Kedu ka esi zere ntinye 'in-out-in' nke skru femoral olu n'oge ịwa ahụ?

"N'ihi na ndị na-abụghị okenye femoral olu mgbawa, nke a na-ejikarị ime fixing usoro bụ 'triangle inverted' nhazi na atọ kposara. Abụọ kposara na-enịm nso na ihu na azụ cortices nke femoral olu, na otu ịghasa na-positioned n'okpuru. Nlegharị anya n'akụkụ, a na-ahụ ụkpụrụ '3-screw' ka a na-ahụta nhazi a ka ọ kachasị mma maka skru.

"Mgbatị semflex femoral artery medial bụ isi ọbara na-enye isi femoral. Mgbe etinyere skru 'in-out-in' n'elu akụkụ azụ nke olu femoral, ọ na-ebute ihe ize ndụ nke mmerụ ahụ nke iatrogenic vaskụla, nwere ike imebi ọbara na-enye n'olu femoral na, n'ihi ya, na-emetụta ọgwụgwọ ọkpụkpụ."

"Iji gbochie ihe omume nke 'in-out-in' (IOI), ebe skru na-agafe n'elu cortex dị n'olu femoral, na-apụ na ọkpụkpụ cortical, ma banyeghachi n'olu femoral na isi, ndị ọkà mmụta ma n'ime ụlọ na mba ụwa ejiriwo usoro nyocha ihe inyeaka dị iche iche.
