Embodiment Construction
[0034] The technical solution of the present invention is described in detail below through the examples, and the following examples are only exemplary and can only be used to explain and illustrate the technical solution of the present invention, rather than being interpreted as a limitation to the technical solution of the present invention.
[0035] like Figure 1 to Figure 5 As shown, in order to improve the degree of bone tissue immersion and bone healing speed, the high-strength zinc-manganese-magnesium alloy interface screw applied to the reconstruction and fixation of the anterior cruciate ligament claimed by the present invention is a hollow interface screw with side holes. According to CT Based on the results of three-dimensional reconstruction, combined with different heights, weights, ages and degrees of osteoporosis, a matching hollow interface screw with side holes was selected; the interface screw was made of high-strength low-alloyed Zn08Mn01Mg or Zn08Mn04Mg, an...
