Kalil Pessoa de; TARICCO, Mario Augusto; OLIVEIRA, Reginaldo Perilo; MARCHESE, Luiz Roberto Delboni; CRISTANTE, Alexandre Fogaça; MEVES, Robert- TOMOGRAPHIC ANALYSIS OF T-1 VERTEBRA TO INSERT LAMINAR SCREWS IN CHILDREN FROM 0 TO 12 YEARS(2015) MARCHESE, Luiz Roberto Delboni; LETAIF, Olavo Biraghi; MARCON, Raphael Martus; CRISTANTE, Alexandre Fogaça; OLIVEIRA, Reginaldo Perilo; BARROS FILHO, Tarcísio Eloy Pessoa deObjective : Tomographic analysis of the T1 vertebra in children from 0 to 12 years of age, in order to obtain anatomical parameters that assist intralaminar fixation in this pediatric population. Methods : Retrospectively analysis of the spine with CT (cervical and thoracic) of individuals aged between 0 and 12 years old, of both sexes, without anatomical deformities. The CT scans were evaluated separately, on each side, for length and thickness of the laminas as well as spinolaminar angle. The morphometric analysis was performed with iSite PACS Philips Healthcare Informatics(r) program and the values were expressed in millimeters (mm). The variables were correlated with age groups and sex of individuals. Statistical analysis was performed using t test and the results were considered significant when p<0.05. Results : By means of tomographic analysis of 24 patients it was found that age has no correlation with the angle of attack for intralaminar screws T1. However, the length and thickness of the T1 lamina increase proportionally with age. The total average length of the laminas was 28.62 ± 4.42 mm. The total average thickness was 4.75 ± 0.95 mm (3.2 to 6.5). Conclusion : This study shows relevant data on the use of Tran laminar screws currently commercially available with a minimum thickness of 3.5 mm. It is thus possible to say in this sample, they can be used in 87.5% of all laminas, being applicable in all lamina in patients older than 44 months of age.
- TOMOGRAPHIC CORRELATION OF THE MAGERL TECHNIQUE FOR C1-C2 ARTHRODESIS IN RHEUMATOID ARTHRITIS(2013) MARCHESE, Luiz Roberto Delboni; BONADIO, Marcelo Batista; LETAIF, Olavo Biraghi; CRISTANTE, Alexandre Fogaca; OLIVEIRA, Reginaldo Perilo; BARROS FILHO, Tarcisio Eloy Pessoa deObjective: To use the tomographic analysis of C1 and C2 vertebrae to assess the possibility of using Magerl's technique in patients with rheumatoid arthritis. Other objectives were to obtain anatomical data for the choice of the surgical technique in general, to establish safety parameters and obtain epidemiological data of the population in question. Methods: We retrospectively reviewed the CT scans of 20 patients with rheumatoid arthritis of the Outpatient Spine Group, IOT-HCFMUSP. Data were analyzed statistically to obtain the mean values and the variance of each measurement: the length of the C2 pedicle to the C1 lateral mass, the thickness of the pedicle and the angle of attack of the screw in the isthmus of C2 to the horizontal. Results: The mean values were, respectively: right 23.08 mm and left 23.16 mm, right 6.46 mm and left 6.50 mm, right 44.50 degrees and left 44.95 degrees. Discussion: The leading screw's manufacturers have implants compatible with the anatomical measurements found in this work. Considering the wide diffusion and mastery of Magerl's technique in our country and around the world, this is a safe surgical option that provides mechanical stability. Conclusion: Magerl's technique, according to tomographic analysis, can be used in patients with rheumatoid arthritis. Levels of Evidence IV, Case Series.
