- PROFILE OF SPINAL CORD TRAUMA VICTIMS TREATED AT A REFERENCE UNIT IN SÃO PAULO(2018) ARAUJO, ALEX OLIVEIRA DE; FERRONATO, DANILO DE SOUZA; ROCHA, IVAN DIAS DA; MARCON, RAPHAEL MARTUS; CRISTANTE, ALEXANDRE FOGAÇA; BARROS FILHO, TARCÍSIO ELOY PESSOA DEABSTRACT Introduction: Spinal cord trauma (SCT) is an important cause of morbidity and mortality around the world. It affects different age groups, especially young adults who are victims of high-energy trauma. The most effective way to reduce the incidence of spinal cord trauma and its consequences is through preventive campaigns and control and surveillance measures through public agencies. The objective of this study is to outline the epidemiological profile of patients with spinal cord trauma attended at a tertiary care center in the city of São Paulo. Methods: Retrospective, cross-sectional study performed at a reference center for the care of patients with spinal cord injury in the State of São Paulo. Data were collected from the medical records of patients with spinal cord trauma between 2012 and 2016. Results: Of the 515 patients with spinal trauma, 153 (29.7%) had spinal cord injury of which 131 (85.62%) were male, and 22 (14.37%) were female, in a ratio of approximately 6:1. The mean age was 39.45 years. The main cause of spinal cord trauma observed was the fall from heights, with 72 cases (47.05%), and 52.94% were classified as Frankel A. Conclusions: The results showed that the majority of the patients were young, economically active, with low educational level, exposed to accidents that could be largely avoided. Most of these patients also had severe disabling injuries, which usually bring considerable psychological sequelae and economic consequences to the individual and to society. Level of evidence: IV. Type of study: Case series.
- Fraturas do côndilo occipital: atualização da experiência em nosso serviço e revisão da literatura(2013) NORONHA, Henrique Gomes; LETAIF, Olavo Biraghi; ROCHA, Ivan Dias da; IUTAKA, Alexandre Sadao; CRISTANTE, Alexandre Fogaça; OLIVEIRA, Reginaldo Perilo de; BARROS FILHO, Tarcísio Eloy Pessoa deWe present a series of occipital condyle fractures diagnosed and treated in our hospital during the past 10 years. The present study continues an epidemiologic survey already performed in the period 1993-2000. From 2001 to 2011, six cases of fracture of the occipital condyle were diagnosed and all of them were treated conservatively, except one, in which a halo was initially placed. In the five cases treated conservatively, there were good results, with stable segment in functional radiographs, absence of limitation of motion and no pain. The patient treated with halo had FRANKEL C partial quadriplegia and associated fractures (C5, C6, L1, and L2), showing no neurological improvement, besides observing cervical motion limitation. We also highlight the importance of active research on lesions in the occipital-cervical transition, particularly in cases resulting from high-energy trauma, because in addition to the clinical implications of early detection of fracture, the best use of ancillary tests have been an important factor for the increased incidence of fractures of the occipital condyle. As is historically reported, conservative treatment is still effective and has a low rate of complications, and surgical treatment should be indicated in cases with established instability.
- TOMOGRAPHIC STUDY OF THE S2-ALAR-ILIAC SCREW TECHNIQUE IN BRAZILIAN MEN(2019) SOMBRA, LUIS PIMENTEL; SILVA, RICARDO TEIXEIRA E; ARAÚJO, THIEGO PEDRO FREITAS; BIRAGHI, OLAVO LETAIF; MARCON, RAPHAEL MARTUS; CRISTANTE, ALEXANDRE FOGAÇA; BARROS FILHO, TARCÍSIO ELOY PESSOA DEABSTRACT Objective The use of pedicle screws was a milestone for modern spinal surgery. This type of fixation, due to its superior biomechanics, gave greater fixation power, greater capacity to withstand the pulling forces and, therefore, greater stability and lower rates of pseudoarthrosis. Fixation of the lumbosacral junction, even with the development of these new implants, remains a challenge mainly because the considerable rates of pseudoarthrosis. The use of iliac screws solves the biomechanical difficulties. However, its use shows high rates of surgical wound problems. The S2-Alar-Iliac screw (S2AI) came as a solution to these complications. The lack of studies about anatomical and anthropometric parameters in the Brazilian population justifies the study. Methods Eleven hip tomographies of Brazilian adult males were analyzed by four evaluators. The right and left sides were considered. In each patient, measurements were made of greater and shorter bone length, greater and smaller bone diameter, distance from the entry point to the skin, sagittal and axial angles related to the hypothetical insertion of an S2AI screw and compared to the same measurements obtained with the iliac screw. Results The mean bone length was 136.7 mm, the greatest bone diameter was 24.8 mm, the smallest bone diameter was 19.7 mm and the distance from the screw to the skin was 42.1 mm for the S2AI screw. Conclusions The obtained data present an average of the sample that can be useful in the decision of the surgical technique in the studied group. Level of evidence I; Diagnostic Studies (Anatomical Investigation).
