Energy Required for Fracture in Synthetic Proximal Femoral Models After Synthes...
Freitas,Anderson; Silva,Landwehrle de Lucena da; Costa,Renilton Rodrigues; Ramos,Lucas Sacramento; Giordano,Marcos Norberto; Gonçalves,Henrique MansurAbstract Objective The present study aims to identify the energy required for synthetic proximal femoral fracture after removal of three implant types: cannulated screws, dynamic hip screws (DHS), and proximal femoral nail (PFN). Methods Twenty-five synthetic proximal femur bones were used: 10 were kept intact as the control group (CG), 5 were submitted to the placement and removal of 3 cannulated screws in an ...
Evaluation of the Reproducibility of Lauge-Hansen, Danis-Weber, and AO Classifi...
Ramos,Lucas Sacramento; Gonçalves,Henrique Mansur; Freitas,Anderson; Oliveira,Marcio de Paiva; Lima,Diogo Marcelino Santos; Carmargo,Welvis SoaresAbstract Objective The present study aims to analyze the intra- and interobserver reproducibility of the Lauge-Hansen, Danis-Weber, and Arbeitsgemeinschaft für Osteosynthesefragen (AO) classifications for ankle fractures, and the influence of evaluators training stage in these assessments. Methods Anteroposterior (AP), lateral and true AP radiographs from 30 patients with ankle fractures were selected. All imag...
Mechanical Analysis after Proximal Femoral Reinforcement with Polymethylmethacr...
Freitas,Anderson; Lessa,Mariana de Medeiros; de Oliveira,Saulo Pereira; de Oliveira,Pedro Félix Pereira; Giordano,Vincenzo; Shimano,Antônio CarlosAbstract Objective To evaluate, through a biomechanical assay, the maximum load, energy, and displacement necessary for the occurrence of fractures in synthetic models of femurs after the removal of cannulated screws and the performance of a reinforcement technique with polymethylmethacrylate (PMMA) in different combined positions. Methods In total, 25 synthetic bones were used, and they were divided into 4 gro...
Tenotomy of the Gluteus Maximus in Total Hip Arthroplasty with Prevention of Sc...
Paiva,Leonardo Morais; Oliveira,Karina Maria Alécio de; Souto,Diogo Ranier de Macedo; Macedo Neto,Sílvio Leite de; Kircov,Nicolay Jorge BonvineAbstract The authors report a single case of complex primary hip total arthroplasty in a 34-yearold female patient with a 5.5 cm lower limb dysmetria, in whom a maximum gluteus tenotomy was performed in order to prevent sciatic nerve injury. The surgery was performed under electroneurophysiological monitoring of the fibular and tibial branches of the sciatic nerve, collecting pretenotomy, posttenotomy, and post...
Biomechanical Test after Hip Cannulated Screw Removal (in vitro Analysis)
Freitas,Anderson; Ramos,Lucas S.; Dantas,Érgon LAB; Giordano Neto,Vincenzo; Godinho,Patrick F.; Shimano,Antônio C.Abstract Objective This study aims to evaluate, through biomechanical tests, the resistance and energy required for proximal femoral fracture in synthetic bones after removing cannulated screws shaped as an inverted triangle, comparing the obtained results to those of a reinforcement technique with polymethylmethacrylate (PMMA) as bone cement. Methods Twenty synthetic bones were used: 10 units for the control g...
Cost and Safety Evaluation of Simultaneous Bilateral Total Knee Arthroplasty ve...
Borges,José Humberto de Souza; Lobo Júnior,Paulo; Dias,Darlan Malba; Silva,Miguel Fernando Ferreira da; Freitas,Anderson; Araújo,ThaianeAbstract Objective To measure the cost of simultaneous total knee arthroplasty, as well as the costs of total and intensive care unit (ICU) length of stay, perioperative complications and need for blood transfusion compared to the costs of unilateral procedure in a referral hospital, in Federal District, Brazil. Method The present article is a retrospective study analyzing the medical records of patients admitt...
PRELIMINARY MECHANICAL TEST OF PROXIMAL FEMUR REINFORCEMENT WITH CEMENTED X-SHA...
Freitas,Anderson; Camargo,Welvis Soares; Aquino,Ruben Jeri; Giordano Neto,Vincenzo; Bonavides Junior,Aluízio Fernandes; Shimano,Antônio CarlosABSTRACT Objective: To evaluate the mechanical behavior of the proximal end of the femur submitted to the X-shaped polymethylmethacrylate (PMMA) reinforcement technique. Methods: Fifteen synthetic femurs, with a Nacional® density of 10 PCF, were divided into two groups: the DX group, with 5 units that were submitted to PMMA reinforcement, and the DP group, with 10 units, which were evaluated intact. The volume ...
Static bending test after proximal femoral nail (PFN) removal - in vitro analysis
Paiva,Leonardo Morais; Macedo Neto,Sílvio Leite de; Souto,Diogo Ranier de Macedo; Ferreira,George Neri Barros; Costa,Hélio Ismael da; Freitas,AndersonAbstract Objective To evaluate, through biomechanical testing, the resistance to and energy required for the occurrence of proximal femoral fracture in synthetic bone after removal of a proximal femoral nail model (PFN), comparing the results obtained with a reinforcement technique using polymethylmethacrylate (PMMA). Methods Fifteen synthetic bones were used: five units for the control group (CG), five for the...
Can be the cement augmentation an improvement method of preventing hip fracture...
Freitas,Anderson; Neri,George; Neto,Silvio Leite de Macedo; Borges,João Lindolfo Cunha; Paula,Ana Patrícia de<p><b>INTRODUCTION:</b> The population around the world is aging. With this, there will be an increased incidence of fractures due to osteoporosis of the hip and this will be a serious global health problem. A World Health Organization (WHO) estimate suggests that the incidence of hip osteoporotic fractures worldwide will triple by 2050.<br> <b>OBJECTIVE:</b> To present, through a literature review, the main re...
Proposta de teste clínico para auxílio diagnósitco e avaliação terapêutica das ...
Freitas,Anderson; Godinho,Patrick F; Neto,Silvio L M; Costa,Helio I da; Giordano,Marcos N; Cabrita,Henrique A B AAs tendinites glúteas são patologias muito freqüentes na rotina diária nos consultórios ortopédicos, na maioria das vezes diagnosticada clinicamente de forma subjetiva pela palpação dolorosa na lateral do quadril, Descrever um teste clínico de irritabilidade dos glúteos, pode melhorar o direcionamento diagnóstico e apresentar novos meios semiológicos de avaliações para resultados terapêuticos desta patologia.
