As noted earlier Galen was from Peragamon and he travelled to Rome. Many orthopaedic surgeons consider him the"The father of Sports Medicine".

He gave a god accont of the skeleton and the nerves. He was the first to describe a cervical rib.

He described osteomylitis, the formation of sequestra and their treatment.

He also coined the words kyphosis, lodosis and scoliosis and described some treatment for these conditions.

David L McKintosh was the first sougeon to do operate successfully on a case af Anterior Cruciate ligament injury. This injury used to cripple skiers and ice dancers in the prime of life. Modern orthopaedics has allowed much smaller incisions through which you can intrduce implants, enabling the surgery to be done through smaller incisions and more successfully, allowing numerous athletes to return to their sport and profession.

In the meanwhile Ayurveda spread beyond India through the capture of Sind (India) by the Arabs who translated all the works of Sushruta.
