Uma kukhulunywa ngokuhlinzwa kokufakwa esikhundleni sezinqe,ikhanda lesifazanekwei-prosthesis yesinqeingenye yezingxenye ezibaluleke kakhulu. Idlala indima ebalulekile ekubuyiseleni ukunyakaza kanye nokuqeda ubuhlungu beziguli ezinezifo zamalunga ezinqeni njenge-osteoarthritis noma i-avascular necrosis yekhanda le-femoral.
Kunezinhlobo ezahlukene zamakhanda e-femoral okufakelwayo wesinqe ongawakhetha, ngalinye lenzelwe ukuhlangabezana nezidingo ezithile zesiguli kanye nokucatshangelwa kokwakheka komzimba.Izinto ezivame kakhulu yinsimbi, i-ceramic kanye ne-polyethylene.
Ikhanda le-femoral lensimbingokuvamile yenziwe ngama-alloy e-cobalt-chromium noma e-titanium futhi aziwa ngokuqina kwawo nokuqina kwawo. Ngokuvamile asetshenziswa ezigulini ezisencane, ezisebenzayo ezidinga ikhambi eliqinile elingamelana namazinga aphezulu omsebenzi.
Amakhanda e-Ceramic femoralNgakolunye uhlangothi, ziyathandwa ngenxa yezinga lazo eliphansi lokugugulekakanye nokuhambisana kwezinto eziphilayo. Azinawo amathuba amaningi okubangela ukusabela kokungezwani komzimba, okwenza kube ukukhetha okuhle kweziguli ezinesifo sokuzwela kwensimbi. Ngaphezu kwalokho, amakhanda e-ceramic femoral anikeza ubuso obubushelelezi bamalunga, okunciphisa ukungqubuzana nokuguguleka.
Amakhanda e-femoral e-polyethylenengokuvamile zisetshenziswa kanye nezingxenye zensimbi noma ze-ceramic. Zenzelwe ukuhlinzeka nge-cushion futhi ngokuvamile zingabizi kakhulu. Kodwa-ke, uma kuqhathaniswa nezingxenye zensimbi noma ze-ceramic, zingaguga ngokushesha, okwenza zingafaneleki kakhulu ezigulini ezisencane nezisebenzayo.
Ngamafuphi, ukukhethainquluilungaikhanda le-femoral lokufakelwaKubalulekile empumelelweni yokuhlinzwa kokufakelwa inqulu. Ukuqonda izinhlobo ezahlukene zamakhanda e-femoral—insimbi, i-ceramic, i-polyethylene, kanye ne-hybrid—kungasiza iziguli nabahlinzeki bezempilo ukuthi benze izinqumo ezinolwazi ngokusekelwe ezidingweni zabo kanye nendlela yabo yokuphila.
