文摘
- •
Rigid instrumentations are used for spinal fusion.
- •
Adjacent segment diseases are frequent complications associated with rigid constructs.
- •
Stabilization capacity of rod with variable stiffness was evaluated in vitro.
- •
Stiffness variation of the rods has a moderate effect when pedicle screws are used.
- •
Transverse hooks at the end of the construct amplify the effect of the rods' stiffness.
