Anatomy Of Lumbar Laminectomy

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:

1) 7 vertebrae (the neck which is cervical spine)

2) 12 vertebrae (the chest area which is thoracic spine)

3) 5 vertebrae (the lower part of the back or the lumbar spine)

4) The nonseparated vertebrae, 5 fused (pelvis area or sacrum)

The tailbone or the coccyx which is the spines base includes partly merged vertebrae which are movable.

The vertebrae are divided from one another with the help of pads that are very soft and are termed as “intervertebral discs”, they let the spine to flex and bend and perform as shock-absorbers at the time of normal activity. These intervertebral discs also stop the clashing of one vertebra with another. Each intervertebral disc comprises of two fractions, nucleus, which is a soft center and annulus which is an outer band and is tough.

Right through the spine is a tube at the centre, which is surrounded by discs and bone, this is the spinal canal. In the spinal canal there are spinal nerves, cauda equina, and spinal cord. From the base of the brain begins the spinal cord which ends as a bunch of nerves in the lumbar spine area termed as cauda equina. A couple of nerves in the spine that forms a branch which is at every vertebral point provide movement and sensation to all divisions of the body. A Lumbar Laminectomy might become necessary to ease pressure over the spinal canal.

All outcome and treatment results vary from individual to individual patients. Complications such as bladder and bowel problems, blood loss, blood clots, nerve damages and infections, together with issues relating to anesthesia, might be a few of the potential threats of Lumbar Laminectomy.

It is suggested to check with your doctor for a detailed list of warnings, indications, adverse effects, precautions, and other such crucial information related to medical grounds that are related to the Lumbar Laminectomy process.
