摘要:

文题释义:
磷酸钙骨水泥:最早由美国的BROWN和CHOW于20世纪80年代提出,磷酸钙骨水泥是由一种或几种磷酸钙盐粉末的混合物与调和用的液相发生水化反应,在生理条件下能自固化。磷酸钙骨水泥在生理条件下发生水化反应得到与人体骨组织相近的固化产物——羟基磷灰石,具有一定的可降解性和良好的生物相容性。
改性:通过物理和化学手段改变材料物质形态或性质的方法。为了改进磷酸钙骨水泥在临床应用过程中遇到的机械性能差、降解速率慢、生物相容性低等问题,通过掺入不同性质的物质改善其物理化学性质。
背景:磷酸钙骨水泥具有良好的自固定性、易成型性,良好的生物相容性和骨传导性,是一种出色的骨移植材料,但其仍然有机械强度差、降解速率慢、生物相容性比较低等问题。
目的:探讨磷酸钙骨水泥改性相关的研究与临床应用。
方法:通过计算机检索Web of Science、PubMed、万方、中国知网,以“磷酸钙骨水泥、改性;Calcium phosphate bone cement、modification”为中、英文关键词,检索2014至2020年的文献。排除无关及重复文献,最终纳入72篇文献进行综述。
结果与结论:目前为止,磷酸钙骨水泥与生物活性物质、金属与非金属元素、有机物、干细胞以不同的方式混合可提高其机械强度、生物相容性、促进骨再生等,虽然通过在骨水泥添加不同物质可以改善其部分性状,但目前还处于实验阶段,制备的磷酸钙骨水泥还不理想。在临床应用过程中,磷酸钙骨水泥应用于骨折、骨髓炎及骨肿瘤的缺损修补相较于传统治疗方式具有较好的疗效,然而在应用过程中发生了新生骨生长速率及骨水泥降解速率缓慢、注射部位严重感染、填充物塌陷等并发症。

Abstract: BACKGROUND: Calcium phosphate bone cement has good self-fixation, easy formability, good biocompatibility, and bone conductivity, and is an excellent bone graft material. However, calcium phosphate cement still has the problems of poor mechanical strength, slow degradation rate, and low biocompatibility.
OBJECTIVE: To explore the research and clinical application of calcium phosphate cement modification.
METHODS: Web of Science, PubMed, Wanfang, and CNKI were searched using “calcium phosphate bone cement, modification” as English and Chinese keywords to search the relevant articles published from 2014 to 2020. Irrelevant and duplicate articles were excluded, and 72 articles that met the standard were finally included.
RESULTS AND CONCLUSION: To date, calcium phosphate cement and biologically active substances, metal and non-metal elements, organic matter, and stem cells have been mixed in different ways to improve their mechanical strength, biocompatibility, and promote bone regeneration. Although some properties of bone cement can be improved by adding different materials, it is still in the experimental stage, and the calcium phosphate cement is not ideal. In the clinical application of calcium phosphate cement, it has a better effect on repairing defects of fractures, osteomyelitis, and bone tumors than traditional treatment methods. However, complications such as slow growth rate of new bone and slow degradation of bone cement, severe infection at the injection site, and collapse of the filler occurred during the application.
