[Treatment of metacarpal fractures].

Conservative treatment of metacarpal fractures is recommended if there is no joint displacement, malrotation, displacement of over 30 degrees ad axim and shortening of over 5 mm. Surgery should be performed in open fractures and serial fractures of metacarpal bone. Early functional treatment should be carried out in stable, not displaced fractures. A cast can be used for a short period in full extended position of fingers and flexion in metacarpo-phalangeal joint in 60 - 90 degrees. Twin-tape fixation allows functional treatment after soft-tissue swelling has disappeared. Closed reduction of displaced fractures of the fifth metacarpal bone (boxer's fracture) is not successful. Cases with displacement of over 30 degrees may be treated surgically by intramedullary stabilisation.
