Surgery to decompress the spinal nerves in the lower back is known as lumbar decompression. In addition to treating back pain, leg pain, numbness, and weakness, it can also treat spinal stenosis, herniated discs, and degenerative disc disease. By creating more space around the spinal nerves and reducing compression on the spinal cord, lumbar decompression alleviates these symptoms.
The following preparations may be necessary before lumbar decompression surgery:
Having a consultation with a spine surgeon is essential to discussing treatment options, evaluating the severity of the condition, and determining whether lumbar decompression is appropriate for you.
The extent of spinal compression may be assessed through imaging tests such as X-rays, MRIs, or CT scans.
An extensive medical evaluation will be conducted on patients to assess their overall health and identify any underlying medical conditions.
During the days leading up to surgery, patients may be instructed to adjust or discontinue certain medications, including blood thinners, NSAIDs, or herbal supplements, to reduce bleeding risks.
The lumbar decompression procedure typically involves the following steps:
During the surgery, the patient is placed under general anesthesia or spinal anesthesia to ensure they are comfortable and pain-free.
To access the affected area of the spine, the surgeon makes an incision in the lower back.
To relieve pressure on the spinal nerves, the surgeon may remove a portion of a lamina (laminectomy), thickened ligaments (ligamentum flavum), or herniated discs (discectomy).
In some cases, spinal fusion is performed simultaneously with lumbar decompression to stabilize the spine and prevent future instability by fusing two or more vertebrae together.
Decompression or fusion procedures are completed, the incision is closed with sutures or staples, and a sterile dressing is applied.
Recovery following lumbar decompression surgery may involve the following:
The patient may need to stay in the hospital for a few days following surgery in order to monitor their condition and manage their pain.
Patients are encouraged to gradually resume light activity and walking as tolerated, but strenuous activities should be avoided for several weeks.
Physiotherapy can help restore strength, flexibility, and range of motion in the back and legs.
Patients are encouraged to limit the use of narcotics and transition to over-the-counter pain relievers as soon as possible to reduce post-operative pain.
Although lumbar decompression surgery is generally considered safe and effective, certain risks and complications may occur, such as:
A surgical site infection may require antibiotics or additional treatment.
Blood transfusions may be required if there is excessive bleeding during or after surgery.
The surgery may cause nerve damage, resulting in weakness, numbness, or paralysis.
Developing a spinal fluid fistula or pseudomeningocele is caused by a tear in the dura mater (the membrane surrounding the spinal cord).
The following instructions may be given to patients after lumbar decompression surgery:
Following the surgeon's instructions for wound care and dressing changes, patients should keep their surgical incision clean and dry.
During the initial recovery period, patients should avoid lifting heavy objects, bending, or twisting the spine excessively to prevent strain or injury.
To monitor progress, evaluate healing, and address any concerns or complications, patients will be scheduled for follow-up appointments with their surgeon.
As a result, lumbar decompression surgery alleviates the symptoms of a variety of spinal conditions by relieving pressure on the spinal nerves. Patients can improve spinal health and function after lumbar decompression surgery if they understand the preparation, procedure, recovery process, risks, and aftercare instructions.
