An Irreducible Juxta-epiphyseal Fracture of the Proximal Phalanx

Abstract

The causes of irreducibility of juxta-epiphyseal fractures of the proximal phalanx are illustrated in a patient with button hole rent in the periosteum and extensor hood mechanism causing trapping of the distal fragment. The entrapment, in the manner of a Chinese finger trap, was aggravted by traction on the digit. Open reduction was necessary to reduce the fracture.
