Background. To present the first case of the tertiary blast injury to the intestine, and the tertiary blast injury in general. Case report. A parachutist of the Army of Serbia and Montenegro was injured when descended from the 1 200m height by parachute which did not expand. The force of stroke to the ground, caused the reactive transfer of energy and the subsequent blast injury to the intestine. After 24 hours, the secondary perforation of the small intestine, contusioned by the blast, developed which was the indication of explorative laparotomy. The resectioned small intestine showed the histologic characteristics of a blast injury, so the tertiary blast injury was diagnosed on the basis of these and of the mechanism of the injury. Conclusion. Tertiary blast injuries fall into the group of indirect blast injuries. The only difference between indirect injuries as compared to direct ones, is in the manner of inflicting, otherwise the traumatic mechanisms are alike, and include the transfer of the energy of stroke through the tissue of different density.
