Prophylactic local treatment involving percutaneous vertebral augmentation using bioactive materials is a new treatment strategy in spine surgery in humans for vertebral bodies at risk. Standardized animal models for this procedure are almost non-existent. The purpose of this study was to: (i) prove the efficacy of PTH derivate bioactive materials for new bone formation; and (ii) create a new, highly standardized cervical vertebral augmentation model in sheep. Three different concentrations of a modified form of parathyroid hormone (PTH) covalently bound to a fibrin matrix containing strontium carbonate were used. The same matrix without PTH and shams were used as controls. The bioactive materials were locally injected. Using a ventral surgical approach, a pre-set amount of material was injected under fluoroscopic guidance into the intertrabecular space of three vertebral bodies. Intravital fluorescent dyes were used to demonstrate new bone formation. After an observation period of four months, the animals were sacrificed, and vertebral bodies were processed for µCT, histomorphometry, histology and sequential fluorescence evaluation. Enhanced localized bone activity and new bone formation in the injected area could be determined for all experimental groups in comparison to the matrix alone and sham with the highest values detected for the group with a medium concentration of PTH.
