Abstract
INTRODUCTION Pelvis, lower limb and associated genital injury caused by explosive devices was responsible for mortality and considerable long-term morbidity for the UK Armed Forces during combat operations in Afghanistan, resulting in the issue of a pelvic protection system in 2010. The aim of this current research was to determine the medical coverage of the pelvis and thigh and to define the vertical dimensions of ballistic protective material for future pelvic protection (PP). METHOD CT scans from 120 male UK Armed Forces personnel were analysed to identify the anthropometric landmarks and vertical boundaries of coverage for the pelvis and thigh. Pelvic height was the vertical distance between the upper border of the iliac crest in the midaxillary plane to the most inferior point of the ischial tuberosity of the pelvis. Upper thigh height was proposed as a 100 mm fixed distance below the ischial tuberosities, enabling a tourniquet to be reproducibly applied. These distances were compared with the ballistic component of the five sizes of tier 1 PP using a paired t-test. RESULTS The vertical components of coverage measured using CT scans were all significantly less (p<0.01) compared with all five sizes of tier 1 PP; for example, the ballistic component of the smallest size of tier 1 PP measured 410 mm, which was larger than the 99th percentile male, which measured 346 mm on CT scans. CONCLUSIONS While all sizes of tier 1 PP provide coverage to the pelvis and upper thigh structures, there is an opportunity to optimise future PP. For example, comparing the large size of tier 1 PP to the 50th percentile male demonstrated an opportunity to reduce the ballistic protective component by 31%. Reducing the quantity of material used will improve heat dissipation and user comfort and reduce material mass and acquisition costs.

Abstract
Invasive fungal wound infections (IFIs) were an unexpected complication associated with blast-related wounds during Operation Enduring Freedom. Between 2010 and 2012, IFI incidence rates were as high as 10-12% for patients injured during Operation Enduring Freedom and admitted to the intensive care unit at the Landstuhl Regional Medical Center. Independent risk factors for the development of IFIs include dismounted blast injuries, above knee amputations and massive (>20 units) packed red blood cell transfusions within 24 hours after injury. The Joint Trauma System developed a Clinical Practice Guideline on IFI prevention, identification and management. Aggressive and frequent surgical debridement remains the primary therapy accompanied by topical antifungal therapy (e.g., Dakins solution). Empiric systemic antifungal therapy with both liposomal amphotericin B and an intravenous broad-spectrum triazole (e.g., voriconazole or posaconazole) should be administered when there is strong suspicion of IFI based on the occurrence of recurrent wound necrosis following serial surgical debridements, since many cases involve multiple fungal species. Other recommendations include: (1) early tissue sampling for wound histopathology and fungal cultures, (2) early consultation with infectious disease specialists, and (3) coordination with surgical pathology and clinical microbiology.

Abstract
Background We have previously reported a higher than expected rate of upper-extremity amputation (UEA) in victims of an antipersonnel improvised explosive device (AP-IED) compared with a similar cohort injured by antipersonnel mines (APM). The goal of this study was to describe the rate, severity and impact of UAE caused by an AP-IED. Methods We analyzed a prospective database of 100 consecutive dismounted AP-IED victims with pattern 1 injuries to compare the outcomes of the cohort with UEA to that without. Results We found that UEA (8 above elbow, 19 below elbow, 1 through elbow, 3 hand, 15 digit(s)) was much more prevalent with AP-IED than with APM (40% v. 6%, p < 0.001). In addition, UEA was associated with a higher rate of multiple amputations (39 [98%] v. 32 [53%], p < 0.001), bilateral lower-extremity amputation (LEA; 33 [82.5%] v. 30 [53.3%], p = 0.003) and facial injury (8 [20%] v. 4 [6.4%], p = 0.044), but not with pelvic disruption (10 [25%]), genitoperineal mutilation (19 [48%]), eye injury (6 [15%]), or skull fracture (6 [15%]). The fatality rate was higher in patients with UEA than in those without (12 [30%] v. 7 [12%], p = 0.022). Conclusion Upper-extremity amputation is more prevalent with AP-IED than APM. Presence of UEA is associated with more severe injury and increased risk of death in AP-IED victims. Upper-limb injury has significant consequences for
rehabilitation from LEA, which universally accompanies UEA in AP-IED victims. Upper-extremity injury should be amenable to prevention by innovative personal protective equipment designed to protect the flexed elbow.

Webster CE, Clasper J, Gibb I, Masouros SD. Environment at the time of injury determines injury patterns in pelvic blast. J ROY ARMY MED CORPS 2018; 165:15-17.

