Improved testing procedures to assess the physical and mechanical properties of...
Freire,Ailton; Parsekian,Guilherme; Baptista,Adriana; Fonseca,FernandoABSTRACT In Brazil, ceramic blocks have a significant share of the masonry construction market. Thus, an experimental testing program was devised to determine the physical and mechanical properties of ceramic blocks from different regions of Brazil. The experimental program included blocks from five Brazilian states and ten different producers, and the properties studied were absorption, material density, efflo...
Study on Overload Injuries during Periods of Intense Physical Activity Compleme...
Mónico,José Lito; Silva,Frederico; Marques,José Pedro; Cardoso,Joaquim; Mónico,Lisete; Fonseca,FernandoAbstract Objective The present study aims to measure the incidence of overload injuries in training soldiers, who are subjected to intense physical exercise, and to compare it with a control group. Next, it intends to verify whether there is any relationship between overload injuries and some neuromuscular function parameters. Methods Analytical, prospective observational study. Both the observational and the c...
Biomechanical Evidence on Anterior Cruciate Ligament Reconstruction
Completo,António; Noronha,José Carlos; Oliveira,Carlos; Fonseca,FernandoAbstract Objective Anterior cruciate ligament (ACL) reconstruction is recommended in athletes with high physical demands. Several techniques are used in reconstruction; however, themost relevant question still is the best biomechanical positioning for the graft. The present study aimed to analyze the biomechanical effect of the position of bone tunnels on load distribution and joint kinetics, as well as the med...
Allograft of the knee extensor in cases of patellar tendon rupture in total art...
Fonseca,FernandoABSTRACT Objective: Retrospective study to evaluate the functional results of patients with total knee arthroplasty and rupture of the patellar tendon, submitted to transplantation of the extensor knee apparatus with fresh frozen allograft. Method: Nine patients, operated between 2003 and 2015, with a minimum of one year of follow-up. All patients were reviewed by performing a functional evaluation using the Kn...
Doença de Camurati-Engelman: A propósito de um caso clínico
Santos,Sandra; Pinheiro,Vítor Hugo; Pinto,André; Carvalho,Marcos; Lopes,António Pais; Fonseca,FernandoObjetivo: O presente caso clínico tem como objetivo apresentar o tratamento, resultado clínico e imagiológico de uma lesão traumática (fratura supracondiliana do fémur) num doente com doença de Camurati-Engelmann, doença displásica óssea que produz deformidade hiperostótica da diáfise dos ossos longos. A doença de Camurati-Engelmann é uma doença genética autossómica dominante rara, de prevalência desconhecida N...
Total bilateral ruptures of the knee extensor apparatus
Moura,Diogo Lino; Marques,José Pedro; Pinheiro,João Páscoa; Fonseca,FernandoABSTRACT OBJECTIVE: Bilateral extensor tendon ruptures of the knee are rare and have only been published in the form of case reports or small series. METHODS: Seven patients corresponding to 14 extensor tendon ruptures of the knee were evaluated by the same examiner after a minimum one year post-surgery. Clinical and radiographic evaluations were performed; for statistical analysis, the level of significance wa...
Fratura de Hahn-Steinthal: A propósito de um caso clínico
Fontoura,Ugo; Nascimento,Miguel; Carvalho,Marcos; Gomes,Armando; Gaspar,Rita; Dias,Madeira; Fonseca,FernandoIntrodução: As fraturas isoladas do capitellum são lesões raras, representando menos de 1% das fraturas a nível do cotovelo e 6% das fraturas do úmero. Ocorrem geralmente em adolescentes, na maioria dos casos depois dos 12 anos de idade. Este padrão de fratura foi descrito pela primeira vez em 1853 por Hahn; posteriormente, Kocher em 1896, Steinthal em 1898 e Lorenz em 1905 descreveram diferentes padrões para e...
Menisco discóide: Controvérsias do tratamento
Moura,Diogo; Marques,Pedro; Fonseca,FernandoO menisco discóide é a denominação para uma variante anatómica anormal dos meniscos dos joelhos, que é frequentemente assintomática. A morfologia e por vezes a instabilidade do menisco discóide são responsáveis pelo seu risco aumentado de roturas e lesões degenerativas, que podem causar sintomas. Uma avaliação clínica adequada combinada com uma ressonância magnética nuclear do joelho são essenciais para um diag...
Environmental factors can influence dengue reported cases
Carneiro,Marco Antonio F.; Alves,Beatriz da C. A.; Gehrke,Flávia de Sousa; Domingues,José Nuno; Sá,Nelson; Paixão,Susana; Figueiredo,João; Ferreira,AnaSummary Introduction: Global climate changes directly affect the natural environment and contribute to an increase in the transmission of diseases by vectors. Among these diseases, dengue is at the top of the list. The aim of our study was to understand the consequences of temporal variability of air temperature in the occurrence of dengue in an area comprising seven municipalities of the Greater São Paulo. Met...
Total ruptures of the extensor apparatus of the knee
Moura,Diogo; Fonseca,FernandoABSTRACT OBJECTIVE: This was a retrospective case-control study on total ruptures of the extensor apparatus of the knee, aimed to compare patella fractures with tendinous ruptures. METHODS: The sample included 190 patients and 198 total ruptures of the knee extensor apparatus. All patients were evaluated by the same examiner after a minimum one-year follow-up. RESULTS: Tendinous ruptures occurred most frequentl...
