Abstract
A dorsally displaced epiphyseal fracture of the middle phalanx (Salter–Harris Type I) is described. The epiphyseal fragments were attached to the central slip of the extensor tendon and collateral ligaments. The articular surface of the PIP joint was intact and smooth. The epiphysis was reduced and fixed without cutting the central slip or the collateral ligaments 8 months after injury. This kind of fracture can occur in the PIP and DIP joints, and presents special diagnostic difficulties. Open reduction is evidently necessary to correct the displacement.
