Osteosynthesis ya chikazi ndi njira yomwe mafupa amathandizira. Zimapereka mphamvu zowonongeka kwa zidutswa zogwirizana, kufikira zitakwanira. Njira yamankhwalayi imakhala mkati, pamene zipangizo zosiyanasiyana zimagwiritsidwa ntchito mkati mwa thupi la wodwala, ndi kunja, momwe zimagwiritsira ntchito zipangizo zolepheretsa kusokoneza zakunja.
Zizindikiro za osteosynthesis ya chikazi
Osteosynthesis ya femur ndi chipangizo cha mkati kapena chipangizo chosokoneza-chipangizo chikuwonetsedwa pamene:
- zophulika zomwe sizingagwirizane popanda kugwiritsanso ntchito kwa zinyansi;
- Ziphuphu zimaphatikizapo kuwonongeka kwa mitsempha kapena thunthu kapena kutengako mbali zofewa;
- Mitsempha, yomwe imakhala ndi ngozi yowonongeka khungu ndi fupa la fupa.
Mitundu ya osteosynthesis ya chikazi
Mitundu yayikulu ya osteosynthesis ya chikazi ndi:
- Intramedullary osteosynthesis ya femur ndi mankhwala omwe amathyolapo mapepala omwe amakhala ndi mapepala omwe ali ndi mapulogalamu omwe amatha kumapeto. Kupyolera mu mabowo, zikopa zimayikidwa kudzera mwa fupa lovulala ndikukonzekera zidutswazo. Ubwino wa njira imeneyi ndi kupsyinjika kwake, komanso kuthana ndi chiwalo chodwala masiku angapo mutatha kuika.
- Matenda osteosynthesis - amachitidwa mothandizidwa ndi mbale za miyeso yosiyanasiyana. Amapanga mabowo omwe amagwirizana ndi mafupa a fupa. Zomwe zatchulidwa posachedwapa mu njira ya chithandizochi ndi mbale zomwe zimakhala zolimba komanso zozizwitsa. Kuwonjezera pa kulumikiza pa screw, iwo ali ndi ulusi mu mutu wodula ndi mu mabowo. Chifukwa cha izi, atatha kugwira ntchito ya osteosynthesis ya chikazi, palibe malo omwe mbaleyo idzagwada.
- Osteosynthesis ndi zipangizo zakunja - kupyolera mu fupa, ndodo kapena spokes, zomwe zimakhala pamwamba pa khungu. Amapereka makonzedwe abwino a mafupa, ndi kukonzanso pambuyo poti mtundu uwu wa osteosynthesis wa chikazi umapita mofulumira komanso mopweteka.
