Carpal Tunnel Syndrome

Carpal Tunnel Syndrome

Carpal Tunnel Syndrome (CTS) is a condition that arises when the median nerve, which originates at the neck runs from the forearm into the palm of the hand, becomes compressed at the wrist.

What is the Carpal Tunnel?

The carpal tunnel is a narrow passageway made up of ligaments and bones at the base of the hand, the passageway allows for the median nerve and tendons of the wrist to travel through. When the tunnel becomes narrowed or the tissues surrounding the flexor tendons swell, it can compress the median nerve.

Causes of Carpal Tunnel Syndrome

1. Repetitive Hand Use

Engaging in repetitive motions of the hand and wrist, particularly those that involve prolonged flexing of the wrist, can contribute to the development of CTS. Common activities include typing, using a computer mouse and assembly line work.

2. Medical Conditions

Several medical conditions are associated with an increased risk of developing CTS, including:

  • Diabetes: Can cause nerve damage, including to the median nerve.
  • Thyroid Dysfunction: Hypothyroidism can lead to swelling in the carpal tunnel.
  • Pregnancy: Fluid retention during pregnancy can increase pressure within the carpal tunnel.

3. Trauma or Injury

Fractures, sprains, or other injuries to the wrist can alter the structure of the carpal tunnel and lead to compression of the median nerve.

Symptoms of Carpal Tunnel Syndrome

  • Paraesthesia (numbness, pins and needles): Often in the thumb, index, middle and ring fingers. This may be more noticeable throughout the night or when waking in the morning.
  • Weakness: Difficulty gripping objects, decreased strength in the hand, or a tendency to drop items.
  • Swelling: A sensation of swelling in the fingers, even if no visible swelling is present.
