The Jaipur leg is a rubber-based prosthetic leg produced by Dr. P. K . Sethi and Masterji Ram Chander in 1969 for victims of landmine explosions. Designed in, and named for Jaipur, India; the prosthetic leg was designed to be inexpensive, quick to fit and manufacture, and to be water-resistant. The main drawback to this design is that it is only suitable for below the knee amputees.

P. K. Sethi, Inventor of the Low-Tech Limb, Is Dead at 80
Dr. P. K. Sethi, who invented the affordable prosthesis called the Jaipur foot, which has helped millions of amputees in developing countries to lead normal lives, died Sunday in Jaipur, India. He was 80.
The cause was cardiac arrest, his family said.
The Jaipur foot, which has never been patented, is available in more than 25 countries, most of them poor, many of them with great numbers of land-mine victims. Unlike many high-priced prostheses in developed countries, it can be made by traditional craftsmen, lasts more than five years and costs about $30, making it affordable for mass distribution.
Pramod Karan Sethi was born on Nov. 28, 1927, in the ancient northern Indian city of Benares (now Varanasi), on the banks of the Ganges. His father was a professor of physics at Benares Hindu University. On completing his medical education in India and Britain, he became a lecturer in surgery at Sawai Man Singh Medical College and Hospital in Jaipur.
He became an orthopedic 矯形外科 surgeon by default. In 1958, his institution was about to be inspected for accreditation, and since there was no department of orthopedics, he was asked to start one at once. He always maintained that not being a qualified orthopedic surgeon helped him produce something that was genuinely new.
Dr. Sethi came up with his invention after years of extensive research. He was helped by Ramachandra Sharma, a semiliterate craftsman who had been teaching lepers to make handicrafts and who became his assistant.
The two made a foot of vulcanized rubber but found it too heavy and stiff. So they filled the shell with sponge rubber and modified the design. They used a stiff piece for the metatarsals 【解】中足骨（の）.and added microcellular rubber for the heel, cutting wedges at its upper end to make a universal joint.
Since 1971, when Dr. Sethi presented the foot to British orthopedic surgeons at Oxford, the Jaipur foot has revolutionized lives in war-torn countries. It is very flexible, allowing the wearer to run, climb trees or pedal bicycles. It is well suited to the needs of many Asian countries in which most people sit, eat, sleep and pray on the floor. Using the Jaipur foot, a Bollywood actor and dancer, Sudha Chandra, was even able to perform a demanding dance sequence in the movie musical “Nache Mayuri.”
The Jaipur foot was first used outside India in Afghanistan, which had the highest number of amputees in the world after the Soviet invasion, when Russian land mines caused thousands of wounds. It is also in heavy demand in Cambodia, Iraq, Kenya, Bangladesh and Nicaragua.
Dr. Sethi is survived by his wife, Sulochana, one son and three daughters.
Relations between Dr. Sethi and Mr. Sharma soured after Dr. Seti won a major international award. Mr. Sharma said he felt cheated after getting neither a share of the prize money nor any credit for its design. Though they later mended their relationship, the bond between them was never the same.
Mr. Sharma now works for Bhagwan Mahaveer Viklang Sahayata Samiti, a charity established in 1975 in Jaipur, which manufactures the foot on a large scale and provides it free to thousands of poor people.
