Basal Joint
Arthritis
 Definition:
The basal joint is formed by the first of the three thumb bones
and one of the wrist bones. Arthritis is a disease that slowly destroys
the joint by causing inflammation and stiffness to the joints. Arthritis
destroys cartilage covering the ends of the bones that acts like
a cushion and allows the bones to move smoothly. The bones then
rub against each other causing the joint to become inflamed.
Symptoms:
Common symptoms include pain, swelling, stiffness or deformity of
the thumb. Pain in the lower part of the thumb is most common and
can be increase by changes in the weather. Pain may also be experienced
when lifting an object, turning a door handle or unscrewing a jar
lid. Dropping is also a sign of basal joint arthritis.
Causes:
Wear and tear on the joint causes basal joint arthritis to occur.
A fracture or injury to the thumb increases your chance of basal
joint arthritis occurring at younger age.
Treatment:
Avoid activities in which you use your thumb and fingers to repeatedly
grip, twist or turn objects. Using a thumb splint will help alleviate
the symptoms associated with this condition.
