Carpal tunnel syndrome is one of the most common conditions affecting the hand and wrist. It occurs when the median nerve—which provides sensation to the thumb, index, middle, and part of the ring finger—becomes compressed as it passes through the carpal tunnel, a narrow passageway in the wrist.

When the space inside the tunnel becomes too tight, the nerve is irritated or “pinched,” leading to a range of symptoms that can interfere with work, hobbies, and daily activities.

Common Causes & Risk Factors

  • Repetitive hand or wrist motions (typing, assembly line work, gripping tools)
  • Wrist injuries such as fractures or sprains
  • Arthritis or joint inflammation
  • Fluid retention (often during pregnancy)
  • Medical conditions like diabetes or thyroid disease
  • Genetics—some people are born with a smaller carpal tunnel

Symptoms

Signs of carpal tunnel syndrome may start gradually and worsen over time:

  • Numbness or tingling in the thumb, index, middle, and part of the ring finger

  • Pain in the wrist or hand that may radiate up the arm

  • Weakness or clumsiness when gripping objects

  • Symptoms that worsen at night or with certain activities

Diagnosis

Our orthopedic team uses a combination of:

  • Physical exam – checking for numbness, weakness, or pain with certain movements

  • Nerve conduction studies – measuring how well electrical impulses travel along the median nerve

  • Ultrasound or EMG testing – evaluating the nerve and surrounding structures

Treatment Options

Many patients find relief with nonsurgical treatments, especially when symptoms are caught early:

  • Wearing a wrist splint at night

  • Reducing repetitive hand activities

  • Anti-inflammatory medications or steroid injections

  • Physical or occupational therapy

If symptoms persist or nerve compression is severe, carpal tunnel release surgery may be recommended to relieve pressure on the nerve and prevent further damage.
