Reduction and stabilization of a distal radius-ulna fracture

1. Distal radius-ulna fracture.

2. Insert the most distal K wire and connect it with the ring.

3. Insert the most proximal K wire and connect  it with the ¾ ring.

4. Connect the rings by means of two
threaded rods with conical couple.

5. Distract the fracture acting on the nuts On
the threaded bars. If needed, add a third
threaded bar for reduction.

6. Perform the requested adjustments of
the axis sliding the bone along the K wires.

7. Perform the requested adjustment of
torsional deformities by rotating the rings.

8. Achieve a correct clinical alignment before any further stabilization.

9. Up to this point, the circular and hybrid
constructs are identical.
If you want to set a hybrid contruct up, connect a rail to the distal ring, on the cranio-medial side of the radius.

10. Insert a threaded pin in the radius,
connecting it to the proxi-mal slot.

11. Complete the stabilization as require.

Then, you have different options, based on the fracture’s features and your personal


Leave at least temporarily the proximal ring for further stability, adding a K wire to it. The
proximal ring may be removed after 3-4 weeks.

If you think the fracture is stable enough, remove the proximal ring and threaded bars, just
leaving the hybrid frame.
