[New results on the genesis of traumatic Achilles tendon rupture].

As a result of the development of a new fixing mechanism, which permitted the test of peak value of tensile strength in Achilles tendons, the following facts were demonstrated: 1. The average value of static maximum of tensile strength is about 7, 5 kp/mm2, of the dynamic maximum is about 10, 1 kp/mm2. 2. The charge maximum decreases with progressive age. 3. The tensile strength depends on the minimal cross-section plane of the tendon. 4. The minimal cross section plane decreases with progressive age. 5. With the test of dynamic tensile strength it is possible to malinger a Achilles tendon rupture.
