Lumbar Laminectomy is a kind of surgery often done to cure leg ache related to spinal stenosis, herniated discs, and other such problems. Stenosis happens as ligaments of the patient’s spine hardens and thickens, bulges in the discs, enlargement in the joints and bones, and osteophytes or bone spurs form. The stage of one vertebra slipping onto another vertebra (Spondylolisthesis) might also cause compression.
The objective of a Lumbar Laminectomy is to ease pressure on the spinal nerve or spinal cord by increasing the gap in the spinal canal. It is performed by trimming or removing the roof (lamina) of the vertebrae to generate more gaps for the nerves. A doctor might execute a Lumbar Laminectomy without or with combining vertebra or eliminating parts of a disc. Different devices such as, rods and screws might be used to improve the ability to get a firm fusion and hold unstable parts of the spine.
The spine of a human is usually from the head to the pelvis. The spine is made up of separate bones termed as vertebrae. These vertebras, stack on top of one other, and group up into four sections:
Posterior Lumbar Laminectomy helps to break down the nerve roots, and eventually help to lower extremity pain. While operating, the patient is firstly given anesthesia, so that the patient falls asleep, and then patient’s body will be turned to the prone position by use of cushions and gel rolls. After that the lower back will be cleaned, and then the surgeon will do the verticals.
Posterior Lumbar Laminectomy is a usually performed operation. The numbers of risks are generally less, but still they need to be kept in mind. These can be briefly explained in two levels.
- Operative risks, and
- The risk of anesthesia.
Firstly we’ll discuss the operative risks involved in Posterior Lumbar Laminectomy:
Surgical exposure: As the patient is being operated in prone position, there can be injured by pressure to nerves, eyes. Even muscular injury around spin can occur.
