The Study In Imaginativeanatomy Of Pre-nail Site Of Pedicle Screw And The Distance Change Of Thegreat Vessels In Front Of Lumbar With Bone Hyperpiasia Study Of Apoptosis Effects On HepG-2Induced By Codonopsis Lanceolata Extract

Objective:This article by lumbar leading edge hyperosteo geny pedicle screw pre nail parts of the front of the vascular distance measurement and hyperostosis distance, contrast, obs erve their changing patterns, as the leading edge of the lumba r vertebral bonestromal hyperplasia patients and pedicle screw into the safety warning of the fixed vertebral body in front of major vascular injury in the nail to provide a morphologica1basis. To reduce risk and increase the pedicle screw fixatio n strength, improve the safety of surgery.Methods:Select the complete three-dimensional CT data of40cases of lumbar the front hyperosteogeny patients (hyperpla sia) and40cases of lumbar spine leading edge of bone hyperpl asia patients (control group), to exclude structural abnormali ties of lumbar spine bone mineral and fracture cases. Each cas e L1-L5, lumbar pedicle screw pre-nail parts of the front of t he large vessels the distance measurements obtained pre-nail s ite and in front of the great vessels from the numeric values. The application packet for statistical analysis.Results:(1) L1, L2-L5bilateral pedicle screw pre-nail pa rts from the front of the great vessels from the proliferation group value was significantly greater than the control group, significant difference (P<0.05).(2) the right of the L1, L2-L4, bilateral pedicle nail pre-nail parts of the front diaphragm angle protection. The hyper plasia value is greater than the control group, a significant difference (P<0.05).(3) the longitudinal comparison of the L1-L5in the prolif eration and control groups of L1, L2, right side of the pedicl e screw pre-nail parts from the front of the great vessels fro m the values are greater than the left side of L4, the left si de of the pedicle screw pre-nail parts from the front of the g reat vessels from the value is greater than the right, a signi ficant difference (P<0.05). L3, L5, on both sides of similar value, is not very different.(P>0.05).(4) the right of the L1left, L4, L5bilateral pedicle scr ew pre-nail parts from the front of the great vessels from the proliferation group<4.0mm, the control group<6.3mm likely t o merge in front of vascular injury.Conclusions:(1) the leading edge of lumbar hyperplasia of bone anterior longitudinal ligament, diaphragm angle, large b lood vessels to the front of the pre-nail parts of the front o f the large blood vessels distance increases, the pedicle sere w breakthrough pre-nail parts of the cortical bone, compared w ithbone hyperplasia security.(2) normal adult developed the foot of the diaphragm is at tached to the front of the L1～L4, the diaphragm pin fusion o f the anterior longitudinal ligament, in front of large vessel s has a protective effect.(3) the right side of the L1, L2, gap than the left big br eakthrough of the pedicle screw pre-nail parts of the cortical bone, representing the left side of safety. L4left side of t he gap than the right side, the pedicle screw breakthrough pre-nail parts of the cortical bone, representing the right side of safety.(4) the right of the L1left, L4, L5bilateral pedicle scr ew pre-nail parts with the front of the blood vessels from the small, high risk of combined vascular injury.
