The Hand Patient: Trigger Thumb in Child

Abstract

RE: Your young patient with an inability to extend the interphalangeal (lP) loint of the right thumb. Thank you for the referral of your young patient, T T, a three-year-old right handed boy, who is unable to fully extend the lP joint of the right thumb. The mother maintains that she has noticed a difference between the left and right thumb since only recently when it became obvious that there was a difference in the flexion pattern of both thumbs. The child did not complain of any pain and has no other congenital abnormalities.
