic trauma and 2,119 individuals who sustained non-combat injuries. The most common mechanism of injury within the combat-injured cohort was blast-related trauma (59%), and 418 individuals (20%) sustained an amputation. The total costs were $156,886 for the combat-injured group compared with $55,873 for the non-combat-injured group (p < 0.001). Combat-related orthopaedic injuries were associated with a 43% increase in health-care expenditures (incidence rate ratio, 1.43 [95% confidence interval, 1.19 to 1.73]). Severe ISS at presentation, ≥2 comorbidities, and amputations were also significantly associated with health-care utilization, as was junior enlisted rank, our proxy for socioeconomic status., Conclusions: Health-care requirements and associated costs are substantial among service members sustaining combat and non-combat orthopaedic trauma. Given the sociodemographic characteristics of our cohort, we believe that these results are translatable to civilians who sustain similar types of musculoskeletal trauma., Competing Interests: Disclosure: The Disclosure of Potential Conflicts of Interest forms are provided with the online version of the article (http://links.lww.com/JBJS/G926)., (Copyright © 2022 by The Journal of Bone and Joint Surgery, Incorporated.)

Explosions can cause severe injuries, which affect multiple organ systems and leave extensive soft tissue defects. In unstable patients, damage control surgery initially focuses exclusively on controlling bleeding and contamination with the aim of preserving life and limbs. The excision of all necrotic tissue, extensive wound irrigation with antiseptic solutions and a calculated antibiotic prophylaxis, which is subsequently adapted to the microbiological findings, are the basis for sufficient infection control. As the tissue damage caused by the pressure surge can regenerate over time as well as become secondarily necrotic (developing wounds), several revision operations are often necessary to assess the viability of tissue in the sense of serial debridement. In the case of extensive soft tissue injuries temporary vacuum-assisted closure (VAC) techniques can bridge the time to the earliest possible definitive plastic surgical wound closure; however, this must not delay the closure of the defect., (© 2022.

After explosions, various injury mechanisms lead to multiple injuries that can affect the entire body. While high pressure peaks and exposure to heat, especially in the vicinity of a detonation, can cause severe injuries and organ damage, fragments also pose a considerable threat to explosion victims even over long distances. The recognition and treatment of life-threatening disorders and the assessment of the severity of the injury are just as challenging for the entire treatment team as long-term operative management, reconstruction strategies and rehabilitation of the complex injuries. Knowledge of the injury mechanics and the pathophysiology of blast injuries should help the interdisciplinary team to master this challenge., (© 2021.

Objective: To study the incidence and structure of combat gunshot surgical trauma received during the 2 nd Karabakh War and to analyze the results of treatment of these victims., Material and Methods: We analyzed surgical treatment of 60 victims with combat gunshot surgical trauma received during the 2 nd Karabakh war. In 25 (41.7%) victims, injury occurred as a result of mine-explosive trauma. These victims were divided into 3 groups depending on mechanism of mine-explosive injury. The 1 st group included 7 (28%) patients who received mine-explosive injury due to indirect (propelling) effect of blast wave. The 2 nd group included 14 (56%) victims in whom mine-explosive injury was caused by non-contact (distant) impact of mine fragments. The 3 rd group consisted of 4 (16%) patients whose mine-explosive injuries were caused by direct impact of explosion factors on various anatomical areas. Patients were also ranked into 3 groups depending on the nature and severity of mine-explosive injury: wounded with isolated injuries ( n =16, 64%), wounded with concomitant injuries ( n =2.8%), wounded with combined and multiple injuries ( n =7, 28%)., Results: Most patients underwent organ-sparing procedures. Resections were performed only in 4 cases (splenectomy - 3, nephrectomy - 1). Postoperative complications developed in 23 (38.3%) wounded (suppuration of postoperative wounds - 13, post-traumatic pleuritis - 5, clotted hemothorax - 2, subphrenic abscess - 1, phlegmon of perineum and perianal region - 2). Mortality rate was 1.7%., Conclusion: Timely sorting and evacuation of victims, early qualified surgical care and correct postoperative management with monitoring of vital functions can improve the results of treatment of victims with mine-explosive trauma. Autologous skin grafting for extensive defects and closure of colostomy with restoration of colon continuity were essential in rehabilitation of these patients.

