I.Ngayiphi injongo isikulufu se-cannulated sinembobo?
Asebenza kanjani amasistimu ngezikulufu ze-cannulated? Kusetshenziswa izintambo ezincane ze-Kirschner (izintambo ze-K) ezibhojwe ethanjeni ukuze kuqondiswe ama-trajectories ngezikulufu ngokunembile zibe izingcezu zamathambo amancane.
Ukusetshenziswa kwezintambo ze-K kugwema ukubhoboza ngokweqile izimbobo zokuhlola futhi kuvumela ukulungiswa kwezingcezu zamathambo eziseduze ngesikhathi sokufakwa isikulufu. Amathuluzi angenalutho nezikulufu ezingenalutho zifakwa ethanjeni phezu kwezintambo ze-K. Ukulungiswa kwesikulufu se-cannulated kuyasiza kumgogodla womlomo wesibeletho ukuze kuzinzise ukuphuka kwe-odontoid kanye nokwelapha ukungazinzi kwe-atlantoaxial.
Izikulufu ze-cannulated zinezinzuzo ezimbalwa uma ziqhathaniswa nezikulufi ezingashicileli: 1) izintambo ze-K ziqondisa indawo yesikulufu ethanjeni;
2)i-K-wire trajectory yenza ukuma kabusha kube lula uma i-trajectory yasekuqaleni yayingalungile;
3)izintambo ze-K zivumela ukulungiswa okuqhubekayo kwezingcezu zamathambo ezingaqinile;
4) Izintambo ze-K zivimbela ukunyakaza kwezingcezu zamathambo ezingazinzile ngesikhathi sokufakwa isikulufu.
Izinkinga ezihlobene ne-K-wire (ukuphuka, ukubekwa kabusha, nokuthuthuka) zingancishiswa kusetshenziswa amasu okusebenza anembile. Uhlelo olukhethekile lwethuluzi lesikulufu se-cannulated lathuthukiswa ngokukhethekile ukuze kulungiswe umlomo wesibeletho phezulu ukuze kuvunyelwe ukubhola nge-percutaneous kusetshenziswa imishini emide yokudonsa, amashethi ezicubu, iziqondiso zokubhoboza, nezintambo ezinde ze-K. Lawa mathuluzi avumela ukulethwa kwezikulufu ze-cannulated nge-engeli ephansi ukuya emgogodleni ngokusebenzisa ama-trajectories amade ezicubu ezithambile. Izikulufu ezingakheniwe zinezinzuzo ezibalulekile uma ziqhathaniswa nezikulufu ezingafakwanga ukuze kulungiswe umgogodla womlomo wesibeletho ongazinzile ohlelweni.
II.Iziphi izikulufo ezifakwe emathinini ezingcono noma izinzipho ze-intrameduallary?
Zombili izipikili ze-intramedullary nezinzipho ezifakwe emathini zingamathuluzi ezokwelapha asetshenziselwa ukulungiswa kwangaphakathi kwama-fractures. Ngamunye unezinzuzo zawo futhi afanele izinhlobo ezahlukene zokuphuka kanye nezidingo zokwelashwa.
| Uhlobo | Inzuzo |
| I-Intramedullary Nail | Umthelela wokulungisa izinzipho we-intramedullary ekuqhekekeni okuzinzile kwamathambo amade muhle, unokulimala okuncane nokopha okuncane. Ukulungiswa kwezinzipho kwe-Intramedullary kungokokulungiswa okumaphakathi. Uma kuqhathaniswa namapuleti ensimbi, izinzipho ze-intramedullary nazo zingavikela ubuqotho be-membrane ye-extraosseous, zivimbele ukulibaziseka ukuphuka kokuphuka, futhi zibambe iqhaza ekugwemeni ukutheleleka. |
| I-Cannulated Screw | Isetshenziswa ikakhulukazi ezindaweni ezifana nokuphuka kwentamo ye-femoral, enemiphumela ekhethekile yokulungiswa nokucindezela. Ngaphezu kwalokho, umonakalo mncane kakhulu futhi awadingi amapuleti ensimbi. |
III.Kunini lapho usebenzisa izikulufo zokukhansela vs cortical?
Izikulufu zeCancellous nezikulufu zecortical zombili izinhlobo zokufakelwa kwamathambo ezisetshenziswa ekulungiseni amathambo, kodwa zakhelwe izinhlobo ezahlukene zamathambo futhi zinezinhlelo zokusebenza ezihlukile:
I-Cancellous Screws iklanyelwe ngokukhethekile ukusetshenziswa ku-spongy, kancane kancane, kanye nezicubu zethambo le-trabecular, ezivame ukutholakala ekugcineni kwamathambo amade, njenge-femur kanye ne-tibia.Ngokujwayelekile isetshenziswa ezindaweni lapho ithambo linama-porous futhi lincane kakhulu, njengezifunda ze-metaphyseal zamathambo amade. Zivame ukusetshenziswa ezinqubweni ezibandakanya umgogodla, i-pelvis, nezingxenye ezithile zehlombe ne-hip.
I-Cortical Screws yakhelwe ukusetshenziswa ku-denser, ithambo le-cortical, elakha ungqimba lwangaphandle lwamathambo amaningi futhi liqinile kakhulu futhi linamandla kunethambo elikhansela. Ngokuvamile kusetshenziswe ezimweni lapho amandla amakhulu nokuzinza kuyadingeka, njengokulungiswa kwama-fractures ku-diaphysis (shaft) yamathambo amade. Zibuye zisetshenziswe kumadivayisi athile okulungisa angaphakathi namapuleti.
Kafushane, ukukhetha phakathi kwezikulufu zokukhansela nezikhohlo kuncike ohlotsheni lwethambo elilungiswayo kanye nezidingo ezithile zenqubo ye-orthopedic. Izikulufu ze-Cancellous zifanele ithambo elithambile, elinezimbotshana eziningi, kuyilapho izikulufi zecortical zilungele ithambo elicinene, elithwala umthwalo.
