During his work after 1934 at the Hospital for Ruptured and Crippled, Dr. Cobb developed and led the Margaret Caspary scoliosis clinic. At this time, little was known about scoliosis or its cause, and there were few effective treatments. Cobb experimented with various methods and concluded that the most effective approach was to use a turnbuckle plaster jacket in combination with spinal fusion. His studies of thousands of patients showed that only 10% of patients with scoliosis require such surgery. To obtain an accurate and consistent assessment of the severity of spinal deformity, so as to avoid unnecessary surgery, Cobb developed a simple and reliable method for measuring the angle of curvature which has become known as the Cobb angle.
John Robert Cobb died on March 24, 1967.
