Step by step endoprostheses replacement technique in children with bone tumors of knee joint

Background. To define perspective directions in the decision of the basic questions of modular endoprostheses replacement in the treatment of children with bone tumors of knee joint on the basis of experimental researches. Methods. Study was conducted on 35 white ratsmales 3 month old (live weight 190210г.). The analysis was based on the first experience of our children’s clinic - 4 pts with primary bone tumors who underwent modular endoprostheses replacement with spacerendoprostheses at treatment stages. Results. By month 5 after surgery all animals had restriction of movements in the operated joint and shorting of extremity Animals operated on one segment had interfacing segment longer and similar to non operated extremity. The analysis of a clinical data showed, that the less extremity shorting was observed in pts with unipolar endoprostheses replacement. Conclusion. From all variety of methods of surgical treatment the most modern and perspective is individual modular endoprostheses replacement. The technique step by step endoprostheses replacement possesses advantages. The received results allow to consider its effective and perspective for further use.
