Laminectomy: Definition
Laminectomy is a surgical procedure for treating spinal stenosis by relieving pressure on the spinal cord. The lamina of the vertebra is removed to widen the spinal canal and create more space for the spinal nerves. A Laminectomy is not recommended in people under 35 and should not be done on multiple adjoining levels, because it can destabilize the spinal column! (which, would require fusion and/or cages)

Some surgeons believe that the laminectomy procedure, by removing excessive amounts of bone and ligament from the spine, disturbs the biomechanical stability of the spinal column, resulting in pain. Alternative techniques for decompressing spinal nerves with minimal disruption of spinal stability have been developed and include microsurgical lumbar laminoplasty. (this is the procedure that Dr. Jho does)
Laminectomy: History
The first laminectomy was performed in 1887 by Dr. Victor Alexander Haden Horsley, a professor of surgery at the University College London.

A common type of laminectomy is performed to permit the removal or reshaping of a spinal disc as part of a lumbar discectomy. This is a treatment for a herniated disc, bulging or degenerated disc. Laminectomies are also used trim bone growth in the spinal canal, most noteably from the facet joint or to trim calcification of the spinal canal.

Laminectomy: Reasons for the Procedure
One of the most common reasons for laminectomy is a prolapsed or herniated intervertebral disc. If the herniated disc is in the lumbar region, this can cause sharp and continuing back pain, a weakening of the muscles in the leg, and some loss of sensation in the leg and foot. It may also be difficult to raise the leg when it is held in a straight position. A herniated disc in the neck region can cause symptoms including pain, numbness and weakness in the arm. A herniated disc may be triggered by, for example, twisting the back while lifting something heavy. The surgeon will attempt to relieve the pressure on nerves and nerve roots by removing the pulpy material that is protruding from the disc.



>>> Another website that may maybe of interest, they do microsurgical lumbar laminoplasty. They do a procedure that is very similar to Dr. Jho’s. Using the same Endoscopic tools from Johnson & Johnson. But they charge $60,000 and do not accept insurance >>>

At Laser Spine Institute (LSI) in Tampa, Florida, we use an arthroscopic approach to laminotomies to open up the spinal canal, without the need for general anesthesia, in an outpatient surgical setting. We do not perform laminectomies.A laminotomy is a surgical procedure that is used to relieve pressure off the spinal canal for the exiting nerve root and spinal cord, increasing the amount of space available for the neural tissue and thus releasing the nerve(s).
