第5颈椎椎弓根的显微形态学研究
Microstructure study of the 5th cervical vertebra with micro CT
摘要
Abstract
Objective To measure and analyze the microstructures of the 5th cervical vertebra with micro CT.Methods Micro CT scans were obtained from the 5th cervical vertebra of bone specimens of 5 adult cadaver who aged 45 to 57 years old.The scanned data were reconstructed with the Inveon Research Workplace.After being reconstructed with the Inveon Research Workplace,3 regions of interest(50×50×50,pixe3) were chosen in a coronalplane so that the results of bone volume/total volume(BV/TV,%),bone surface area/bone volume ratio(BS/BV,mm-1),bone surface(BS,mm),trabecular thickness(Tb.Th,mm),and trabecular number(TN,mm-1) were measured.The characteristics of the bone trabecular structure and the nutrient foramina were analyzed,and the thickness of bone cortex and medullary cavity diameter were measured.Results Trabecular microstructures were obtained after 3D reconstruction of micro CT scans of the 5th cervical vertebra.The lamellar-like trabecular bone make up a complex net-like micro-construction combined with rod-shaped trabecular bones in all direction.There was no significant difference in BT/TV,BS/BV,Tb.Th,TN compared with the regions of interest of the 5th cervical vertebra (P>0.05).The thickness of bone cortex and medullary cavity diameter between different parts of the 5th cervical vertebra were of statistically significant difference (P<0.05).And the nutrient foramina were discovered.Conclusion High-resolution 3D images of the 5th cervical vertebra can be obtained with micro CT as so to analyze not only the bone micro-structures but also the finite element and so on.关键词
