Mark for Review What's This? Question 14 of 14 1.0 Points To design a hip joint replacement, would you use a stable inert material or a temporary biodegradable material? Count Characters

Explanation / Answer

13) Intimal hyperplasia is a process in which there become thickness of intima because of the presence of vascular smooth muscle cells also extracellular matrix rich in proteoglycan situated between the endothelium as well as the internal elastic lamina.The intimal hyperplasia formation is frequently linked with activation of vascular cell. Many factors result in the intimal hyperplasia formation like injury of vascular, aging and inflammation.12–16 Non-laminar shear stress, mainly at branch points in the vasculature, cause in a lenient form of intimal hyperplasia frequently mentioned to as intimal thickening. Marked elevation in blood pressure can cause intimal hyperplasia, like occurs in the the lungs small arteries in the adjustment of pulmonary hypertension.

14) Research for the biodegradable materials are needed to improve accomplishment of device, to upgrade function, transfer bioactive compounds and reach the aim of tissue regeneration. There are specially three types of biological implant materials: polymeric materials, metallic materials and ceramic materials. The alloying elements choosen in biodegradable alloy of Mg should be depend on the biocompatibility as well as betterment of mechanical properties. Metallic materials have a severe growth in the surgery of orthopedic destined for groeth of orthopedic devices, inclvolving permanent implants (overall joint replacement, hip prosthesis etc.) as well as temporary implants (pins, bone plates, etc.)
