  • Thumb locked in a bent position

You child may also have these symptoms:

  • Pain and swelling in their thumb, usually near the base
  • Bump on the palm side of their thumb, near the base

Trigger Thumb Diagnosis

Doctors can diagnose trigger thumb by asking about your child's symptoms and doing a physical exam.

If your child seems to have trigger thumb, the doctor will check to make sure they do not have some other problem, like a fractured bone or a joint that's out of place (dislocated).

The doctor will also check for signs of broader health conditions that may affect the hands, like cerebral palsy or arthrogryposis . (Most children with trigger thumb do not have any other condition.)
