Anterior cement augmentation of adjacent levels after vertebral body replacement leads to superior stability of the corpectomy cage under cyclic loading – a biomechanical investigation

In the operative treatment of osteoporotic vertebral body fractures, a dorsal stabilization in combination with a corpectomy of the fractured vertebral body might be necessary with respect to the fracture morphology, whereby the osteoporotic bone quality may possibly increase the risk of implant failure. In order to achieve better stability, it is recommended to use cement-augmented screws for dorsal instrumentation. Beside careful endplate preparation cement augmentation of the adjacent endplates has also been reported to lead to less reduction loss.
