- A new type of prosthetics namely Itap (intraosseous transcutaneous amputation prosthesis) has transformed the life of amputees by allowing direct attachment of the limbs to their skeleton.
- Itap is an implant is based on the principle of growth of skin around the deer’s antlers. The antler bone is porous under the skin and the skin grows into these pores for firm attachment.
- Itap is for the skin and the tissue to merge into the metal implant, creating a seal that can prevent bacterial infections and allows secure attachment and carrying of weights in a normal way.
- Traditional ball and socket prosthetics involves the placing a socket over the soft tissue of the stump. This:
- Provided no sensation or understanding to the person about where his legs are.
- Causes discomfort while walking as the socket rubbed against the soft tissue, a problem that aggravated during hot weather, making the person dependent on crutches at times.
- Is not ideal for people with skin conditions such as dermatitis and eczema, who would often not opt for prosthetics.
- However, itap:
- Involves insertion of a metal implant that forms a direct interface with the bone and sticks out through the skin for the prosthetic to be attached.
- This improves the ability to walk as the person constantly knows where his foot is.
- Can be used for the war-wounded as short stumps arising from improved explosive device blasts results in problems with ball and socket fittings.
- Can be quickly attached and detached.
- Has a release mechanism to prevent damage to the bone or implant in case of a fall.