- Avaliação de série de pacientes com artrodese C1-C2(2012) GHILARDI, Cesar Salge; LETAIF, Olavo Biraghi; IUTAKA, Alexandre Sadao; CRISTANTE, Alexandre Fogaça; ROCHA, Ivan Dias; MARCON, Raphael Martus; OLIVEIRA, Reginaldo Perilo; BARROS FILHO, Tarcísio Eloy Pessoa deOBJECTIVE: Retrospective record analysis of patients with C1-C2 instability of traumatic and nontraumatic causes who underwent C1-C2 arthrodesis. METHODS: We performed retrospective analysis of medical records of 20 outpatients from the column of IOT-FMUSP aged between 7 and 83 years (mean 43 years) of both sexes. The radiographic parameters for instability were based on measurement of atlanto-axial interval greater than 3 mm in adults and 5 mm in children, using measures obtained from lateral plain X-rays. RESULTS: We operated 20 patients with high cervical instability, mostly due to trauma. The surgical technique used was that described by Magerl. There were no vascular injuries. Infectious complications were reported in two patients. We achieved a solid fusion rate of 85% and no revision surgeries were required. CONCLUSIONS: All techniques produced satisfactory bone healing and were excellent for the control of atlanto-axial instability.
- TOMOGRAPHIC ANALYSIS OF SUBAXIAL CERVICAL VERTEBRAE IN CHILDREN BETWEEN 0 AND 12 YEARS(2017) MACHADO, LUCAS CASTRILLON CARMO; LETAIF, OLAVO BIRAGHI; MARCON, RAPHAEL MARTUS; CRISTANTE, ALEXANDRE FOGAÇA; OLIVEIRA, REGINALDO PERILO; BARROS FILHO, TARCÍSIO ELOY PESSOA DEABSTRACT Objective: Tomographic and anatomic analysis of cervical vertebrae in children from 0 to 12 years of age to verify the possibility of utilization of lateral mass screws. Methods: Twenty-five cervical spine tomographies of children between 0 and 12 years of age, admitted to the emergency room of Hospital das Clínicas of São Paulo were retrospectively analyzed. The following distances were measured: width and length of the lateral masses in the axial section; width and height in the coronal section; height, length and diagonal diameter in the sagittal section. The variables studied were correlated with age and sex and submitted to statistical analysis. Results: The analysis of tomographic measurements of 20 patients showed a correlation between age and dimensions of the lateral mass, which were higher after 6 years of age. In relation to sex, greater measures were observed in males in all axes. With regard to the passage of the screws, we only had 22 masses (11%) that prevented their use. However, when stratified by age, we noticed that no patients had restrictions on the use of the lateral mass screw after the age of 6. Conclusion: This study analyzed the measurements of 200 lateral masses, making it possible to infer that there is an increase of dimensions with age and in males. Through the data, it was possible to affirm that in this sample, considering the implants available in the market, the lateral mass screws could be used in 89% of the lateral masses.
- COMPLICATIONS AFTER PARTIAL, TOTAL OR EXTENDED SACRECTOMY: A CASE SERIES(2021) FERRONATO, DANILO DE SOUZA; TAVARES JUNIOR, MAURO COSTA MORAIS; NARAZAKI, DOUGLAS KENJI; GHILARDI, CESAR SALGE; TEIXEIRA, WILLIAM GEMIO JACOBSEN; CRISTANTE, ALEXANDRE FOGAÇA; BARROS FILHO, TARCISIO ELOY PESSOA DEABSTRACT Objective The aim of this study was to conduct a survey of the different complications of partial, total or extended sacrectomy for the treatment of spinal tumors. Method This study is a descriptive analysis of medical records from a series of 18 patients who underwent sacrectomy between 2010 and 2019 at a tertiary center specializing in spinal tumor surgeries. The variables analyzed were sex, age, hospitalization time, oncologic diagnosis, posterior fixation pattern, rate of complications, and Frankel, ASA and ECOG scales. Results Of the 18 patients, 10 (55.5%) were male and 8 (44.5%) were female, and the mean age was 48 years. The mean hospitalization time was 23 days. Of the 18 patients, 8 (44.5%) contracted postoperative infections requiring surgery. Perioperative complications included liquoric fistula (22.25%), hemodynamic instability requiring vasoactive drugs in the immediate postoperative period (22.25%), wound dehiscence (11.1%), acute obstructive abdomen (11.1%), occlusion of the left external iliac artery (11.1%), immediate postoperative death due to acute myocardial infarction (11.1%), and intraoperative death due to hemodynamic instability (11.1%). Conclusions Partial, total or extended sacrectomy is a complex procedure with high morbidity and mortality, even in centers specializing in the treatment of spinal tumors. Level of evidence IV; case series study.
