Percutaneous correction of Tibia Vara with mini ex fix
preoperative picture the child has varus and inernal rotation
3 year old child with tibia vara The child has varus and internal rotation deformity not correcting on serial follow up.
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
An antero posterior anti toggle wire is added to proximal and distal blocks
The fixator is removed once the osteotomy heals generally 6 weeks post op
