The Relationship Between Morphology of Lumbar Disc Herniation and MRI Changes in Adjacent Vertebral Bodies
Background: Intervertebral disc herniation has two common types, extrusion and protrusion, which may affect the adjacent vertebrae.In addition, it is associated with significant signal changes in T1 MRI (short TR/TE) and T2 MRI (long TR/TE). Methods: The present study is a cross-sectional analytic one, in which sampling was performed retrospectively. Cases were randomly selected from the pa...
متن کاملAnatomical Variations of Vertebral Artery
Introduction: Vertebral arteries arise from the root of the neck as the first branches from the superior-posterior aspect of the subclavian arteries. They ascend the neck to enter the cranial cavity and supply blood to the brain. Methods: A total of 20 cadavers (in 10 years) were dissected for the study of variations in the origin of the vertebral artery. This study was conducte...
متن کاملSurgical anatomic evaluation of the cervical pedicle and adjacent neural structures.
OBJECTIVE Although several clinical applications of transpedicular screw fixation in the cervical spine have been documented recently, few anatomic studies concerning the cervical pedicle are available. This study was designed to evaluate the anatomy and adjacent neural relationships of the middle and lower cervical pedicle (C3-C7). The main objective is to provide accurate information for tran...
متن کاملVariation in Lumbar Vertebral Pedicle Structure with Bone Mineral Density
Introduction: Despite widespread use of pedicles in lumbar spine fixation, relatively little is known regarding variations in pedicle structure particularly in osteoporosis. It is valuable to understand this relationship because pedicles provide an important area for screw fixation and a point of complication when screws penetrate through weak pedicle walls into adjacent structures. Hirano et a...
متن کاملAnalysis of risk factors for adjacent superior vertebral pedicle-induced facet joint violation during the minimally invasive surgery transforaminal lumbar interbody fusion: a retrospective study
BACKGROUND The purpose was to explore possible risk factors of facet joint violation induced by adjacent superior vertebral pedicle screw during the minimally invasive surgery transforaminal lumbar interbody fusion (MIS-TLIF). METHODS A total of 69 patients with lumbar degenerative disease, who underwent MIS-TLIF were retrospectively reviewed. Postoperative computed tomography images were use...
