Lumbar Laminectomy

laminectomy is the surgical removal of

part of the vertebral bone called the

lamina 24 vertebrae make up the

vertebral column or spinal column each

vertebra has two lamina fused together

to form the roof of the spinal canal the

lamina protect the spinal cord in the

neck and back regions in the lower back

where the spinal cord ends the lamina

protect the large bundle of nerve roots

called the cauda equina as well as the

nerve roots exiting the spine

nerve root compression can be caused by

bony Spurs from arthritis a herniated

disc compressing the nerve root or less

commonly a bony tumor of the vertebra a

laminectomy relieves back and leg pain

caused by this nerve root compression by

removing all or part of the lamina this

immediately alleviates the pressure on

the nerve root if a herniated disc is

present your doctor will often perform a

diskectomy which directly removes the

source of the compression a laminectomy

can be done on a vertebra in the lower

back called the lumbar vertebra or those

in the neck region called cervical

vertebrae micro laminectomy and micro

diskectomy our procedures performed with

the aid of a microscope when you arrive

at the hospital an intravenous line will

be started and the catheter may be

placed in your bladder to drain your

urine just before surgery you will be

given either general or spinal

anesthesia spinal anesthesia is injected

into a sac that surrounds your spinal

cord and numbs the area where the doctor

will be working with spinal anesthesia

you will be awake during the procedure

but you will have no feeling in the

lower half of your body a laminectomy

takes about one to three hours you will

lie on your stomach or on your side for

the duration of the procedure your

surgeon will begin by making a small

incision overlying your spine retractors

are used to pull fat and muscles away

from the lamina using a special bone

drill your surgeon will cut away the

lamina in order to see into the spinal

canal and locate the source of the nerve

compression if a herniated disc

is causing the compression he or she

will perform a diskectomy

by removing the protruding part of the

disc to complete the procedure the deep

tissues an incision in your back will be

closed with stitches

after your surgery you will be taken to

the recovery room for monitoring the

nursing staff will regularly check vital

signs and the strength of the leg on the

side of your surgery to be sure the

nerve has not been severely injured you

will be encouraged to get up and walk as

soon as you feel comfortable if a

catheter was inserted before your

surgery it will be removed before you

leave the hospital if you've had an

uncomplicated diskectomy you will likely

leave the hospital the next day

laminectomy is performed for other

reasons may require longer hospital
