Lumbar laminectomy surgery aims to take away the majority of the lamina of a spinal bone or vertebra, which contributes to the lumbar spine (the portion of the spine, which constitutes the lower back). The lamina is the term given to the small section of bone, which arches over the root of a nerve.
Lumbar laminectomy surgery eventually becomes a necessity due to degenerative ageing of the spine. The ageing process results in the disc of connecting tissue, which sits in between the two spinal bones moving from its usual position. This disc of connective tissue is termed the intervertebral disc. The movement of this disc reduces the amount of vacant space between the two spinal bones. As this situation becomes increases in severity, spinal nerves and blood vessels can become trapped, resulting in extreme pain and reduced mobility. Lumbar surgery is commonly performed when back pain has unsuccessfully improved after receipt of more conventional therapeutics. If the condition remains untreated and if, over a considerable duration surgery is not undertaken by the patient, the nerve damage that will result will not be able to be reversed.
Lumbar laminectomy surgery is conducted with the objective of creating an internal environment, which increases the amount of available room for the spinal nerves and their connecting blood vessels, thereby allowing for their restoration. This need for restoration is especially important if the spinal nerves and blood vessels have been subject to compression. Lumbar surgery is usually carried out with the patient either under the influence of a general anesthetic or with the use of an epidural anesthetic. During the operation, the patient is arranged in a position appropriate for incision over the affected area. The procedure itself lasts approximately one or two hours in duration.
During the recovery process, patients are actively encouraged to quickly regain mobility with the aid of a physiotherapist. This prevents the development of blood clots and stiff joints following surgery. Prior to continuous betterment of both the patient’s pain control and their ability to move, discharge would be expected a few days subsequent to surgery. Complete physical recovery can be contemplated between six and twelve months following lumbar laminectomy surgery.
