What happens to a broken thumb if not treated?

A broken thumb that is not treated properly can lead to a number of problems, including:

- Deformity: The thumb may not heal in the correct position, which can lead to a deformity. This can make it difficult to use the thumb for everyday activities, such as gripping objects and writing.

- Pain: A broken thumb can be very painful, and the pain may not go away completely even after the thumb has healed.

- Stiffness: The thumb may become stiff, making it difficult to move.

- Weakness: The thumb may become weak, making it difficult to grip objects.

- Arthritis: A broken thumb can increase the risk of developing arthritis in the thumb.

In some cases, a broken thumb that is not treated properly may require surgery to correct the deformity and improve function.
