"In the present study the in vitro tensile properties of the porcine extensor digitorum profundus tendons were obtained. For a measurement the testing system MTS Mini Bionix 858.2 was used. Data were obtained from displacement of jaws and with an extensometer. Data from displacement of jaws are influenced of slip specimens from jaws. The problem of the tendon sidle out of the jaws was solved. For the better fixation of tendon in jaws during tensile tests the new profile of jaws component were developed. Next innovation in tendon fixing comes with the cooling the tendon ends by liquid nitrogen before clamping. With the measuring setup with frozen ends and jagged rounded profile of jaws can be obtained satisfactory strain data without using of an extensometer." . "Acta Mechanica Slovaca" . .
