Characteristic changes of sacral foramina in adolescents and its clinical significance / 局解手术学杂志

ABSTRACT

Objective To study the developmental patterns and aging characteristics of anterior sacral foramina and posterior sacral forami-na in adolescents aging from 12 to 18 years old through CT imaging scanning and three-dimensional reconstruction measurement,and to provide the anatomical basis for the diagnosis and treatment of sacral vertebra diseases.Methods The 30 adolescents without any the problems of nerv-ous system were selected to conduct 64-slice spiral CT in the pelvic cavity.The original data were input into three-dimensional reconstruction software Mimics with the form of DICOM,and the relevant indicators were measured and analyzed.Results There was no significant difference in the height,width and distance of inner edge of anterior sacral foramina and the posterior sacral foramina in different gender and sides (P >0.05).The physical development of human increases gradually with age and there were significant differences.Conclusion There is a regular change process in the relevant indicators of anterior sacral foramina and posterior sacral foramina in adolescents.But the clinical appli-cation must be combined with the results of individual imaging,the technology of reverse engineering and the support of rapid prototype manu-facturing so as to meet the satisfactory results of individualized treatment.
