The invention relates to an orthopedic external fixator apparatus for the treatment of diverse traumatic injuries and orthopedic pathologies of the hand, comprised of a pair of hemi-hexagonal skeletal-planes (1, 2), of which one is cephalic (1) and one is distal (2), containing several orifices (7, 10, 11) with corresponding transverse threaded (13a, 13b, 13c) orifices through which set screws (9a, 9b, 9c) secure surgical rods (8) within the skeletal-planes and both skeletal planes are connected to each other through a threaded orifice (3) by way of a pair Allen head threaded screws (4) fitted with retaining rings (5) such to allow the separation of the distal hemi-hexagon (2) when screws (4) are rotated.
