The doctor will ask about your symptoms and health history. A physical exam will be done, paying close attention to the finger. You may be asked how the injury happened.

An x-ray may be done to check for a fracture.

Treatment

A splint will be needed to protect the finger as it heals. Other options are:

Medications

Medicine may be needed to ease pain and swelling. It may be given by mouth or with an injection.

Antibiotics may also be used to treat an infection.

Surgery

Some people may need surgery to repair the tendon. Exercises will also be given to help with finger strength and motion.

Prevention

This injury often happens due to accidents. There are no guidelines to prevent it.
