Kumvetsetsa Mitundu ya Mitu Yachikazi mu Ma prostheses a Hip

Pankhani ya opaleshoni yobwezeretsa m'chiuno, themutu wachikazichaprosthesis ya m'chiunondi chimodzi mwa zigawo zofunika kwambiri. Zimagwira ntchito yofunika kwambiri pobwezeretsa kuyenda komanso kuchepetsa ululu kwa odwala omwe ali ndi matenda olowa m'chiuno monga osteoarthritis kapena avascular necrosis yamutu wa chikazi.

Pali mitundu yosiyanasiyana ya hip prosthesis femoral mutu wosankha, iliyonse yopangidwa kuti ikwaniritse zosowa za odwala komanso malingaliro a anatomical.Zomwe zimagwiritsidwa ntchito kwambiri ndi zitsulo, ceramic ndi polyethylene.

Chitsulo femoral mutunthawi zambiri amapangidwa ndi cobalt-chromium kapena titaniyamu aloyi ndipo amadziwika chifukwa chokhalitsa komanso mphamvu. Amagwiritsidwa ntchito kwa odwala achichepere, omwe amafunikira njira yolimba yomwe imatha kupirira ntchito zapamwamba.

Mitu ya Ceramic Femoral, kumbali ina, amakondedwa chifukwa cha kavalidwe kawo kakang'onondi biocompatibility. Sangathe kuyambitsa kuyabwa, kuwapanga kukhala chisankho choyenera kwa odwala omwe ali ndi vuto lachitsulo. Kuphatikiza apo, mitu ya femoral ya ceramic imapereka malo olumikizana bwino, kuchepetsa mikangano ndi kuvala.

Polyethylene femoral mutuNthawi zambiri amagwiritsidwa ntchito limodzi ndi zitsulo kapena zida za ceramic. Amapangidwa kuti azipereka cushioning ndipo nthawi zambiri amakhala okwera mtengo. Komabe, poyerekeza ndi zitsulo kapena zitsulo za ceramic, zimatha kutha mofulumira, zomwe zimapangitsa kuti zikhale zosayenerera kwa odwala aang'ono komanso okhudzidwa kwambiri.

Mwachidule, kusankha kwachiunopamodziprosthesis mutu wachikazindizofunikira kuti opaleshoni yobwezeretsa ntchafu ikhale yabwino. Kumvetsetsa mitundu yosiyanasiyana ya mitu yachikazi-zitsulo, ceramic, polyethylene, ndi hybrid-kungathandize odwala ndi opereka chithandizo chamankhwala kupanga zisankho zoyenera malinga ndi zosowa zawo ndi moyo wawo.
