Pain in the metacarpophalangeal joint of the thumb

The thumb base joint is the joint between the first metacarpal bone and the first phalanx of the thumb. It should not be confused with the thumb saddle joint, which forms the transition from the carpus to the metacarpus. Pain in the metacarpo-phalangeal joint of the thumb may be caused by arthrosis, i.e. wear and tear of the cartilage surfaces.

As a rule, other joints of the hand are also affected by polyarthrosis. Women are particularly affected. Compared to other joints of the hand, especially the thumb saddle joint, arthrosis of the metacarpophalangeal joint is relatively rare. More likely is an injury to the joint capsule or the ligamentous apparatus of the joint. Typically, these are caused by sports injuries or by chronic overloading of the joint, as can occur with craftsmen.

Prophylaxis

A comprehensive prophylaxis against pain occurring in the thumb joint does not exist. It is important to correct malpositions of the joints at an early stage to prevent arthrosis at a young age. Large loads on the joints can also lead to arthrosis in the structures.

Since the thumb is often used in everyday life, it is also at risk of causing injuries. In general, activities or sports with typical thumb injuries can be avoided or performed with increased caution.
