Comparative study of two plastic materials, i.e. frozen cortical allobone and demineralized perforated allobone (perfoost) was performed. Testing of the samples from the same part of the tibia was carried out using Zwick 1464 apparatus. It was showed that firmness of perfoost was lower than that of the frozen allobone: during compression - by 33%, switching - by 66%, bending - by 46% for metaphyseal sample and by 70% for diaphyseal one. Perfoost possesses the rigidity that allows to use this graft in marginal resection as well as in osteotomy as a bone fixator. Advisability of the graft in segmental resection of lower extremity without cortical allograft is doubtful.
