Análise comparativa em modelo computadorizado bidimensional com simulação do emprego de hastes flexíveis de aço e titânio, na fratura do fêmur da criança, utilizando o método dos elementos finitos

Relationship Between Rigidity of External Fixator and Number of Pins: Computer Analysis Using Finite Elements

“…Since then, several other studies have been conducted 6 , 7 , 8 , 9 , 10 , 11 . Studies using this technique have also been published in the Brazilian literature, but not with simulation of an external fixator 12 , 13 , 14 .…”

Relação entre rigidez de fixador externo e quantidade de pinos: análise computacional por elementos finitos

“…Since then, several other studies have been conducted (6)(7)(8)(9)(10)(11) . Studies using this technique have also been published in the Brazilian literature, but not with simulation of an external fixator (12)(13)(14) . The commercial finite-element packages available are very versatile tools for evaluating the influence of A B C assembly parameters in relation to the axial stiffness of a particular external fixator, because of the ease of modifying the geometrical characteristics of the assembly and outline conditions of the model.…”

Osteosynthesis With Intramedullary Nails in Children

“…In Brazil, Soni et al . (4) presented a two-dimensional computer model, simulating a fracture of the femur in children treated with flexible steel and titanium nails, comparatively assessing the stress distribution. They concluded that the biomechanical behavior was qualitatively better in the model with titanium nails.…”

“…Nonunion or delayed union are uncommon and when they occur, it seems to be related to the inappropriate use of surgical techniques. Complications are limited to the skin or discomfort at the site of nail insertion 1 , 2 , 3 , 4 , 5 . Changes in bone length due to growth disturbances appear to be minimal, with an average of overgrowth of the femur of about 1.2 mm (12) .…”
