Figure 1. Illustration of preparation process of the open-porous magnesium scaffold and in vivo animal model.

Step1: the 3D entangled titanium wire material (a,e) was prepared with Ti wires. Step2: the Ti-Mg composite (b,f) was prepared with high purity Mg melts. Step3: Ti wires were removed by HF solution and open-porous magnesium scaffold(c,g) was successful manufactured.Step4:open-porous magnesium scaffolds were implanted into the lateral epicondyle of rabbits(d).
