Spondylosis: Causes, Diagnosis & Treatment

Spondylosis is a degenerative condition affecting the spine that becomes increasingly common with age. It involves the gradual breakdown of intervertebral discs, vertebrae, and facet joints, resulting in pain, stiffness, and limited mobility. This guide provides a comprehensive look at spondylosis from both medical and physiotherapeutic perspectives, including its causes, diagnostic methods, and treatment options.

What is Spondylosis?

Spondylosis refers to age-related degeneration in the spinal structures, including intervertebral discs, vertebrae, and facet joints. Often referred to as osteoarthritis of the spine, this degenerative process can occur in any spinal region—cervical (neck), thoracic (mid-back), or lumbar (lower back). Spondylosis may lead to bone spurs (osteophytes), disc herniation, and restricted mobility, impacting overall quality of life.

Causes of Spondylosis

The primary cause of spondylosis is the natural aging process. Over time, wear and tear lead to the breakdown of spinal components. However, several other factors contribute to its development:

1. Genetic Predisposition: A family history of spinal issues increases the likelihood of spondylosis.
2. Occupational Strain: Jobs involving heavy lifting, repetitive motion, or prolonged sitting contribute to spinal degeneration.
3. Previous Spinal Injuries: Past trauma to the spine can accelerate degenerative changes.
4. Obesity: Excess weight places additional stress on the spine, particularly in the lumbar region.
5. Sedentary Lifestyle: Inactivity weakens the muscles supporting the spine, contributing to earlier degeneration.

How is Spondylosis Diagnosed?

Early detection is crucial for effective management of spondylosis. Several diagnostic methods help identify this condition:

1. Clinical Examination: A physical exam may reveal signs of spondylosis, such as limited range of motion, muscle weakness, and abnormal spinal curvature.
2. Patient History: Recording symptoms like pain patterns, stiffness, and functional limitations aids in assessing the likelihood of spondylosis.
3. Posture Analysis: Observing posture can indicate underlying degenerative changes in the spine.

Radiological Testing for Spondylosis

Radiological imaging plays a vital role in confirming a spondylosis diagnosis. The following imaging tests are commonly used:

• X-Rays: X-rays can reveal bone spurs, disc space narrowing, and other degenerative changes in vertebrae.
• Magnetic Resonance Imaging (MRI): MRI provides detailed images of soft tissues, such as intervertebral discs and nerve roots, to identify disc herniation or spinal stenosis associated with spondylosis.
• Computed Tomography (CT) Scans: CT scans offer cross-sectional views of the spine, aiding in the detection of bone abnormalities and spinal canal narrowing.

Prevalence of Spondylosis with Age

Spondylosis is strongly correlated with aging, and its prevalence increases with age:

• Cervical Spondylosis: By age 60, over 85% of individuals show signs of cervical spondylosis, although not all experience symptoms.
• Lumbar Spondylosis: Approximately 50% of people over 40 show signs of lumbar spondylosis, with prevalence rising to nearly 90% by age 60.
• Gender Differences: While both men and women are affected, men may experience symptoms earlier and more severely.

Biomechanical Changes in Spondylosis

Spondylosis leads to several biomechanical alterations within the spine:

1. Loss of Disc Height: Degeneration of intervertebral discs results in reduced disc height, leading to closer spacing between vertebrae and potential nerve compression.
2. Facet Joint Changes: Wear and tear on facet joints cause them to enlarge (hypertrophy), contributing to stiffness and pain.
3. Osteophyte Formation: Bone spurs develop as the body’s response to stabilize the spine, but they can compress nerves, leading to pain and neurological symptoms.
4. Spinal Alignment Changes: Degeneration can cause abnormal spinal curvatures, such as kyphosis or scoliosis, exacerbating pain and functional limitations.

Treatment Options for Spondylosis

Treatment for spondylosis varies based on the severity and specific symptoms. Options include:

Conservative Management

1. Physical Therapy: A tailored exercise program can strengthen spinal-supporting muscles, improve flexibility, and alleviate pain.
2. Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs), muscle relaxants, and pain relievers can help manage pain and inflammation.
3. Injections: Corticosteroid injections may provide temporary relief from pain and inflammation in the affected area.
4. Manual Therapy: Techniques such as spinal mobilization and manipulation can improve mobility and reduce discomfort.
5. Lifestyle Modifications: Weight management, ergonomic adjustments, and regular physical activity are essential for managing symptoms and slowing progression.

Surgical Intervention

For severe cases where conservative treatments fail, surgery may be necessary to relieve nerve compression or stabilize the spine.

• Decompression Surgery: Removes bone spurs or other structures pressing on nerves.
• Spinal Fusion: Stabilizes affected segments to prevent further degeneration and alleviate pain.

Conclusion

Spondylosis is a common age-related condition that can significantly impact mobility and quality of life. Early detection and a comprehensive treatment approach—including physical therapy, lifestyle adjustments, and medical management—are essential for managing symptoms and preserving spinal health.
