An overall estimation of the structure and strength properties of lyophilized connective tissue allografts from 73 cadavers of both sexes, aged from 20 to 50, was performed. Criteria for preservation of their fibroarchitectonics depending upon the type of the connective tissue fibrous framework and presence of the main substance were determined. It was shown that lyophilization process was accompanied by changes in architectonics and reduction of strength properties in allografts made of dense formed connective tissue with orientated (Achilles tendon) and mixed (dura mater, broad fascia) type of fibrous framework. A spatial non-orientated type of derma fibrous framework in weight bearing foot segments stipulated preservation of architectonics and plastic properties after lyophilization.
