摘要：

背景：随着骨组织工程在临床骨科领域的发展，内固定植入后的稳定性一直是临床研究的重点，那么通过什么途径才能更好地掌握其置入后的生物力学变化呢？
目的：总结影像学在骨科植入物的应用级生物力学评估。
方法：应用计算机检索CNKI和Pubmed数据库中1999-01/2012-06关于影像学评估骨科植入物的文章，在标题和摘要中以“骨科，置入，钢板，螺钉，X射线、CT、MRI”或“orthopedics，implantation，steel plate，screw，X-ray，CT、MRI”为检索词进行检索。选择文章内容与骨科内固定植入物影像学评价有关者，同一领域文献则选择近期发表或发表在权威杂志文章。初检得到172篇文献，根据纳入标准选择关于骨科植入物影像学评价的25篇文献进行综述。
结果与结论：X射线平片、CT和MRI在骨科内固定置入后的评价有非常重要的作用，通过影像学途径可以掌握植入物置入后的位置、角度、植入材料与宿主的融合、自身的腐蚀等，评价植入物的生物力学稳定性和植入宿主后的生物相容性。X射线平片显示骨结构细节最好，MRI软组织、软骨对比最好，CT介于两者之间，X射线平片、CT、MRI各有优势，放射影响科和骨科医生了解各种检查的特点、利弊，结合患者的自身情况，选择合适检查方法，才更有利于把握置入后的疗效。

Abstract:

BACKGROUND: With the development of bone tissue engineering in clinical orthopedics, stability of internal fixation has been the focus of clinical research, then what are the means to a better grasp of the biomechanical changes after implantation?
OBJECTIVE: To summarize the biomechanical evaluation of the application-level imaging in orthopedic implants.
METHODS: The CNKI database and PubMed database (1999-01/2012-06) were used to search the related articles about radiographic evaluation of orthopedic implants. The key words of “orthopedics, implantation, steel plate, screw, X-ray, CT, MRI” in English and Chinese were put in the title and abstract for searching the articles. The articles that related to the radiographic evaluation of orthopedic implants were selected, and for the articles in the same field, those published recently or in the authorized journals were preferred. A total of 172 articles were obtained after the initial survey, and finally 25 articles were included for review according to the inclusion criteria.
RESULTS AND CONCLUSION: X-ray, CT and MRI in the evaluation after implantation of internal fixation play an important role, through the imaging pathway can grasp the location of the placement of the implants, angle, and the integration of implant materials with the host, as well as their corrosion, and it can evaluate the biomechanical stability of implants and the biocompatibility of implanted host. X-ray plain film shows the details of bone structure best, MRI is mainly used for detecting the soft tissue and cartilage, and CT can be used for representing the bone structure and detecting the soft tissue and cartilage both. X-ray plain film, CT and MRI have their advantages. Radiation and orthopedic doctors should understand the characteristics, pros and cons of various inspections, and combined with the circumstances of each patient to select the appropriate inspection methods which is more conducive to grasp the post-implantation efficacy.
