TMC Arthrosis - What's the Best Brace To Treat the Symptoms?

What is TMC Arthrosis?

Arthritis at the base of the thumb (formerly known as CMC Arthritis -now commonly referred to as trapeziometacarpal or TMC Arthrosis) is a common problem. In fact, TMC arthrosis has been found to be symptomatic in 26.2% of women and 13.2% of men age 71-100.

The symptoms of TMC arthrosis can negatively impact both functional and occupational performance, often making it necessary for the involvement of physical and occupational therapists. Recent surveys suggest that 87% of therapists recommend a splint to treat moderate TMC arthrosis and research literature suggests evidence to support use of a splint to decrease pain and improve function.

​Clinical Recommendations for Using a Splint for TMC Arthrosis

There have been numerous clinical studies on using a splint to treat TMC Arthrosis, but there is no evidence that shows one splint is better than another. Research evidence does suggest some clinical recommendations:

  • Splinting has been found to decrease pain and increase function for individuals with TMC arthrosis, (CMC joint arthritis).
  • Recommendations can be a client (patient) centered decision. Taking both the client’s preferences and therapist’s skills into consideration.
  • According to studies that examined client preferences- the prefabricated, neoprene-type designs using supportive materials with foam linings, may be preferred for wear during the day.
  • It is an appropriate conservative treatment option to trial wearing a splint during the day and functional use for 90-120 days.
  • Research has found long-term positive impact from using splints at night to minimize holding the thumb in stressful positions, so the recommendation of a night-time splint should also be considered.

The 3pp ThumSling supports the CMC joint and applies light compression to help reduce the slippage and grinding on the joint.
