学龄前期儿童寰枢椎椎弓根形态特征发育的临床解剖学研究
Clinical anatomical study on the development of pedicle of atlantoaxial pedicle in preschool children
摘要
Abstract
Objective To discuss the characteristics,growth and development of atlantoaxial pedicle in preschool children,and to provide the basic theoretical basis for the design,production and clinical application of pedicle screw technique in the treatment of atlantoaxial disease in preschool children.Methods Excluded patients with atlantoaxial fractures,deformities,tuberculosis and tumor,the clinical data of 60 children aged from 3 to 6 years old with cervical spondylolisthesis were collected.The original CT images were reconstructed in DICOM format and the subjects were reconstructed with Mimics software.The subjects were grouped by age to measure and analyze the atlantoaxial pedicle correlation.Results The pedicle width(PW),pedicle height(PH) and total length of pedicle bone channel (PL) increased gradually with age.The PW/PH ratio of the vertebrae(C1) is greater than 1.0,and that is, the width of the pedicle of the C1 pedicle is greater than the height.The PW/PH ratio of the vertebral (C2) is less than 1.0,which means the width of the pedicle of the C1 pedicle is less than the height.Conclusion The growth and development of spine in preschool children are fast, and the pedicle of atlantoaxial calculus in different age groups has different developmental characteristics.In this study,the diameter of the pedicle of the atlantoaxial pedicle in the 3 to 6 year old children is increasing with age.The pedicle screw with the smallest diameter of 3.5 mm can be implanted into the atlantoaxial pedicle with feasibility in theory.关键词
