Surgery is the only curative treatment and the results are very good.

Percutaneous release of congenital trigger thumbs/fingers patients under local anesthesia of 29 children of 38 fingers , 16 boys and 13 girls. 28 Thumbs , 7 middle fingers and 3 ring fingers. No case of indexes and little finger. The results are very good as shown in the photos.The results are good even being released at older ages.(12, 14, 25 and 44 year of age).anyway the deformities should be corrected by age of three before pre kindergartens to prevent manual skill developing in pre school period.
