Degenerative spinal disorder

Disease Description (Causes and Symptoms)

Degenerative spinal disorder (= degenerative spinal disease) refers to a condition in which the intervertebral discs (discs), vertebral bodies, facet joints, ligaments, and other structures undergo degenerative changes with age, narrowing the spinal canal or neural foramina and compressing nerves, which causes symptoms. The main pathophysiological mechanisms include disc dehydration and herniation, facet joint hypertrophy and osteophyte formation, and ligament thickening (e.g., ossification of the posterior longitudinal ligament), which directly compress the spinal cord or nerve roots.
Main symptoms:

• Low back pain, neck pain, and joint stiffness
• Radiating pain (pain spreading to the buttocks, thighs, calves, or arms)
• Numbness, reduced sensation, and decreased muscle strength
• Neurogenic intermittent claudication, in which the legs feel pulled or become painful when walking, making it difficult to walk for long periods
• In severe cases, bladder or bowel dysfunction or inability to walk (requiring emergency surgery)

Calcification (ossification) of the posterior longitudinal ligament can cause the ligament to thicken and compress nerves, potentially causing numbness and paralysis in the hands and legs; in many cases, the cause has not been clearly identified.

Treatment Methods

1. Conservative treatment (early-stage or mild cases)

   • Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs), analgesics, gabapentin/pregabalin for neuropathic pain, muscle relaxants, etc.
   • Physical therapy and exercise therapy: Core-strengthening, extension exercises, and flexibility-improvement exercises. (Examples of recommended exercises: partial abdominal curls (a modified sit-up), knee-to-chest stretches, prone leg raises, and half prone upper-body lifts — stop if symptoms worsen.)
   • Injection therapy: Epidural steroid injections (for symptom relief)
   • Lifestyle management: Weight loss, smoking cessation, posture correction (avoiding prolonged sitting or bending the lower back), use of braces, etc.

2. Procedural and surgical treatment (indications: failure of conservative treatment, progressive neurological deficits, severe spinal canal stenosis, or instability)

   • Decompression: Posterior decompression (partial or total laminectomy), nerve root decompression
   • Fusion (when spinal instability is present): Fixation and fusion performed together with decompression
   • For specific lesions (such as ossification of the posterior longitudinal ligament), surgery involving an anterior or posterior approach or fusion is selected according to the location and extent of the lesion
   • Postoperative rehabilitation: Physical therapy to restore strength and flexibility, with gradual increases in activity

3. Prognosis

   • Varies depending on the symptoms and extent of the lesion. Most cases can improve with conservative treatment, but progressive neurological deficits (such as decreased muscle strength or bladder dysfunction) have better long-term outcomes with early surgery.

Precautions for This Disease

• Be careful because lifting heavy objects or suddenly bending or twisting the lower back can worsen the condition.
• If you are taking anticoagulants, be sure to consult your doctor before a procedure or surgery.
• Medication side effects (gastrointestinal NSAID side effects, drowsiness, dizziness, etc.) need to be monitored.
• If bladder or bowel dysfunction, rapidly progressing paralysis (a sudden major decrease in muscle strength), or severe movement impairment occurs, seek emergency medical care immediately.
• Smoking cessation, weight management, and regular strength and flexibility exercises are important for preventing recurrence.

Checklist Before an Outpatient Visit (Including Preparation Items and Example Questions)

Preparation items:

• Current medications (including prescriptions) and allergy information
• Previous test results and images (if possible, MRI/CT/X-ray films or CDs and radiology reports)
• Symptom diary (when symptoms began, factors that worsen or relieve them, changes in pain intensity, limitations in walking distance, etc.)
• Information about previous surgeries and chronic diseases (diabetes, hypertension, anticoagulant use, etc.)

Examples of items to mention or ask about during the consultation (things the doctor is likely to ask):

• When did the symptoms begin? Are they gradually worsening?
• Where does the pain or numbness spread? Does it change depending on walking or posture?
• Do you have muscle weakness, balance problems, or changes in urination or bowel movements?
• Have any treatments or medications helped relieve the pain?

Examples of General Questions to Ask the Doctor

• What is the cause of this disease, and what is the exact diagnosis in my case?
• What treatment options are recommended for my current symptoms? What are the advantages and disadvantages of each option?
• What are the expected effects and side effects of medication treatment?
• If surgery is necessary, what are the procedure, recovery period, and level of risk for complications?
• What should I be careful about in daily life (exercise, returning to work, driving, etc.)?

Examples of Disease-Specific Questions

• What is the degree of spinal canal stenosis on my MRI (or CT or X-ray), and is it likely to improve with conservative treatment?
• If ossification of the posterior longitudinal ligament is observed (or suspected by the doctor), is surgical decompression alone sufficient, or is fusion necessary? How can improvement of neurological symptoms after surgery be predicted?
