Thumb arthritis



If you have :

– Pain at the base of the thumb (first and most common symptom)

– Zig-zag deformity of the thumb

– Difficulties to grip, grasp or pinch an object

you might have thumb arthritis (joint damage).


The condition is very common, mainly in women in their fifties. The cartilage that covers the joint bones deteriorates and then bones rub against each other, resulting in pain.

Medical options include:

  • Avoiding activities that cause pain
  • Splint support of the thumb and wrist (custom-made rigid splint for night, flexible neoprene for daily-use)
  • Anti-inflammatory drugs and pain killers
  • Steroid injection to improve the pain

Surgery can be recommended if you don’t respond to other treatments, within 6 months :

  • Trapeziectomy : removal of the damaged trapezium
  • Arthroplasty : the joint is removed and replaced by a prosthesis

Both surgeries offer effective pain relief. Thumb mobility is recovered within 3 to 6 months. Pinch strength remains limited in both cases.
