N2 - PURPOSE OF THE STUDY To compare the anchorage strength of Socon CS cannulated pedicle screws (B. Braun, Aesculap) with that of Socon screws in human cadaver vertebrae, using pull-out strength testing. Twelve samples involving T12 to L3 vertebrae were prepared and a total of 20 pedicle screws, 10 Socon CS and 10 Socon screws, were inserted in them. All screws were 55 mm in length and 6 mm in diameter. After placement, Socon CS pedicle screws were augmented with bone cement (Cimplant cement application kit, B. Braun, Aesculap). The poor quality of osteoporotic bone is responsible for a higher frequency of implant failure due to loosening, particularly when implants developed for healthy bone are used. In this biomechanical study, we tested one of the possibilities of how to reduce the risk of implant failure by pedicle screw augmentation with bone cement. The results of this study confirm the hypothesis that the anchorage of Socon CS cannulated pedicle screws with bone cement augmentation is disrupted by significantly higher pull-out strength than that of Socon screws, when subjected to monotonous loading. However, more clinical studies are needed to evaluate clinical outcomes.
