National Institute of Rehabilitation Training and Research through the following infrastructure: Head of the Department:Dr. Somnath Rout Prosthetics and orthotics science is now one of the world's fastest-growing area of research and development. Prosthetics is the study of prescribing, designing and fitting artificial replacements (may be any part of a normal human body) by biologically feasible materials, they may be internal (e.g., artificial body implants, internal knee joints used in knee joint replacement surgery, etc.) or external (artificial limbs, aesthetic fingers, etc.). One who is expert in this science is called as a prosthetist and mainly deals with the external replacements. A prosthetist deals with mainly amputees
Composition of the human body Not all elements which are found in the human body in trace quantities play a role in life. Some of these elements are thought to be simple bystander contaminants without function (examples: caesium, titanium), while many others are thought to be active toxics, depending on amount (cadmium, mercury, radioactives). The possible utility and toxicity of a few elements at levels normally found in the body (aluminium) is debated. Functions have been proposed for trace amounts of cadmium and lead, although these are almost certainly toxic in amounts very much larger than normally found in the body. There is evidence that
