NCB® Periprosthetic Femur Plate System

The Polyaxial Locking Plate portfolio

The NCB (Non-Contact Bridging) Periprosthetic Femur Plate System is a line of polyaxial locking plates for the treatment of femur fractures, particularly periprosthetic femur fractures. Innovative plate designs combined with the polyaxial NCB Locking Plate Technology offer solutions for fixation of particularly complex periprosthetic fractures. The system consists of a Proximal Femur plate, a Distal Femur plate, and a Curved Femur Shaft plate.

Diagonal Three Hole Pattern

All 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 Unicortical Screws, Cable Buttons and Cables

Differently Shaped Scallops

  • 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 improves stability especially in poor bone quality.

Broad Screw Options

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

Non-Contact Bridging

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.

Cable Fixation Options

The products from the Zimmer ® Cable-Ready ® Cable Grip System are compatible with the NCB Periprosthetic Femur System.

Specific Instruments for Periprosthetic Fractures

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

NCB Curved Femur Shaft Plate

Symmetric Design

There is one plate for left and right femurs due to symmetric design.

Compression Slots

Two compression slots allow 1 mm of compression each.

Articulated Tension Device Holes

One hole at each end of the plate allows for connection of the Articulated Tension Device to achieve additional compression, if needed.

NCB Distal Femur Plate

95° Angled Distal Hole

The most distal central plate hole is angled at 95° to the plate shaft to allow screw insertion parallel to the joint. This may help reduce the fracture and facilitate realignment of the anatomic axis of the femur.

Fracture Reduction

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