    Patent number: 6530925
    Abstract: This fixator (1) comprises a rigid bar (7), two pin-holder assemblies (8, 9) which can be moved relative to this bar (7), and means (13, 22) with which it is possible to immobilize each pin-holder assembly (8, 9) in a defined position relative to the bar (7).
