Lumbar laminectomy is the removal of the lamina or roof of the vertebra to provide enough space for the nerves to exit the spinal canal. A laminectomy is a surgical procedure that removes a portion of the vertebral bone called the lamina, which is the roof of the spinal canal. It is a major spine. Artrodesis vertebral posterior (lumbar). ¿Qué es? La artrodesis vertebral posterior (fusión intervertebral) es una cirugía para fusionar dos o más huesos de la.

A laminectomy is a surgical procedure that removes a portion of the vertebral bone called the laminawhich is the roof of the spinal canal. It is a major spine operation with residual scar tissue and may result in postlaminectomy syndrome.

Depending on the problem, smaller alternatives, e. The lamina is a posterior arch of the vertebral bone lying between the spinous process which juts out in the middle and the more lateral pedicles and the transverse processes of each vertebra.

The pair of laminae, along with the spinous process, make up the posterior wall of the bony spinal canal. Although the literal meaning of laminectomy is ‘excision of the lamina’, a conventional laminectomy in lamimectomia and orthopedics involves excision of the posterior spinal ligament and some or all of the spinous process. Removal of these structures with an open technique requires disconnecting the many muscles of the back attached to them.

A laminectomy performed as a minimal spinal surgery procedure is a tissue-preserving surgery that leaves more of the muscle intact and spares the spinal process. Another procedure, called the laminotomy, is the removal of a mid-portion of one lamina and may be done either with a conventional open technique or in a minimalistic fashion with the use of tubular retractors and endoscopes.

The reason for lamina removal is rarely, if ever, because the lamina itself is diseased; rather, it is done to break the continuity of the rigid ring of the spinal canal to allow the soft tissues within the laminecgomia to: A laminectpmia is also the name of a spinal operation that conventionally includes the removal of one or both lamina, as lumbat as other posterior supporting structures of the vertebral column, including ligaments and additional bone.


Lamknectomia actual bone removal may be carried out with a variety of surgical tools, including drills, rongeurs and lasers. The success rate of laminectoma laminectomy depends on the specific reason for the operation, as well as proper patient selection and the surgeon’s technical ability.

Laminectomia Lumbar

A laminectomy can treat severe spinal stenosis by relieving pressure on the spinal cord or nerve roots, provide access to a tumor or other mass lying in or around the spinal cord, or help in tailoring the laminectoomia of the vertebral column to correct a spinal deformity such as kyphosis.

A common type of laminectomy is performed to lamonectomia the removal or reshaping of a spinal disc as part of a lumbar discectomy.

This is a treatment for a herniatedbulging, or degenerated disc. The recovery period after a laminectomy depends on the specific operative technique, with minimally invasive procedures having significantly shorter recovery periods than open surgery.

Removal of substantial amounts of bone and tissue may require additional procedures such as spinal fusion to stabilize the spine and generally require a much longer recovery period than a simple laminectomy. With spinal fusion, the recovery time may be longer.

In some cases after laminectomy and spinal fusion, it may take several months to return to normal activities. Most commonly, a laminectomy is performed to treat spinal stenosis. Spinal stenosis is the single most common diagnosis that leads to spinal surgery, of which a laminectomy represents one laminectomai.

Laminectomy – Wikipedia

The lamina of the vertebra is removed or trimmed to widen the spinal canal and create more space for the spinal nerves and thecal sac.

Surgical treatment that includes a laminectomy is the most effective remedy for severe spinal stenosis; however, most cases of spinal stenosis are not severe enough to require surgery. When the disabling symptoms of spinal stenosis are primarily neurogenic claudication and the laminectomy is done without spinal fusion, there is generally a rapid lmubar and long term relief.

However, if the spinal column lumbqr unstable and fusion is required, the recovery period can last from several months to more than a year, and the likelihood of symptom relief is far less probable. In most known cases of lumbar and thoracic laminectomies, [5] [ dead link ] patients tend to recover slowly, with recurring pain or spinal stenosis persisting for up to 18 months after the procedure.


According to a World Health Organization census lkmbarmost patients who had undergone a lumbar laminectomy recovered normal function within one year of their operation.

Back surgery can relieve pressure on the spine, but it is not a cure-all for spinal stenosis. There may be considerable pain laminectomix after the operation, and pain may persist on a longer term basis.

For some people, recovery can take weeks or months and may require long-term occupational and physical therapy. Surgery does not stop the degenerative process and symptoms may reappear within several years. From Wikipedia, the free encyclopedia.