Abstract
The use of explosives by terrorists, or during armed conflict, remains a major global threat. Increasingly, these events occur in the civilian domain, and can potentially lead to injury and loss of life, on a very large scale. The environment at the time of detonation is known to result in different injury patterns in casualties exposed to blast, which is highly relevant to injury mitigation analyses. We describe differences in pelvic injury patterns in relation to different environments, from casualties that presented to the deployed UK military hospitals in Iraq and Afghanistan. A casualty on foot when injured typically sustains an unstable pelvic fracture pattern, which is commonly the cause of death. These casualties die from blood loss, meaning treatment in these should focus on early pelvic haemorrhage control. In contrast, casualties injured in vehicle present a different pattern, possibly caused by direct loading via the seat, which does not result in pelvic instability. Fatalities in this cohort are from injuries to other body regions, in particular the head and the torso and who may require urgent neurosurgery or thoracotomy as life-saving interventions. A different strategy is therefore required for mounted and dismounted casualties in order to increase survivors.

Abstract
PURPOSE To describe the combat-related injuries cured by Chinese Level 2 medical treatment facility (CHN L2) in Mali from 1 March 2016 to 1 March 2018, including type of weapon, mortality, nature of injuries, degree and location of injuries and surgical procedures. METHODS : A retrospective, descriptive study of 176 injured cases that met the terrorist attacks was conducted. The medical data were collected by an electronic database system. All collected data were entered into an Excel spreadsheet for calculation. RESULTS We found that improvised explosive devices (114/176, 65%) were the most commonly used weapons of attack in Mali. 68.75% of the injuries (121/176) were classified as 'minor injuries according to Abbreviated Injury Scale score. As one patient may suffer multiple injuries, each location and nature of injuries was counted separately. Surface injuries were the top (116/197, 58.88%), followed by orthopaedic injuries (52/197, 26.39%) and internal injuries (29/197, 14.72%). The extremities were the most frequently injured body parts (144/197, 73.09%). We operated 175 surgeries to deal with the 176 combat-related injuries, which accounted for 40.05% of all 437 surgeries. The surgical debridement to remove fragments of explosive was the most frequently performed surgery. We also admitted 20 cases (18/176, 34%) into intensive care unit and transferred 40 cases to Level 3 medical facility. CONCLUSION : Peacekeepers taking protective measures for head and trunk frequently got surface injuries. And their unprotected extremities often got injured. The fragment removal was the top surgery and the damage control surgery was the highly technical nature surgery we performed. Chinese military should offer advanced surgical training course to military surgeons who carry out overseas operations.

Abstract
BACKGROUND Having served more than 4000 personnel including the peacekeeping troops, UN police and civilian staff, the Chinese Peacekeeping Level 2 Military Hospital has accumulated 1235 inpatient medical records in 4 years. Assessment of the records stored in the CHN L2 identified that the data collected by different teams were incoherent and highlighted the need for implementation of a hospital-based combat injury registry and the establishment of a combat injury surveillance system. METHODS A one-page, 21-item registry form was designed to collect general information about the injuries, including such data as demographics, injury event, severity, diagnosis and treatment, and outcome. All relevant personnel was required to undergo a 2-day training in order to master the use of the registry form. The new registry form was used to collect the data on all of the cases recorded in the CHN L2 between 26 April 2014 and 31 March 2017. RESULTS Analysis of the collected data identified improvised explosive device as the most common (44.95%) mechanism of combat injury in Sector East of MINUSMA. Anefis, the centre of the UN logistic transit, was identified as the location where most of the combat injuries (42.20%) occurred. Based on these results, certain suggestions that addressed this threat were given to the Operation department in Sector East of MINUSMA. CONCLUSION A hospital-based combat injury registry was successfully developed and implemented in the Chinese Peacekeeping Level 2 Hospital. It can provide data to support the policy changes to minimise the impact of combat injuries on peacekeeping troops. The designed registry form provides more accurate estimates of the magnitude of the morbidity due to different causes in the battlefield and lays a foundation for an injury surveillance system.

