Non-Contact bridging with polyaxial screw placement.
Freedom of Choice
The NCB® Proximal Humerus Plating System allows controlled targeting of cortical and cancellous screws with polyaxial freedom. The system allows the surgeon to lock the screws at any time during the procedure by using locking caps that are threaded into the plate holes. This locking construct improves angular stability such as fractures in osteopenic bone.1*
- Shoulders and Elbows
- Plates and Screws
The NCB Screws (solid and cannulated) are available with different types of screw thread, for cortical or cancellous bone. The screws designed for cortical bone have an increased core diameter and are designed with a double lead thread for fast insertion. Cannulated screws can be placed with high precision – no predrilling is required as they are self-drilling and self-tapping. 4.5mm cancellous and 4.0mm cortical screws are available.
Enhance Diaphyseal Fixation
- Aims to provide divergent screw alignment for increased pull-out resistance in the diaphyseal region, even with the MIS Targeting Device.
- Before locking, NCB Screws can act as lag screws. Therefore, NCB Screws can be used for fracture reduction and apply interfragmental compression, a feature not offered with conventional locking systems.
- In the locked mode the NCB Plate acts as an internal fixator without contact between the plate and the bone surface, which is intended to minimize impairment to the periosteal blood supply. This Non-Contact Bridging concept can also be controlled through the use of 1, 2 or 3mm spacers, which are threaded into the plate holes prior to plate insertion.
