The first prosthesis may be functional today


The Egyptians used prosthesis to help people walk on foot amputations, according to a study by the University of Manchester (UK), released this week. The author of the study, the Egyptologist Jacky Finch, identified two artificial toes, one of them found in the limbs of a mummy, and has concluded that they could be the oldest prosthesis which has been reported.

One is an artifact of wood and leather three piece delMuseo Egyptian, and the second is an artificial finger made of a kind papier-mâché made from linen, glue and plaster is exposed in the British Museum in London. Finch is convinced that the prostheses, which date from 600 BC, were used to help amputees hundreds of years before the Romans used prosthetic legs.


To test this, the Egyptologist worked with two volunteers who lacked the right big toe and using exact replicas of Egyptian artifacts. Volunteers are asked to carry the replicas and wear sandals as of the time, and one of them was able to walk very effectively with both artificial fingers. The two volunteers

agreed that they felt especially comfortable with the prosthesis of the Cairo Museum, which has a hinge to facilitate movement, a beveled front edge and a flat bottom. In contrast, the British Museum prosthesis significantly deteriorated, which made it uncomfortable to use.

Finch explained in the medical journal The Lancet that the replicas overcame a series of tests, such as resistance to the forces involved in the process of walking, or the proportion and appearance are crucial factors for effective consideration exceeded the prótesis.También functionality, in terms of ease of putting them and remove them to keep clean, and, most importantly, the evaluation of users: in fact, prosthetics helped them walk better.

Finch recalls in his article that the big toe hold approximately 40% of the weight of the body and is responsible for the movement of propulsion when walking, but also notes that people who lose tend to adapt well.

deterioration London artificial finger and sophistication in the design of finger Cairo Finch led to the conclusion that "the fingers were taken by their owners in life and not simply added to the foot during mummification for religious or ritual. " "Until could test the replicas of both fingers with the help of volunteers and in laboratory conditions, still had doubts about whether they could help their owners to walk, "he says.

" solidly My findings suggest that both designs were capable of handling spare parts for the toe missing and therefore could be classified comoartefactos prosthetic, "says Finch in his article.

If this is the case, he concludes," it appears that the first signs of this branch of medicine should be clearly attributed to the ancient Egyptians. "