Background/purpose: To characterize the nature of posterior segment ocular injuries in combat trauma., Methods: Eyes in the Walter Reed Ocular Trauma Database were evaluated for the presence of posterior segment injury. Final visual outcomes in open-globe versus closed-globe injuries and by zone of injury and the types of posterior segment injuries in open-globe versus closed-globe injuries were assessed., Results: Four hundred fifty-two of 890 eyes (50.8%) had at least one posterior segment injury. The mechanism of injury was most commonly an improvised explosive device in 280 (62.0%) eyes. Sixty-one patients (13.5%) had a Zone I injury, 50 (11.1%) a Zone II injury, and 341 (75.4%) a Zone III injury. Patients with Zone I injuries were more likely to have a final visual acuity of 20/200 or better compared with patients with either a Zone II (P < 0.001) or Zone III injury (P = 0.007). Eyes with a closed-globe injury were more likely to have a final visual acuity of 20/200 or better compared with those with an open-globe injury (P < 0.001). Furthermore, closed-globe injury compared with open-globe injury had a lower risk of vitreous hemorrhage (odds ratio 0.32, P < 0.001), proliferative vitreoretinopathy (odds ratio 0.14, P < 0.001), and retinal detachment (odds ratio 0.18, P < 0.001) but a higher risk of chorioretinal rupture (odds ratio 2.82, P < 0.001) and macular hole (odds ratio 3.46, P = 0.004)., Conclusion: Patients with combat ophthalmic trauma had similar posterior segment injury patterns to civilian trauma in open-globe versus closed-globe injuries. Zone II and III injuries were associated with a worse visual prognosis.

Iliopsoas abscesses (IPA) are uncommon, with an associated mortality rate of up to 20%. We describe the case of a 55-year-old man war veteran who presented with an unusual cause of IPA secondary to retained foreign body (FB). His initial trauma 30 years before was a result of a blast injury with shrapnel penetration suffered after inadvertently driving over a landmine as an ambulance driver in a conflict region. A CT scan was performed, revealing a 13 mmx8 mm radio-opaque FB within the right psoas at the level of the fifth lumbar vertebra with a surrounding collection. Subsequent open surgical exploration removed two gravel fragments. Given the knowledge of a traumatic blast injury with retained FB and repeated episodes of sepsis, surgical exploration is warranted. To our knowledge, this is the first case of recurrent IPA secondary to a retained FB from a historical trauma., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2021.

