The cortex from the TBW must be strong enough to bear
the applied compressive loads

Biomechanics
The implant alone does not provide stability. In combination with
antagonistic deforming muscles, it can help produce uniform
compression at the fracture site. It guides the compression force.
The parallel wires serve as rails along which the bone fragments
slide.
