title: Distal phalanx fracture in adults: Seymour-type fracture.
abstract: Seymour's fracture is an extra-articular, transverse, physeal, and juxta-epiphyseal open fracture of the distal phalanx seen in childhood. In this study, we present 10 adult cases of fractures localized to the metaphyseal region, 1-2 mm distal to the insertion of the extensor tendon. Mean age was 38 years. Four patients were treated conservatively with a mallet finger splint. Closed reduction and osteosynthesis with Kirschner wires (K-wires) was performed in three of the patients. Three of the patients had open fractures in whom closed reduction could not be performed. They underwent open reduction and osteosynthesis with K-wires. We recommend that extra-articular distal phalanx fractures mimicking mallet finger in adults are called Seymour-type fracture to establish a common language among clinicians to define this type of fracture. These fractures generally occur by hyperflexion of the distal phalanx and can be treated by conservative or surgical methods. The outcomes of conservative and surgical management of Seymour-type fractures depend on the appropriate reduction as well as efficient physical therapy.
