[Biomechanical study on bone grafts harvested from cadavers].

Today the technique of free revascularized bone grafts in reconstruction surgery of the head and neck has been well developed. The grafts can be harvested from different parts of the body. No data have been found regarding biomechanics of different grafts. The authors examined 18 samples of cadaver iliac crest, radius, lateral edge and spine of scapula and fibula, respectively, and 6 samples of mandible. The study pointed out that the stiffness of the fibula approached those of mandible. The stiffness of the other bone grafts were found much smaller.
