The Wounded; Healing, With New Limbs and Fragile Dreams
By JULIET MACUR; Correction AppendedIt was a victory for Lance Cpl. Matthew Schilling to walk into the upper gallery of the House of Representatives onJan. 31 for the State of the Union address. He wore his dress blues and a prosthetic leg. Five months earlier, he
had been carried on a stretcher, wounded and bleeding, into a hospital in Iraq after a roadside bomb exploded 10feet from him…. The blast tore through his right foot and calf……Corporal Schilling's Marine Corps unit and a victimof the same blast, Lance Cpl. Mark Beyers, wheeled up to him at the Walter Reed physical therapy clinic. Corporal
Beyers's right arm and leg were amputated in Iraq . Since Aug. 26, when they were wounded, the two marines eachhave endured some 20 operations in three countries. Charting their care over the ensuing months, beginning justhours after the blast, has revealed a journey of medical setbacks and emotional turmoil. Among the more than ….About an hour later, Corporals Schilling and Beyers were in surgery at the nearby Al Asad Military Base. It was the
first of 13 operations they would endure in eight days, during stays at five hospitals in three countries. A doctoramputated Corporal Schilling's right leg below the knee. Corporal Beyers, with severe lung injuries, was in worse
shape. Doctors amputated his right lower leg and his entire right arm, including the shoulder; shrapnel haddestroyed his shoulder joint and just missed slicing his carotid artery, doctors said. For the next week he would bein an induced coma …After 19 operations and 63 days in hospitals, Corporal Beyers went home in October for a
visit..
…16,653 Americans wounded in Iraq are 387 amputees,including 62 who, like Corporal Beyers, have lost more than onelimb, said Lt. Col. Paul Pasquina, chief of physical medicine andrehabilitation at Walter Reed. The amputations, traumaticthough they are, are often accompanied by painfulcomplications. "It's not as easy as putting on even the mosthigh-tech prosthetic and just walking off," Colonel Pasquinasaid….
