The medical titanium alloys as a temporary matrix has a special induction effect on the growth of surrounding new tissue. In view of the common needs of a pedicle screw fixation system for surface mechanical properties and bioactivity of titanium alloy substrates, surface texturing and biological activity coatings show unique superiority on surface modification of titanium alloys. This paper intruduced the effects of surface texturing on the tribological properties and biocompatibility of titanium alloy, as well as the types of biological activity coatings. The improvement mechanism and limitations of texturing and bioactive coating on the surface properties of titanium alloy implants were also summarized. Finally, the problems and the development trend of the titanium alloys as biomedical materials were presented.
