The lumbar vertebra consist of a body, pedicle, lamina, pars interarticularis, transverse process, spinous process and superior and inferior articular facets, which form joints that link the vertebrae together. When examining the vertebra, the pars interarticularis is the bony segment between the superior and inferior articular facet joints ...
Bertolotti's syndrome is characterized by sacralization of the lowest lumbar vertebral body and lumbarization of the uppermost sacral segment. It involves a total or partial unilateral or bilateral fusion of the transverse process of the lowest lumbar vertebra to the sacrum, leading to the formation of a transitional 5th lumbar vertebra.
The pars interarticularis, or pars for short, is the part of a vertebra located between the inferior and superior articular processes of the facet joint. [1] [2] In the transverse plane, it lies between the lamina and pedicle. In other words, in the axial view, it is the bony mass between the facets that is anterior to the lamina and posterior ...
The lumbosacral ligament or lateral lumbosacral ligament is a ligament that helps to stabilise the lumbosacral joint.The ligament's medial attachment is at (the inferior border of) transverse process of lumbar vertebra L5; its lateral attachment is at the ala of sacrum.
Hakalo and Wronski (2008) showed the benefits of operative treatment such as using transoral C2-C3 discectomy with plate-cage stabilization or posterior direct pars screw repair for the reducing and healing process. [9] In deliberate or suicidal hanging, asphyxia is much more likely to be the cause of death due to associated prevertebral swelling.
Degenerative spondylolisthesis at L5-S1. (A) CT sagittal view of a low grade slip. (B) Lateral radiograph pre-operative intervention. (C) Surgically treated with L5–S1 decompression, instrumented fusion and placement of an interbody graft between L5 and S1. Both minimally invasive and open surgical techniques are used to treat anterolisthesis ...
Short ribs at the first lumbar vertebra, which is thus a transitional vertebra, since lumbar vertebrae normally do not have ribs attached to them. Transitional vertebrae have the characteristics of two types of vertebra. The condition usually involves the vertebral arch or transverse processes. It occurs at the cervicothoracic, thoracolumbar ...
The left crus arises from the corresponding parts of the upper two lumbar vertebrae only. The medial tendinous margins of the crura pass anteriorly and medialward, and meet in the middle line to form an arch across the front of the aorta known as the median arcuate ligament ; this arch is often poorly defined.
