Spinal disorder

Disease Description (Causes and Symptoms)

• Definition and pathophysiology: Spondylopathies refer collectively to a group of various diseases that occur in the spine (composed of 33 bones; 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, and fused sacral and coccygeal vertebrae) and its associated intervertebral discs, ligaments, joints, muscles, and nerves. Representative pathological conditions include degenerative disc disease (nerve compression caused by nucleus pulposus herniation or annulus fibrosus rupture), spinal canal stenosis, spinal infections (osteomyelitis and spinal cord abscess), inflammatory diseases (e.g., ankylosing spondylitis), trauma, and tumors.
• Main causes: Degenerative changes (age), repetitive mechanical stress, trauma, infection, inflammatory autoimmune diseases, tumors, and others. Disc lesions are common at the lumbar L4–5 and L5–S1 levels.
• Main symptoms: Low back pain, radiating pain (burning pain extending to the legs or arms), numbness/paresthesia, motor impairment (weakness and difficulty walking), autonomic symptoms (in severe cases, urinary or bowel dysfunction), and systemic symptoms (fever, weight loss, etc., in cases of infection or tumors). Symptoms vary depending on the location of the lesion (cervical, thoracic, or lumbar spine).
• Tests that aid diagnosis: Plain X-ray (structural and alignment abnormalities), MRI (excellent for evaluating intervertebral discs and nerve compression), CT (bony lesions), electromyography (evaluation of nerve conduction), myelography and radionuclide studies (in special circumstances), blood tests (markers of infection and inflammation), and others.

Treatment Methods

• Nonsurgical treatment (first-line in most cases):
  • Medication: Nonsteroidal anti-inflammatory drugs (NSAIDs), muscle relaxants, short-term oral steroids (selectively), gabapentin and pregabalin for neuropathic pain, and short-term opioids for severe pain (requiring caution).
  • Physical therapy and exercise: Strengthening the back and neck muscles, stretching, aerobic exercise (swimming, walking, and cycling), and posture correction.
  • Injections: Epidural steroid injections, nerve root blocks, and other treatments to relieve pain and reduce inflammation.
  • Lifestyle management: Weight control, smoking cessation (to inhibit degenerative progression), and proper working posture and use of braces.
• Surgical treatment (one or a combination of the following may be used):
  • Discectomy (microsurgical discectomy), facet joint decompression (decompression and laminectomy), spinal fusion (to correct instability or deformity), artificial disc replacement, and others.
  • Indications for surgery: Neurological deficits (progressive weakness), difficulty walking, irreversible bladder or bowel dysfunction (cauda equina indications), severe pain that does not improve with conservative treatment, and others.
• Risks of complications and precautions:
  • Complications: Chronic pain, permanent neurological deficits, postoperative infection, bleeding, nonunion (with fusion surgery), thrombosis, and others.
  • Precautions: Check whether anticoagulants are being taken, seek medical attention immediately if infection or fever is present, rehabilitation before and after surgery is important, and long-term smoking and obesity worsen the prognosis.
• Self-care tips:
  • Exercise regularly (strengthen the back muscles), use the legs rather than the back when lifting heavy objects, change position and stretch frequently when sitting for long periods, manage weight, and stop smoking.

Outpatient Visit Checkpoints (Including Preparations and Example Questions)

• Items/preparations:
  • List of currently taken medications (including prescription drugs, over-the-counter medications, and supplements)
  • Medical history: Previous back or neck surgery, trauma, history of infection or cancer, and whether immunosuppressants are being taken
  • Recent test results (if available, MRI/CT images or reports and X-rays)
  • Symptom diary: When the pain began, location and severity (pain scale), factors that trigger or relieve it, presence of sensory loss, weakness, urinary or bowel abnormalities, accompanying fever or weight loss, and others
  • Daily life and occupational information: Occupation (whether handling heavy objects), amount of exercise, and smoking status
• Acute warning signs that should be reported in advance during the outpatient visit:
  • Rapidly worsening weakness, severe weakness in both legs, loss of bladder or bowel control, progressive loss of sensation, high fever, and others (these symptoms require emergency evaluation).
• Regarding test preparation:
  • If an MRI is scheduled, check for metal objects or devices (such as a pacemaker); blood tests may be necessary.

Examples of General Questions to Ask the Doctor

• "What do you think is the cause of my symptoms? What additional tests are needed?"
• "What conservative treatment do you recommend, and how long might it take to see improvement?"
• "What are the main side effects of the medication you plan to administer, and what precautions should I take when taking it?"
• "If surgery is necessary, what is the prognosis, and what benefits and risks can I expect from the surgery?"
• "What activities should I particularly avoid in daily life, and what exercises are recommended?"

Examples of Condition-Specific Questions

• Regarding a disc (lumbar spine):
  • "According to the MRI findings, how much is the L4–5 disc herniation compressing the nerve root? How likely is it to improve with conservative treatment?"
• Regarding neurological symptoms (suspected cauda equina syndrome/paralysis):
  • "I have developed decreased urethral or rectal sensation or urinary dysfunction. Do I need emergency treatment right now? What are the criteria for going to the emergency room immediately?"
