Injuries from roadside improvised explosive devices.

BACKGROUND After the invasion of Iraq in April 2003, coalition forces have remained in the country in a bid to maintain stability and support the local security forces. The improvised explosive device (IED) has been widely used by the insurgents and is the leading cause of death and injury among Coalition troops in the region. METHOD From January 2006, data were prospectively collected on 100 consecutive casualties who were either injured or killed in hostile action. Mechanism of injury, new Injury Severity Score (NISS), The International Classification of Disease-9th edition diagnosis, anatomic pattern of wounding, and operative management were recorded in a trauma registry. The weapon incident reports were analyzed to ascertain the type of IED employed. RESULTS Of the 100 casualties injured in hostile action, 53 casualties were injured by IEDs in 23 incidents (mean 2.3 casualties per incident). Twenty-one of 23 (91.3%) of the IEDs employed were explosive formed projectile (EFP) type. Twelve casualties (22.6%) were either killed or died of wounds. Median NISS score of survivors was 3 (range, 1-50). All fatalities sustained unsurvivable injuries with a NISS score of 75. Primary blast injuries were seen in only 2 (3.8%) and thermal injuries in 8 casualties (15.1%). Twenty (48.7%) of survivors underwent surgery by British surgeons in the field hospital. At 18 months follow, all but one of the United Kingdom Service personnel had returned to military employment. CONCLUSIONS The injury profile seen with EFP-IEDs does not follow the traditional pattern of injuries seen with conventional high explosives. Primary blast injuries were uncommon despite all casualties being in close proximity to the explosion. When the EFP-IED is detonated, the EFP produced results in catastrophic injuries to casualties caught in its path, but causes relatively minor injuries to personnel sited adjacent to its trajectory. Improvements in vehicle protection may prevent the EFP from entering the passenger compartments and thereby reduce fatalities.

A review of casualties during the Iraqi insurgency 2006–A British field hospital experience

BACKGROUND Following the invasion of Iraq in April 2003, British and coalition forces have been conducting counter-insurgency operations in the country. As this conflict has evolved from asymmetric warfare, the mechanism and spectrum of injury sustained through hostile action (HA) was investigated. METHOD Data was collected on all casualties of HA who presented to the British Military Field Hospital Shaibah (BMFHS) between January and October 2006. The mechanism of injury, anatomical distribution, ICD-9 diagnosis and initial discharge information was recorded for each patient in a trauma database. RESULTS There were 104 HA casualties during the study period. 18 were killed in action (KIA, 21%). Of the remaining 86 surviving casualties, a further three died of their wounds (DOW, 3.5%). The mean number of diagnoses per survivor was 2.70, and the mean number of anatomical regions injured was 2.38. Wounds to the extremities accounted for 67.8% of all injuries, a percentage consistent with battlefield injuries sustained since World War II. Open wounds and fractures were the most common diagnosis (73.8%) amongst survivors of HA. Improvised explosive devices (IEDs) accounted for the most common cause of injury amongst casualties (54%). CONCLUSIONS Injuries in conflict produce a pattern of injury that is not seen in routine UK surgical practice. In an era of increasing surgical sub-specialisation, the deployed surgeon needs to acquire and maintain a wide range of skills from a variety of surgical specialties. IEDs have become the modus operandi for terrorists. In the current global security situation, these tactics can be equally employed against civilian targets. Therefore, knowledge and training in the management of these injuries is relevant to both military and civilian surgeons.

Skill sets and competencies for the modern military surgeon: lessons from UK military operations in Southern Afghanistan

INTRODUCTION British military forces remain heavily committed on combat operations overseas. UK military operations in Afghanistan (Operation HERRICK) are currently supported by a surgical facility at Camp Bastion, in Helmand Province, in the south of the country. There have been no large published series of surgical workload on Operation HERRICK. The aim of this study is to evaluate this information in order to determine the appropriate skill set for the modern military surgical team. METHOD A retrospective analysis of operating theatre records between 1st May 2006 and 1st May 2008 was performed. Data was collated on a monthly basis and included patient demographics, operation type and time of operation. RESULTS During the study period 1668 cases required 2210 procedures. Thirty-two per cent were coalition forces (ISAF), 27% were Afghan security forces (ANSF) and 39% were civilians. Paediatric casualties accounted for 14.7% of all cases. Ninety-three per cent of cases were secondary to battle injury and of these 51.3% were emergencies. The breakdown of procedures, by specialty, was 66% (1463) orthopaedic, 21% (465) general surgery, 6% (139) head and neck, 5% (104) burns surgery and a further 4% (50) non-battle, non-emergency procedures. There was an almost twofold increase in surgical workload in the second year (1103 cases) compared to the first year of the deployment (565 cases, p<0.05). DISCUSSION Surgical workload over the study period has clearly increased markedly since the initial deployment of ISAF forces to Helmand Province. A 6-week deployment to Helmand Province currently provides an equivalent exposure to penetrating trauma as 3 years trauma experience in the UK NHS. The spectrum of injuries seen and the requisite skill set that the military surgeon must possess is outside that usually employed within the NHS. A number of different strategies; including the deployment of trainee specialist registrars to combat hospitals, more focused pre-deployment military surgery training courses, and wet-laboratory work are proposed to prepare for future generations of surgeons operating in conflict environments.

