Isikrufu sePolyaxial Pedicleziye zaguqula icandelo lotyando lomqolo, zenza ukuba oogqirha babe nokuguquguquka okukhulu nokuzinza ngexesha lokwenza utyando lokulungisa umqolo. Ezi zixhobo zintsha zenzelwe ukwamkela ii-engile ezahlukeneyo zokubeka izikrufu, zibonelela ngokuguquguquka okukhulu ekulungelelaniseni nasekulungiseni umqolo.
Inzuzo ephambili yeizikrufu zepedicle ze-titanium yomqoloikwindlela yayo eyahlukileyo yoyilo lwebhola kunye nesokethi. Oku kuvumela isikrufu ukuba sijikeleze ngaphakathi kwentonga, okuvumela ugqirha ukuba alungise i-engile yaso emva kokufakelwa. Oku kuguquguquka kubaluleke kakhulu xa kunyangwa ukukhubazeka komqolo okuntsonkothileyo, apho ukubeka ngokuchanekileyo kubalulekile ukuze unyango luphumelele. Ngenxa yezikrufu ze-polyaxial zivumela ukulungiswa emva kokubekwa, zinceda ukunciphisa umngcipheko weengxaki ezinxulumene nokungahambi kakuhle.
Ukongeza ekubeni nokuzivumelanisa nezimo kakuhle,isikrufu sepedicleikwabonelela ngozinzo oluphezulu kunezikrufu ze-monoaxial zemveli. Olu buchule bokutshixa isikrufu kwiindlela ezahlukeneyo buphucula ukuqina kolwakhiwo ngokubanzi, okubalulekileyo ekugcineni uzinzo lomqolo ngexesha lenkqubo yokuphiliswa. Oku kubaluleke kakhulu ngexesha lotyando lokuhlanganisa umqolo, apho injongo ikukukhuthaza ukukhula kwamathambo kunye nokufezekisa ukudibana okukhuselekileyo phakathi kwamathambo angasemva.
Ububanzi beinkqubo yesikrufu sepedicle yomqolokuxhomekeke kwisicelo esithile kunye neemfuno zomzimba zesigulana. Ngokwesiqhelo, eziisikrufu sepedicle yomqoloububanzi bayo buqala kwi-4.0 mm ukuya kwi-7.0 mm. Ukukhetha ububanzi kubalulekile, njengoko kuchaphazela amandla okutsalwa kwesikrufu, uzinzo, kunye neempawu zebhayoloji zizonke.Isikrufu sePedicle spinalezineedayamitha ezinkulu ngokubanzi zinika amandla kunye nozinzo olukhulu, nto leyo ezenza zifaneleke kwizigulana ezinethambo elinobunzima obuphezulu okanye ezo zifuna ukulungiswa okukhuselekileyo.