Background: Flap-based limb salvage surgery balances the morbidity and complexity of soft tissue transfer against the potential benefit of preserving a functional limb when faced with a traumatized extremity with composite tissue injury. These composite tissue injuries are well suited for multidisciplinary management between orthopaedic and plastic surgeons. Thus, it makes intuitive sense that a collaborative, orthoplastic approach to flap-based limb salvage surgery can result in improved outcomes with decreased risk of flap failure and other complications, raising the question of whether this orthoplastic team approach should be the new standard of care in limb salvage surgery., Questions/purposes: (1) Is there an association between increased annual institutional volume and perioperative complications to include free and local flap failure (substantial flap viability loss necessitating return to the operating room for debridement of a major portion or all of the flap or amputation)? (2) Is an integrated orthoplastic collaborative approach to managing combat-related traumatic injuries of the extremities individually associated with a decreased risk of flap failure and overall flap-related complications? (3) What other factors, such as location of injury, injury severity score, and initial inpatient length of stay, were associated with flap necrosis and flap-related complications?, Methods: We performed a retrospective review of the electronic medical records of all patients who underwent flap-based limb salvage for combat-related extremity trauma in the United States Military Health System's National Capital Region between January 1, 2003 and December 31, 2012. In total, 307 patients underwent 330 flap procedures. Of the 330 flaps, 59% (195) were local or pedicled flaps and 41% (135) were free flaps. Patients were primarily male (99% [303]), with a median (interquartile range) age of 24 years old (IQR 21 to 29), and 87% (267 of 307) of injuries were sustained from a blast mechanism. We collected data on patient demographics, annual case volume involving flap coverage of extremities, mechanism of injury, flap characteristics, perioperative complications, flap failure, flap revision, isolated orthopaedic management versus an integrated orthoplastic approach, and other salvage procedures. For the purposes of this study, orthoplastic management refers to operative management of flap coverage with microvascular surgeons present for soft tissue transfer after initial debridement and fixation by orthopaedic surgery. The orthoplastic management was implemented on a case-by-case basis based on individual injury characteristics and the surgeon's discretion with no formal starting point. When implemented, the orthoplastic team consisted of an orthopaedic surgeon and microvascular-trained hand surgeons and/or plastic surgeons. In all, 77% (254 of 330) of flaps were performed using this model. We considered perioperative flap complications as any complication (such as infection, hematoma, dehiscence, congestion, or necrosis) resulting in return to the operating room for re-evaluation, correction, or partial debridement of the flap. We defined flap failure as a return to the operating room for debridement of a major portion of the flap or amputation secondary to complete or near-complete loss of flap viability. Of the flap procedures, 12% (40 of 330) were classified as a failure and 14% (46 of 330) experienced complications necessitating return to the operating room. Over the study period, free flaps were not more likely to fail than pedicled flaps (11% versus 13%; p = 0.52) or have complications necessitating additional procedures (14% versus 16%; p = 0.65)., Results: Our multiple linear regression model demonstrated that an increased number of free flaps performed in our institution annually in any given year was associated with a lower likelihood of failure per case (r = -0.17; p = 0.03) and lower likelihood of reoperation for each flap (r = -0.34; p < 0.001), after adjusting for injury severity and team type (orthoplastic or orthopaedic only). We observed a similar relationship for pedicled flaps, with increased annual case volume associated with a decreased risk of flap failure and reoperation per case after adjusting for injury severity and team type (r = -0.21; p = 0.003 and r = -0.22; p < 0.001, respectively). Employment of a collaborative orthoplastic team approach was associated with decreased flap failures (odds ratio 0.4 [95% confidence interval 0.2 to 0.9]; p = 0.02). Factors associated with flap failure included a lower extremity flap (OR 2.7 [95% CI 1.3 to 6.2]; p = 0.01) and use of muscle flaps (OR 2.3 [95% CI 1.1 to 5.3]; p = 0.02)., Conclusion: Although prior reports of combat-related extremity trauma have described greater salvage success with the use of pedicled flaps, these reports are biased by institutional inexperience with free tissue transfer, the lack of a coordinated multiservice effort, and severity of injury bias (the most severe injuries often result in free tissue transfer). Our institutional experience, alongside a growing body of literature regarding complex extremity trauma in the civilian setting, suggest a benefit to free tissue coverage to treat complex extremity trauma with adequate practice volume and collaboration. We demonstrated that flap failure and flap-related complications are inversely associated with institutional experience regardless of flap type. Additionally, a collaborative orthoplastic approach was associated with decreased flap failures. However, these results must be interpreted with consideration for potential confounding between the increased case volume coinciding with more frequent collaboration between orthopaedic and plastic surgeons. Given these findings, consideration of an orthoplastic approach at high-volume institutions to address soft tissue coverage in complex extremity trauma may lead to decreased flap failure rates., Level of Evidence: Level III, therapeutic study., Competing Interests: Each author certifies that there are no funding or commercial associations (consultancies, stock ownership, equity interest, patent/licensing arrangements, etc.) that might pose a conflict of interest in connection with the submitted article related to the author or any immediate family members.

Background: Selecting the best treatment for patients with severe terminal lower-limb injury remains a challenge. For some injuries, amputation may result in better outcomes than limb salvage. This study compared the outcomes of patients who underwent limb salvage with those that would have been achieved had they undergone amputation., Methods: This multicenter prospective observational study included patients 18 to 60 years of age in whom a Type-III pilon or IIIB or C ankle fracture, a Type-III talar or calcaneal fracture, or an open or closed blast/crush foot injury had been treated with limb salvage (n = 488) or amputation (n = 151) and followed for 18 months. The primary outcome was the Short Musculoskeletal Function Assessment (SMFA). Causal effect estimates of the improvement that amputation would have provided if it had been performed instead of limb salvage were calculated for the SMFA score, physical performance, pain, participation in vigorous activities, and return to work., Results: The patients who underwent limb salvage would have had small differences in most outcomes had they undergone amputation. The most notable difference was an improvement in the SMFA mobility score of 7 points (95% confidence interval [CI] = 2.0 to 10.7). Improvements were largest for pilon/ankle fractures and complex injury patterns., Conclusions: Amputation should be considered a treatment option rather than a last resort for the most complex terminal lower-limb injuries., Level of Evidence: Therapeutic Level II.

