In such a scenario, Entrepreneurship Development Institute (EDI) has developed a mechanism to render orthopedic implants rust-resistant. EDI has secured patent for the invention that promises to be a revolution in the healthcare sector.
Implant plates are made rustproof by chemicals, fixtures, electric current and voltage. The process has been invented by technocrats and scientists led by senior faculty K K Shaw of EDI's International Centre for Cluster Competitiveness, Growth and Technology. Senior orthopedic surgeon and joint replacement specialist Dr H P Bhalodiya says, "In India, we generally don't use pure titanium or stainless steel implants as they are overpriced. Since Indian doctors use half-price plates that are a mixture of various metals they corrode after coming in contact with internal environment. In most cases, rusting starts in less than one year."
"Rusting roughens metal surfaces and releases ions from the metal or alloy. This leads to toxic reactions and serious allergies. Studies show metal can cause the entire immune system to be suppressed. At times, small flakes of metals enter the bloodstream and soft tissues causing damage to DNA and increasing the risk of cancer," Dr Bhalodiya added.
Shaw says corrosion transmits contamination like iron particles, aluminum oxide, silicon carbide and various wax compositions on the surface generated by machining which is harmful to orthopedic implants.
"This invention eliminates the contamination of implants. The process is basically an electrolytic dissolution of metal chips and fine particles by applying direct current," he adds.
