Long Arm Casting for Treatment of Trigger Finger in Children: Report of Three Cases

Trigger digit in children is rare. Triggering predominantly occurs in thumbs presenting a flexion deformity of interphalangeal joint of finger. In children, the disease usually presents with a remained finger in locked flexion, unlike the adults in whom triggering is more prevalent. The pathology of the disease includes locking of the tendon over A1 pulley. Some treatment modalities have been suggested to cure the trigger thumb, such as conservative therapy without any invasive approach, and surgery. To the best of our knowledge, there is no report about casting as a treatment method for trigger finger in children. Herein, we report three cases of patients with trigger finger, who were treated by using long arm casting.
