【摘要】 目的：对股骨髁上、髁间骨折应用多功能股骨板（ＭＦＦＰ）内固定进行生物力学评价，比较不同内固定器械的优劣，为临床提供科学依据。方法：用１２具新鲜股骨髁进行电测实验应力分析，对多功能股骨板（ＭＦＦＰ）及其它不同内固定器械对照比较其生物力学性能。结果：证明多功能股骨板（ＭＦＦＰ）的生物力学性能优于加压滑动髁螺钉（ＤＣＳ）、Ｌ形钢板等其它内固定方式，其强度和刚度存在显著性差异（Ｐ＜０．０１），实验和理论分析结果得到髁间突上应力较大，股骨上应力趋于平缓，髁间分离位移较小。结论：多功能股骨板（ＭＦＦＰ）比其它内固定方式占有结构合理、生物性能好、防旋性能强、操作简便的优势。临床应用ＭＦＦＰ治疗股骨髁上髁间骨折１２例，优良率达９６．８％，均愈合、无并发症，表明ＭＦＦＰ是治疗股骨髁上髁间骨折较好的内固定方法，值得推广应用。更多还原

【Abstract】 Objectives: In order to provide the scientific base for clinical application of multi - function femoral plate(MFFP), we studied the MFFP system on supracodylar fracture and intercondylar fracture of femur and we compared the advantages and disadvantages of the different kinds of internal fixations to the MFFP system. Methods: Twelve femoral condyles of fresh cadaver were measured and analysed the biomechanical performances of the MFFP system and the other internal fixations. Results: The results show that the MFFP system is prior to dynamic condylar screw, L-steel plate and the other internal fixations, because the stress and the strength of the MFFP system is more different than the others. The experimental and theoretical results show that the stress of intercondylar process become bigger, the stress of femoral shaft become greater and the separate displacement of intercondyle become smaller. Conclusions: The MFFP system has following advantages. It has proper design, fitting humans biomechanical performances effctive ability on the anti-rotation and being easy to insert. The MFFP system was used on twelve supracodylar fracture and intercondylar fracture of femur. The result was shoued that the ratio escellent and good results was 96.8% and that all cases were cured and no complication. The result was showed that MFFP system oh supracodylar fracture and intercondylar fracture of femur was an excellent internal fixation. Therefore, it is worth popularizing.更多还原
