%X 在骨科中，与不可降解金属相比，镁合金作为可生物降解金属，可以在体内降解，达到在无需手术干预的情况下完全移除植入物，这减轻了患者的痛苦和经济负担。然而目前其腐蚀速率和机械性能方面存在缺陷，这可以通过合金化途径来得以改善。稀土元素作为合金化元素之一，由于其独特的化学和物理性质受到了越来越多的关注。因此，本文将以可降解稀土镁合金在骨科中的研究进展进行论述。<br />
Compared with non-degradable metals, magnesium alloys, as biodegradable metals, can be de-graded in vivo to achieve complete removal of implants without surgical intervention in orthopedics, which reduces the pain and financial burden of patients. However, there are defects in corrosion rate and mechanical properties, which can be improved by alloying. As one of alloying elements, rare earth elements have attracted more and more attention due to their unique chemical and physical properties. Therefore, this paper will discuss the research progress of degradable rare earth magnesium alloy in orthopedics.
