Anatomy study of anterior blood vessels for bicortical lumbar pedicle screws fixation
摘要
Abstract
Objective To accumulate anatomy data for bicortical pedicle screw fixation technique and survey the anatomy relationship between the lumbar vertebra and great vessels in front of lumbar. Methods Three-dimensional computed tomography reconstruction of lumbar and abdominal vascular imaging was performed in 62 cases of adults (32 male, 17 female). The distances and spatial relation between lumbar vertebral anterior border and abdominal aorta, inferior vena cava, iliac artery were measured at the pedicle plane. Results At L1 ~ L4 pedicle planes, abdominal aorta was 0.26 ～0.37 cm from the left vertebral anterior border, and located in the area of -7° ～ 34° in front of vertebrae. At L1 ～ L3 pedicle planes, inferior vena cava was 1. 03 cm ,0. 75 cm ,0. 36 cm from the right vertebral anterior border respectively, and located in 17° -63° area. Lliac artery were less than0. 15 cm from the right anterior border of L4 both and anterior borders of L5 ,and located in 73°area. Conclusion In L1 ~ L4 ,it is quite possible to injury abdominal aorta if the left pedicle screws were over deeply planted. Screws planting in right pedicles of L1 ~ L3 is of a little risk of injuring inferior vena cava. When planting the screws in right pedicle of L4 both and pedicles of L5, it should be cautious of iliac artery.关键词
