【摘要】：采用有限元方法模擬研究了高氮無鎳不銹鋼接骨板厚度減薄對其力學行為的影響規(guī)律。結(jié)果表明,接骨板厚度減薄18%以內(nèi),其抗彎能力、抗拉能力和抗壓能力均優(yōu)于傳統(tǒng)尺寸的316L不銹鋼接骨板。通過12周動物骨折模型研究了輕量化高氮無鎳不銹鋼骨板對骨折愈合后的生物力學的影響。結(jié)果表明,厚度減薄約14%的高氮無鎳不銹鋼接骨板固定兔子骨折股骨更有利于骨折的愈合和恢復。
[Abstract]:The effect of thickness reduction on mechanical behavior of high nitrogen nickel free stainless steel plate was simulated by finite element method. The results show that when the thickness of the plate is reduced by less than 18%, the flexural, tensile and compressive capacity of the plate is better than that of the conventional 316L stainless steel plate. The effect of lightweight high nitrogen nickel free stainless steel bone plate on biomechanics after fracture healing was studied in a 12 week animal fracture model. The results showed that the thickness reduction of about 14% of the high nitrogen nickel free stainless steel plate fixation of the fracture of rabbit femur is more conducive to the healing and recovery of the fracture.
