A soldier who has left an armored vehicle and who is on foot is considered dismounted. Detonation of an improvised explosive device (IED) can have a devastating effect on the exposed soldier.

Features of dismounted complex blast injury (CBI):

(1) high-energy injuries to both lower extremities

(2) high-energy injuries to one or both upper extremities (often the non-dominant)

(3) high-energy injuries to the pelvis and perineum

(4) genitourinary and intra-abdominal trauma

(5) traumatic brain injury


Management may involve bilateral proximal transfemoral amputations.
