Displaced epiphyseal plate of the terminal phalanx in a child

A case of mallet finger in a child is described. The epiphysis of the terminal phalanx was displaced dorsally with the extensor tendon attached to it, and was first diagnosed two weeks after injury. The treatment was by open reduction. Radiograph three years later showed that a satisfactory position of the epiphysis and normal growth of the terminal phalanx had occurred.
