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.
Lumbosacral transitional vertebrae consist of the process of the last lumbar vertebra fusing with the first sacral segment. [1] While only around 10 percent of adults have a spinal abnormality due to genetics, a sixth lumbar vertebra is one of the more common abnormalities. [2] Sacralization of the L5 vertebra is seen at the lower right of the ...
Interlaminar implant: This is a non-fusion U-shaped device that is placed between two bones in the lower back that maintains motion in the spine and keeps the spine stable after a lumbar decompressive surgery. The U-shaped device maintains height between the bones in the spine so nerves can exit freely and extend to lower extremities. [40]
Spina bifida (SB; / ˈ s p aɪ n ə ˈ b ɪ f ɪ d ə /; [9] Latin for 'split spine') [10] is a birth defect in which there is incomplete closing of the spine and the membranes around the spinal cord during early development in pregnancy. [1] There are three main types: spina bifida occulta, meningocele and myelomeningocele. [1]
The vast majority of spondylolysis occur in the lumbar vertebrae, however it can also be seen in cervical vertebrae. [2] 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 ...
Sagittal CT of the lumbar spine showing Baastrup's sign. The salient feature of the disorder is the exuberant osteophytosis that occurs at posterior lumbar spinous processes. Osteophytes are coarse calcifications at the edges of bone that form due to repetitive stress and trauma.
Persistent pain in the lower body, difficulties standing, walking, exercising or performing general tasks, discomfort during sleep, bowel or bladder dysfunction: Causes: Lumbar spinal stenosis, osteoarthritis, spondylosis, rheumatoid arthritis, Paget's disease, spinal tumor, herniated or ruptured disks, scoliosis, trauma, achondroplasia: Risk ...
The fifth lumbar vertebra is characterized by its body being much deeper in front than behind, which accords with the prominence of the sacrovertebral articulation; by the smaller size of its spinous process; by the wide interval between the inferior articular processes, and by the thickness of its transverse processes, which spring from the ...
