In 1920,  Professor Janos Ertl, Sr., MD, of Hungary, developed the Ertl procedure in order to return a high number of amputees to the work force. During this time amputees had significant problems with pain and difficulty with prosthetic wear. Today the Ertl Bridge/procedure (pictured above) is responsible for improving the lives of amputees worldwide . The continued success of the Ertl Procedure is now spearheaded by Ertl’s grandsons, Dr. Jan Ertl of The University of Indiana, Indianapolis, Dr. William Ertl of The University of Oklahoma, Health Sciences Center and Dr. Christian Ertl at Western Michigan University Homer Stryker M.D. School of Medicine
