Basal Thumb Joint (Carpometacarpal Joint)
Degenerative or inflammatory arthritis of the thumb carpometacarpal joint. This is a very common condition and presents with radial hand or wrist pain and loss of grip strength. Failure of conservative methods is an indication for injection therapy. Other small joints in the hand can be injected in a similar way. These joints are small and may be difficult to access, particularly where degeneration is severe.
