Uma kukhulunywa ngokuhlinzwa esikhundleni se-hip, i-ikhanda lesifazanekwei-hip prosthesisingenye yezingxenye ezibaluleke kakhulu. Idlala indima ebalulekile ekubuyiseleni ukuhamba kanye nokukhulula ubuhlungu ezigulini ezinezifo ezihlangene ze-hip njenge-osteoarthritis noma i-avascular necrosis yekhanda lesifazane.
Kunezinhlobo ezahlukene ze-hip prosthesis femoral heads for choice, ngayinye yakhelwe ukuhlangabezana nezidingo ezithile zesiguli kanye nokucatshangelwa kwe-anatomical.Izinto ezivame kakhulu ziyinsimbi, i-ceramic ne-polyethylene.
Ikhanda lensimbi lesifazanengokuvamile yenziwe nge-cobalt-chromium noma i-titanium alloys futhi aziwa ngokuqina namandla awo. Ngokuvamile zisetshenziswa ezigulini ezincane, ezikhuthele kakhulu ezidinga isisombululo esiqinile esingamelana namazinga aphezulu omsebenzi.
Amakhanda e-Ceramic femoral, ngakolunye uhlangothi, bathandwa ngezinga labo eliphansi lokugqokakanye ne-biocompatibility. Amathuba amancane okuthi abangele ukungezwani komzimba, okuwenza abe yinketho ekahle ezigulini ezinokuzwela kwensimbi. Ngaphezu kwalokho, amakhanda e-ceramic femoral ahlinzeka ngokuhlangana okushelelayo, okunciphisa ukungqubuzana nokuguga.
Polyethylene femoral amakhandangokuvamile asetshenziswa ngokuhambisana nensimbi noma izingxenye ze-ceramic. Zenzelwe ukuhlinzeka nge-cushioning futhi ngokuvamile zibiza kakhulu. Kodwa-ke, uma kuqhathaniswa nezingxenye zensimbi noma ze-ceramic, zingase ziguge ngokushesha, zizenze zingalungeli kakhulu iziguli ezincane nezisebenzayo.
Kafushane, ukukhetha kwehipokuhlangenei-prosthesis yekhanda lesifazanekubalulekile empumelelweni yokuhlinzwa esikhundleni se-hip. Ukuqonda izinhlobo ezihlukahlukene zamakhanda abesifazane—insimbi, i-ceramic, i-polyethylene, ne-hybrid—kungasiza iziguli nabahlinzeki bezempilo benze izinqumo ezinolwazi ngokusekelwe ezidingweni zabo ngabanye nezindlela zokuphila.
