Tīwiri Pedicle Polyaxialkua hurihia te ao o te pokanga tuaiwi, kia nui ake ai te ngāwari me te pumau o ngā taote pokanga i a rātou e mahi ana i ngā pokanga whakatika tuaiwi. Kua hangaia ēnei taputapu auaha hei whakauru i ngā momo koki whakatakotoranga tīwiri, kia nui ake ai te ngāwari o te whakatikatika me te whakatikatika i te tuaiwi.
Ko te painga matua ongā tīwiri waewae titanium tuaraKei roto i tōna hoahoa pōro-me-te-kōhao ahurei. Mā tēnei ka taea e te tīwiri te huri i roto i te tokotoko, ka taea e te taote pokanga te whakatika i tōna koki i muri i te whakaurunga. He mea nui tēnei ngāwari ina rongoatia ana ngā hapa uaua o te tuaiwi, he mea nui te tūnga tika mō te angitu o te maimoatanga. Nā te mea ka taea e ngā tīwiri polyaxial te whakatika i muri i te whakaurunga, ka āwhina i te whakaiti i te mōrearea o ngā raruraru e pā ana ki te he o te tūnga.
Haunga te pai o te urutau,tīwiri waewaehe nui ake hoki te pumau i ngā tīwiri monoaxial tuku iho. Mā tēnei kaha ki te raka i te tīwiri i ngā taha maha ka whakanui ake i te pakari o te hanganga whānui, he mea nui tēnei hei pupuri i te pumau o te tuaiwi i te wā whakaora. He mea nui rawa tēnei i te wā o te pokanga whakakotahitanga tuaiwi, ko te whāinga he whakatairanga i te tipu o te wheua me te whakatutuki i te hononga haumaru i waenga i ngā tuaiwi.
Ko te whānui o tepūnaha tīwiri waewae tuaiwika whakawhirinaki ki te tono motuhake me ngā whakaritenga tinana o te tūroro. I te nuinga o te wā, ko ēneitīwiri waewae tuaiwikei waenga i te 4.0 mm ki te 7.0 mm te whānui. He mea nui te whiriwhiri i te whānui, nā te mea ka pā ki te kaha kume o te tīwiri, te pumau, me ngā āhuatanga koiora whānui.Tīwiri waewae tuarahe nui ake te kaha me te pumau o ngā wheua, ā, he pai mō ngā tūroro he nui ake te kiato o te wheua, mō te hunga rānei e hiahia ana kia mau te whakapiri.
