Title: Anatomic Relations of the Lumbar Pedicle to the Never
Abstract: Objective To investigate the anatomic relations of the thoracic pedicles to the spinal nerve roots.Methods Ten embalmed adult cadavers were obtained.All soft tissue were dissected,the spinous process from C7-L1,laminae,acets,and the transverse processes were removed.The superoinferior diameter of the nerve root and the frontal angle of the nerve root were measured.Also,Measurements were made from the pedicle to the nerve root superiorly and inferiorly.Results The average distance from the thoracic pedicle to the adjacent nerve roots superiorly or inferiorly ranged from 1.8~3.8mm and from 1.6~3.5mm.No epidural space could be found between the dural sac and the pedicle.The superoinferior diameter of the nerve root increased from 2.8 mm to 4.5 mm.Conclusion This study suggested that it be more dangerous in placing a screw penetrating medially than superoinferiorly.
