Nerve channel expansion surgeries are vital options for treating spinal problems and alleviating associated pain and weakness. Professor Dr. Yousry Anwar El-Hamili, a distinguished Professor of Neurosurgery and Spine Surgery at Cairo University Medical School, offers advanced surgical services aimed at improving patients’ quality of life and restoring their daily functions. His specialization in this field involves performing procedures that relieve nerve pressure, particularly in the spinal canal, and enhance the patient’s overall condition. Here are some details.
What Are Nerve Channel Expansion Surgeries?
The spinal canal, also known as the neural canal, runs through the vertebrae of the spine and houses the spinal cord, a central nervous system component. As the spinal cord travels through the canal, it branches into peripheral nerves that supply different parts of the body. However, age-related changes such as arthritis, joint enlargement, disc bulging, bone spurs, and ligament thickening can cause the neural canal to narrow. This narrowing can compress the spinal cord, leading to various troubling symptoms. Hence, many people opt for nerve channel or neural canal expansion surgery.
The surgery can be performed along the spine from the neck (cervical vertebrae) to the lower back (lumbar vertebrae). It involves making an incision in the back muscles and removing part of the lamina bone, a structure in the vertebrae that forms the roof of the spinal canal.
The surgeon removes the lamina and thickened ligaments to create more space for the nerves and remove bone spurs. The surgery may involve one or more vertebrae, depending on the extent of the narrowing.
Types of Nerve Channel Expansion Surgeries We Perform
There are several types of spinal canal expansion surgeries:
- Laminectomy: Removal of the entire lamina bone, part of the enlarged facet joints, and thickened ligaments covering the spinal cord and nerves.
- Laminotomy: Removal of a small part of the lamina bone and ligaments, usually on one side only, preserving the natural support of the lamina bone to reduce the risk of spinal instability.
- Foraminotomy: Removal of bone around the vertebral foramen – the canal through which nerve roots exit the spine. This method is used when disc degeneration narrows the spinal canal and compresses the nerve.
- Laminaplasty: Expansion of the spinal canal by cutting the lamina on one side and opening it like a door, used only in the neck (cervical region).
- Discectomy: Removal of part of a bulging disc to relieve nerve pressure.
In some cases, spinal fusion surgery may be performed simultaneously to stabilize the treated segments of the spine. Fusion uses bone grafts, screws, and rods to connect two vertebrae into one new bone, preventing future narrowing and alleviating pain from an unstable spine.
Indications for Spinal Canal Expansion Surgery
Indications for spinal canal expansion surgery include:
- Persistent leg or foot pain, weakness, or numbness indicating spinal canal narrowing.
- More severe leg pain compared to back pain, suggesting a spinal canal issue.
- Lack of symptom improvement after physical therapy or medication, necessitating surgery.
- Difficulty walking or standing due to pain or weakness affecting daily life.
- Diagnostic imaging (MRI, CT scan) showing spinal canal narrowing.
How Is Spinal Canal Expansion Surgery Performed at Our Center?
During spinal canal expansion surgery, the surgeon follows these steps:
- Patient Preparation:
- The patient lies on their back on the operating table and is anesthetized. After the patient falls asleep, they are turned onto their stomach with pillows supporting the chest and sides.
- The surgical area is sterilized and prepared.
- If spinal fusion is planned, the hip area is prepared for a bone graft.
- Making the Incision:
- An incision is made along the back over the targeted vertebrae.
- The back muscles are opened and moved aside to expose the lamina bone in each vertebra.
- Removing the Lamina or Part of It:
- The spinous process and lamina are removed using a drill or bone-cutting tools.
- The ligament connecting the lamina to the lower vertebra is removed.
- These steps are repeated for the targeted vertebrae.
- In some cases, the surgeon may prefer not to remove the entire lamina, making a small opening in the lamina above and below the spinal nerve root to relieve pressure.
- Relieving Spinal Cord Pressure:
- After removing the lamina and ligamentum flavum, the protective sheath of the spinal cord (dura mater) becomes visible.
- The surgeon gently moves the sheath and nerve roots aside to remove bone spurs and thickened ligaments.
- Relieving Spinal Nerve Pressure:
- The facet joint, directly above the nerve roots, may be trimmed to create more space for the nerve roots. This method, called foraminotomy, enlarges the neural canal where the spinal nerves exit the spinal canal. If a herniated disc causes pressure, the surgeon performs a discectomy.
Spinal Fusion
If there is spinal instability or multiple vertebrae are treated, spinal fusion may be performed. Fusion involves placing a bone graft secured with plates and screws to unite the vertebrae into a single solid bone. The surgical site is then closed, and the muscles and skin are stitched or stapled together.
Post-Surgery Care for Spinal Canal Expansion
Upon waking from surgery, the patient is taken to the recovery area, where vital functions such as blood pressure, heart rate, and breathing are monitored. Pain management is provided.
Once fully awake, the patient is moved to a regular room and gradually increases physical activity, such as sitting in a chair or walking slowly.
Here are some post-surgery tips and instructions typically given by Dr. Yousry and his team:
- Avoid bending or twisting the back to prevent pressure on the incision.
- Avoid lifting heavy objects to maintain incision integrity.
- Avoid strenuous activities like driving or heavy work until sufficient strength is regained.
- Avoid alcohol to prevent adverse interactions with medications.
- Apply ice to the incision area regularly to reduce pain and swelling.
- Change sitting or lying positions regularly to prevent muscle stiffness and adhesion.
- Take short walks regularly to promote circulation and healing.
- Take prescribed pain medications as directed, gradually reducing the dose as symptoms improve.
- Use stool softeners if pain medications cause constipation.
When to Contact the Doctor
Contact the doctor immediately if:
- There is a high fever.
- There is persistent vomiting or severe nausea.
- There are signs of infection at the incision site, such as severe redness or swelling.
- There is intense itching or a rash around the incision.
- There are new symptoms such as leg swelling and tenderness or new numbness and weakness in the limbs.
