Abstract
The main goal of this project has been to analyse the distribution of injected cement into vertebrae. The study has focused on the cement’s behaviour around pedicle screws inserted into lumbar (L4 and L5) and sacral (S1) vertebrae of elder people who underwent vertebroplasty. Models of the screw and cement were obtained from Computed Tomography. Once treated with CAD software, the models were ready to be studied. Longitudinal and transversal views of the maximum injected cement profiles were obtained. From these profiles, results could be obtained. They showed a tendency of injected cement into S1 vertebra to behave asymmetrically compared to a more symmetrical and homogeneous behaviour shown when injected into L4 and L5 vertebrae. Thus, leading to the assumption that pedicle screws injected into L4 and L5 vertebrae have a better chance of success than those injected into S1 vertebra.
