Sequelae after a narrow lumbar canal operation: All you need to know

post-surgery recovery

An operation of narrow lumbar canal is a common procedure to relieve pressure on the spinal cord. This type of operation can be useful for treating different conditions. However, it is important to be aware of the potential sequelae (side effects) that follow this procedure.  

In this article, we will discuss the definition and anatomy of the operation of the narrow lumbar canal. We will mainly discuss the recovery period and the prognosis of patients who have undergone an operation of the narrow lumbar canal.

Lumbar Spine Anatomy

La lumbar spine is the lower part of the spine extending from the rib cage to the pelvis. It is composed of five vertebrae, each of which has a different form and function.

The first vertebrate, called the first lumbar vertebra (L1), is the largest and strongest in the lumbar spine. It supports the majority of the body's weight and is responsible for most spinal movements.

The second vertebra, called the second lumbar vertebra (L2), is slightly smaller than the first and offers less support to the body. However, it plays an important role in maintaining the stability of the spine.

The third, fourth and fifth vertebrae (L3-L5) are progressively smaller and offer decreasing levels of support. Together, these five vertebrae form a flexible yet strong structure that supports the body and allows for a wide range of motion.

What is a narrow lumbar canal?

The term " narrow lumbar canal » refers to a condition in which the diameter of the spinal canal in the lower back is narrowed. This narrowing can occur for a number of reasons, including osteoarthritis, injuries, and spinal deformities.

Although a narrow lumbar canal does not always cause symptoms, it can put pressure on the spinal cord or on the nerves that derive from it. This pressure can lead to pain, numbness, or weakness in the legs or lower back.

In severe cases, it can also lead to paralysis. The narrowing of the lumbar canal often occurs with age, due to wear and tear on the vertebrae. However, it can also be caused by traumatic injuries, tumors, or other spinal conditions.

Narrow spinal canal operation

La narrow spinal canal surgery is a type of intervention that involves widening the diameter of the lumbar canal. It is performed to relieve compression of the spinal cord or nerves, to reduce pressure and relieve symptoms.


The surgery of narrow lumbar canal is generally recommended for people who suffer from severe pain, numbness or weakness in the legs and who do not respond to conservative treatments.

It may also be recommended for people who have difficulty walking or standing due to pressure on the spinal cord. In some cases, surgery may be recommended to prevent paralysis.

Surgical techniques

There are several different techniques that can be used to widen the spinal canal. The type of surgery that is best for you depends on the severity of your condition and the anatomy of your spine

  • Discectomy: La discectomy is a minimally invasive surgical procedure to remove osteophytes from the narrow lumbar canal. It is performed through a small incision in the lower back and usually takes less than an hour. The surgeon removes the herniated disc which puts pressure on the nerve root, thereby relieving pain and restoring nerve function.
  • Decompressive laminectomy: this is the most common type of surgery narrow lumbar canal. It involves removing a small section of bone (lamina) from the vertebrae to create more space for the spinal cord or nerves.
  • Foraminotomy: this procedure involves widening the foramen, which is a small opening between the vertebrae through which nerves branch out from the spinal cord. This is done by removing bone or soft tissue.
  • Vertebral Fusion: In some cases, it may be necessary to fuse two or more vertebrae to stabilize the spine. This is done using rods, screws and/or metal plates to hold the vertebrae in place while they heal.

Your surgeon will discuss this with you and recommend the best approach for your particular case.


After the operation, you will be taken to a recovery room where you will be closely monitored. You will then be transferred to a hospital room where you will stay for several days.

During this time, you will receive pain medication and instructions on how to move and position yourself correctly to avoid unnecessary pressure on your spine. You will also be asked to perform some gentle exercises.

Once you are discharged from the hospital, you should continue these exercises at home. You will also need to take it easy for several weeks and avoid strenuous activities.

Full recovery after an operation can take several months. However, most people begin to feel better within a few weeks.

What are the sequelae following a narrow lumbar canal operation?

The most common side effect of breast surgery narrow lumbar canal is pain. This is usually taken care of with pain medication and should subside over time. Other sequelae can be the following:

  • Numbness or tingling in the legs or feet;
  • Weakness in the legs;
  • Difficulty walking or standing;
  • Muscle spasms ;
  • Difficulty urinating or having a bowel movement;
  • Infection ;
  • Bleeding;
  • Blood clots;
  • Reaction to anesthesia.

In most cases, these side effects are temporary and improve over time. However, if you experience persistent or severe symptoms, you should contact your doctor immediately.

Recovery and prognosis after surgery for narrow lumbar canal

After surgery of narrow lumbar canal, patients enter a recovery period during which they must be careful not to injure their spine again. The surgeon will provide specific instructions on activities to avoid during this time.

In general, patients should avoid any activity that causes back or leg pain. After the recovery period is over, patients can usually resume their normal activities.

The prognosis after the operation is good for most patients. However, some patients may experience persistent pain or nerve damage. In rare cases, surgery may not relieve symptoms and additional procedures may be needed.
