Cripples to see Lorenz.Adolf Lorenz (1854 - February 12, 1946) was an Austrian orthopedic surgeon. During the 1880's he developed an allergic skin reaction to carbolic acid, which was used in operating rooms, which prevented him from performing traditional surgical operations. He continued in the medical profession as a "dry surgeon", by treating patients without cutting into skin or tissue and given the nickname "The Bloodless Surgeon of Vienna". His techniques became known as bloodless surgery, reflecting his noninvasive techniques. Lorenz was renowned for his treatment of congenital dislocation of the hip in children. He created a manipulative treatment for club feet, which involved stretching or breaking the tendons, ligaments, and epiphyseal plates until the foot was properly aligned. Once alignment was achieved, Lorenz applied a cast so that the foot healed in the corrected position. Also, by using traction and pulleys, Lorenz developed a mechanism for treatment of scoliosis. He was the father of famed behavioralist Konrad Lorenz. He died in 1946 at the age of 91 or 92.
