The trapezium is one of your wrist bones that lie at the base of your thumb. Arthritis in this joint is common. It is a progressive condition and can lead to pain, stiffness and deformity of your thumb.
Initially you may be treated with splints and activity modification but may need injections or surgery if this does not improve.
Splints can be fashioned from either soft neoprene or hard thermoplastic and worn at certain times of the day or night.
A qualified Hand Therapist can advise on joint protection, activity modification and energy conservation.
Steroid with local anaesthetic is injected into the joint. You will then be reviewed in a few weeks to assess the response to treatment. The Steroid injection can certainly help with the pain of thumb based arthritis.
