Abstract
The device relates to reconstructive surgery and orthopedics, and includes a central rod introducible into medullary canals of bone fragments of a bone, and a tubular element fittable on the rod at the place of the missing portion of the bone, the tubular element being equidimensional with the missing portion of the bone. The tubular element is shaped as a shell made of biocompatible polymers, and a layer of a porous polymer material is insertable between the rod and the shell incorporating a biomass of homogenized bone tissues. The invention is used for restoration of missing portions of bone which have been lost due to extensive injuries or wounds or as a result of pathologic changes of the bone tissue (such as may be caused by tumors or tuberculous infections).
