When an implant is inserted, some biological reactions take place near the implanted area. This is the body's response to this newly implanted foreign material. A successful orthopedic implant promotes the adhesion of osteoblasts on the implant surface and the formation of new bone tissue, incorporating the implant into the body. However, if the body encapsulates the implant by the formation of soft fibrous tissue and tries to separate it as much as possible from surrounding bone, this is the sign of an unsuccessful implantation. The overall aim for numerous medical devices is to minimize the amount of fibrous tissue formation around the implant and to maximize appropriate new tissue growth.

Diabetes is a disease that affects the way your body uses food. Normally, your body converts sugars, starches and other foods into a form of sugar called glucose. Your body uses glucose for fuel. The cells receive the glucose through the bloodstream. They then use insulin a hormone made by the pancreas to absorb the glucose, convert it into energy, and either use it or store it for later use.
