Plate and splint construct testing on cadaveric rib model1
The Synthes MatrixRIB Fixation System was tested in a cadaveric model to withstand five times higher than normal in-vivo loads2 for a duration representative of more than 2 weeks of fracture healing (360,000 cycles)3. Furthermore, a second group of plates were mounted on plastic test blocks and subjected to 15 times higher-than-normal in vivo loads2 for a duration representative of more than 6 weeks of fracture healing (1,000,000 cycles)3.

Cadaveric rib plate and splint testing summary1
Bending stiffness of plate testing constructs was comparable to unfractured cadaveric osteoporotic rib (Figure 1). All plate and splint constructs survived exaggerated dynamic loading (bending loads 5 times greater than respiration for 360,000 cycles) in a cadaveric model without construct failure. Plate and splint constructs retained sufficient strength after dynamic loading to support loads greater than respiration at an exaggerated level (Figure 2). Splint construct provided stable fixation during the dynamic loading with no observed implant migration.	Figure 1 Figure 2
Bench testing on plastic blocks1
Plates survived bending loads approximately 15 x greater than respiratory loading (600 Nmm) for 1,000,000 cycles.
