ABSTRACT:
A device for dynamic external fixation of a distal fracture of the radius having a proximal leg fixed to the radius and a distal leg fixed to the metacarpal using fixation pins. The proximal and distal legs of the external fixator are connected by a hinge mechanism, which defines a range of flexion and extension of the wrist, and a track-track housing mechanism, which defines a range of radial and ulnar deviation of the wrist. The axis of movement of the hinge mechanism and the axis of movement of the track-track housing mechanism passes through the proximal pole of the capitate bone.
