摘要：

目的：对股骨假体置入后的生物力学进行探讨。
方法：应用计算机检索PubMed数据库及CNKI数据库，在标题和摘要中以“股骨假体，生物力学”或“Biomechanics，femoral prosthesis”为检索词进行检索。选择文章内容与股骨假体置入后的生物力学相关，同一领域文献则选择近期发表或发表在权威杂志文章，最终纳入26篇文献。
结果：目前常用的骨修复材料包括自体骨和金属假体。自体骨虽然是理想的骨缺损修复材料，但自体取骨增加了患者的创伤和痛苦，并且供骨的来源有限，难以满足大段骨移植的要求；金属假体对缺口敏感，存在松动、断裂、组织相容性差、不可降解等问题。
结论：骨科植入体大量应用解决了骨科学术领域的许多难题，研制理想的人工骨替代材料移植修复骨缺损，成为医学和组织工程学领域的研究重点。

Abstract:

OBJECTIVE: To explore biomechanics following femoral prosthesis implantation.
METHODS: A computer-based online search of PubMed and CNKI databases was performed with key words “biomechanics, femoral prosthesis” in English and Chinese. Articles related to biomechanics following femoral prosthesis implantation, published recently in authoritative journals of the same domain were selected. Finally, 26 articles were included.
RESULTS: Bone repair materials commonly used included autologous bone and metal prosthesis. Autologous bone is ideal repair materials, but bone acquisition increases trauma and pain for patients, and the source is greatly limited. Metal prosthesis is sensitive to wound, with some disadvantages, such as loosening, breakage, poor histocompatibility, and nondegradable.
CONCLUSION: Orthopedic implants application has resolved problems in orthopedic field. Ideal artificial bone substitutes for bone defects are important for medical and tissue engineering fields.
