Tihonenko A. Forearm bones deformity correction in some tumor and dysplastic cases by rod apparatus in childrenўs.

3. Object of research - processes of correction and regeneration of forearms bones with deformities and short-enings from the tumor and displastik injuries. Methods of research - clinical research (anamnesis, patiens exsamination, morfofunctional features forearms and wrist, neurological research). Radiological analysis of variants of development of deformities. Gistological re-searh of tumor and displastik tissues. Biomechanical re-searches of stability rod systems of the external fixators; New knowledge: for the first time requirements to rod systems for treatment of deformities and shortenings from the tumor and displastik injuries in childrenўs. The thesis deals with corrections of deformities and shortenings of forearms bones with tumor and displastik injuries. A rod apparatus for external fixation of the author's design was used. The analysis of biomechanical and clinical investiga-tions demonstrates of advantages the using of rod appara-tus above the Ilizarov?s apparatus. 18 patients with deformities and shortenings of fore-arms bones were treated by rod apparatus for external fixation (39 operation). The obtained results make it possi-ble draw a conclusion about advantages of rod apparatus for corrections of shortening and deformations of forearm bones with tumor and displastik injuries in children's. Re-sults of research are intpinuced into clinical practice: emergency hospital and regional children's hospital of Nikolaev; city emergency hospital of Simferopol; ortho-paedic and traumatology unit of Volynsk regional chil-dren's territorial associations (Lutsk); children's orthopae-dic sanatorium named after N.K.Krupskaya (Evpatoria).
