Lumbar Laminectomy
Laminectomy is an operation performed in order to remove portions of the vertebral bone called lamina. The objective of this removal is to relieve pressure off the lamina. A degeneration in this part of the spinal tract results in spinal stenosis, herniated disc and other related conditions.
The Human Spine
The human spine is a long chain bones called vertebrates. These bones are placed one on top of another, separated by soft pads called intervertebral discs, resulting in a chain like formation which then supports the rest of our body parts. This chain is called the spinal column and is divided into 4 regions (listed in ascending order)-
* Cervical spine (supports neck)
* Thoracic spine (supports the chest area)
* Lumbar spine (supports low back)
* Sacrum (supports pelvis area)
Through this spinal column runs a tube called the spinal canal. It houses the spinal chord and a bundle of nerves called cauda equine. The whole canal is sensitive to pressure and is, hence, protected by a column of bones.
Lower Back Pain and Lumbar Spine
The lumbar spine supports the lower back. Any problem in the lumbar spine then results in lower back of varying intensity. The underlying cause of lower back pain is usually a herniated disc. However, other reasons may also include the following:
* Tumours
* A disc fragment (this will often cause more severe symptoms)
* Protruding/degenerating discs
* An osteophyte or bone spur (a rough protrusion of bone)
* Facet arthritis and/or cysts
