Degenerative Scoliosis: Understanding the Causes, Symptoms, and Treatment Options

What is Degenerative Scoliosis?

Scoliosis is a condition where the spine curves abnormally, typically in an S or C shape. For a curve to be classified as scoliosis, it must be at least 10 degrees more than what is considered normal. While scoliosis is often associated with children and adolescents, it can also develop in adults. This form, known as degenerative scoliosis, arises from the natural wear and tear on the spine's joints and discs over time. It is also referred to as adult-onset scoliosis or adult scoliosis. This condition most commonly affects the lower back (lumbar spine) and is typically diagnosed in individuals aged 65 and older.

The progression of spinal curvature in degenerative scoliosis can vary, but on average, it may increase by about 3 degrees per year. However, each person's experience is unique. The curvature itself is often minor, but it frequently coexists with spinal stenosis, a narrowing of the spinal canal. This narrowing can put pressure on spinal nerves, leading to pain in the back and legs.

Symptoms of Degenerative Scoliosis

The symptoms of degenerative scoliosis often develop gradually and can be linked to physical activity. Common signs include:

• Back pain: This is a hallmark symptom, often worsening with movement.
• Nerve pain: Pain may radiate from the back down to the feet, indicating nerve compression.
• Difficulty walking and balancing: Due to pain and potential nerve involvement, mobility can be affected.
• Leg pain: Similar to back pain, this can be caused by compressed nerves.
• Numbness or weakness in the legs: This is another sign of nerve compression.

Risk Factors for Degenerative Scoliosis

Several factors can increase an individual's risk of developing degenerative scoliosis:

• Age: The risk increases significantly with age, particularly after 65.
• Gender: Women are more prone to developing degenerative scoliosis than men.
• Osteoporosis: Weakened bones can contribute to spinal instability and curvature.
• Previous spinal injuries or surgeries: These can alter the spine's structure and increase wear and tear.
• Jobs involving heavy strain on the body: Certain occupations can accelerate spinal degeneration.
• Genetics: A family history of scoliosis may play a role.

Diagnosis of Degenerative Scoliosis

Diagnosing degenerative scoliosis typically involves a combination of a physical examination and medical imaging. During a physical exam, a doctor will assess your posture, range of motion, and check for tenderness. If degenerative scoliosis is suspected, the doctor will likely order imaging tests:

• X-rays: These are the primary tool for visualizing the spine and measuring the degree of curvature using the Cobb angle.
• MRI (Magnetic Resonance Imaging): An MRI provides detailed images of the soft tissues, including discs, nerves, and the spinal canal. It is particularly useful for identifying spinal stenosis and nerve compression.
• CT (Computed Tomography) scan: A CT scan can offer more detailed bone images and may be used in conjunction with an MRI.

The Cobb angle measurement on imaging is crucial for officially diagnosing scoliosis and determining its severity.

Treatment and Management of Degenerative Scoliosis

The primary goal of treatment for degenerative scoliosis is to manage pain and improve function. If there is no pain, treatment may not be necessary. When symptoms are present, options include:

Medications

Over-the-counter (OTC) and prescription pain relievers can help manage discomfort. These may include nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen, or stronger prescription pain medications. Spinal injections, such as epidural steroid injections, can also provide temporary relief from pain and inflammation.

Physical Therapy

A tailored physical therapy program can be highly beneficial. Therapists can guide you through exercises designed to strengthen core muscles, improve flexibility, and enhance posture. These exercises aim to support the spine and reduce stress on the affected areas. Therapists can also teach you techniques for pain management and safe movement.

Bracing

While less common in adults compared to children, bracing might be recommended in some cases. A brace can help support the spine and potentially slow the progression of the curve, especially if it is causing significant pain or functional limitations.

Surgery

Surgery is typically considered a last resort for degenerative scoliosis, reserved for cases with severe pain, significant functional impairment, or rapid progression of the curve that hasn't responded to conservative treatments. Surgical options may include:

• Decompression surgery: This procedure aims to relieve pressure on the spinal nerves, often by removing bone spurs or widening the spinal canal (laminectomy).
• Spinal fusion: This involves joining two or more vertebrae together to stabilize the spine and correct the curvature. This may be combined with decompression surgery.

It is essential to have a thorough discussion with your surgeon about the risks, benefits, and expected outcomes of any surgical procedure.

Alternative Therapies

Some individuals find relief from pain through complementary therapies such as acupuncture or chiropractic care. While these can help manage symptoms, they should not replace conventional medical treatment prescribed by your doctor.

When to Consult a Doctor

If you experience persistent back pain, leg pain, numbness, weakness, or difficulty with balance and walking, it is important to consult a doctor. Early diagnosis and appropriate management can help prevent the condition from worsening and improve your quality of life. Don't ignore symptoms that affect your daily activities or well-being.
