Fractures of the neck of the phalanx of the finger are uncommon, but problematic, injuries in children. Displaced fractures may heal with malunion leading to loss of movement or angular deformity. Remodelling of the phalangeal neck is reported to be minimal because of the distance of the fracture from the physis. We report three displaced fractures in two children who presented late. The fractures were treated conservatively and remodelled completely. Both patients regained full movement of the fingers.

We examined prospectively 4719 newborn infants to determine the congenital incidence of trigger thumb. No cases were found.

Fifteen other children aged from 15 to 51 months had surgery for this condition. The anomaly had not been seen at birth and all thumbs presented with a flexion contracture without triggering. The condition is usually seen after birth as a flexion contracture of the interphalangeal joint. The term ‘congenital’ is a misnomer because patients acquire the deformity after birth. The term ‘trigger’ is inaccurate as most thumbs show a fixed-flexion contracture without triggering.

We suggest that rather than ‘congenital trigger thumb’ a more appropriate description of this disorder is ‘acquired thumb flexion contracture in children’. If the contracture persists after one year of age, treatment by dividing the A-1 pulley is simple and effective.
