The Hip

Level III involves the creation of biokompozitsionnyh containing materials as the main components of bone and bioactive substances. The latter include growth factors, morphogenetic proteins and other components of the bone matrix. Bioactive substances assigned the role of activators and regulators physiological tissue regeneration. In addition, at the stage of implantation in the composition of such materials can be included, and a variety of transplanted progenitor cells. Currently, the creation of biokompozitsionnyh materials in Russia has become a priority 3. Recently active development and technological level IV, characterized by the creation of synthetic materials biokompozitsionnyh based on modern technology.

The latter include steriolitograficheskoe up tissues 4, the technology of 3-D implants 5,6, liquid-distributing simulation 7 and the creation fazovoizmenyayuschee implants 8. Connection these methods with high accuracy to copy objects and fabric to create materials with well-defined size, geometry and distribution of pores, as well as fully play architecture of the organ site and its internal channels in the created implant. Unfortunately, soon put into practice a Russian textile banks such technologies is not possible for many reasons. In the presence of specific technical capabilities and their own experience, in a tissue bank CITO over the last ten years have been developed and introduced into medical practice in a number of new bioplastic materials second and third technological levels. First of all, it's – 'Perfoost', which is a freeze-dried demineralized bone alloimplantaty (DKI), made in the form of sheets, shavings, chips, etc.

Different degrees of demineralization and geometry data have allowed bioplastic materials to use it in many areas of reconstructive surgery is to fill in any bone defects and to accelerate the process of bone formation 9,10. For practical Medicine CITO Bank DKI have also been proposed, made from the bones of the cranial vault. Due to their large size and high degree of demineralization of this material is now widely used in orthopedics at conduct an audit replacement for the replacement of major defects of the bottom wall of the acetabulum and the hip.
