Medical titanium alloy bone nail is favored for its good biocompatibility and relatively soft properties. Titanium alloy is an inert metal with excellent compatibility with human tissues. It is not easy to cause rejection or infection after implantation. In addition, the elastic modulus of titanium alloy is similar to that of bones, which can better grow and fuse with surrounding bones and help the healing of fractures.
In contrast, stainless steel bone nails are known for their hardness, durability and low price. Stainless steel performs well in strength and hardness and is suitable for parts that require high mechanical support. However, the biocompatibility of stainless steel is slightly inferior to that of titanium alloy, and there may be a certain risk of rejection after implantation.
In terms of corrosion resistance, titanium alloy also shows obvious advantages. Medical titanium alloy bone nail can better resist corrosion in the body environment, extend its service life, and reduce the risk of implant failure caused by corrosion. Although stainless steel bone nails also have certain corrosion resistance, they may face corrosion problems in the long-term body environment.
The flexibility of medical titanium alloy bone nail is also a highlight. Titanium alloy has certain bending and not easy to break characteristics, which can better adapt to the physiological morphology of bones and reduce damage to surrounding tissues during implantation. Stainless steel bone nails are relatively rigid and may cause some compression to the surrounding tissues during implantation.
In terms of ease of operation, stainless steel bone nails are usually easier for doctors to operate and control due to their high hardness and rigidity. Medical titanium alloy bone nails require more delicate skills to operate due to their high softness.
The price of medical titanium alloy bone nails is usually higher than that of stainless steel bone nails. This is mainly due to the rarity of titanium alloy materials and the high processing cost. However, considering the advantages of medical titanium alloy bone nails in biocompatibility, corrosion resistance and flexibility, their prices are relatively reasonable.
Medical titanium alloy bone nails and stainless steel bone nails have their own advantages in performance. When choosing, doctors should weigh the specific conditions and needs of the patients and choose the implant material that best suits the patients.
