Proper position check - Position on the distal femur
When the plate lies flat on the lateral surface of the condyle, it has been
positioned correctly on the distal femoral articular block.
Readjust plate position, if necessary, and insert the central guide wire
into the distal femoral articular block. A second guide wire in one of the 5.0
mm screw holes will secure provisional fixation of the plate to the femoral
condyle. Its position can then be confirmed radiographically.
Prior to proceeding, confirm plate head placement. Use clinical examination
and the image intensifier to confirm that:
- the guide wire inserted through the 7.3 mm central hole is parallel to both
the tibio-femoral joint plane and the patellofemoral joint.
- the guide wires inserted through any of the four most distal 5.0 mm screw
holes in the head of the plate are parallel to the tibio-femoral joint
