About disc herniation
What is Disc Degeneration?
Disc degeneration refers to a chronic pain condition caused by damage to the internal structure of the intervertebral disc. This condition occurs when the disc, located between the vertebrae, experiences internal damage or degeneration without herniating outward. It is considered one of the main causes of lower back pain. Disc degeneration is related to the aging process or degenerative changes in the spine, particularly when the annulus fibrosus (A) is damaged, leading to increased pressure within the disc.
Structure and Function of the Disc
The intervertebral disc is a structure located between the vertebrae that absorbs shock and allows for flexibility in spinal movement. The disc consists of two main parts:
- Nucleus pulposus: Located at the center of the disc, this jelly-like substance serves to absorb shock.
- Annulus fibrosus: A tough fibrous tissue that surrounds the nucleus pulposus, protecting the disc from external impacts.
Disc degeneration primarily results from damage to the annulus fibrosus. Unlike herniated discs, which involve problems occurring externally, disc degeneration is characterized by issues arising internally. (A = Annulus fibrosus, B = Nucleus pulposus)
Causes of Disc Degeneration
Disc degeneration primarily occurs due to the following reasons:
- Aging: As people age, the discs naturally degenerate, losing their elasticity and becoming more susceptible to damage.
- Repetitive Stress: Lifting heavy objects repeatedly or applying continuous pressure on the back can lead to disc damage.
- Poor Posture: Sitting for long periods or working in awkward positions can increase the load on the discs, resulting in damage.
- Trauma: Injuries from accidents, falls, or other traumatic events can damage the discs.
Symptoms
The main symptom of disc degeneration is chronic lower back pain, which typically has the following characteristics:
- Localized Back Pain: Pain is primarily concentrated in the lower back, with radiating pain to the legs or buttocks being less common.
- Increased Pain When Sitting: Sitting or changing positions can exacerbate the pain.
- Pain When Bending Forward: Bending the back forward may intensify the pain.
- Persistent Pain: The pain generally lasts for several weeks and can sometimes continue for months.
Diagnosis
To diagnose disc degeneration, the following methods are employed:
- Medical History and Physical Examination: The doctor will listen to the patient's symptoms and check spinal movement and the location of the pain.
- Imaging Tests: MRI (Magnetic Resonance Imaging) scans can reveal the internal structure of the disc and identify any damage. A CT discography, which involves injecting dye into the disc, may also be used to identify the source of pain.
Treatment
Treatment for disc degeneration is divided into conservative and surgical approaches.
- Conservative Treatment:
- Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) or muscle relaxants may be used to alleviate pain.
- Physical Therapy: Includes posture correction, exercise therapy, and strengthening exercises to reduce the burden on the disc by strengthening surrounding muscles.
- Injection Therapy: Treatments such as nerve blocks or steroid injections may be used to reduce pain.
- Surgical Treatment:
- Endoscopic Discectomy: In cases of severe disc damage, surgery may involve removing or stabilizing the damaged disc using an endoscope.
- Artificial Disc Replacement: This involves replacing the damaged disc with an artificial one, but this surgery is only suitable under specific conditions.
Prevention
- Posture Correction: Maintaining proper posture while sitting and standing is essential.
- Exercise: Regular stretching and strengthening exercises for the back can help reduce stress on the discs.
- Weight Management: Maintaining a healthy weight is beneficial for spinal health.
- Proper Lifting Techniques: Instead of bending at the waist, it's better to bend at the knees when lifting heavy objects to reduce strain on the discs.
Disc degeneration can be managed effectively through appropriate treatment and care, helping to alleviate pain and improve quality of life..
