He whara haumanu noa te whati o te kakau tibial. He painga koiora-ā-tinana te whakau whao ā-roto intramedullary, arā, he iti noa te whakaekenga me te whakau axial, ā, he otinga paerewa mō te maimoatanga pokanga. E rua ngā tikanga matua mō te whakau whao intramedullary tibial: te whakau suprapatellar me te whakau infrapatellar, me te huarahi parapatellar e whakamahia ana e ētahi tohunga.
Mō ngā whati o te 1/3 tata o te tibia, nā te mea me piko te turi i te huarahi infrapatellar, he ngāwari te piko whakamua o te whati i te wā o te pokanga. Nō reira, ko te huarahi suprapatellar te tikanga e taunakihia ana mō te maimoatanga.

Heoi, ki te mea he ārai ki te huarahi suprapatellar, pērā i te mate pukupuku o te kiko ngohengohe o te rohe, me whakamahi te huarahi infrapatellar. Ko te ārai i te piko o te pito whati i te wā pokanga he raruraru me aro atu. Ka whakamahia e ētahi tohunga ngā pereti maitai tapahi iti hei whakatika i te cortex o mua mō te wā poto, te whakamahi rānei i ngā whao ārai hei whakatika i te piko.

Hei whakaoti i tēnei raruraru, i whakamahia e ngā tohunga o tāwāhi tētahi tikanga iti rawa te whakaekenga. Nō nā tata nei te tuhinga i whakaputaina i roto i te maheni "Ann R Coll Surg Engl":
Kōwhiria kia rua ngā tīwiri hiako 3.5mm te matotoru, e tata ana ki te pito o te pito whati, whakauruhia tētahi tīwiri ki mua, ki muri hoki ki roto i ngā kongakonga wheua i ngā pito e rua o te whati, ā, waiho kia neke atu i te 2cm te tawhiti i waho o te kiri:
Puritia ngā kuku whakaiti kia mau tonu te whakaiti, kātahi ka whakaurua te whao intramedullary kia rite ki ngā tikanga tuku iho. Kia whakauruhia te whao intramedullary, tangohia te tīwiri.
He pai tēnei tikanga hangarau mō ngā take motuhake kāore e taea te whakamahi i ngā huarahi suprapatellar, parapatellar rānei, ā, kāore i te tūtohutia i ngā wā katoa. Tērā pea ka pā te whakatakotoranga o tēnei tīwiri ki te whakatakotoranga o te whao matua, tērā pea ka pakaru te tīwiri. Ka taea te whakamahi hei tohutoro i ngā āhuatanga motuhake.