- Transcorporeal cervical foraminotomy: description of technique and results(2014) MEYER, Guilherme Pereira Corrêa; CHOI, Gun; BANDHARKAR, Amit; CHOI, Pil Sun; LEE, Sang Ho; CRISTANTE, Alexandre Fogaça; MARCON, Raphael Martus; IUTAKA, Alexandre Sadao; BARROS, Tarcísio Eloy Pessoa deOBJECTIVE: Retrospective analyses of 216 patients undergoing foraminal decompression with transcorporeal approach and review of the surgical technique. METHOD: 216 patients with minimum follow-up of 2 years and an average of 41.8 months were included in the study. The clinical records of these patients were reviewed for complications, NDI (neck disability index) and VAS (visual analogue scale). Pre and post-operative radiographs were used to evaluate the disc height. RESULTS: At the end of follow-up patients had significant clinical improvement with reduction of NDI of 88.3% and 86.5% and 68.3% of the VAS for neck and upper limb, respectively (p<0.05). A reduction of 8.8% of the disc height was observed without other complications associated (p<0.05). CONCLUSION: Radicular decompression through a transcorporeal approach is an alternative that provides good clinical results without the need for a fusion and with few complications.
- 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.
- COMPARISON BETWEEN START BACK SCREENING TOOL AND DRAM FOR DETECTION OF PSYCHOSOCIAL FACTORS IN LOW BACK PAIN(2021) TUCCI, Carlos; ARAUJO, Alex Oliveira de; MARCON, Raphael Martus; CRISTANTE, Alexandre Fogaça; BARROS FILHO, Tarcísio Eloy Pessoa deABSTRACT Objective: To correlate the results of the STarT Back Screening Tool and DRAM questionnaires, applied simultaneously, in a population with low back pain. Methods: Comparative cross-sectional study with 84 participants with low back pain assessed by both STarT Back Screening Tool (SBST) and DRAM questionnaires. The degree of correlation between the two questionnaires was analyzed through the evaluation of individualized data and using the Spearman correlation coefficient. Results: According to the DRAM, 19% of the patients were classified as “normal”, 32.1% as “at risk” and 48.8% as “distressed”. According to SBST, 59.5% of patients were classified as “low risk”, 31% as “medium risk” and 9.5% as “high risk”. Applying the Spearman's coefficient to evaluate the degree of correlation between the two questionnaires, a value of 0.4 was obtained. This shows that there is a positive, but weak, correlation (p <0.001) between the two questionnaires. Conclusion: There is a positive correlation between the two questionnaires, but the DRAM showed a greater tendency to classify patients with some degree of psychological distress when compared to the SBST. Both questionnaires are effective in identifying these factors, but the data suggest that the DRAM may be more effective as a screening tool in patients with low back pain, in view of the higher number of patients identified. Level of evidence III; Diagnostic test study.
- Cervical disc prosthesis: 2-year follow-up(2015) BILHAR, Romero Pinto de Oliveira; CRISTANTE, Alexandre Fogaça; MARCON, Raphael Martus; ROCHA, Ivan Dias da; LETAIF, Olavo Biraghi; BARROS FILHO, Tarcísio Eloy deTo review the medical records of patients who underwent surgery for placement of cervical disc prosthesis after two years of postoperative follow-up, showing the basic epidemiological data, the technical aspects and the incidence of complications. METHODS: Medical records of seven patients who underwent surgery for placement of cervical disc prosthesis were reviewed after two years of follow-up, at the Institute of Orthopedics and Traumatology, Faculty of Medicine, University of São Paulo. RESULTS: The average age of patients participating in this study was 43.86 years. Six patients (85.7%) had one level approached while one patient (14.3%) had two levels addressed. The level C5-C6 has been approached in one patient (14.3%) while the C6-C7 level was addressed in five patients (71.4%). One patient (14.3%) had these two levels being addressed, C5-C6 and C6-C7. The mean operative time was 164.29±40 minutes. Three patients were hospitalized for 2 days and four for 3 days making an average of 2.57±0.535 days. Two patients (28.6%) underwent a new surgical intervention due to loosening of the prosthesis. The mean follow-up was 28.14±5.178 months (23-35 months). CONCLUSIONS: Although cervical arthroplasty appears to be a safe procedure and present promising results in our study as well as in many other studies, it requires long-term studies.