Penetrating Missile Injuries During the Iraqi Insurgency

INTRODUCTION Since the invasion of Iraq in 2003, the conflict has evolved from asymmetric warfare to a counter-insurgency operation. This study investigates the pattern of wounding and types of injuries seen in casualties of hostile action presenting to a British military field hospital during the present conflict. PATIENTS AND METHODS Data were prospectively collected on 100 consecutive patients either injured or killed from hostile action from January 2006 who presented to the sole coalition field hospital in southern Iraq. RESULTS Eighty-two casualties presented with penetrating missile injuries from hostile action. Three subsequently died of wounds (3.7%). Forty-six (56.1%) casualties had their initial surgery performed by British military surgeons. Twenty casualties (24.4%) sustained gunshot wounds, 62 (75.6%) suffered injuries from fragmentation weapons. These 82 casualties were injured in 55 incidents (mean, 1.49 casualties; range 1-6 casualties) and sustained a total 236 wounds (mean, 2.88 wounds) affecting a mean 2.4 body regions per patient. Improvised explosive devices were responsible for a mean 2.31 casualties (range, 1-4 casualties) per incident. CONCLUSIONS The current insurgency in Iraq illustrates the likely evolution of modern, low-intensity, urban conflict. Improvised explosive devices employed against both military and civilian targets have become a major cause of injury. With the current global threat from terrorist bombings, both military and civilian surgeons should be aware of the spectrum and emergent management of the injuries caused by these weapons.

Management Of Unstable Cervical Spine Injuries In Southern Iraq During OP TELIC

Introduction Cervical spine fractures and dislocations are uncommon injuries that can have serious neurological consequences. These injuries require adequate stabilisation to prevent further spinal cord injury during transfer between hospitals. Evacuation often requires a combination of road ambulance, helicopter and fixed wing aircraft from military hospitals. This paper outlines the neck injuries sustained during Op Telic and discusses the need for Halo vests to be available at Role 3. Methodology The MND(SE) Hospital databases were used to identify all casualties admitted with either a “Cervical” or “Neck” injury. The databases covered the period from 24 March 2003 until 15 April 2004. The diagnoses were categorised into minor and serious cervical spine injuries. We defined a serious cervical spine injury as either a fracture or dislocation. We looked at the discharge letters of all casualties evacuated to a Role 4 hospital to confirm whether the casualties had serious cervical spine injuries. Results Forty seven casualties were admitted and all were British except three, two Iraqi civilians and one US soldier. Thirty three casualties were returned to their unit for duty, or discharged at the airhead on return to the UK. Fourteen casualties required hospital treatment. There were five serious cervical spine injuries over the study period which included one Hangman’s fracture of C2, one flexion compression injury of C5, one flexion compression injury of C7, one unifacetal dislocation and one bifacetal dislocation. Conclusions Five casualties were treated at MND(SE) Hospital for serious injuries to the cervical spine. Two patients were transferred without Halo stabilisation after failing to obtain halos in Iraq. One casualty was kept until a Halo was flown out from the UK. Recommendations All unstable cervical spine fractures should be stabilised with a Halo Vest prior to transfer from Role 3. Halo Rings and Vests should be available at Role 3 facilities.

Surgical advances during the First World War: the birth of modern orthopaedics.

The First World War (1914–1918) was the first truly industrial conflict in human history. Never before had rifle fire and artillery barrage been employed on a global scale. It was a conflict that over 4 years would leave over 750 000 British troops dead with a further 1.6 million injured, the majority with orthopaedic injuries. Against this backdrop, the skills of the orthopaedic surgeon were brought to the fore. Many of those techniques and systems form the foundation of modern orthopaedic trauma management. On the centenary of ‘the War to end all Wars’, we review the significant advances in wound management, fracture treatment, nerve injury and rehabilitation that were developed during that conflict.

The roadside bomb in Iraq: Emerging patterns of injury

Background: Following the invasion of Iraq in April 2003, Coalition forces have been conducting counter-insurgency operations in a bid to maintain security within in the country. The roadside bomb or improvised explosive device (IED) has become the weapon of choice of the terrorist and is the leading cause of death and injury amongst coalition troops in the region. Method: From January to October 2006, data was collected on all casualties who were injured or killed by an IED. Mechanism of injury, new Injury Severity Score (NISS), anatomical pattern of wounding, operative management and 1-year follow-up was recorded in a trauma database. Results: Fifty-three casualties were injured by IEDs in 23 incidents (mean 2.3 casualties per incident). Twelve (22.6%) were killed or died of wounds. Mean NISS score of survivors was 5.4 (range 1-50). A mean 2.78 body regions were injured per casualty. Limb injuries were present in 45 (84.9%) of casualties, but primary blast injuries were seen in only 9 (14%). Conclusions: IEDs do not follow the traditional pattern of injuries as seen from conventional explosives. Primary blast injuries were minimal despite all casualties being in close proximity to the explosion. The explosive formed projectile (EFP) appears to cause catastrophic injuries to casualties caught in its path, but causes relatively minor injuries to personnel sited adjacent to its trajectory. Improved vehicle protection may prevent the EFP from entering the passenger compartments and thereby reduce coalition troop fatalities.
