He developed it at Children's Hospital of The King's Daughters, in Norfolk, Virginia. The operation typically takes approximately two hours.:1277 Through two small incisions in the side of the chest, an introducer is pushed along posterior to the sternum and ribs, and anterior to the heart and lungs. Then a concave stainless steel bar is slipped under the sternum, through the incisions in the side of the chest. A third, smaller incision is made to insert a thoracoscope (small camera) used to help guide the bar. Taller patients, older patients, or patients requiring extensive correction may receive two or more bars. All bars may be placed through two incisions or additional incisions may be made. The bar is then flipped, and the sternum pops out. To support the bar and keep it in place, a metal plate called a stabilizer may be inserted with the bar on one side of the torso. PDS sutures may also be used in addition to the stabilizer. The stabilizer fits around the bar and into the ribcage. The bar and stabilizer are secured with sutures that dissolve in about six months.
