Lumbar Laminectomy
Laminectomy is a spine operation to remove the portion of the vertebral bone called the lamina. There are many variations of laminectomy, in the most minimal form small skin incisions are made, back muscles are pushed aside rather than cut, and the parts of the vertebra adjacent to the lamina are left intact. The traditional form of laminectomy (conventional laminectomy) excises much more than just the lamina, the entire posterior backbone is removed, along with overlying ligaments and muscles. The usual recovery period is very different depending on which type of laminectomy has been performed: days in the minimal procedure, and weeks to months with conventional open surgery.
As pictured, the lamina is a posterior arch of the vertebral bone lying between the spinous process, which juts out in the midline, and the more lateral pedicles and 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, the operation called conventional laminectomy, which is a standard spine procedure in neurosurgery and orthopedics, removes the lamina, spinous process and overlying connective tissues and ligaments, cutting through the muscles that overlie these structures. Minimal surgery laminectomy is a tissue preserving surgery that leaves the muscles intact, spares the spinal process and takes only one or both lamina. Laminotomy is removal of a mid-portion of one lamina and may be done either with a conventional open technique, or in a minimal fashion with the use of tubular retractors and endoscopes.

Good to have a proper understanding of the disease from the inside.There is a need to know about a disease when you or your loved one is struck with one.It helps to get treated and the medication is received better by the body.
