What is Minimally Invasive Spine Surgery (MIS)?

Comprehensive Guide to Minimally Invasive Spine Surgery (MIS)

img

1.Definition

  • Minimally Invasive Spine Surgery (MIS) refers to advanced surgical techniques used to treat spine conditions with smaller incisions and reduced muscle disruption compared to traditional open spine surgery.
  • MIS uses specialized instruments, microscopes, and endoscopic cameras for precise and less traumatic procedures.

2. Purpose

  • Relieve chronic back or neck pain.
  • Correct spinal deformities or instability.
  • Treat conditions such as herniated discs, stenosis, and fractures.
  • Minimize tissue damage, reduce recovery time, and improve outcomes.

3. When is MIS Recommended?

  • Persistent back or neck pain unresponsive to conservative treatments.
  • Spinal compression causing neurological symptoms (numbness, weakness).
  • Degenerative disc disease, herniated discs, or spinal stenosis.
  • Fractures or tumors affecting the spine.

Types of Minimally Invasive Spine Surgery (MIS)

img
Microdiscectomy

Purpose: Treats herniated discs by removing part of the disc pressing on a nerve.

Procedure:

  • Small incision made.
  • Microscope or endoscope used for visualization.
  • Herniated disc portion removed, relieving nerve pressure.
img
Minimally Invasive Lumbar Decompression (MILD)

Purpose: Treats spinal stenosis by removing overgrown bone and tissue.

Procedure:

  • Small incision made.
  • X-ray guidance used.
  • Removal of tissue to relieve pressure on nerves.
img
Minimally Invasive Spinal Fusion

Purpose: Treats instability or deformity by fusing two or more vertebrae.

Procedure:

  • Incisions made on the back or side.
  • Bone graft or artificial disc inserted.
  • Screws or rods may be placed for stability.
img
Endoscopic Spine Surgery

Purpose: Treats herniated discs, stenosis, and fractures.

Procedure:

  • Tiny camera (endoscope) inserted.
  • Instruments used to remove or repair spinal tissue.
  • Performed through small incisions.
img
Laser Spine Surgery

Purpose: Treats nerve compression, herniated discs, or bone spurs.

Procedure:

  • Small incision made.
  • Laser technology used to remove or shrink tissue.
  • Minimizes trauma to surrounding structures.
img
Percutaneous Pedicle Screw Fixation

Purpose: Stabilizes the spine in cases of fracture or instability.

Procedure:

  • Small incision made.
  • Screws and rods inserted through percutaneous (skin) access points.
  • Minimizes muscle disruption.

Symptoms Indicating the Need for MIS

img
Chronic Back or Neck Pain

Persistent or severe pain radiating down the arms or legs.
Pain worsens with movement or prolonged activity.

img
Numbness or Tingling

Pins and needles sensation in the limbs.
Indicates nerve compression.

img
Muscle Weakness

Reduced strength or coordination in the arms or legs.
Difficulty walking or gripping objects.

img
Loss of Bladder or Bowel Control

Rare but severe symptom.
Could indicate cauda equina syndrome, a spinal emergency.

img
Sciatica or Radiculopathy

Pain radiating along the sciatic nerve (buttocks, legs).
Common symptom of disc herniation.

Risk Factors for Spinal Conditions Requiring MIS

Age and Degeneration

Older adults have a higher risk of degenerative disc disease and spinal stenosis.
May require MIS for pain relief.

Injury or Trauma

Falls, accidents, or sports injuries can damage the spine.
May lead to fractures or nerve compression.

Obesity

Increased weight puts strain on the spine.
Leads to faster disc degeneration.

Lifestyle Factors

Sedentary lifestyle and poor posture contribute to back issues.
May require surgical correction.

Hereditary Factors

Genetic predisposition to spine conditions.
Family history of disc disease or scoliosis.

Causes of Spinal Conditions Treated by MIS

Herniated or Bulging Discs
  • Occurs when the gel-like center of the disc leaks out.
  • Compresses nearby nerves.
Spinal Stenosis
  • Narrowing of the spinal canal.
  • Puts pressure on the spinal cord or nerves.
Spondylolisthesis
  • Slippage of one vertebra over another.
  • Causes instability and nerve compression.
Spinal Fractures
  • Trauma or osteoporosis can cause fractures.
  • May require MIS for stabilization.
Tumors or Infections
  • Spinal tumors or abscesses can compress nerves.
  • MIS may be performed for removal.

How to Prevent Spine Conditions Requiring MIS

img
Maintain a Healthy Weight

Reduces strain on the spine.
Lowers the risk of disc degeneration.

img
Exercise and Strengthen Core Muscles

Improves spinal support and flexibility.
Reduces the risk of injury.

img
Proper Posture

Avoid slouching or prolonged sitting.
Use ergonomic chairs and maintain spinal alignment.

img
Quit Smoking

Smoking reduces blood flow to the spine.
Slows healing and increases the risk of degeneration.

img
Avoid Heavy Lifting

Use proper lifting techniques.
Prevents sudden spinal injury.

Treatment Through Minimally Invasive Spine Surgery (MIS)

img
Pain Management

NSAIDs (ibuprofen) to reduce inflammation.
Muscle relaxants for muscle spasms.
Steroid injections for pain relief.

img
Physical Therapy

Improves mobility and strength post-surgery.
Enhances recovery and prevents future injury.

img
Bracing and Support

Spinal braces may be used post-surgery.
Provides stability during healing.

img
Surgical Intervention

MIS procedures to remove or stabilize damaged tissue or discs.
Reduces pressure on nerves.

Procedure Steps for Minimally Invasive Spine Surgery

img
Pre-Procedure Preparation

Imaging tests: MRI or CT scans to identify the issue.

Pre-surgical assessment: Blood tests and evaluation.

Anesthesia consultation: Local or general anesthesia.

img
Steps 1:

Small incision made (1-2 cm).

Endoscope or microscope inserted.

Steps 2:

Instruments used to remove or repair spinal tissue.

Spinal stabilization if necessary.

Steps 3:

Incision closed with stitches or staples.

Dressing applied.

img
Hospital Stay

Outpatient or 1-day hospital stay.

Pain management with medications.

Gradual Mobility

Walking encouraged shortly after surgery.

Avoid strenuous activities.

Medications

Painkillers and muscle relaxants.

Anti-inflammatory drugs.

Follow-Up Care

Physical therapy to regain strength.

Regular check-ups and imaging.
