A csont mikrokeringési változásainak kísérletes vizsgálati lehetőségei

Absztrakt Bevezetes/Celkitűzes: Kiserleteink celja a periosteum mikrokeringesi valtozasainak felterkepezese, valamint a velőűrfelfuras altal okozott periostealis mikroer-reakciok modellezese, időbeli valtozasuk megismerese volt. Tovabbi vizsgalatainkban jellemeztuk es osszehasonlitottuk a human csipőizuleti endoprotetikaban hasznalatos anyagok mikrokeringesi hatasait a csonthartyaban. Anyag es modszer: Him Wistar-patkanyok jobb oldali tibiajaba endomedullaris titan-, acelotvozet, illetve polietilen implantatumot helyeztunk mikrosebeszeti modszerrel. Intravitalis videomikroszkop segitsegevel vizsgaltuk a tibia anteromedialis es anterolateralis felszinen a periosteum erstrukturajat (ossz-erdenzitas, kapillarisok aranya), valamint mikroszkopos mechanikai teszt segitsegevel az implantatumok stabilitasat. Kontrollcsoportban vizsgaltuk a velőűrfelfuras hatasat a periostealis erstruktura valtozasaira a műtet utan 6 es 12 hettel. Eredmenyek: A velőűr felfurasa onmagaban szignifikansan novelte az anteromedialis pe...
