Osteoarthritis in the basal joint of the thumb
Osteoarthritis is when the cartilage is loosening and its quality gets gradually worse and finally it disappears partly or completely. The defective cartilage causes an uneven load that makes the joint unstable. The basal joint of the thumb is particularly exposed to osteoarthritis especially among women over 40.
– Local pain in and around the joint.
– Motion pain may increase over the years, intense pain may appear.
– Resting pain. The basal joint may be swollen, warm and sore from contact and pressure. The opening grip decreases.
Heredity. An earlier injured joint may age/ grow old faster with osteoarthritis as result.
A firm splint or an elastic thumb brace. A night splint to counteract malposition. Ergonomic advice.
Daily training of active ROM without the brace. Injection of cortisone may relieve the pain effectively.
