Cementless femoral stem ya hip prothesis,
Uruti rwigitsina gore, uruti rw'umugore, ikibuno,

Ibicuruzwa bireba

Ihuriro ryibibuno rigizwe na sock, umurongo, umutwe wumupira, ikiganza nibindi bice. Buri kintu kigira ibikoresho byinshi nibisobanuro. Guhitamo ibikoresho nicyitegererezo ukurikije kubaga ikibuno gitandukanye. Hariho ubwoko bubiri bwibiti: ibiti bya sima na bio-bifatanye. Igiti cyibinyabuzima ubu dukoresha kwisi yose nigishushanyo cyibice bitatu-bishushanyije, bikoreshwa mukuzamura ihererekanyabubasha no kunoza ituze ryinyuma yinyuma. Igishushanyo mbonera cyibiti byongerewe imbaraga byongera ituze ryumutwe wumupira, kandi ijosi risennye cyane ryanonosowe kugirango ryongere urwego rwimikorere ya protezi. Urusenda rwegeranye ni perpendicular yerekeza ku cyerekezo cyo gutwara imihangayiko, ifasha osseointegration yihuse kandi ituje neza. Ubuso bwumubiri wuruti rwuzuye neza hamwe na plasma titanium slurry, kandi igipfundikizo kibyara gifasha gukura amagufwa kandi ikabona ingaruka nziza zigihe kirekire. Imbere n'inyuma y'uruhande rw'imbere ya rasp itanga itangazamakuru ryiza rihuye n'amagufwa ya kanseri, kongera ubuso bwo guhuza hagati ya protezi n'amagufwa, kandi bigatanga uburyo bwiza bwo gufunga uruti kugirango uruti rurohama. Ijosi n'ibirenge byumye ni dogere 135. Irashobora kandi kuba ibicuruzwa bidasanzwe kuburyo bwa DAA. Ibyiza byayo nuburyo nyabwo bwimitsi, bufite igihe gito cyo gukira, igihe gito cyo gukira imyitozo ya buri munsi, kugabanya ububabare bwabarwayi, kugabanya igihe cyo gushyirwa mubitaro, no kugabanya ibyago byo kwimurwa. Prothèse femorale ivurwa no kogosha ibitugu kugirango ibungabunge amagufwa ya trochanter nini, ikwiranye no gutera DAA byibuze. Impera yegeranye yimibiri yumubiri irabyimbye, impera ya kure iragufi, kandi igishushanyo mbonera kigufi cyerekana umutekano kandi cyoroshya gushyirwaho.
Ubuso bunini cyane bwo hejuru bwurwego rwa sima bufite sima nziza cyane, bukurikiza inyigisho zisanzwe zirohama, butuma prothèse irohama gato mumasima ya sima, kandi ikozwe nuburinganire bwa mpandeshatu kugirango igabanye stress ya sima. Bifite ibikoresho byacometse kure hamwe nuwinjizamo kugirango umenye neza ko prothèse ihagaze neza mumuyoboro wa medullary. Inguni y'uruti rwe ni dogere 130. Gereranya impagarike nyayo yibibero kurwego runini.
Kugeza ubu, ubuso bwicyuma gikoreshwa cyane hamwe na vacuum plasma titanium slurry. Ipitingi isukuye ifasha amagufwa no kumara igihe kirekire. Igishushanyo mbonera cyiza cyongera ituze ryigikombe hamwe nimbere. Dutanga kandi socket zitandukanye. Guhitamo umurongo ujyanye nibyifuzo byabarwayi batandukanye.
Umutwe wumupira ufite umutwe wumupira wumubumbyi, kandi umutwe wumupira wicyuma urahari. Umupira wumupira wumubumbyi nigisekuru cya kane cyibikoresho bya ceramic BIOLOXdelta yibikoresho, bifite biocompatibilité nziza, ibintu byiza byo kuzenguruka no gusiga amavuta, kwambara ultra-hasi, kandi bihujwe rwose na taper yikibabi cya zahabu. Umutwe wumupira wicyuma ukozwe muri cobalt-chromium-molybdenum hamwe nubuhanga buhanitse bwo hejuru.
Ubuso bwumutwe wa bipolar ukoreshwa mugusimbuza hemi-hip wasizwe neza, hamwe na coefficient nkeya cyane yo guterana. Igishushanyo mbonera-cyerekana uburyo ntarengwa bwo kugenda bwikibuno kandi kigabanya igipimo cyo kwambara. Igishushanyo mbonera kinini-gifunga igishushanyo gifite imikorere myiza yo kurwanya dislokisiyo. Ibisobanuro bitandukanye byiki gicuruzwa birahari kubaganga bahitamo bakurikije imiterere itandukanye yumurwayi, ibyo bikaba bifasha umurwayi gukira hakiri kare.
