Biomedical metal materials have always been a major biomedical material with a large and wide range of clinical use due to their excellent properties such as high strength and toughness, fatigue resistance, easy forming, and corrosion resistance. They are also the preferred implant material for hard tissues (bones and teeth that need to withstand higher loads) and interventional stents. And nano-medical metal materials have better corrosion resistance and biocompatibility. This article focuses on the changes and improvements in the properties of several typical medical metal materials surfaces after nanocrystallization, and discusses the current problems and development prospects of nano-medical metal materials.
ObjectiveTo review the characteristics and applications of different implantation in cervical tuberculosis surgery and the research progress of the new implantation. MethodsBy consulting relevant domestic and foreign research literature on cervical tuberculosis, the classification, advantages, disadvantages, and prospects of implantations were analyzed and summarized. ResultsThe incidence of cervical tuberculosis has increased recently and has a high disability rate. Currently, the implantation in the surgical treatment of cervical tuberculosis are mainly divided into bone materials, metal materials, and bioactive materials; the above materials have their own advantages and disadvantages, for example, the amount of autologous bone is limited, the complications of allogeneic bone are common, and the bone fusion effect of metal materials is poor. With the development of science and technology, the implantation are also more diverse. ConclusionThe choice of the implantation affects the bone fusion directly, furthermore, it affects the effectiveness of cervical tuberculosis, the development of new implantation provides a variety of options for the treatment of cervical tuberculosis.
