Resumen

NATALI, J; WHEELER, J. T; KOHL, R  y  VARELA, P. Compare the Mechanical Statistical Characteristics of Dog Femur Isolet, with or without Placing to an Orthopedic Píate Made of Polypropylene. Int. J. Morphol. [online]. 2008, vol.26, n.4, pp. 791-797. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022008000400001.

The general aims were: to evalúate the resistance to compression of the right fémur isolated and that of the left fémur transversally osteotomized fixed to an orthopedic píate made of polypropylene and to compare the mechanical statistical characteristics between both. This work was carried out by performing an experimental charge pattern made of a mammal fémur (dog) under isolated conditions. Fémur bones of 13 hybrid young adult dogs of médium to large size were used. A servohydric engine was used for the Amsler Wolpert static and dynamic essays. The mean difference statistical test for depending paired samples was used for the evaluation of data. As a result of the curves analysis it was obtained that: before failure the right fémur underwent a charge of 4.02 to 8.47 KN (= 6.66 KN) with a deformation of 2.02 to 5.09 mm (= 3.66mm) while the charge that the left fémur + orthopedic píate underwent before de failure was of 3.05 to 5.61 KN ( = 4.49KN) with a deformation of 2 to 4.5 mm ( = 3mm). As a conclusión it might be stated that there are differences in the resistance to the compressive charge between right fémur and its left contra lateral + the orthopedic píate.