Importance: A review of the injury patterns, treatment strategies, and responding physicians' experience during the Port of Beirut blast may help guide future ophthalmic disaster response plans., Objective: To present the ophthalmic injuries and difficulties encountered as a result of the Port of Beirut blast on August 4, 2020., Design, Setting, and Participants: A retrospective medical record review of all patients who presented to the emergency department and 13 ophthalmology outpatient clinics at the American University of Beirut Medical Center for treatment of ophthalmic injuries sustained from the explosion in Port of Beirut, Beirut, Lebanon, from August 4 to the end of November 2020. Patients were identified from emergency records, outpatient records, and operative reports., Main Outcomes and Measures: Types of ocular injuries, final best-corrected visual acuity, and need for surgical intervention were evaluated. Visual acuity was measured with correction based on noncycloplegic refraction using the Snellen medical record., Exposures: Ocular or ocular adnexal injuries sustained from the Port of Beirut explosion., Results: A total of 39 blast survivors with ocular injuries were included in this study. Twenty-two patients presented with ocular injuries on the day of the blast, and 17 patients presented within the following 3 months to the ophthalmology clinics for a total of 48 eyes of 39 patients were treated secondary to the blast. Thirty-five patients (89.6%) were adults, and 24 (61.5%) were female. A total of 21 patients (53.8%) required surgical intervention, more than half of which were urgently requested on the same day of presentation (14 [35.9%]). Most eye injuries were caused by debris and shrapnel from shattered glass leading to surface injury (26 [54.2%]), eyelid lacerations (20 [41.6%]), orbital fractures (14 [29.2%]), brow lacerations (10 [20.8%]), hyphema (9 [18.8%]), open globe injuries (10 [20.8%]), and other global injuries. Only 7 injured eyes (14.5%) had a final best-corrected visual acuity of less than 20/200, including all 4 open globe injuries with primary no light perception (8.3%) requiring enucleation or evisceration., Conclusions and Relevance: In the aftermath of the Port of Beirut explosion, a review of the ophthalmic injuries showed a predominance of shrapnel-based injuries, many of which had a delayed presentation owing to the strain placed on health care services. Reverting to basic approaches was necessary in the context of a malfunctioning electronic medical record system.

Background: War injuries differ from other injuries owing to the large tissue defects they cause and their high risk of contamination. As fragments scattered by high-energy firearms and explosives cause serious composite tissue damage, repair of such injuries is difficult and requires a long treatment period. We discuss the treatment methods used for injured Syrian War refugees admitted to our clinic and present the most effective repair methods for war-related tissue defects for each region of the body., Methods: A total of 61 patients treated between June 2012 and April 2015 were retrospectively evaluated in terms of age, gender, duration of hospitalisation, injury site and repair method employed. The patients were grouped by region injured (head/neck, extremities and trunk)., Results: The female-to-male ratio of the patients was 16/45, and their mean age was 25.2 (range, 3-51) years. Twenty-two patients were under the age of 18. The mean duration of hospitalisation was 28.5 days. A total of 130 operations were performed on the patients, including debridement and revisions. Repairs were conducted with free flaps in 17 patients (6 on the head/neck region, 11 on extremities) and with pedicle flaps in 28 patients (11 on the head/neck region, 12 on extremities, 5 on the trunk). Two patients experienced flap loss without other complications, and other patients experienced complications including bleeding, infection, flap detachment, hematoma and seroma., Conclusions: War injuries cause tissue damage of a composite and extensive nature. Most affect the extremities, followed by the head/neck and trunk regions. They are primarily sustained by the young population, not usually easy to treat, and require long hospitalisation periods. A variety of methods may be preferred to treat these injuries., (© 2021 John Wiley & Sons Ltd.)

