Yintoni ipleyiti yokutshixa
Ipleyiti yokutshixa yipleyiti yokulungisa ithambo apho iintloko zescrew ezihambelanayo zitshixa kwimingxuma yepleyiti, yenze i-angular-stable plate-screw construct. Ngokungafaniyo nezikrufu eziqhelekileyo, izikrufu zokutshixa akufuneki zitsale ipleyiti ngokuqinileyo ethanjeni ukumisela olo qhagamshelwano. 'Iipleyiti ezitshixiweyo,' 'iipleyiti zethambo lokutshixa' kunye 'neenkqubo zokutshixa zescrew plate' ziqhele ukuchaza olu didi lofakelo. [1]
Kubathengisi bamathambo kunye namaqela okuthenga esibhedlele, umbuzo osebenzayo ayikokuba ipleyiti itshixiwe. Kukuba ingaba ipleyiti, izikrufu, izixhobo kunye noxwebhu zenza inkqubo ehambelanayo ye-anatomy ecetywayo kunye nemarike. Esi sikhokelo sichaza indlela, iikhonsepthi eziphambili zokulungisa kunye nolwazi olucelwayo ngaphambi koku-odola.
