Influence of endplate size and implant positioning of vertebral body replacements on biomechanics and outcome.

Background: Spinal stabilization by an anterior vertebral body replacement is frequently used in patients suffering from destroyed vertebral bodies. The aim of this study was to analyse (i) the choice of endplate size and positioning of vertebral body replacements in daily patient care and (ii) if these factors have an influence on clinical and radiological outcomes.

Method: Patients' outcomes were analysed three years after vertebral body replacement implantation using the visual analogue scale spine score.