Background: The collapse of the Syrian healthcare system during the civil war led numerous citizens to cross the Syrian-Israeli border to seek medical care., Objectives: To describe the epidemiology of peripheral nerve injuries (PNIs) sustained in war, their management, and short-term outcomes., Methods: A retrospective case series study was conducted on 45 consecutive patients aged 25.7 ± 9.3 years. These patients were referred to the hand surgery unit of the department of orthopedic surgery and traumatology at Galilee Medical Center between December 2014 and June 2018. Median time between injury and presentation was 60 days. Injury pattern, additional injuries, surgical findings and management, complications, and length of hospital stay were extracted from medical records., Results: Most injuries were blast (55.6%) followed by gunshot injuries (37.8%). There were 9 brachial plexus injuries, 9 sciatic nerve injuries, and 38 PNIs distal to the plexus: specifically 20 ulnar, 11 median, and 7 radial nerve injuries. In the latter group, neurotmesis or axonotmesis was found in 29 nerves. Coaptation was possible in 21 nerves necessitating cable grafting in 19. A tendon transfer was performed for 13 peripheral nerves, occasionally supplementing the nerve repair. The patients returned to their country after discharge, average follow-up was 53.6 ± 49.6 days., Conclusions: For nerve injuries sustained in war, early surgical treatment and providing adequate soft tissue conditions is recommended. Tendon transfers are useful to regain early function.

Terrorist attacks have become more acute, less predictable and frequently involve use of explosives and gunfire to inflict mass casualty to civilians. Resource demand has been reported in Role 3 Medical Facilities but the continued resource required to manage blast and ballistic injuries has not been quantified. This study aimed to assess the resource required for blast and ballistic injuries at the United Kingdom's Role 4 Medical Facility. Military patients admitted to the Queen Elizabeth Hospital (Role 4 Medical Facility) from Afghanistan with blast or ballistic injuries during the 2012 calendar year were retrospectively reviewed. Injury pattern, theatre resource, length of stay and cost analysis were performed. This study included 99 blast and 53 gunshot wound (GSW) patients. Blast patients were more likely to suffer polytrauma than GSW (53% vs 23%), underwent more surgical procedures and utilized double the theatre time. Blast injury patients had a longer length of stay in hospital. The average cost per patient for blast patients was double that of the GSW injury cohort. The Queen Elizabeth experience represents a continuous flow of severely injured military casualties whilst managing concurrent civilian trauma over a long period. This workload has encouraged systematic advancements in managing high numbers of injured patients from point of wounding to rehabilitation. Distribution of resource, theatre planning and multi-disciplinary team working are critical in effectively managing Major Incidents such as terror attacks. Drawing on previous Role 4 Medical Facility experience can aid UK hospitals in terms of strategy and resource distribution., Competing Interests: Declaration of Competing Interest None to declare., (Copyright © 2021.

Evolution in extremity injury treatment often occurs during major conflicts, with lessons learned applied and translated among military and civilian settings. In recent periods of war, improvements in protective equipment, in-theater damage control resuscitation/surgery, delivery of antibiotics locally/systemically, and rapid evacuation to higher levels of medical care capabilities have greatly improved combat casualty survivability rates. Additionally, widespread application of lower extremity tourniquets also has prevented casualties from exsanguination, thus reducing hemorrhagic-related deaths. Secondary to these, a high number of combat casualties suffering lower extremity traumatic injuries have presented for functional limb reconstruction and restoration as well as residual limb care., Competing Interests: Disclosure Dr I.

Purpose: The chosen treatment and long-term evaluation of hindfoot blast injuries are not well-represented in the literature. The first objective of this retrospective study was to evaluate functional outcomes in French service personnel who had sustained such injuries caused by improvised explosive devices. The second objective was to compare the results for patients who had amputations with those who did not. The hypothesis was that amputee recovered better function., Methods: Long-term functional evaluations were carried out using the American Orthopaedic Foot and Ankle Society scale (AOFAS), the Foot and Ankle Ability Measure (FAAM), and the Short Form 12 health survey (SF-12)., Results: Eight servicemen with ten hindfoot blast injuries were reviewed at a mean follow-up time of seven years. Primary management was always conservative although half of the patients required late amputation for chronic pain. The patients who underwent amputation reported significantly lower levels of pain than those who did not have an amputation, with higher FAAM and SF-12 scores., Conclusion: In this series, long-term functional results appear better in the amputated group.

