Kusweka kwa khosi la femur kumachititsa 50% ya kusweka kwa chiuno. Kwa odwala omwe si okalamba omwe ali ndi kusweka kwa khosi la femur, chithandizo cha mkati nthawi zambiri chimalimbikitsidwa. Komabe, mavuto omwe amachitika pambuyo pa opaleshoni, monga kusalumikizana kwa kusweka, kusweka kwa mutu wa femur, ndi kufupika kwa khosi la femur, ndizofala kwambiri m'machitidwe azachipatala. Pakadali pano, kafukufuku wambiri amayang'ana momwe angapewere kusweka kwa mutu wa femur pambuyo pa kusweka kwa khosi la femur, pomwe chisamaliro chochepa chimaperekedwa ku nkhani ya kufupika kwa khosi la femur.
Pakadali pano, njira zomangira mkati mwa khosi la femoral fractures, kuphatikizapo kugwiritsa ntchito zomangira zitatu zomangira, FNS (Femoral Neck System), ndi zomangira za dynamic hip, zonse cholinga chake ndi kupewa femoral neck varus ndikupereka compression axial kuti tipewe kusalumikizana. Komabe, kupsinjika kosalamulirika kapena kopitirira muyeso kumabweretsa kufupikitsa khosi la femoral. Chifukwa cha izi, akatswiri ochokera ku Second People's Hospital Affiliated with Fujian University of Traditional Chinese Medicine, poganizira kufunika kwa kutalika kwa khosi la femoral pakuchiritsa kusweka ndi ntchito ya chiuno, adapereka lingaliro logwiritsa ntchito "chomangira choletsa kufupikitsa" pamodzi ndi FNS pokonza kusweka kwa khosi la femoral. Njirayi yawonetsa zotsatira zabwino, ndipo kafukufukuyu adasindikizidwa mu magazini yaposachedwa ya Orthopaedic Surgery.
Nkhaniyi ikutchula mitundu iwiri ya "zomangira zoletsa kufupikitsa": imodzi ndi screw yokhazikika yopangidwa ndi kannulo ndipo inayo ndi screw yokhala ndi ulusi wawiri. Mwa milandu 53 yomwe ili mgulu la zomangira zoletsa kufupikitsa, milandu 4 yokha ndi yomwe idagwiritsa ntchito screw yopangidwa ndi ulusi wawiri. Izi zikubweretsa funso loti ngati screw yoletsa kufupikitsa pang'ono ilidi ndi mphamvu yoletsa kufupikitsa.
Pamene zomangira zonse ziwiri zokhala ndi ulusi pang'ono ndi zomangira ziwiri zinasanthulidwa pamodzi ndikuyerekezeredwa ndi kukhazikika kwamkati kwa FNS, zotsatira zake zinasonyeza kuti kuchuluka kwa kufupika mu gulu la zomangira zotsutsana ndi kufupika kunali kotsika kwambiri kuposa gulu la FNS lachikhalidwe pa mfundo zotsatila za mwezi umodzi, miyezi itatu, ndi chaka chimodzi, ndi kufunika kwa ziwerengero. Izi zikubweretsa funso lakuti: Kodi zotsatira zake ndi chifukwa cha zomangira zokhazikika kapena zomangira ziwiri?
Nkhaniyi ikupereka milandu 5 yokhudza zomangira zoletsa kufupikitsa, ndipo mutayang'anitsitsa, zitha kuoneka kuti m'milandu 2 ndi 3, pomwe zomangira zolumikizidwa pang'ono zinagwiritsidwa ntchito, panali kubweza ndi kufupikitsa zomangira (zithunzi zolembedwa ndi nambala yomweyi zikugwirizana ndi mlandu womwewo).
Kutengera ndi zithunzi za bokosilo, mphamvu ya screw yokhala ndi ulusi wawiri poletsa kufupikitsa ndi yoonekeratu. Ponena za screws zotsekedwa, nkhaniyi sipereka gulu losiyana loyerekeza. Komabe, nkhaniyi imapereka lingaliro lofunika kwambiri pa kukhazikika kwa mkati mwa khosi la femoral, ndikugogomezera kufunika kosunga kutalika kwa khosi la femoral.
