INDIRECT DECOMPRESSION BY LATERAL FUSION: ANALYSIS OF SAGITAL ALIGNMENT
Silva,Thyago Guirelle; Amaral,Rodrigo Augusto do; Pratali,Raphael Rezende; Pimenta,LuizABSTRACT Objective: To verify the effectiveness of indirect decompression after lateral access fusion in patients with high pelvic incidence. Methods: A retrospective, non-comparative, non-randomized analysis of 22 patients with high pelvic incidence who underwent lateral access fusion, 11 of whom were male and 11 female, with a mean age of 63 years (52-74), was conducted. Magnetic resonance exams were performe...
Pedicle Screws and Facet Violation - The importance of the Angle between the Fa...
Amaral,Rodrigo; Pimenta,Luiz; Guarçoni Netto,Angelo; Pokorny,Gabriel Henrique; Fernandes,RaquelAbstract Objective To verify whether, regardless of the screw placement technique, there is a safe distance or angle in relation to the facets that can prevent violation of the facet joint when the screws are placed. Methods Retrospective, single, comparative, non-randomized center. We evaluated by axial computed tomography: the angle of the screw/rod in relation to the midline, the angle of the center of the f...
L5-S1 SURVIVAL AFTER INTERBODY FUSION BY LATERAL APPROACH UNTIL L5 IN DEGENERAT...
Silva,Fernando Toni Marcelino da; Marchi,Luis; Pokorny,Gabriel; Amaral,Rodrigo; Jensen,Rubens; Pimenta,LuizABSTRACT Objectives: Whether or not to include L5-S1 in multiple level lumbar fusions is not yet a consensus in the literature. The option to preserve L5-S1 maintains the mobile segment and the possibility of a natural fit to the sagittal alignment of the lumbar spine. However, a long fusion above L5-S1 may accelerate the degenerative process and an extension to the sacrum may be necessary in the future. In thi...
TRANSLATION AND ADAPTATION OF THE “LUMBAR STIFFNESS DISABILITY INDEX” QUESTIONN...
Guarçoni Netto,Angelo; Marchi,Luis; Pokorny,Gabriel; Amaral,Rodrigo; Jensen,Rubens; Pratali,Raphael; Herrero,Carlos Fernando; Jacob Junior,CharbelABSTRACT Objective: To develop a version of the Lumbar Stiffness Disability Index (LSDI), translated into Portuguese and culturally adapted for the Brazilian population. Methods: The well-established process of translation into Portuguese and back translation into English was used together with cultural adaptation. Results: Five bilingual translators (English and Portuguese) performed the translation of the Lum...
WORKERS' COMPENSATION IS ASSOCIATED WITH WORST CLINICAL RESULTS AFTER LUMBAR FU...
Marchi,Luis; Nogueira-Neto,Joes; Amaral,Vivian; Amaral,Rodrigo; Faulhaber,Nicholai; Coutinho,Etevaldo; Oliveira,Leonardo; Jensen,Rubens; Pimenta,LuizABSTRACT Objective: The objective of this study was to evaluate the association of clinical results with preoperative situation of worker compensation (WC) in patients submitted to spine surgery. Methods: This was a retrospective, comparative, single center study. Patients who underwent lumbar spine arthrodesis were included. The outcomes were pain scores (VAS), physical constraint (ODI) and quality of life (EQ...
Stand-alone anterior lumbar interbody fusion - complications and perioperative ...
Amaral,Rodrigo; Ferreira,Ronaldo; Marchi,Luis; Jensen,Rubens; Nogueira-Neto,Joes; Pimenta,LuizABSTRACT Objectives: Historically, anterior lumbar interbody fusion (ALIF) was related to high rates of intraoperative complications and adverse events related to interbody devices. In recent decades, there have been technical adjustments, and cages that are more suitable have emerged. The aim of this study is to evaluate the efficacy and complication rate of the use of stand-alone mini-ALIF using a self-lockin...
REPRODUCIBILITY AND EQUIVALENCE OF COBBMETER APPLICATION IN THE SAGITTAL EVALUA...
Marchi,Luis; Fortti,Fernanda; Amaral,Rodrigo; Oliveira,Leonardo; Nogueira-Neto,Joes; Jensen,Rubens; Pimenta,LuizABSTRACT Objective: This study aims to evaluate the reliability and equivalency of using the Cobbmeter application for iPhone compared to the manual measurement method in the analysis of the sagittal spinal alignment. Methods: Cross-sectional, prospective, single-center study that had 20 panoramic radiographs of the spine in lateral view, in a neutral standing position, analyzed blindly and randomly by three in...
MORPHOMETRIC STUDY OF THE AREOLAR SPACE BETWEEN THE GREAT VESSELS AND THE LUMBA...
Marchi,Luis; Oliveira,Leonardo; Amaral,Rodrigo; Fortti,Fernanda; Pimenta,Luiz; Abdala,NitamarObjective : This work aims to study the areolar space anterior to the lumbar spine, and also the positioning of the large vessels focusing a lateral approach. Methods :This is a morphometric study of 108 cases based on T2 weighted-MRI images in the supine position. The following measurements were performed: lumbar and segmental lordosis; anteroposterior disc diameter; space between the disc/vertebral body and t...
IMMEDIATE RECIPROCAL CHANGES AT ADJACENT LEVEL FOLLOWING SINGLE-LEVEL ALIF
Uribe,Enrique Vargas; Amaral,Rodrigo; Marchi,Luis; Jensen,Rubens; Oliveira,Leonardo; Fortti,Fernanda; Coutinho,Etevaldo; Pimenta,LuizObjective : To assess the segmental sagittal parameters and the adjacent mobile segment after interbody fusion by anterior approach in single-level L5-S1. Methods : Retrospective study. Inclusion: Interbody fusion by anterior approach (10°/15° angle), due to DDD, low-grade spondylolisthesis and/or stenosis without prior lumbar fusion. Thirty-five cases were included (25 women; mean age 47±15 years). Analysis of...
Up-to-date thromboprophylaxis in elective spinal surgery. A systematic review
Oliveira,Leonardo; Marchi,Luis; Pimenta,LuizDeep vein thrombosis (DVT) and pulmonary embolism (PE) present a high incidence after surgery, posing a high risk in surgical practice. Although a consensus does exist on thromboprophylaxis in orthopedic surgery, this topic remains controversial in regard to spinal surgery. In this current paper, we review and discuss the different forms of prophyilaxis presented in literature, in order to develop guidelines on...
