A signature of current conflicts is the use of buried improvised explosive devices to cause injury to military personnel and damage to their vehicles. Explosive devices also cause injuries to non-military populations in current and former conflict zones. The nature and placement of the explosive charge has a marked effect on the loading experienced. In all situations, damage to tissues occurs when the energy and loading rate exceeds that which the human body can support. Currently, it is difficult to predict the various time-dependent effects of blast injury because of the complexities of the rapid initial accelerations, the loading geometries and the heterogeneous nature of the tissues that can be damaged. An outline of the ways in which one may study how explosive energy interacts with biological systems is presented along with a discussion of how the data generated can be used to develop improved, costeffective strategies for studying blast injury processes.

Masouros SD, Newell N, Bonner TJ, Ramasamy A, Hill AM, West ATH, Clasper JC, Bull AMJet al., 2012, A standing vehicle occupant is likely to sustain a more severe injury than one who has flexed knees in an under-vehicle explosion: A cadaveric study, 2012 IRCOBI Conference Proceedings - International Research Council on the Biomechanics of Injury, Pages: 289-295

The lower limb of military vehicle occupants has been the most injured body part due to undervehicle explosions in recent conflicts. Understanding the injury mechanism and causality of injury severity could aid in developing better protection. Therefore, we tested 4 different occupant postures (seated, brace, standing, standing with knee locked in hyper-extension) in a simulated under-vehicle explosion (solid blast) using our traumatic injury simulator in the laboratory; we hypothesised that occupant posture would affect injury severity. No skeletal injury was observed in the specimens in seated and braced postures. Severe, impairing injuries were observed in the foot of standing and hyper-extended specimens. These results demonstrate that a vehicle occupant whose posture at the time of the attack incorporates knee flexion is more likely to be protected against severe skeletal injury to the lower leg.

The outcomes of 261 nerve injuries in 100 patients were graded good in 173 cases (66%), fair in 70 (26.8%) and poor in 18 (6.9%) at the final review (median 28.4 months (1.3 to 64.2)). The initial grades for the 42 sutures and graft were 11 good, 14 fair and 17 poor. After subsequent revision repairs in seven, neurolyses in 11 and free vascularised fasciocutaneous flaps in 11, the final grades were 15 good, 18 fair and nine poor. Pain was relieved in 30 of 36 patients by nerve repair, revision of repair or neurolysis, and flaps when indicated. The difference in outcome between penetrating missile wounds and those caused by explosions was not statistically significant; in the latter group the onset of recovery from focal conduction block was delayed (mean 4.7 months (2.5 to 10.2) vs 3.8 months (0.6 to 6); p = 0.0001). A total of 42 patients (47 lower limbs) presented with an insensate foot. By final review (mean 27.4 months (20 to 36)) plantar sensation was good in 26 limbs (55%), fair in 16 (34%) and poor in five (11%). Nine patients returned to full military duties, 18 to restricted duties, 30 to sedentary work, and 43 were discharged from military service. Effective rehabilitation must be early, integrated and vigorous. The responsible surgeons must be firmly embedded in the process, at times exerting leadership.
