What is degenerative disc disease?
Despite the name, degenerative disc disease is not a true disease; it is the natural aging of the spinal discs, accelerated in some patients more than others. As discs lose water content, height, and elasticity, they become less effective shock absorbers. For most people the changes are asymptomatic; in others they produce chronic mechanical pain and predispose to herniations, stenosis, and instability.
Anatomy
Disc degeneration begins in young adulthood and is progressive throughout life. Lumbar discs are most often affected because they bear the highest mechanical load. As a disc loses height, the surrounding facet joints take on more stress and develop arthritis themselves, which is why DDD frequently coexists with stenosis and spondylolisthesis.
What are the symptoms of degenerative disc disease?
- Chronic, dull, mechanical neck or low back pain
- Pain worsened by sitting, bending, lifting, or twisting
- Pain relieved by lying flat or changing position
- Periodic flare-ups of more severe pain
- Stiffness, especially after periods of inactivity
- Symptoms occasionally radiate into the shoulders, buttocks, or thighs
What causes degenerative disc disease?
- Natural aging of the discs
- Genetic predisposition
- Smoking: strongly associated with accelerated disc degeneration
- Obesity, which increases mechanical load
- Heavy occupational or athletic loading
- Prior injury
Who is at risk?
- Age: virtually universal by age 60 on imaging, though many remain asymptomatic
- Smoking and poor cardiovascular health
- Obesity
- Family history
- Heavy lifting or repetitive twisting occupations
How is degenerative disc disease diagnosed?
Diagnosis is made by combining symptom pattern with imaging. X-rays show disc-height loss and bone spurs; MRI is the most informative study, showing disc hydration, height, and any associated nerve compression. Discography is occasionally used in select cases to identify whether a specific disc is the pain generator.
When to see a spine surgeon
Consider evaluation when pain limits work, sleep, or daily activities for more than several months despite conservative care, or when new neurologic symptoms appear. Sudden severe pain, weakness, or bowel/bladder changes warrant urgent assessment.
How is degenerative disc disease treated without surgery?
Most patients improve with non-surgical care: physical therapy for core strengthening and aerobic conditioning, weight management, smoking cessation, NSAIDs, and image-guided injections (epidural steroid injections, medial branch blocks, or radiofrequency ablation when facet joints are the primary pain source).
When is surgery needed?
Surgery is reserved for refractory mechanical pain or for DDD that has produced significant herniation, stenosis, or instability. Options include cervical disc replacement (motion-preserving) and minimally invasive lumbar fusion (TLIF, ALIF, lateral, or endoscopic TLIF). The specific recommendation depends on the level affected, anatomy, and patient priorities.
Common questions
Is degenerative disc disease actually a disease?
No. Despite the name, it is the natural aging of the spinal discs, accelerated in some people more than others. Disc degeneration is virtually universal on imaging by age 60, and many people with degenerated discs have no symptoms at all.
Can degenerative disc disease be treated without surgery?
Most patients improve with non-surgical care: physical therapy for core strengthening and conditioning, weight management, smoking cessation, NSAIDs, and image-guided injections when a specific pain source is identified.
What makes disc degeneration worse?
Smoking is strongly associated with accelerated disc degeneration. Obesity and heavy occupational or athletic loading increase mechanical stress on the discs, and genetics play a meaningful role.
When is surgery considered for degenerative disc disease?
Surgery is reserved for refractory mechanical pain or for degeneration that has produced significant herniation, stenosis, or instability. Options include motion-preserving cervical disc replacement and minimally invasive lumbar fusion, matched to the level affected and the patient's anatomy and priorities.
Related procedures
Cervical Disc Replacement (CDR)
A motion-preserving alternative to fusion that replaces a damaged cervical disc with an artificial implant designed to mimic natural neck movement.
Anterior Lumbar Interbody Fusion (ALIF)
A two-stage spinal surgery that combines an anterior approach through a small abdominal incision with robotic-guided posterior pedicle screw fixation.
Lateral Lumbar Interbody Fusion (LLIF / XLIF / DLIF)
A minimally invasive spine surgery that reaches the damaged disc through a small incision on the side rather than through the back.
Lumbar Fusion (PLIF / TLIF)
Permanently joins two or more vertebrae in the lower back to eliminate painful motion and restore spinal stability.

Endoscopic treatment options
Many patients with degenerative disc disease can be treated through incisions of about 7 to 10 mm using endoscopic spine surgery. Dr. Kazarian performs the two-portal endoscopic technique, and explains how it compares with uniportal endoscopy. Whether an endoscopic approach fits your case depends on your imaging and symptoms; see the candidacy guide.
