چکیده
The increase in vertebral diseases has led to improvements in surgical operations and therefore implants. Due tothe sensitive nature of the spinal cord, the treatment in this region has significant medical concerns and theproperties of the implant used in this area are critical. It must have special mechanical and biologicalcharacteristics that are similar to those of bone. Nitinol is more suitable for orthopedic implants than otheralloys because of its features such as super-elasticity, close-to-bone elastic modulus, and also its goodbiocompatibility. In this study, a lumbar vertebral implant was manufactured by a two-step processing methodincluding sintering rod fabrication procedure and braiding technique and the effect of adding the braid to thestructure was evaluated. The applied Scanning Electron Microscopy showed an average pore size of ۳۱۰micrometers in samples. The results of Atomic Force Microscopy demonstrated that the average roughness is۹۷۱.۱ nm. The development of this type of implant aims to facilitate the treatment of vertebral areasکلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
