Isikulufu se-Polyaxial Pedicleziye zashintsha kakhulu insimu yokuhlinzwa komgogodla, zenza odokotela abahlinzayo bakwazi ukuguquguquka okukhulu nokuzinza ngesikhathi benza ukuhlinzwa kokuqinisa umgogodla. Lawa madivayisi amasha aklanyelwe ukwamukela ama-engeli ahlukahlukene okubeka izikulufo, anikeze ukuguquguquka okukhulu ekuqondeni nasekulungiseni umgogodla.
Inzuzo eyinhloko yeizikulufu ze-pedicle ze-titanium spinekulele ekwakhiweni kwazo okuyingqayizivele kwebhola nesokhethi. Lokhu kuvumela isikulufu ukuthi sijikeleze ngaphakathi kwenduku, okuvumela udokotela ohlinzayo ukuthi alungise i-engeli yaso ngemva kokufakelwa. Lokhu kuguquguquka kubaluleke kakhulu lapho welapha ukukhubazeka komgogodla okuyinkimbinkimbi, lapho ukubeka khona indawo eqondile kubalulekile ekwelashweni okuphumelelayo. Ngenxa yezikulufu ze-polyaxial zivumela ukulungiswa ngemva kokufakwa, zisiza ekunciphiseni ingozi yezinkinga ezihlobene nokungalungi kahle.
Ngaphezu kokuba nokuzivumelanisa nezimo okuhle,isikulufu se-pediclefuthi inikeza ukuzinza okuphezulu kunezikulufo zendabuko ze-monoaxial. Leli khono lokukhiya isikulufo ngezindlela eziningi lithuthukisa ukuqina kokwakheka okuphelele, okubalulekile ekugcineni ukuzinza komgogodla ngesikhathi senqubo yokuphulukiswa. Lokhu kubaluleke kakhulu ngesikhathi sokuhlinzwa kokuhlanganiswa komgogodla, lapho umgomo uwukukhuthaza ukukhula kwamathambo nokufeza ukuhlangana okuphephile phakathi kwamathambo angemuva.
Ububanzi be-uhlelo lwesikulufu se-pedicle yomgogodlakuncike ekusetshenzisweni okuthile kanye nezidingo zomzimba wesiguli. Ngokuvamile, lokhuisikulufu se-pedicle yomgogodlaububanzi busukela ku-4.0 mm kuya ku-7.0 mm. Ukukhetha ububanzi kubalulekile, njengoba kuthinta amandla okudonsa kwesikulufu, ukuzinza, kanye nezakhiwo ze-biomechanical zizonke.Isikulufu se-pedicle spinalezinobubanzi obukhulu ngokuvamile zinikeza amandla amakhulu nokuzinza, okwenza zifaneleke ezigulini ezinamathambo amaningi noma lezo ezidinga ukulungiswa okuphephile.
