Abstract:
The growth of cervicothoracic spine exhibits morphological quantitative changes,which is the support for the growth of whole spinal and thoracic cage.Research concerning regularity of longitudinal growth is conductive to understanding spinal pathological changes,especially for spinal deformity therapy.Techniques for thoracic vertebral pedicle fixation comprises Roy-Camilla,steffee,Dick,RF and Atlas Fixator (AF).Compared to other methods,AF is characterized by small trauma,strong axial bracing load,with satisfactory rectification results,which can avoid crankshaft phenomenon in a certain extent.In order to increase accuracy and safety of thoracic vertebral pedicle implantation,the implants positioning,imbedding method,as well as biomechanic characteristics were studied,and CT scanning was used as assistants.However,the thoracic vertebral pedicle implantation is unsatisfied to children,which may deprive partly of spinal growth capability or result in thoracic deformity.
