I-Cancellous Screw: Uhlolojikelele Lokusetshenziswa, Izinkomba, Namasu
Isingeniso
Izikulufu zeCancellous ziwuhlobo lwesikulufu samathambo esisetshenziselwa ukulungisa izingcezu zamathambo noma amagrafti ekwelapheni ukuphuka, okungezona izinyunyana, nokunye ukulimala kwamathambo. Lezi zikulufu zisetshenziswa kakhulu ekuhlinzeni amathambo ngenxa yokuhambisana kwazo ne-biocompatibility, ukushutheka kalula, kanye nezakhiwo ezinhle kakhulu zemishini. Kulesi sihloko, sizoxoxa ngezinkomba, amasu, kanye nemiphumela yokusebenzisa izikulufu zokukhansela ekuhlinzeni amathambo.
I-Anatomy kanye Nezakhiwo Zemishini Ye-Cancellous Screw
Izikulufu zeCancellous zenziwe nge-titanium noma insimbi engagqwali futhi zine-shaft enentambo kanye nethiphu ecijile. Imicu ekushafti ihlinzeka ngokuthenga okuhle kakhulu ethanjeni elikhansela futhi ivimbela ukuphuma, kuyilapho ithiphu ecijile yenza kube lula ukufakwa ngaphandle kokulimaza izicubu ezizungezile. Izikulufu ziza ngosayizi nobude obuhlukene ukuze zithwale osayizi abahlukene bamathambo namaphethini okuphuka. Izici zomshini zezikulufu ezikhanselwayo zincike kokubalulekile, ububanzi, ubude, kanye nomklamo wentambo. Ukusetshenziswa kobubanzi obukhulu nezikulufu ezinde kukhulisa amandla okubamba nokuzinza, kuyilapho ukusetshenziswa kobubanzi obuncane nezikulufu ezimfishane kunciphisa ingcuphe yokubhoboza ngokweqile nokuhamba ngezikulufu.
Izinkomba Zokulungiswa Kwesikulufa SeCancellous
Izikulufu ze-Cancellous zikhonjiswe izimo ezihlukahlukene zamathambo, okuhlanganisa:
Ukuphuka kwamathambo amade, njenge-femur, i-tibia, ne-humerus
Ukuphuka kwamathambo amancane, njengesihlakala, iqakala, nonyawo
Okungezona izinyunyana kanye nezinyunyana ezibambezelekile zokuqhekeka
Ama-osteotomies, njengokusikeka kwamathambo okulungisa ukukhubazeka noma ukungalungi kahle
I-Arthrodesis, njengokuhlanganiswa kweqakala, isihlakala, noma umgogodla
Ukulungiswa kokuxhunyelelwa kwethambo, njengokuhlangana komgogodla noma ukwakhiwa kabusha kokukhubazeka kwethambo
Amasu Okulungisa Isikulufu sokukhansela
Indlela yokulungisa isikulufu esikhansele incike kunkomba ethile kanye nephethini yokuphuka. Izimiso ezijwayelekile zokufakwa kwesikulufa zihlanganisa:
Ukuma kahle kwesiguli kanye nokuhlonza indawo yokuphuka
Ukwakhiwa kwembobo yokuhlola kusetshenziswa i-drill bit noma umpompi
Isilinganiso sobude nobubanzi besikulufu
Ukufakwa kwesikulufu kusetshenziswa i-screwdriver noma i-power drill
Ukuqinisekisa indawo yesikulufu nokujula kusetshenziswa izindlela zokuthwebula, ezifana ne-fluoroscopy noma i-X-ray
Izici ezibalulekile ezithinta impumelelo yokulungiswa kwesikulufu esikhanselwayo zifaka ukuqondisa kahle kwezingcezu zokuphuka, ukuncishiswa okwanele kokuphuka, ukubekwa kwesikulufu esifanele nobude, kanye nokuqina okufanele kwesikulufu. Izinkinga zokulungiswa kwezikulufu ezikhanselwayo zihlanganisa ukuxegiswa kwesikulufu, ukuphuka kwezikulufu, ukuthuthwa kwezikulufu, ukungahlangani, i-malunion, ukutheleleka, kanye nokulimala kwenzwa noma umkhumbi.
Imiphumela Yokulungiswa Kwesikulufa KweCancellous
Imiphumela yokulungiswa kwesikulufu sokukhansela incike kunkomba ethile kanye nezici zesiguli, ezifana neminyaka yobudala, izifo ezihambisanayo, nesimo sokubhema. Ngokuvamile, ukulungiswa kwesikulufa sokukhansela kunikeza ukuzinza okuhle kakhulu nokucindezelwa kwezingcezu zokuphuka, okuholela ekuphulukisweni kwamathambo okusheshayo nokubuyiselwa komsebenzi ojwayelekile. Izinga lempumelelo lokulungiswa kwezikulufu zokukhansela lisukela ku-80% ukuya ku-95%, kuye ngenkomba nephethini yokuphuka. Izinkinga zokulungisa izikulufu ezikhanselwayo zingaholela emiphumeleni empofu, njengokulibaziseka ukuphulukiswa, okungahlangene, nobuhlungu obungapheli.
Isiphetho
Izikulufu zeCancellous ziyithuluzi elisebenza ngezindlela eziningi nelisebenzayo ekuhlinzeni amathambo ukuze kulungiswe ukuphuka kwamathambo, ukuxhunyelelwa, kanye nokuhlanganisa. Ukusetshenziswa okufanele kwezikulufu zokukhansela kudinga ukuqonda okuphelele kwe-anatomy, izinkomba, amasu, kanye nemiphumela yenqubo. Ukukhethwa kosayizi wesikulufa esifanele, ubude, nendlela yokufaka kufanele kuhambisane nephethini ethile yokuphuka kanye nezici zesiguli. Ukusetshenziswa kwezikulufu zokukhansela kungaholela emiphumeleni emihle kakhulu kanye nokuphulukiswa okusheshayo, kodwa ukuqapha ngokucophelela nokuphathwa kwezinkinga kubalulekile ukuze kube nemiphumela emihle.
Imibuzo Evame Ukubuzwa
