Nā kikoʻī o nā huahana
Hana ʻia ia me nā mea TC4.
ʻO ke ʻano o nā wili he HA iwi iwi iwi, HB cancellous iwi wili a me HC locking screw.Loaʻa nā wili HB i ka milo piha a me ka hapalua.
Loaʻa i nā ʻuliki o nā ʻano nui nā mea hana ʻoki like ʻole.
Nui o HA: Φ2.0, Φ2.5,Φ2.7, Φ3.5, Φ4,5
Nui o HB;Φ4.0 piha, Φ4.0 hapalua, Φ6.5 piha, Φ6.5 hapalua

Hoʻohana ʻia nā wili cortical maʻamau no nā iwi diaphyseal, me ke poʻo like (3.5 + 4.5) a me nā kaula asymmetrical.
Hoʻohana ʻia nā wili iwi cancellous maʻamau no ka metaphysis a i ʻole epiphysis, me ke anawaena nui o waho a me ke kaula hohonu.
He ʻelua ʻāpana mīkini ʻenehana Lag screw: 1 ke kaha pōʻai (friction force) ma ke kaula, 2 ka ikaika axial i ka wā e hoʻopaʻa ʻia ai, ʻo ka wīwī a i ʻole ka lua hoʻoheheʻe e hiki ai ke huki ʻia ka poloka nahā contralateral i ke poʻo wili.
Ka hoʻokaʻawale ʻana o nā wili
ʻO ka wili cortical maʻamau, no ka iwi diaphyseal, ke poʻo like ʻole, ke kaula asymmetrical.
ʻO ka wili iwi cancellous maʻamau, hoʻohana ʻia no ka metaphysis a i ʻole epiphysis, ke anawaena nui o waho, ke kaula hohonu.
Nā wili kūikawā ʻē aʻe
1. ʻO ka wili maloʻo, ka wili liʻiliʻi ma waena o ka iwi a me ka pā
2.ʻO ka laka paʻa, ke poʻo a me ka paʻa ʻana o ka pā (kiʻi paʻa)
3. ʻO Schanz screw, hoʻohana ʻia no ka bracket fixation waho
