Main ideas / concepts

What the carpal tunnel is

  • A narrow passage in the wrist.
  • Boundaries:
    • Wrist bones on the bottom and sides
    • A tough band of connective tissue on top: the transverse carpal ligament
  • Contents of the tunnel:
    • Muscle tendons
    • The median nerve

Role of the median nerve

  • Controls muscles in the palm and the base of the thumb, enabling movement.
  • Provides feeling/sensation to the thumb and nearby two and a half fingers.

Carpal tunnel syndrome (what it is)

  • A condition where tissue swelling increases pressure within the carpal tunnel.
  • This pressure compresses the median nerve.
  • Over time, median nerve compression leads to symptoms in the parts of the hand it supplies.

Common symptoms

  • Pain
  • Numbness
  • Tingling
  • Weakness

Risk factors

  • Smaller carpal tunnel, including:
    • Being female
    • Genetic factors passed down from parents
  • Wrist injuries
  • Other medical conditions that can cause inflammation, fluid buildup, or nerve damage, including:
    • Diabetes
    • Pregnancy
    • Rheumatoid arthritis
    • Obesity
    • Hypothyroidism
  • Repetitive hand or wrist motions

Treatment approach and methodology (as presented)

Mild to moderate carpal tunnel syndrome

  • Keep the wrist in a neutral position using:
    • a brace or splint
  • Consider medications:
    • NSAIDs (non-steroidal anti-inflammatory drugs) to help relieve pain

Moderate symptoms (doctor-directed)

  • Corticosteroid injection
    • Intended to reduce inflammation and swelling

Moderate to severe symptoms (doctor-directed)

  • Carpal tunnel release surgery
    • Two possible approaches:
      • Open procedure
        • Done via an incision between the palm and wrist
      • Endoscopic procedure
        • Done through a small keyhole incision
        • Uses an endoscope (tiny camera + surgical instruments)
    • Shared surgical step (both approaches):
      • Cut the transverse carpal ligament to relieve pressure on the median nerve
    • Closure:
      • Incision closed with sutures at the end of either procedure