Introduction: Specialist units that assist indigenous forces (IF) in their strategic aims are supported by medical teams providing point of injury emergency care for casualties, including IF and civilians (Civ). We investigated the activities of a Coalition Forces far-forward medical facility, in order to inform medical providers about the facilities and resources required for medical support to IF and Civ during such operations., Methods: A prospective observational study (June to August 2017) undertaken at a far-forward Coalition Forces medical support unit (12 rotating personnel) recorded patient details (IF or Civ), mechanism of injury (MOI), number of blood products used, damage control resuscitation (DCR) and damage control surgery (DCS), number of mass casualty (MASCAL) scenarios, resuscitative thoracotomy, resuscitative endovascular balloon occlusion of the aorta (REBOA) and whole blood emergency donor panels (EDP)., Results: 680 casualties included 478 IF and 202 Civ (45.5% of the Civ were paediatric). Most common MOIs were blast (n=425; 62.5%) and gunshot wound (n=200; 29.4%). Fifteen (2.2%) casualties died; 627 (92.2%) were transferred to local hospitals. DCR was used for 203 (29.9%), and DCS for 182 (26.8%) casualties. There were 23 MASCAL scenarios, 1220 transfusions and 32 EDPs. REBOA was performed eight times, and thoracotomy was performed 27 times., Conclusions: A small medical team provided high-tempo emergency resuscitative care for hundreds of IF and Civ casualties within a short space of time using state-of-the-art resuscitative modalities. DCR and DCS were undertaken with a large number of EDPs, and a high survival-to-transfer rate., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Background: Modern conflicts take a disproportionate and increasing toll on civilians and children. Since 2013, hundreds of Syrian children have fled to the Israeli border. Severely injured children were triaged for military airborne transport and brought to civilian trauma centers in Israel. After recovery, these patients returned to their homes in Syria.We sought to describe a unique model of a coordinated military-civilian response for the stabilization, transport, and in-hospital management of severe pediatric warzone trauma., Methods: Prehospital and in-hospital data of all severe pediatric trauma casualties transported by military helicopters from the Syrian border were extracted. Data were abstracted from the electronic medical records of military and civilian medical centers' trauma registries., Results: Sixteen critically injured children with a median age of 9.5 years (interquartile range [IQR], 6.5-11.5) were transported from the Syrian border to Level I and Level II trauma centers within Israel. All patients were admitted to intensive care units. Eight patients underwent lifesaving procedures during flight, 7 required airway management, and 5 required thoracostomy. The median injury severity score was 35 (IQR, 13-49). Seven laparotomies, 5 craniotomies, 3 orthopedic surgeries, and 1 skin graft surgery were performed. The median intensive care unit and hospital length of stay were 6 days (IQR, 3-16) and 34 days (IQR, 14-46), respectively. Fifteen patients survived to hospital discharge and returned to their families., Conclusion: The findings of this small cohort suggest the benefits of a coordinated military-civilian retrieval of severe pediatric warzone trauma., Level of Evidence: Therapeutic, Level V., (Copyright © 2020 Wolters Kluwer Health, Inc.

The authors describe successful treatment of a patient with consequences of a mine-explosive wound of the right thigh and abdomen, including damage to the duodenum. Staged surgical treatment made it possible to identify and eliminate defects in primary surgical treatment in time. Thus, favorable treatment results were obtained.

November 2018 saw the deployment of a medical team with a remit to provide far forward medical support to UK, Coalition and indigenous forces. The delivery of this capability demanded a solution unique within the UK Defence Medical Services. The 'light role' casualty collection points provided emergency medical care to 475 casualties over a 4-month period. The success of the deployment was dependant on the ability to remain light and agile which brought with it logistical considerations. The clinical caseload was predominantly secondary blast injury and gunshot wound (GSW). The positioning of a Role 1 facility close to the front line of troops enabled early Damage Control Resuscitation including the delivery of blood products. MEDEVAC to Role 2 was enabled by indigenous forces. The unique situation demanded bespoke solutions for documentation and blood warming. The lessons learnt during the deployment may form a blueprint for future contingency operations., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Background: Firework injuries to the hand can be devastating due to the explosive and ballistic nature of these devices. The aim of this study was to describe the injury and treatment characteristics of patients requiring surgery for firework-related hand injuries and to investigate which factors are associated with an increased utilization of health care resources. Methods: A retrospective chart review of patients undergoing surgery for firework-related hand injuries at two American College of Surgeons level I trauma centers between 2005 and 2016 was performed. Twenty cases were identified. These patients were evaluated for demographics, injury characteristics, number and types of surgical interventions, length of stay, and utilization of health care resources. Bivariate analyses were performed to investigate which factors were associated with increased consumption of health care resources. Results: Injuries ranged from digital nerve injuries to traumatic amputation. Patients underwent a median of 3 surgical operations. More than half the patients underwent flap or skin graft coverage of a soft tissue defect. The median length of hospital stay was 7 days. Factors found to be associated with an increased utilization of surgical and hospital resources included a first web space injury, thumb fracture, and traumatic amputation of any digit. Conclusions: The morbidity inflicted by firework injuries to individual patients is substantial. Patients with severe injuries undergo a median of three surgical operations and have a long duration of initial hospital stay. Knowing which factors are associated with an increased utilization of resources can help prognosticate these preventable injuries.

