The Polyaxial Large Fragment Plate Portfolio The NCB (Non-Contact Bridging) Large Fragment System is a line of polyaxial locking plates for the treatment of femur, tibia and humerus shaft fractures. It consists of a Curved Femur Shaft plate and a Straight Narrow Shaft Plate. The NCB Curved Femur Shaft Plate is also included in the NCB Periprosthetic Femur Polyaxial Locking Plate System. Symmetric Design There is only one plate for left and right long bones due to symmetric design. The NCB Straight Narrow Shaft Plate can either be used for the tibia or humerus. Whereas the NCB Curved Femur Shaft Plate is specifically designed for the femur. K-Wire Holes Two k-wire holes at each end of the plate allow easier preliminary plate fixation. Compression Slots Two compression slots allow 1mm of compression each.
