Avulsion fractures from the base of the proximal phalanges of the fingers.

Thirty-three patients with avulsion fractures from the base of the proximal phalanges were treated during a 6-year period. All eight fractures treated conservatively failed to unite and subsequently required surgery. The remaining 25 patients were treated with primary internal fixation using a single lag screw through a palmar approach. Surgery gave excellent results in all cases and all patients achieved a full range of movement within 3 weeks.
