UNKNOWN PRIMARY TUMOR SITES IN SPINAL METASTASIS
Candido,Priscila Barile Marchi; Pinheiro,Rômulo Pedroza; Peria,Fernanda Maris; Toledo,Vinicius Nogueira; Costa,Herton Rodrigo TavaresABSTRACT Objective: The goal of the study was to report the prevalence of spinal metastasis with unknown primary tumor, clinical features, treatment results and patient survival. Methods: A retrospective evaluation of 103 patients with spinal metastasis and epidural compression, who underwent surgical treatment between March 2009 and August 2015. The prevalence of metastatic spinal tumor with unknown primary tu...
CERVICAL SPONDYLOTIC MYELOPATHY: IS A COMBINED APPROACH NECESSARY?
Teixeira,Kelsen de Oliveira; Moreno,Luis Enrique Moncada; Matos,Thiago Dantas; Fleury,Rodrigo Barra Caiado; Costa,Herton Rodrigo TavaresABSTRACT Objective: Cervical spondylotic myelopathy (CSM) is the main cause of spinal dysfunction in adults. The type of surgical approach to treatment is not well defined in the literature. The objective is to report the results obtained through isolated posterior decompression in patients with a previous indication of the combined approach for the treatment of cervical spondylotic myelopathy. Methods: This is...
COMPLICATIONS OF SURGICAL TREATMENT OF SPINAL METASTASES
Candido,Priscila Barile Marchi; Peria,Fernanda Maris; Toledo,Vinicius Nogueira; Costa,Herton Rodrigo Tavares; Defino,Helton Luiz AparecidoABSTRACT Objectives: To evaluate the complications of surgical treatment in a group of patients with spinal metastasis with epidural compression, undergoing surgical treatment. Methods: This is a comparative retrospective study (level of evidence III), which evaluated 96 patients with spinal metastases undergoing surgical treatment. Intra- and postoperative complications were obtained from the patients’ medical...
Unmet Needs of Surgical Care for Children: A Case Study in the Brazilian Public...
Bressan-Neto,Mario; Filezio,Marina Rosa; Ferri-de-Barros,Fabio; Defino,Helton Luiz AparecidoAbstract Objective To measure and document the clinical impact of the waiting time for surgical treatment of patients with spinal deformities in a quaternary center in Brazil. Methods In total, 59 patients with spinal deformity waiting for surgery on our hospital's list were evaluated to observe the impact of the waiting time on the progression of the deformity. Patient evaluation was performed using the SRS-22...
The Role of Pedicle Screw Surface on Insertion Torque and Pullout Strength
Fleury,Rodrigo Barra Caiado; Shimano,Antônio Carlos; Matos,Thiago Dantas; Teixeira,Kelsen de Oliveira; Romero,Valéria; Defino,Helton Luiz AparecidoAbstract Objective Compare by mechanical tests the pullout resistance and the insertion torque of rough and smooth pedicle screws. Methods Pedicle screws with rough surface and smooth surface, with diameters of 4.8; 5.5 and 6.5 mm, were inserted in polyurethane blocks with density of 10 PCF (0.16 g/cm3). Insertion torque and pullout strength were assessed. Results The pullout strength of the rough surface and s...
Cervical Myelopathy Secondary to Gout: Case Report
Matos,Thiago Dantas; Teixeira,Kelsen de Oliveira; Fleury,Rodrigo Barra Caiado; Costa,Herton Rodrigo Tavares; Pádua,Joel Del BelAbstract Gout is a crystalline arthropathy frequent in the population, but gouty spondyloarthropathy, also called axial gout, is uncommon. The current case report presents a rare case of cervical myelopathy secondary to axial gout. A 50-year-old female patient, without previous pathologies, presented with loss of strength, altered sensitivity, and pyramidal release for 2 years. The computed tomography showed a ...
Spinopelvic sagittal balance: what does the radiologist need to know?
Savarese,Leonor Garbin; Menezes-Reis,Rafael; Bonugli,Gustavo Perazzoli; Herrero,Carlos Fernando Pereira da Silva; Defino,Helton Luiz AparecidoSagittal balance describes the optimal alignment of the spine in the sagittal plane, resulting from the interaction between the spine and lower limbs, via the pelvis. Understanding sagittal balance has gained importance, especially in the last decade, because sagittal imbalance correlates directly with disability and pain. Diseases that alter that balance cause sagittal malalignment and may trigger compensatory...
INFLUENCE OF DIAMETER AND GEOMETRY IN THE TAPPING OF THE PILOT HOLE IN PEDICLE ...
Defino,Helton Luiz Aparecido; Miranda,Raffaello de Freitas; Pinheiro,Romulo Pedroza; Shimano,Antonio CarlosABSTRACT Objective: To evaluate the insertion torque and the pulling force of each screw with different diameters and tap. Methods: Polyurethane blocks with a pilot hole of 2.7 mm were used in the study. An experimental group with 5 blocks was formed, the insertion torque was evaluated with a torque meter, and the pullout strength of each Globus screw of 5.5 mm and 6.5 mm was assessed. Results: The comparison o...
COMPARISON OF EXPOSURE TO RADIATION DURING PERCUTANEOUS TRANSPEDICULAR PROCEDUR...
Nascimento,Anderson; Herrero,Carlos Fernando Pereira da Silva; Defino,Helton Luiz Aparecido; Viana,Marina Silva Magalhães; Araújo,João deABSTRACT Objective: To compare radiation exposure to the surgeon, patient and radiation technician during percutaneous access of the vertebral pedicle, using three different fluoroscopic imaging set up. Methods: Percutaneous access in pedicle T9-L5 of nine adult male cadavers using three different fluoroscopic set ups: standard C-arm, C-arm with L-arm, and the biplanar technique. The radiation dose exposure of ...
HEALTH-RELATED QUALITY OF LIFE AND EXPECTATIONS OF SPINAL STENOSIS PATIENTS TOW...
Nepomuceno,Eliane; Pacola,Lilian Maria; Dessotte,Carina Aparecida Marosti; Furuya,Rejane Kiyomi; Defino,Helton Luiz AparecidoABSTRACT The objective of this cross-sectional analytical study was to compare health-related quality of life, presence of anxiety and depression symptoms, and functional limitation according to the location of the spinal stenosis; and to describe patients' expectations toward the surgical treatment. Thirty-two patients with lumbar stenosis and 22 with cervical stenosis participated in the study. Comparison of ...
