Indlela yokuSikrola engatshixwayo
Iimveliso Iinkcukacha
Yenziwe ngezinto ze-TC4.
Iindidi zezikrufu zi-HA cortical bone screw, i-HB cancellous bone screw kunye ne-HC yokutshixa isikrufu.Izikrufu ze-HB zifumaneka kumsonto opheleleyo kunye nesiqingatha somsonto.
Izikrufu zobukhulu obahlukeneyo zinezixhobo zotyando ezihambelanayo.
Ubungakanani be-HA: Φ2.0, Φ2.5,Φ2.7, Φ3.5, Φ4,5
Ubungakanani be-HB;Φ4.0igcwele, Φ4.0isiqingatha, Φ6.5 izele, Φ6.5 isiqingatha
Iingcebiso zonyango
Izikhonkwane eziqhelekileyo ze-cortical zisetyenziselwa amathambo e-diaphyseal, kunye nentloko ye-symmetrical (3.5 + 4.5) kunye nemicu ye-asymmetrical.
Izikrufu zamathambo eziqhelekileyo zisetyenziselwa i-metaphysis okanye i-epiphysis, enobubanzi obukhulu bangaphandle kunye nentambo enzulu.
Itekhnoloji ye-screw ye-Lag inamacandelo amabini omatshini: i-1 amandla ajikelezayo (i-friction force) ecaleni komsonto, 2 amandla e-axial xa uqiniswa, i-screw screw okanye umngxuma wokutyibilika uvumela ibhloko ye-fracture ye-contralateral ukuba itsalwe ngakwintloko ye-screw.
Ukuhlelwa kwezikrufu
Isikrufu se-cortical standard, kwithambo le-diaphyseal, intloko elinganayo, intambo ye-asymmetrical.
Isikrufu samathambo esisemgangathweni, esisetyenziselwa i-metaphysis okanye i-epiphysis, i-diameter yangaphandle enkulu, intambo enzulu.
Ezinye izikrufu ezikhethekileyo
1. Screw esomileyo, ukukhuhlana okuncinci phakathi kwethambo kunye nepleyiti
2.Isikrufu sokutshixa, intloko kunye nokutshixa ipleyiti (i-angle esisigxina)
3. Schanz screw, esetyenziselwa isibiyeli sokulungiswa kwangaphandle
