BackgroundGunshot wounds of the lower extremities are always serious injuries, especially in cases in which bone is affected. Contamination and extensive tissue damage can be life-threatening for the patient and severely affect the function of the extremity. Contamination and local infections with multidrug resistant pathogens are regularly encountered particularly in casualties evacuated from crisis regions. Treatment of this special type of injury, which differs in the form and extent from conventional high-energy trauma of the lower extremities, usually requires lengthy and extensive therapy algorithms in order to preserve the affected extremity.Patients And MethodsBased on the results of 34 gunshot wounds of the lower extremities which were surgically treated in this department between 2005 and 2011, this article reports on procedures used for wound management, soft tissue reconstruction and restoration of bone continuity. This group included 18 patients with a total of 20 gunshot-related fractures, 40% of which affected the lower leg and 35% the thigh. The affected extremities could be salvaged in all cases.ResultsThe therapeutic spectrum required for bone reconstruction after soft tissue coverage demonstrated in these case examples ranged from conventional osteosynthesis with or without local cancellous bone transplant with platelet-rich plasma, to healing in a fixator, bone resection and the Masquelet method, distraction osteogenesis using a fixator in order to restore continuity and definitive secondary extension using an intramedullary skeletal kinetic distractor (ISKD) nail. Out of 15 bullet fractures affecting large tubular bones 8 could be healed without any shortening, axis deviation or malrotation. In 7 cases definitive shortening by an average of 20 mm (minimum 10 mm and maximum 40 mm) was necessary. The average treatment time before full weight-bearing was achieved within tolerable pain limits was 66 weeks (minimum 4 weeks and maximum 267 weeks). Secondary osteitis and osteomyelitis following primary restoration was detected in only one case.ConclusionThese results show that the treatment of gunshot wounds of the lower extremities is time-consuming and extensive and requires the complete spectrum of modern trauma surgery. Despite the high risk of complications during treatment it is possible and feasible to apply procedures that preserve the extremities.