"Blast hand" is a traumatic hand injury related to an explosion. Artisanal gold miners use dynamite to excavate gold pits; such activities expose them to blast hand injuries. This work aims to study blast injuries to gold miners' hands. A 25-month retrospective study was performed. Data on the traumatic event, patients, and injuries were collected and analyzed. Dedicated classifications and scores were used to evaluate the injury topography, injury severity, physical dependence, and aesthetic impact. Data were analyzed statistically. Thirty patients with 46 blast hand injuries among 516 hand injuries were collected. All patients were males and full-time artisanal gold miners. They were seen in the emergency room an average of 10.2hours (1-72) after the explosion. Explosions were caused by a 500g dynamite charge in all cases. The detonation was mainly thermal (n=13), triggered by the patient himself (n=24) and inside the gold pit (n=20). Injuries were bilateral (53%) or left side predominant (59%). Complex injuries were present in 21 hands. The MHISS (Modified Hand Injury Severity Score) was severe (n=7) and major (n=32). Associated injuries were musculoskeletal (n=12), ophthalmologic (n=14) and maxillofacial (n=10). Complexes injuries were correlated to being inside the pit at the time of the explosion. Treatment was conservative more often (n=33) than amputation (n=13). The functional recovery was complete in 22 hands (10 patients). Return to work at the same level was possible for only eight hands (5 patients). The presence of local sequelae or associated injuries negatively impacted the return to work. In Burkina Faso, gold miner's blast hand injuries cause post-traumatic social and professional reintegration issues. Better regulation of artisanal gold mining and expansion of treatment modalities (microsurgery, hand rehabilitation, splinting) may improve the outcome., (Copyright © 2020 SFCM.

The present case report describes a pediatric patient that sustained and survived major abdominal trauma due to an open-air explosion during the Syrian civil war. A 9-year-old male patient was brought to our hospital's paediatric emergency department after a bomb explosion that occurred 8 hours prior to presentation. The patient had a severe flap-like skin defect that extended from the below the umbilicus to the right femur. The defect was embedded with multiple stones, plastic, and soil fragments of varying size. Debridement of the anterior abdominal wall was performed, followed by exploratory laparotomy. Multiple sites of perforation of the small bowel were resected, and anastomosis was performed. Vacuum-assisted closure (VAC) was applied to the large wound area. The VAC dressing was changed every 3 days. Granulation tissue developed post-operatively after 26 days and the defect was repaired using skin grafts harvested from the patient's left leg. The patient was considered fully recovered and was discharged 34 days post-surgery. The presented case shows that despite the severity of the patient's major abdominal injuries, rapid wound debridement, exploratory laparotomy, VAC therapy and a multidisciplinary approach are crucial in preventing death and achieving a full recovery., (Celsius.)

Terrorism-related incidents and shootings that involve the use of war weapons and explosives are associated with gunshot and blast injuries. Despite the perceived threat of terrorism, these incidents and injuries are rare in Germany. For this reason, healthcare providers are unlikely to have a full understanding of the special aspects of managing these types of injuries. Until a clear and complete picture of the situation is available after a terrorist or shooter incident, tactical and strategic approaches to the clinical management of the injured must be tailored to circumstances that have the potential to overwhelm resources temporarily. Hospitals providing initial care must be aware that the first patients who are taken to medical facilities will present with uncontrollable bleeding from injuries to the trunk and body cavities. To improve the outcome of these patients in extremis, the aim of the index surgery is to stop the bleeding and control the contamination. Unlike damage control surgery, which is tailored to the patient's condition, tactical abbreviated surgical care (TASC) is first and foremost adapted to the overall situation. Once the patients are stabilised and all information on the situation is available, the surgical management and reconstruction of gunshot and blast injuries can follow the principles of damage control (DC) and definitive early total care (ETC). The purpose of this article is to provide an overview of the pathophysiology of gunshot and blast injuries, wound ballistics, and the approach and procedures of successful surgical management.
