What Is Spinal Stenosis?
Symptoms, Treatment and Surgery
Spinal stenosis is the progressive narrowing of the spinal canal in the lumbar or cervical region. This narrowing can compress neural structures and commonly causes leg pain while walking, numbness, and reduced walking tolerance.
Many patients describe it this way: "My legs start to hurt after I walk a short distance, and the pain eases when I stop and rest." This complaint is quite typical for spinal stenosis.
Symptoms of Spinal Stenosis
Symptoms vary by patient. Common findings include:
- Low back and leg pain that increases with walking
- Numbness, tingling in the legs
- Inability to stand for long periods of time
- Relief when leaning forward
- Urinary problems in advanced cases
Lumbar Degeneration and Spinal Stenosis
Yes. Lumbar degeneration is the most common cause of spinal stenosis. With age, the joints in the spine enlarge, the ligaments thicken and the canal narrows. This leads to compression of the nerves.
Who Is at Higher Risk for Spinal Stenosis?
Spinal stenosis is most common after age 50 due to cumulative degenerative changes in the spine. However, patients with a congenitally narrow canal may develop symptoms earlier.
In particular:
- Those who have worked in heavy labor for many years
- People who stand for prolonged periods
- Overweight people
- Those with a history of herniated discs
are at higher risk for symptomatic spinal stenosis.
Why Do Symptoms Worsen While Walking?
A common question from patients is: "Why does my pain increase when I walk and go away when I stop?"
When walking, the spine is in an upright position and pressure on the nerves in the narrowed canal increases. With rest or slight forward flexion, canal dimensions may improve and neural compression is reduced. This is why some patients feel better when leaning on a shopping cart.
This finding is quite typical for spinal stenosis.
Does Spinal Stenosis Progress?
Yes. If left untreated, spinal stenosis can gradually progress. Initially, there is pain only when walking, but over time:
- Pain at a shorter distance
- Constant numbness
- Loss of strength in the legs
may be seen. In advanced cases, problems with urinary or bowel control may arise. This requires urgent assessment.
Spinal Stenosis Treatment
Treatment is planned according to the severity of the patient's symptoms.
In mild cases:
- Medication
- Physical therapy
- Lifestyle adjustments
In advanced cases: spinal stenosis surgery may be considered.
Spinal Stenosis Surgery
Not every patient with spinal stenosis undergoes surgery. However, if pain is severe enough to prevent walking, symptoms are increasing, or urinary or bowel problems begin, surgical treatment may be necessary. Today, surgeries can often be performed with smaller incisions and a faster recovery process.
What Is the Difference Between Spinal Stenosis and Lumbar Disc Herniation?
These two conditions are often confused.
Lumbar disc herniation:
- Pain usually starts suddenly
- Pain radiates to one leg
- Increases with coughing, sneezing
In spinal stenosis:
- Pain gradually increases
- It can be in both legs
- Increases with walking, decreases with stopping
Sometimes these two conditions can occur at the same time.
Is Spinal Stenosis Surgery Difficult?
Although spinal stenosis surgery is often thought to be very difficult, advances in surgical techniques have made these operations safer today.
Objective:
- Removing pressure on the nerves
- Increasing the patient's walking distance
- Improving the quality of daily life
The decision to operate is individualized for each patient.
What Happens If I Do Not Have Spinal Stenosis Surgery?
Not every patient with spinal stenosis needs surgery. However:
- If unable to walk
- Daily life is severely affected
- If signs of nerve damage have started
surgery should not be delayed. Otherwise permanent nerve damage may develop.
What Should Patients With Spinal Stenosis Pay Attention To?
Patients diagnosed with spinal stenosis are usually given the following recommendations:
- Not standing for long periods of time
- Not carrying heavy loads
- Avoiding excess weight
- Doing the exercises recommended by the doctor
These measures may help control symptoms.
When should I be examined?
If any of the following conditions are present, evaluation should not be delayed:
- Significant pain and numbness in the legs when walking
- Loss of strength in the legs
- Night pain
- Change in urinary or toilet control
You can make an appointment for examination and evaluation.
Frequently Asked Questions
Spinal stenosis is the narrowing over time of the canal through which the spinal cord and nerves pass. The narrowed canal can compress the nerves and cause complaints such as back and leg pain, numbness and difficulty walking.
The most common symptoms are low back and/or leg pain that increases while walking, numbness and tingling in the legs, worsening while standing, and relief when bending forward. In advanced cases, loss of strength in the legs may occur.
When walking, the spine becomes more upright and pressure on the nerves in the narrowed canal may increase. Sitting or leaning forward can relatively widen the canal and allow the nerves to relax. Therefore, symptoms may decrease with rest.
Yes. Age-related degeneration can enlarge the spinal joints, thicken the ligaments and cause disc changes, all of which can contribute to narrowing of the canal.
A lumbar disc herniation more often causes sudden pain from disc pressure on a nerve, and the pain may radiate to one leg. Spinal stenosis usually progresses more slowly and is characterized by leg symptoms that increase with walking and decrease at rest. Some patients may have both conditions together.
Treatment is planned according to symptom severity. In mild to moderate cases, pain control, physical therapy, exercise and lifestyle adjustments can be applied. In advanced cases, surgical options to reduce pressure on the nerves can be evaluated.
Surgery may be considered when walking distance is significantly reduced, leg strength is progressively worsening, quality of life is severely affected, or urinary/bowel control problems occur. The decision is made individually according to examination and imaging findings.
Recovery time depends on the extent of surgery, the patient's age and accompanying diseases. Many patients have significant relief of leg complaints, but the process should be evaluated individually. Postoperative exercise and physical therapy recommendations are important.
In some patients, complaints may increase over time; walking distance may shorten, and numbness or loss of strength may become more obvious. If advanced symptoms are present, specialist evaluation is recommended without delay.
Rapid loss of strength in the legs, inability to urinate or urinary incontinence, new loss of bowel control, or rapidly increasing severe pain requires emergency evaluation.
