Vertebral hemangiomas are observed throughout any age, although most are diagnosed in people within their 50s alongside a higher presence in females with a 1:1.5 male-to-female ratio. They often present in the vertebral body of the thoracic and lumbar spine with potential to extend into the posterior arch. They can involve a single or multiple ...
The lumbar vertebrae are located between the thoracic vertebrae and pelvis. They form the lower part of the back in humans, and the tail end of the back in quadrupeds. In humans, there are five lumbar vertebrae. The term is used to describe the anatomy of humans and quadrupeds, such as horses, pigs, or cattle.
The spinal column, also known as the vertebral column, spine or backbone, is the core part of the axial skeleton in vertebrate animals.The vertebral column is the defining and eponymous characteristic of the vertebrate endoskeleton, where the notochord (an elastic collagen-wrapped glycoprotein rod) found in all chordates has been replaced by a segmented series of mineralized irregular bones ...
The Charité, a mobile core device for use in the lumbar spine, was approved first, in 2004, but is no longer in use. prodisc, the longest continually used disc replacement device in the US, is a fixed core device manufactured by Centinel Spine and was approved in 2006 for the lumbar spine with a cervical device approved in 2007.
The intervertebral veins accompany the spinal nerves through the intervertebral foramina to drain the internal vertebral venous plexuses into the external vertebral venous plexuses. [1] They drain (in craniocaudal sequence) into vertebral vein, intercostal veins, lumbar veins, and lateral sacral veins. Upper posterior intercostal veins may ...
Congenital cervical spine stenosis commonly occurs due to short pedicles (that form the vertebral arch). When the spinal canal diameter divided by vertebral body diameter is less than 0.82, or the anteroposterior diameter of the spinal canal is less than 1.3cm or the distance between the pedicles is less than 2.3cm during imaging, cervical ...
The sacrum is curved upon itself and placed very obliquely, its base projecting forward and forming the prominent sacrovertebral angle when articulated with the last lumbar vertebra. It is also known as the "lumbosacral angle".
The superior transforaminal ligament attaches along the superior intervertebral notch (of the pedicle of the lower vertebra of the intervertebral foramen). [ 1 ] The mid-transforaminal ligament attaches at the posterolateral aspect of an annulus fibrosus at one end, and at the ligamentum flavum (posterior to the articular capsule of the ...
