Conversion from external fixation to definitive fixation: periarticular injuries.

: Extremity injuries sustained by uniformed service combatants pose a significant challenge to military orthopaedic surgeons. The wounding mechanisms in Operation Iraqi Freedom and Operation Enduring Freedom consist of blasts, penetrating injuries, and blunt injuries. The mortality of warriors has decreased overall because of the improvements in head, neck, and torso body armor. Consequently, the severity of extremity wounds has increased. Because of the far-forward surgical assets (surgeons and advanced equipment), these patients are stabilized rapidly and their injured extremities are treated early (ie, revascularized, debrided, stabilized). However, multiple challenges exist in the timing of definitive reconstructive efforts once these injured service members return to military medical centers in the continental United States.
