Periarticular blast wounds without fracture a prospective case series.

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.

A systematic review of otologic injuries sustained in civilian terrorist explosions.

PURPOSE: Determine the prevalence of otological symptoms and tympanic membrane perforation, healing rates of tympanic membrane perforation with surgical and conservative management, and hearing function in civilian victims of terrorist explosions. METHODS: A systematic review was conducted with searches on Medline, Embase, EMCare and CINAHL for publications between the 1st January 1945 and 26th May 2023. Studies with quantitative data addressing our aims were included. This review is registered with PROSPERO: CRD42020166768. Among 2611 studies screened, 18 studies comprising prospective and retrospective cohort studies were included. RESULTS: The percentage of eardrums perforated in patients admitted to hospital, under ENT follow up and attending the emergency department is 69.0% (CI 55.5-80.5%), 38.7% (CI 19.0-63.0%, I2 0.715%) and 21.0% (CI 11.9-34.3%, I2 0.718%) respectively. Perforated eardrums heal spontaneously in 62.9% (CI 50.4-73.8%, I2 0.687%) of cases and in 88.8% (CI 75.9-96.3%, I2 0.500%) of cases after surgery. Common symptoms present within one month of bombings are tinnitus 84.7% (CI 70.0-92.9%, I2 0.506%), hearing loss 83.0% (CI 64.5-92.9%, I2 0.505%) and ear fullness 59.7% (CI 13.4-93.4%, I2 0.719). Symptomatic status between one and six months commonly include no symptoms 57.5% (CI 46.0-68.3%), hearing loss 35.4% (CI 21.8-51.8%, I2 0.673%) and tinnitus 15.6% (CI 4.9-40.0%, I2 0.500%). Within one month of bombings, the most common hearing abnormality is sensorineural hearing loss affecting 26.9% (CI 16.9-40.1%, I2 0.689%) of ears 43.5% (CI 33.4-54.2%, I2 0.500) of people. CONCLUSION: Tympanic membrane perforation, subjective hearing loss, tinnitus, ear fullness and sensorineural hearing loss are common sequelae of civilian terrorist explosions.

Decreasing lower extremity junctional and perineal injury from explosive blast with a pelvic protection system.

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.

Some reflections on war for countries at peace: Would we know what to do?

In the west we have enjoyed peace for decades, but war is globally always present. Recent events have brought this into clear evidence. Once mass casualties occur, war enters civilian hospitals. As civilian Surgeons, used to our sophisticated elective work, would we know how to step up to the mark if required? Ballistic and blast wounds pose problems that need reflection before treatment starts. Delivery of early and complete debridement to high numbers of casualties, stabilising bone and closing the wounds becomes the role of the Ortho-plastic team. This article presents reflections from the senior author after ten years of working in zones of conflict. Import factors witnessed are how civilian surgeons are soon involved in unfamiliar work and must learn and adapt fast. Critical issues that arise are pressure of time, contamination, infection, and the need to never forget the importance of antibiotic stewardship even when under pressure. The advantage of supporting the Multidisciplinary team (MDT) approach, even as resources reduce, large numbers of casualties present, and staff are all under pressure, can bring order and efficiency to the chaos: It supplies best care to the victims within that current context and reduces unnecessary duplication of surgery and waste of manpower. The surgical management of ballistic and blast injuries could be added to the curriculum of young, civilian surgical trainees. This is preferable to having to acquire these skills during war with stress and minimal supervision. This would enhance the preparedness of counties at peace for disaster and conflict should the need arise. Well trained manpower could also support neighbouring countries who find themselves at war.

Challenges in the Head and Neck Department in the Diagnosis and Surgical Treatment of Patients Presenting to a Single Tertiary Hospital of Somalia With Extreme War Injuries.

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.

Lower Extremity Sandblast Injury: A Rarely Seen Injury Mechanism in the Civilian Population.

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.

Military experience in the management of pelvic fractures from OIF/OEF.

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.

Ocular Trauma and Traumatic Brain Injury on the Battlefield: A Systematic Review After 20 Years of Fighting the Global War on Terror.

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.

Beirut massive blast explosion: A unique injury pattern of the wounded population.

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.

[Treatment of victims with mine-explosive injuries]. / Rezul'taty lecheniya ranenykh s minno-vzryvnoi travmoi.

OBJECTIVE: To study the incidence and structure of combat gunshot surgical trauma received during the 2nd 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 2nd 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 1st group included 7 (28%) patients who received mine-explosive injury due to indirect (propelling) effect of blast wave. The 2nd group included 14 (56%) victims in whom mine-explosive injury was caused by non-contact (distant) impact of mine fragments. The 3rd 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.

Incidental blast injuries to the hands of hunters in suburban Africa.

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.

Operation "NeuroTeam": rendering the absolute best care for the most deserving patients under the most difficult conditions.

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.

Occurrence and outcome of firework-related ocular injuries in Switzerland: A descriptive retrospective study.

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.

A combat casualty relevant dismounted complex blast injury model in swine.

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.

The new face of war: Craniofacial injuries from Operation Inherent Resolve.

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.

Health-Care Utilization and Expenditures Associated with Long-Term Treatment After Combat and Non-Combat-Related Orthopaedic Trauma.

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.

[Blast injuries part 2 : Principles of medical treatment]. / Explosionstrauma Teil 2 : Medizinische Behandlungsprinzipien.

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.
