Yini i-mini fragment?
Ucezu oluncane lubhekisela ohlotsheni Isifakelo samathambo olusetshenziselwa ukulungisa amathambo amancane nezingcezu zamathambo, ngokuvamile lezo ezinobubanzi obungu-2.0 ukuya ku-3.5 mm. Lezi zimila zivame ukusetshenziswa ekuhlinzweni kwezandla nezinyawo, kanye nokunye ukuhlinzwa okubandakanya izingcezu ezincane zamathambo. Ama-Mini fragment implants aklanyelwe ukuhlinzeka ngokulungiswa okuzinzile futhi akhuthaze ukuphulukiswa, futhi atholakala ngezindlela ezihlukahlukene nosayizi ukuze kuhlangatshezwane nezidingo ezihlukene zokuhlinzwa. Ngokuvamile zenziwe ngezinto ezihambisana ne-biocompatible njenge-titanium noma insimbi engagqwali, futhi ngokuvamile zifakwa kusetshenziswa izinsimbi ezikhethekile.
Yiziphi izinhlobo ze-mini fragment?
Amapuleti ama-mini fragment atholakala ngezinhlobo nosayizi abahlukahlukene ukuze alingane nezindawo ezihlukahlukene ze-anatomical nosayizi bamathambo. Ezinye izinhlobo ezijwayelekile zamapuleti ama-mini fragment zifaka:
Ingxenye yesithathu yamapuleti amashubhu: Lawa asetshenziselwa izingcezu zamathambo ezincane noma izingcezu zamathambo ezincane ezinendawo elinganiselwe yokulungiswa, njengasesandleni, esihlakaleni, naseqakaleni.
Ama-T-plates: Lawa mapuleti avame ukusetshenziswa ekuqhekekeni kwe-distal radius, iqakala, kanye ne-calcaneus.
Amapuleti e-L: Lawa mapuleti asetshenziswa ekuqhekekeni okudinga ukulungiswa kwe-perpendicular ku-axis ende yethambo, njengokuphuka kwe-distal femoral.
H-amapuleti: Lawa mapuleti asetshenziswa ekuqhekekeni kwe-tibia eseduze, kanye nokwelapha okungezona izinyunyana.
Ama-Y-plates: Lawa mapuleti asetshenziselwa ukuphuka kwe-proximal humerus, i-clavicle, ne-distal femur.
Amapuleti e-hook: Lawa mapuleti asetshenziswa ekuqhekekeni okuyinkimbinkimbi lapho izindlela ezijwayelekile zokucwenga zingenzeki noma zehlulekile, njengasekuqhekekeni kwethafa le-lateral tibial plateau.
Kubalulekile ukuqaphela ukuthi izinhlobo nosayizi bamapuleti ama-mini fragment asetshenzisiwe azoncika kuphethini ethile yokuphuka kanye nokuthandwa ngudokotela ohlinzayo.
Izinto ze I-locking plate ?
Ama-locking plate ngokuvamile zenziwe ngezinto ezihambelana ne-biocompatible njenge-titanium, i-titanium alloy, noma insimbi engagqwali. Lezi zinto zinamandla amahle kakhulu, ukuqina, nokumelana nokugqwala, okuzenza zilungele ukusetshenziswa ku Izifakelo zamathambo . Ngaphezu kwalokho, ayi-inert futhi ayiphenduli ngezicubu zomzimba, ukunciphisa ingozi yokwenqatshwa noma ukuvuvukala. Okunye Ama-locking plate kungase futhi kuhlanganiswe nezinto ezifana ne-hydroxyapatite noma ezinye izimbobo ukuze kuthuthukiswe ukuhlanganiswa kwazo nezicubu zethambo.
Iliphi ipuleti elingcono le-titanium noma insimbi engagqwali?
Kokubili amapuleti e-titanium nensimbi engagqwali avame ukusetshenziswa ekuhlinzeni amathambo, okuhlanganisa ne Ama-locking plate . Ukukhetha phakathi kwalezi zinto ezimbili kuncike ezicini eziningana, okuhlanganisa uhlobo lokuhlinzwa, umlando wezokwelapha wesiguli kanye nezintandokazi, kanye nolwazi lukadokotela ohlinzayo kanye nalokho akuthandayo.
I-Titanium iyimpahla engasindi futhi eqinile ehambisana ne-biocompatible futhi imelana nokugqwala, okuyenza ibe ukukhetha okuhle kakhulu kokufakelwa kwezokwelapha. Amapuleti e-Titanium awaqinile kakhulu kunamapuleti ensimbi engagqwali, angasiza ekunciphiseni ukucindezeleka ethanjeni futhi akhuthaze ukuphulukiswa. Ukwengeza, amapuleti e-titanium anokukhanya okukhulu, okusho ukuthi awaphazamisi ukuhlolwa kwezithombe njenge-X ray noma i-MRI.
Insimbi engagqwali, ngakolunye uhlangothi, iyinto enamandla futhi eqinile futhi ehambisana ne-biocompatible futhi imelana nokugqwala. Isetshenziswe ku Izifakelo zamathambo amashumi eminyaka futhi iwumsebenzi ozanyiwe futhi oyiqiniso. Amapuleti ensimbi angabizi kakhulu kunamapuleti e-titanium, okungaba ukucatshangelwa kwezinye iziguli.
Kungani amapuleti e-titanium esetshenziswa ekuhlinzeni?
Amapuleti e-Titanium avame ukusetshenziswa ekuhlinzeni ngenxa yezakhiwo zawo eziyingqayizivele eziwenza abe yimpahla efanelekile yokufakelwa kwezokwelapha. Ezinye zezinzuzo zokusebenzisa amapuleti e-titanium ekuhlinzeni zifaka:
I-Biocompatibility: I-Titanium ihambisana kakhulu ne-biocompatible, okusho ukuthi akunakwenzeka ukuthi ibangele ukungezwani komzimba noma yenqatshwe amasosha omzimba. Lokhu kuyenza ibe impahla ephephile futhi enokwethenjelwa ukuze isetshenziswe ekufakweni kwezokwelapha.
Amandla nokuqina: I-Titanium ingenye yezinsimbi eziqine kakhulu nezihlala isikhathi eside, okuyenza ibe into efanelekile yezimila ezidinga ukumelana nezingcindezi nobunzima bokusetshenziswa kwansuku zonke.
Ukumelana nokugqwala: I-Titanium imelana kakhulu nokugqwala futhi mancane amathuba okuthi ibhekane noketshezi lomzimba noma ezinye izinto ezisemzimbeni. Lokhu kusiza ukuvimbela ukufakelwa ukuthi kungagqwali noma konakale ngokuhamba kwesikhathi.
I-Radiopacity: I-Titanium ine-radiopaque ephezulu, okusho ukuthi ingabonakala kalula kuma-X ray nokunye ukuhlola kwezithombe. Lokhu kwenza kube lula ukuthi odokotela baqaphe ukufakelwa futhi baqinisekise ukuthi kusebenza kahle.
