应用电测法研究了颅盖额、颞、枕部在局部应力作用下,其内、外板上的应力场之分布概况.应力从外板经板障传到内板后,主应力方向发生偏转,最大主应力和最小主应力也出现变化,表明应力场有了新的分布.本研究为临床上诊断和分析颅盖骨折的类型、部位及骨折线的方向等提供了生物力学依据. The distribution of the stress field on the inner and outer plates of forehead, temporal and occiput under the action of local stress was studied by electrical measurement method.After the stress transferred from the outer plate to the inner plate through the plate barrier, the principal stress direction The deflection, the maximum principal stress and the minimum principal stress also change, which indicates that there is a new distribution of stress field.This study provides a biomechanical basis for the diagnosis and analysis of the types, locations and fracture line directions of calvarial fractures in clinical practice.
