目的通过有限元分析研究不同空心螺钉内固定方式在Sanders Ⅱb.跟骨骨折的生物力学稳定性。方法在一名志愿者(男性,26岁,身高173 c.,体重70 kg)跟骨c.基础上,通过Mimic. 22.0、Geomagic.2.0、Solidworks2019、ANSYS workb.nc.2}2022等数字医学软件建立跟骨三维有限元模型,建立Sandres Ⅱb.跟骨骨折模型。螺钉分为以下3种:①纵螺钉:自跟骨结节向前部;②横螺钉:自跟骨外侧壁向载距突;③垂直螺钉:自跟骨底部向丘部,垂直于后关节面。螺钉配置方案如下:纵螺钉自跟骨结节上方、中部、下方为进钉点分为上方组、中部组、下方组,再依据双横螺钉+单垂直螺钉、单横螺钉+单垂直螺钉、双横螺钉+无垂直螺钉和单横螺钉+无垂直螺钉的配置方式进一步分为4个亚组,最终得到12个模型(a、b.c.d、e、f、g、h.i、j、k、l模型)。在后距关节面和中距关节面分别施加420 N和200 N载荷模拟成人单足站立时跟骨受力,分析各个模型的总形变位移,丘部、前部、关节面骨折裂缝相对位移,骨折断端、螺钉的应力峰值。结果i、j模型的总形变位移最低,k、l模型的形变位移最高;其余模型的最大形变位移变化幅度较小。丘部骨折裂缝平均相对位移在上方组最低(0.27 mm),下方组相对较高,其中k、l模型的变异最大;前部骨折裂缝平均相对位移在下方组最小(0.16 mm),其中i、k模型表现最佳;关节面骨折裂缝相对位移在所有模型中均保持在较低水平。上方组模型骨折断端平均应力峰值最低(60.20 MPa),中部组和下方组接近(分别为103.88 MPa和99.76 MPa)。上方组的螺钉平均应力峰值最小(222.77 MPa),下方组k、l模型的平均应力峰值最高,分别达到331.48、349.82 MPa。结论i模型(下置纵螺钉+双横螺钉+单垂直螺钉)在降低总形变位移和前部骨折裂缝相对位移方面具有优势,值得推荐。纵螺钉、垂直螺钉和横螺钉在跟骨骨折固定中承担着不同作用,医生可根据患者需求选择适宜的螺钉配置。

c.Sic.合材料作为一种高温结构材料,在航空航天热防护领域具有广泛的应用前景。然而,该材料的中低温抗氧化性能相对较差,制约了其在更广泛领域的应用。本研究采用料浆抽滤工艺,通过调节料浆中陶瓷含量在纤维增强体中引入不同含量的抗氧化组元b.,再通过反应熔体渗透法制备c.Sic.b.复合材料。系统研究了不同b.含量对复合材料结构组成及抗氧化行为的影响,并分析相关氧化机理。研究结果表明:引入b.颗粒显著降低了c.Sic.开口孔隙率,并明显提高了c.Sic.起始氧化温度。引入质量分数3%b.时,c.Sic.b.复合材料(b.样品)的抗氧化性能最优,其在900、1200和1500℃静态氧化1 h.质量损失率分别为0.009%、–0.301%、–0.596%,显著优于c.Sic.1500℃氧化后,b.样品的强度保持率最高,达到52%。900℃氧化时,c.Sic.b.复合材料主要经历c.和b.相的氧化,以O_(2)扩散反应控制的缓慢失重为主;1200℃氧化时,c.和b.相氧化速率加快,Sic.显著氧化,生成的b.(2)O_(3)、硼硅酸盐和SiO_(2)等氧化产物减缓了O_(2)的扩散速率,减小了基体碳的损伤;1500℃氧化时,Sic.化速率加快,生成的SiO_(2)在复合材料表面形成的连续氧化膜阻碍了O_(2)的向内扩散。b.(2)O_(3)、c.等气体产物溢出及持续生成SiO_(2)主导了整个氧化过程。
