Zimmer® NCB® Plating System
A locking plate system that expands a surgeon’s options in trauma surgery
The Power of Choice
The power of having true intraoperative options is at your fingertips. Using standard techniques, the NCB Plating System delivers the ability to target confidently cortical and cancellous screws with polyaxial freedom and to lock the screws, if desired, at any time during the procedure. For effective implant placement, Zimmer® Minimally Invasive Solutions(MIS ) Guides help you insert plates sub-muscularly while keeping the incision to a minimum.

MIS™ Technique
The MIS Guides allow for percutaneous targeting of screws and, thus,
smaller incisions. The radiolucent guides permit inserting of plates
sub-muscularly to help reduce stripping and damage to soft tissues.
Metadiaphyseal fractures can be left undisturbed and bridged for biologic
healing. Diaphyseal screws are angled at 8° in an alternating pattern to
resist pull-out and reduce stress-risers. In addition the screws are kept
away from prosthetics and other implants.
In the Distal Femur MIS Guide the metaphyseal screws are allowed 30° of freedom, where it is needed. The Proximal Humerus MIS Guide divergently targets metaphyseal screws. This allows for reduced risk of pull-out and addresses most fracture patterns.

Non-Contact Bridging
Spacers of 1mm, 2mm, and 3mm can be used interoperatively to hold the plate
off the bone. When the plate is “locked”, the spacers can be removed and the
construct acts like an internal fixator. Keeping the plate off the bone can
reduce the potential for periosteal damage and periosteum blood supply
impairment.

Polyaxial (Screw Choices)
The NCB Screw is secured with a locking cap that permits a range of 0°–15° off-center, or a 30° cone of polyaxiality. Cortical and cancellous screws can be used in traditional methods—lagging fragments or preventing rotation. These screws can be locked immediately after insertion, after other screws have been inserted, or not at all. With the ability to lock the construct after all screws have been inserted, screw directions can be adjusted interoperatively without having to “unlock” the construct. Because the locking cap is not inserted with power equipment, the risk of cold-welding and cross-threading is reduced.
