Evaluation of Functional and Biomechanical Properties of Bone Regenerates

Resumo

Functional tests with incrementing axial load on the affected limb were performed in patients with humerus, tibia and fibula fractures, or undergoing tibial bone lengthening using the Ilizarov apparatus (n = 75). It was found that oossification was associated with a decrease in the blood flow velocity in the arteries of the bone regenerate. In the humerus, the exercise tolerance was two to three times lower, while the micromotion rate of bone fragments and the blood flow velocity were higher. The micromotion rate and the blood flow velocity decreased by the end of the fixation period, since they were no longer affected by the incrementing load.
