There are several kinds of titanium alloys, namely industrial pure titanium, α -β titanium alloy and β titanium alloy.
2. Industrial pure titanium has good thermal properties and chemical stability, but its strength is low, so it is not suitable for fixing lumbar vertebrae.
3.α -β titanium alloy is one of the most widely used titanium alloys, which has high strength and corrosion resistance, but its hard texture may increase the risk of postoperative pain.
4.β titanium alloy has excellent elastic modulus and toughness, and is suitable for bone structure. However, the composition of β titanium alloy is messy and difficult to process, which leads to higher price.
5. Therefore, doctors need to comprehensively consider the characteristics of various titanium alloys according to the advantages and disadvantages of materials, surgical requirements and different parts of artificial limbs, and choose the most suitable titanium alloy as the material for lumbar fixation equipment for patients. So which titanium alloy is more suitable for artificial limbs should be the type recommended by doctors.
