Proximal  Block is made with 2 K wires inserted parallel to knee joint and perpendicular to the tibia.

Distal block is made with 2 K wires inserted inserted parallel to ankle and perpendicular to distal tibia.

In the transverse plane the proximal wires are in axis of the knee joint ( inter epicondylar axis) and the distal wires 15 degrees internal to bimalleolar axis

The osteotomy is made at CORA with multiple drill holes made in transverse plane and completed with 5 mm osteotome

When the wires are braught parallel the varus and the rotational deformities are corrected

The wires are connected  with miniexternal fixation clamps
