Plate characteristics

Plate head
The anatomically shaped plate head is pre-contoured to match the distal femur, eliminating intraoperative plate modification.
Five threaded 5.0 mm peripheral screw holes accept locking screws
The central 7.3mm screw has an angle of 95° to the plate shaft. Its insertion should therefore be parallel to the tibio-femoral joint surface.

Plate shaft
Combi-holes combine a dynamic compression unit (DCU) hole with a locking-screw hole. This allows the surgeon either to insert a standard bicortical screw, or a locked screw.
Straight plates are available with 6, or 8, combi-holes.
Curved plates are available with 10, 12, 14, 16, 18, 20, or 22 combi-holes, to accommodate fracture patterns that include shaft fractures in conjunction with articular fragments.
Curved plates are precontoured to mimic the anterior convexity (1.1 m radius) of the femur.
Plate design permits the use of a minimally invasive surgical techniques.
Limited-contact design provides minimal periosteal disruption.

Plate material
Implants are made from 316L stainless steel.
