The basal joint is located at the bottom of the thumb.  It allows the thumb to rotate and swivel.  It is also called the carpometacarpal joint.
Osteoarthritis often finds a home in the basal joint because we use our hands a lot.  Injury or trauma can lead to arthritis but so can overuse.  And who doesn’t overuse their thumbs?
Patients who experience CMC Arthritis or Basal Joint Arthritis will lose grip strength and have pain and sometimes swelling.  A thumb splint or thumb brace can help.
