从生物力学角度观察了颅骨的胶原纤维分布及骨折断面的微观形态。骨折断面上有微骨折存在,主要沿骨板间走行,常绕过哈佛氏系统,表明骨板和哈佛氏系统均为重要力学单位。胶原纤维是骨板的框架,内,外环纤维及哈佛氏系统均在平行于骨表面的平面内多方向分布,使拱形的颅骨顶能承受更大外力。颅骨的夹层结构增强了对外力的缓冲作用,使其成为人脑天然有救的防护壳。本文还讨论了颅骨修补有关问题。

From the biomechanical point of view of the skull collagen fibers distribution and fracture section of the microscopic morphology. There are micro-fracture fractures exist, mainly along the plate walking, often bypassing the Harvard system, indicating that bone plate and Harvard system are important mechanical units. Collagen fibers are the framework of the bone plate. The inner and outer ring fibers and the Harvard system are distributed in multiple directions parallel to the plane of the bone surface so that the dome-shaped top of the skull can withstand greater external forces. The sandwich structure of the skull enhances the buffering effect on external forces, making it a natural protective shell for the human brain. This article also discusses cranial repair issues.
