1.Yintoni i-femoral stalk

Intshayelelo:

Isiqu se-femoral (Isiqu se-Femoral) yinxalenye yecandelo lesinyithi elisetyenziselwa ukubuyisela indawo ephezulu ye-femur yesigulane (ithambo lethanga) kwi-artificial hip replacement surgery. Ngenye yezona zinto zibalulekileyo zenkqubo ye-hip yokwenziwa kwaye inoxanduva lokuxhuma kwintloko ye-femal kunye nokuthatha imithwalo kunye nokunyakaza kwe-joint hip. Indima ephambili ye-femoral stem kukudlulisa ukunyakaza kwe-hip joint kunye nomlenze ophantsi ukuya kuyo yonke i-hip joint hip, ukuqinisekisa ukuba umdibaniso uzinzile, ukhululekile kwaye usebenza ngokufanelekileyo.

Ubume kunye nomsebenzi wesiqu se-femoral

Ubume:

Isiqu se-femoral sivame ukugoba okanye i-cylindrical kwaye yenzelwe ukufanisa imilo ye-anatomical ye-femur yomntu. Ibuyisela umsebenzi we-hip joint ngokutyalwa kwi-femur kunye nokudibanisa kwintloko ye-femoral (enye inxalenye ye-hip joint).

Indima:

Isiqu se-femoral sithwala ubuninzi bobunzima bomzimba obungaphezulu, ngoko ke kufuneka sibe nomthamo owomeleleyo wokuthwala umthwalo kunye nokuzinza. Kufuneka kwakhona i-biocompatible ukuqinisekisa i-osseointegration ngexesha lokusetyenziswa kwexesha elide.

Iintlobo kunye noyilo lweziqu ze-femoral

Iintlobo zesikhondo se-femoral

Kukho iintlobo ezahlukeneyo ze-femoral shanks kwaye eziqhelekileyo ziquka:

I-Round shank:

Ifanele izigulana ezine-anatomy ye-femoral ephantse ibe yingqukuva, kulula ukuyifaka, kodwa isenokungabotshelelwa ngokukhuselekileyo kwezinye izigulana ezineosteoporosis.
Ukongezelela, iingenelo zee-shanks ezijikelezayo ziquka iinkqubo zotyando ezilula kunye namaxesha amancinci okufakelwa. Nangona kunjalo, kufuneka kuqatshelwe ukuba kwizigulane ezine-low bone mineral density okanye i-osteoporosis, ezinye iintlobo ezifanelekileyo ze-femoral stem zingadinga ukuqwalaselwa ukuze kuqinisekiswe ukuzinza kwexesha elide.

I-tapered shank:

Ngokuqhelekileyo isetyenziswa kwizigulane ezine-anatomy ye-femoral tapered ngakumbi kunye ne-tapered okanye encinci ye-femoral stem ukunceda ukukhusela i-femoral stem.

Amanqina ahlengahlengiswayo:

Amanye amanqina eefemoral ayilwe aneempawu ezilungelelanisiweyo ezinokulungelelaniswa nomzimba wesigulana.

Amanqina aqhubela phambili:

Ezi shank zenzelwe ukubonelela ngemigangatho eyahlukeneyo yokuzinza kunye nokusabalalisa umthwalo ukulungiselela iimpawu ezahlukeneyo zamathambo kunye neemfuno zesigulane.

Amanqina e-Femoral aneetyali:

Okufana ne-cemented okanye i-cementless (oko kukuthi, i-osseointegrated), kuxhomekeke kumgangatho wethambo lesigulana kunye nesakhiwo se-femal. Inguqulo ye-cemented ifanelekile kwizigulane ezindala, ngelixa i-osseointegrated version ifanelekile kwizigulane ezinomgangatho ongcono wamathambo.

Uyilo lwesiqu se-femoral ngokuqhelekileyo lubandakanya:

Ukuqwalaselwa kwe-anatomical adaptations, njenge-engile, ubude, kunye nokugoba kwesiqu se-femoral. Ukhetho lwenziwa ukuqinisekisa ukuba i-femoral stem yenza unxibelelwano oluhle kunye ne-femur kwaye ihlala izinzile.
Uyilo oluhlengahlengiswayo: Ezinye iziqu ze-femoral ziyilelwe kunye neempawu ezilungelelanisiweyo ezivumela uhlengahlengiso oluthile lwenziwe ngexesha lotyando ukuziqhelanisa nezakhiwo ezahlukeneyo ze-anatomical.
