Laminectomy is generally used only when more-conservative treatments — such as medication, physical therapy or injections — have failed to relieve symptoms. Laminectomy may also be recommended if symptoms are severe or worsening dramatically.
Laminectomy is a medical procedure that generates room in the spine by extracting the lamina. The lamina is the rear side of the vertebra that protects the spinal canal. Otherwise called as decompression surgery, laminectomy expands the spinal canal to alleviate the harmful pressure on the spinal cord and nerves or nerve roots.
This medical procedure Is usually performed to alleviate the pain of stenosis. During laminectomy procedure the surgeon may treat one or multiple number of vertebrae.
This harmful pressure is mainly the result of the proliferation of bony overgrowths inside the spinal canal. These overgrowths are prevalent in patients with arthritis in their spinal cord.
Removing the Spinous
Initially, the surgeon cuts a little opening to access the spine. The spinous processes are the bony bumps or lumps that protrudes out from the back of the spine. The doctor carefully extracts the spinous process from the vertebra or vertebrae that requires medical care.
Removing the Lamina
Next step, the surgeon proceeds with the extraction of the lamina. This is that small portion of each vertebra that forms part of the back section of the spinal canal. Clearing away the lamina widens up the spinal canal, producing more room for the nerves. The surgeon may need to clear away the lamina from multiple vertebra to completely alleviate the pressure.
Removing the Bony Growths
The surgeon may also consider treating the foramina. These are the orifices positioned on each side of the vertebrae. This is where the nerve roots exits the spine. The physician inspects these holes and removes any spurs or bony growths that could harmfully press against the nerves or nerve roots.
End of Procedure
Surgical staples or sutures is used to close the incision made by the surgeon when the surgery is completed. The patient then stays in the recovery room for a few hours of monitoring before sending home with prescriptions. Physical therapy is also highly recommended to help heal the spine.
