Everything You Need To Know About Laminectomy Surgery 

Laminectomy is a surgical procedure that removes the lamina, which is the back section of the vertebrae that conceals the spinal canal. Laminectomy also called decompression surgery, expands the spinal canal to reduce the spine or nerves. Such stress is most often generated by bony overgrowths inside the spinal canal, which can emerge in spinal arthritis. The overgrowths are often referred to as bone spurs, and they’re a common side effect of aging in certain people.

Laminectomy surgery is often utilized primarily when other therapies, such as medicine, physiotherapy, or injections, have ceased to ease the pain. If the condition worsens or deteriorates rapidly, a laminectomy may be considered.

Goals Of Laminectomy

Compression of the thecal sac, spinal cord, spinal dura, and the cauda equina may result from lumbar spinal canal stenosis. When a few of these structures are crushed, neurogenic claudication (leg discomfort when moving or arching the spine backward) can occur, usually affecting both legs. By expanding the spinal canal, laminectomy surgery relieves compression on these nerve structures.

What Are The Risks Involved?

Laminectomy is a relatively safe operation. However, complications, as with any surgery, are possible. Complications that could arise include:

  • Bleeding
  • Infection
  • Clots in the blood
  • Nerve damage
  • Leakage of spinal fluid

Preparation for the surgery

You must abstain from eating and drinking for a particular period before the operation. Your doctor will be able to offer you precise guidelines on which medications you may and may not take before surgery.

Things To Expect

During The Surgery

Laminectomy is typically performed under general anesthetic, so you are motionless during the surgery.

Throughout the procedure, the surgical team checks your heartbeats, blood pressure, and oxygen levels. After you are asleep and unable to feel pain, the surgeon cuts in your back over the injured vertebrae and pulls the muscles away from the spine as necessary.

  • To eliminate the proper lamina, little instruments are employed. Based on the condition and mass index, the size of the cut may differ. Minimally invasive operations often employ smaller incisions than open procedures.
  • If a laminectomy is done as part of the surgical therapy for a herniated disc, the surgeon also eliminates the herniated section of the disc and any fragmented portions.
  • Spinal fusion could be required to stabilize your spine when one of the vertebrae has shifted to another or when you have a curved spine. During spinal fusion, the surgeon uses bone grafts and, when needed, metal rods and bolts to surgically fuse two or more of the vertebrae.

Post laminectomy

Following surgery, you are sent to a recovery room wherein a medical team monitors for issues related to the procedure and anaesthesia. You may be asked to move your arms and legs as well. Your doctor may prescribe pain relievers for the incision site.

You may be able to return home the same day as your operation, while some patients may require a brief hospital stay. After one laminectomy, your doctor may advise you to undergo physical therapy to increase your strength and endurance.

You may be able to resume work after a few weeks, based on the quantity of lifting, jogging, and sitting required for your profession. Your recovery period will be extended if you also undergo spinal fusion.

Result of the surgery

The majority of patients report measurable relief in their symptoms following laminectomy, especially a reduction in discomfort that spreads down the leg or arm. However, if you have a more severe form of arthritis, this advantage may diminish over time. Laminectomy is much less likely to relieve back discomfort.
