Pasentị iri anọ na isii nke ọkpụkpụ azụ ụkwụ na-agbagharị agbagharị na-esokwa ọkpụkpụ azụ azụ nke malleolar. Ụzọ posterolateral maka ịhụ anya ozugbo na idozi malleolus posterior bụ usoro ịwa ahụ a na-ejikarị eme ihe, na-enye uru biomechanical ka mma ma e jiri ya tụnyere mbelata mechiri emechi na idozi skru anteroposterior. Agbanyeghị, maka iberibe ọkpụkpụ azụ azụ buru ibu malleolar ma ọ bụ ọkpụkpụ azụ azụ nke gụnyere posterior colliculus nke medial malleolus, ụzọ posteromedial na-enye echiche ịwa ahụ ka mma.
Iji tụnyere oke ikpughe nke malleolus posterior, nrụgide dị na ngwugwu akwara, na anya dị n'etiti mbepụ ahụ na ngwugwu akwara n'ofe ụzọ atọ dị iche iche nke posteromedial, ndị nchọpụta mere nnyocha banyere cadaveric. E bipụtara nsonaazụ ya n'oge na-adịbeghị anya na akwụkwọ akụkọ FAS. A chịkọtara ihe ndị a chọpụtara dịka ndị a:
Ugbu a, e nwere ụzọ atọ dị mkpa isi mee ka a mata posteromedial malleolus nke dị n'azụ:
1. Ụzọ Mmalite nke Medial Posteromedial (mePM): Ụzọ a na-abanye n'etiti nsọtụ azụ nke medial malleolus na tendon azụ nke tibialis (Foto nke 1 na-egosi tendon azụ nke tibialis).
2. Ụzọ Posteromedial nke Agbanweworo (moPM): Ụzọ a na-abanye n'etiti akwara azụ nke tibialis na akwara ogologo nke flexor digitorum (Foto nke 1 na-egosi akwara azụ nke tibialis, Foto nke 2 na-egosi akwara ogologo nke flexor digitorum).
3. Ụzọ Posteromedial (PM): Ụzọ a na-abanye n'etiti nsọtụ etiti nke akwara Achilles na akwara flexor hallucis longus (Foto nke 3 na-egosi akwara Achilles, Foto nke 4 na-egosi akwara flexor hallucis longus).
Banyere nrụgide dị na ngwugwu akwara ozi, usoro PM nwere nrụgide dị ala na 6.18N ma e jiri ya tụnyere ụzọ mePM na moPM, nke na-egosi obere ohere nke mmerụ ahụ traction intraocular na ngwugwu akwara ozi.
N'ihe gbasara oke ikpughe nke malleolus azụ, ụzọ PM na-enyekwa ohere ka ukwuu ikpughe, na-enye ohere maka ịhụ ihe malleolus azụ 71%. Ma e jiri ya tụnyere ya, ụzọ mePM na moPM na-enye ohere maka ikpughe ihe malleolus azụ 48.5% na 57%, n'otu n'otu.
● Ihe osise a na-egosi oke ikpughe nke malleolus azụ maka ụzọ atọ ahụ. AB na-anọchite anya oke ikpughe nke malleolus azụ, CD na-anọchite anya oke ikpughe, CD/AB bụkwa oke ikpughe. Site n'elu ruo ala, a na-egosi oke ikpughe maka mePM, moPM, na PM. O doro anya na ụzọ PM nwere oke ikpughe kachasị.
Banyere anya dị n'etiti mbepụ ahụ na ngwugwu akwara ozi, ụzọ PM nwekwara anya kachasị elu, nke ruru 25.5mm. Nke a karịrị 17.25mm nke mePM na 7.5mm nke moPM. Nke a na-egosi na ụzọ PM nwere obere ohere nke mmerụ ahụ akwara ozi n'oge ịwa ahụ.
● Ihe osise a na-egosi anya dị n'etiti mbepụ ahụ na ngwugwu akwara ọbara maka ụzọ atọ ahụ. Site n'aka ekpe gaa n'aka nri, a na-egosi anya dị iche iche maka ụzọ mePM, moPM, na PM. O doro anya na ụzọ PM nwere anya kachasị site na ngwugwu akwara ọbara.
