The NCB Periprosthetic Trochanter Plate always needs to be assembled with a NCB Periprosthetic Proximal Femur Plate. It is available in two different sizes (different width) whereas the height is the same. Due to the anatomical shape of the proximal femur a left and a right version is offered. The Trochanter Plates offer usage of 3.5mm ULS locking screws or cortical screws (non-locking) to reattach the greater Trochanter.

The NCB Periprosthetic Proximal Femur Plate is a  polyaxial locking plate for the treatment of femur fractures, including periprosthetic femur fractures. Innovative plate design combined with the polyaxial NCB Locking Plate Technology offers solutions for fixation of particularly complex periprosthetic fractures.

The distal and proximal NCB Periprosthetic Plates provide a diagonal three hole pattern, which allows for multiple screw options:
• Offset holes allow for easier screw placement around the prosthesis and may allow bicortical fixation.
• The central screw holes can accommodate threaded 5.0 mm unicortical Screws, threaded Cable Buttons and Cables (when bicortical screw fixation can not be achieved).

• Reduced and uniform plate stiffness
• Better plate contouring across solid cross-sections, away from holes.

The NCB Plate Technology allows polyaxial screw placement (30° cone) with screw locking achieved through the use of locking caps that are threaded into the plate holes. The locking construct allows for  improved stability especially in osteopenic bone.

In the locked mode the NCB Periprosthetic Plate acts as an internal fixator without contact between the plate and the bone surface, which may reduce the risk of impairment to the periosteal blood supply. This Non-Contact Bridging concept can also be controlled through the use of 1, 2, or 3 mm spacers, which are threaded into the plate holes prior to plate insertion.

Five different NCB Screw types are offered with the NCB Periprosthetic Femur System, to allow both bicortical and unicortical fixation.

The NCB Cable Button, Hex Button and Cable Assembly Cerclage from the Zimmer® Cable-Ready® Cable Grip System are compatible with the NCB Periprosthetic Femur System.

Slightly oversized drill bits and drill guides are offered with the NCB Periprosthetic Femur System, that may help reduce the risk of cracks in the cement mantle when placing screws around a cemented prosthesis.

Before locking, NCB Screws can also act as lag screws. Therefore, when used with NCB Periprosthetic plates, NCB Screws can be used for fracture reduction and to apply interfragmentary compression, a feature not offered with conventional locking systems.
