DALLABRIDA, Ademar Luiz et al. Biomechanical analisis ex vivo of two osteosynthesis methods for transversal diaphiseal fracture in canine femur. Cienc. Rural [online]. 2005, vol.35, n.1, pp.116-120. ISSN 0103-8478.

The aim of this study was to compare ex vivo, in 12 pars of bone, the axial compression and bending strength of two transversal diaphiseal fracture reducing devices in canine femur of dogs weighting 5 to 10kg. One method using two intramedullary pins of Steinmann 2.0mm diameter, and the other using cortical internal transfixator with two intramedullary pins of Steinmann 2.0mm diameter, which posteriorly turned-up around the bone like a splint and fixed with surgeon wire cerclage 0.6mm diameter, to fix them. The fractured and stabilized bones, after the fragments reduction, were put on test under the strength of a Soloteste® press, where the ones from group G2 (internal skelethic transfixation) presented a statistically significant superiority of the fixation device stiffness in relation to those from group G1 (intramedullary pin).