Abstract
INTRODUCTION Gunshot wounding (GSW) is the second most common mechanism of injury in warfare after explosive injury. The aim of this study was to define the clinical burden of GSW placed on UK forces throughout the recent Iraq and Afghanistan conflicts. METHODS This study was a retrospective review of data from the UK Military Joint Theatre Trauma Registry (JTTR). A JTTR search identified records within the 12 year period of conflict between 19 Mar 2003 and 27 Oct 2014 of all UK military GSW casualties sustained during the complete timelines of both conflicts. Included cases had their clinical timelines and treatment further examined from time of injury up until discharge from hospital or death. RESULTS There were 723 casualties identified (177 fatalities, 546 survivors). Median age at the time of injury was 24 years (range 18-46 years), with 99.6% of casualties being male. Most common anatomical locations for injury were the extremities, with 52% of all casualties sustaining extremity GSW, followed by 16% GSW to the head, 15% to the thorax, and 7% to the abdomen. In survivors, the rate of extremity injury was higher at 69%, with head, thorax and abdomen injuries relatively lower at 5%, 11% and 6% respectively. All GSW casualties had a total of 2827 separate injuries catalogued. A total of 545 casualties (523 survivors, 22 fatalities) underwent 2357 recorded surgical procedures, which were carried out over 1455 surgical episodes between admission to a deployed medical facility and subsequent transfer to the Royal Centre for Defence Medicine (RCDM) in the UK. This gave a median of 3 (IQR 2-5) surgical procedures within a median of 2 (IQR 2-3) surgical episodes per casualty. Casualties had a combined length of stay (LoS) of 25 years within a medical facility, with a mean LoS in a deployed facility of 1.9 days and 14 days in RCDM. CONCLUSION These findings define the massive burden of injury associated with battlefield GSW and underscore the need for further research to both reduce wound incidence and severity of these complex injuries.

Abstract
IntroductionThroughout the last half century, blast injuries have been a common occurrence to UK military personnel during combat operations. This study investigates casualty data from three different military operations to determine whether survivability from blast injuries has improved over time and whether the tactics used could have influenced the injuries sustained.MethodsCasualty data from operations in Northern Ireland, Iraq and Afghanistan were reviewed and found to contain a total of 2629 casualties injured by improvised explosive devices. The injury severities were examined and the suitability of comparison between conflicts was considered.ResultsThe case fatality rate and mean severity score sustained remained consistent among the operations included in this study. Using the New Injury Severity Score, the probabilities of survival were calculated for each separate operation. The body regions injured were identified for both fatalities and survivors. Using this information, comparisons of injury severities sustained at an Abbreviated Injury Scale of 3 and above (identified as a threshold for fatal injury) were conducted between the different operations.ConclusionsThe data showed that as operations changed over time, survivability improved and the proportions of body regions injured also changed; however, this study also highlights how studying casualty data from different conflicts without taking account for the contextual differences may lead to misleading conclusions.

Abstract
OBJECTIVE To describe pattern 1 injuries caused by the antipersonnel improvised explosive device (AP-IED) in comparison to those previously described for antipersonnel mines (APM). DESIGN Prospective cohort study of 100 consecutive pedestrian victims of an AP-IED, with traumatic amputation without regard for gender, nationality or military status. SETTING Multinational Medical Unit at Kandahar Air Field, Afghanistan. PARTICIPANTS One hundred consecutive patients, all male, 6-44 years old. MAIN OUTCOME MEASURES The details of injuries were recorded to describe the pattern and characterise the injuries suffered by the target of AP-IEDs. The level of amputation, the level of soft tissue injury, the fracture pattern (including pelvic fractures) as well as perineal, gluteal, genital and other injuries were recorded. RESULTS Victims of AP-IED were more likely, compared with APM victims, to have multiple amputations (70.0% vs 10.4%; p<0.001) or genital injury (26% vs 13%; p=0.007). Multiple amputations occurred in 70 patients: 5 quadruple amputations, 27 triple amputations and 38 double amputations. Pelvic fracture occurred in 21 victims, all but one of whom had multiple amputations. Severe perineal, gluteal or genital injuries were present in 46 patients. Severe soft tissue injury was universal, with injection of contaminated soil along tissue planes well above entry sites. There were 13 facial injuries, 9 skull fractures and 3 traumatic brain injuries. Eleven eye injuries were seen; none of the victims with eye injuries were wearing eye protection. The casualty fatality rate was at least 19%. The presence of more than one amputation was associated with a higher rate of pelvic fracture (28.6% vs 3.3%; p=0.005) and perineal-gluteal injury (32.6% vs 11.1%; p=0.009). CONCLUSION The injury pattern suffered by the target of the AP-IED is markedly worse than that of conventional APM. Pelvic binders and tourniquets should be applied at the point of injury to patients with multiple amputations or perineal injuries.

