Rhizarthrosis/ Arthritic thumb

Rhizarthrosis is osteoarthritis of the base of the thumb. This pathology is very common in women over 50 years old. Genetic factors, menopause or the repetition of certain gestures seem to favour its appearance. Its evolution by seizures causes painful inflammatory attacks and gradually leads to stiffness and deformity of the thumb. It becomes gradually impossible to grasp an object between the thumb and forefinger or other fingers.
