Yini i-mini fragment?

Ucezu oluncane lubhekisela ohlotsheni lokufakelwa kwamathambo olusetshenziselwa ukulungisa amathambo amancane nezingcezu zamathambo, ngokuvamile lawo anobubanzi obungu-2.0 kuye 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:

1. Ingxenye yesithathu yamapuleti amashubhu: Lawa asetshenziselwa izingcezu zamathambo ezincane noma izingcezu zamathambo ezincane ezinendawo elinganiselwe yokulungiswa, njengasesandleni, esihlakaleni, naseqakaleni.

2. Ama-T-plates: Lawa mapuleti avame ukusetshenziswa ekuqhekekeni kwe-distal radius, iqakala, kanye ne-calcaneus.

3. L-amapuleti: Lawa mapuleti asetshenziswa ekuqhekekeni okudinga ukulungiswa okuqondile ku-axis ende yethambo, njengokuphuka kwe-distal femoral.

4. H-amapuleti: Lawa mapuleti asetshenziswa ekuqhekekeni kwe-tibia eseduze, kanye nokwelapha okungezona izinyunyana.

5. Ama-Y-plates: Lawa mapuleti asetshenziselwa ukuphuka kwe-proximal humerus, i-clavicle, ne-distal femur.

6. 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 zepuleti lokukhiya?

Amapuleti okukhiya ngokuvamile enziwa ngezinto ezihambisana ne-biocompatible njenge-titanium, i-titanium alloy, noma insimbi engagqwali. Lezi zinto zinamandla amahle kakhulu, ukuqina, nokumelana nokugqwala, okuzenza zilungele ukusetshenziswa ekufakweni kwamathambo. Ngaphezu kwalokho, ayi-inert futhi ayiphenduli ngezicubu zomzimba, inciphisa ingozi yokwenqatshwa noma ukuvuvukala. Amanye amapuleti okukhiya angase ahlanganiswe nezinto ezifana ne-hydroxyapatite noma ezinye izigqoko ukuze kuthuthukiswe ukuhlanganiswa kwazo nezicubu zethambo.

Iliphi ipuleti elingcono le-titanium noma insimbi engagqwali?

Womabili amapuleti e-titanium kanye nensimbi engagqwali avame ukusetshenziswa ekuhlinzeni amathambo, okuhlanganisa namapuleti okukhiya. 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, iyimpahla enamandla futhi eqinile futhi ehambisana ne-biocompatible futhi imelana nokugqwala. Isetshenziswe ekufakweni kwe-orthopedic amashumi eminyaka futhi iyinto ezanyiwe futhi eyiqiniso. 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:

1. 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.

2. Amandla nokuqina: I-Titanium ingenye yezinsimbi eziqine kakhulu nezihlala isikhathi eside, okuyenza ibe into efanelekile yezimila ezidinga ukumelana nezingcindezi nobunzima bokusetshenziswa kwansuku zonke.

3. 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.

4. 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.