Abstract
INTRODUCTION Improvised Explosive Devices (IED) are the primary wounding mechanism for casualties in Operation Enduring Freedom. Patients can sustain devastating traumatic amputations, which are unlike injuries seen in the civilian trauma sector. This is a database analysis of the largest patient registry of multiple traumatic amputations. METHODS The Joint Theater Trauma Registry was queried for patients with a traumatic amputation from 2009 to 2012. Data obtained included the Injury Severity Score (ISS), Glasgow Coma Score (GCS), blood products, transfer from theatre, and complications including DVT, PE, infection (Acinetobacter and fungal), acute renal failure, and rhabdomyolysis. Comparisons were made between number of major amputations (1-4) and specific outcomes using χ2 and Pearson's rank test, and multivariable logistic regression was performed for 30-day survival. Significance was considered with p<0.05. RESULTS We identified 720 military personnel with at least one traumatic amputation: 494 single, 191 double, 32 triple, and 3 quad amputees. Average age was 24.3 years (18-46), median ISS 24 (9-66), and GCS 15 (3-15). Tranexamic acid (TXA) was administered in 164 patients (23%) and tourniquets were used in 575 (80%). Both TXA and tourniquet use increased with increasing number of amputations (p<0.001). Average transfusion requirements (in units) were packed red blood cells (PRBC) 18.6 (0-142), fresh frozen plasma (FFP) 17.3 (0-128), platelets 3.6 (0-26), and cryoprecipitate 5.6 (0-130). Transfusion of all blood products increased with the number of amputations (p<0.001). All complications tested increased with the number of amputations except Acinetobacter infection, coagulopathy, and compartment syndrome. Transfer to higher acuity facilities was achieved in 676 patients (94%). CONCLUSION Traumatic amputations from blast injuries require significant blood product transfusion, which increases with the number of amputations. Most complications also increase with the number of amputations. Despite high injury severity, 94% of traumatic amputation patients who are alive upon admission to a role II/III facility will survive to transfer to facilities with higher acuity care.

Abstract
INTRODUCTION As North Atlantic Treaty Organization (NATO) countries begin troop withdrawal from Afghanistan, military medicine needs programs for combat surgeons to retain the required knowledge and surgical skills. Each military branch runs programs at various Level I academic trauma centers to deliver predeployment training and provide a robust trauma experience for deploying surgeons. Outside of these successful programs, there is no system-wide mechanism for nondeploying military surgeons to care for a high volume of critically ill trauma patients on a regular basis in an educational environment that promotes continued professional development. We hypothesize that fully integrated military-civilian relationship regional Level I trauma centers provide a surgical experience more closely mirroring that seen in a Role III hospital than local Level II and Level III trauma center or medical treatment facilities. METHODS We characterized the Level I trauma center practice using the number of trauma resuscitations, operative trauma/acute care surgery procedures, number of work shifts, operative density (defined as the ratio of operative procedures/days worked), and frequency of educational conferences. The same parameters were collected from two NATO Role III hospitals in Afghanistan during the peak of Operation Enduring Freedom. Data for two civilian Level II trauma centers, two civilian Level III trauma centers, and a Continental United States Military Treatment Facility without trauma designation were collected. RESULTS The number of trauma resuscitations, number of 24-hour shifts, operative density, and educational conferences are shown in the table for the Level I trauma center compared with the different institutions. Civilian center trauma resuscitations and operative density were highest at the Level I trauma center and were only slightly lower than what was seen in Afghanistan. Level II and III trauma centers had lower numbers for both. The Level I trauma center provided the most frequent educational opportunities. CONCLUSION In a Level I academic trauma center integrated program, military and civilian surgeons have the same clinical and educational responsibilities: rounding and operating, managing critical care patients, covering trauma/acute care surgery call, and mentoring surgery residents in an integrated residency program. The Level I trauma center experience most closely mimics the combat surgeon experience seen at NATO Role III hospitals in Afghanistan compared with other civilian trauma centers. At high-volume Level I trauma centers, military surgeons will have a comprehensive trauma practice, including dedicated educational opportunities. We recommend integrated programs with Level I academic trauma centers as the primary mechanism for sustaining military combat surgical skills in the future.

Abstract
Although the incidence of hip fractures is decreasing, the overall prevalence continues to increase because of an aging population. People older than 65 suffer fractures at a rate of 0.6% per year--2% per year for persons older than 85. One in 5 patients suffering a hip fracture will die within a year. Additionally, the emergency physician must consider entities such as avascular necrosis, compartment syndrome, and muscular disruption. This article reviews patterns and complications of acute hip and thigh injuries and clinically relevant diagnostic, anesthetic, and treatment options that facilitate timely, appropriate, and effective emergency department management.
