Object. “Operation Enduring Freedom” is the US war effort in Afghanistan in its global war on terror. One US military neurosurgeon is deployed in support of Operation Enduring Freedom to provide care for both battlefield inju- ries and humanitarian work. Here, the authors analyze a 24-month neurosurgical caseload experience in Afghanistan. Methods. Operative logs were analyzed between October 2007 and September 2009. Operative cases were divided into minor procedures (for example, placement of an intracranial pressure monitor) and major procedures (for example, craniotomy) for both battle injuries and humanitarian work. Battle injuries were defined as injuries sus- tained by soldiers while in the line of duty or injuries to Afghan civilians from weapons of war. Humanitarian work consisted of providing medical care to Afghans. Results. Six neurosurgeons covering a 24-month period performed 115 minor procedures and 210 major surgical procedures cases. Operations for battlefield injuries included 106 craniotomies, 25 spine , and 18 miscella- neous surgeries. Humanitarian work included 32 craniotomies (23 for trauma, 3 for tumor, 6 for other reasons, such as cyst fenestration), 27 spine surgeries (12 for degenerative conditions, 9 for trauma, 4 for myelomeningocele closure, and 2 for the treatment of infection), and 2 miscellaneous surgeries. Conclusions. Military neurosurgeons have provided surgical care at rates of 71% (149/210) for battlefield in- juries and 29% (61/210) for humanitarian work. Of the operations for battle trauma, 50% (106/210) were cranial and 11% (25/210) spinal surgeries. Fifteen percent (32/210) and 13% (27/210) of operations were for humanitarian cranial and spine procedures, respectively. Overall, military neurosurgeons in Afghanistan are performing life-saving cranial and spine stabilization procedures for battlefield trauma and acting as general neurosurgeons for the Afghan community.

Minor procedures included placement of an ICP monitor, ventriculostomy, cervical spine clearance by ac- tive flexion-extension under fluoroscopy, lumbar drainage or puncture, halo orthosis placement, and placement of Gardner-Wells tongs for cervical traction.

Mechanism of Combat-Related Injuries in Soldiers and Civilians A difference in the proportion of surgeries for soldiers in comparison with Afghan citizens was observed. The proportion of GSW victims who required neurosurgery for their wounds was between 33 and 39% for soldiers and 47% for Afghan locals. We attribute this difference to the wide use of helmets and body armor by soldiers.3,29 The proportion of NATO soldiers requiring neurosurgery is higher than the overall injury rates previously reported in the literature.3,14,16,19,25,26,28–30,32,36,37 A recent report noted 6609 injuries in 1566 US soldiers during combat in Iraq and Afghanistan.26 In that study, the proportions of inju- ries caused by GSW and explosions were 18 and 78%, re- spectively. 26 The authors attribute differences in the data they present (38 and 54%, respectively, Table 2) to the dif- ferent preferences in enemy tactics in Afghanistan (use of direct- and indirect-fire weapons) and Iraq (use of IEDs). Also, our data reflect the caseload at an inpatient war- time hospital rather than overall wartime soldier injury patterns. Interestingly, military neurosurgeons are asked to provide forensic information to aid in the analysis of evolving enemy tactics. Lessons Learned in the Operative Management of Penetrating Head Injuries From IEDs The opposing fighters use IEDs to incapacitate or de- stroy personnel and equipment. These devices are usually constructed from conventional military high-explosive weapons (e.g., shells) attached to a detonating mechanism.7,13,14,22,24 Such IED attacks in Afghanistan and Iraq are common, accounting for 48% (2560/5283) and 65% (23,650/36,222) of all US soldier deaths and in- juries, respectively.1 Our experience with penetrating cra- nial injuries due to IED blast reveal cranial injuries from ball bearings, nails, metal fragments, and rocks (Cases 1 and 2; Figs. 2, 3, and 5).
