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

"Maka mgbaji n'olu femoral nke na-abụghị okenye, usoro nhazi ime ụlọ a na-ejikarị eme ihe bụ nhazi 'triangle inverted' nwere skru atọ.A na-edobe skru abụọ nso na ihu ihu na azụ nke olu femoral, na otu nkedo ka edobere n'okpuru.N'ihe nlele anteroposterior, skru abụọ dị nso na-adaba, na-eme ụkpụrụ '2-screw', ebe n'akụkụ ihu, a na-ahụ ụkpụrụ '3-screw'.A na-ewere nhazi a dị ka ebe kachasị mma maka skru.

"Iji gbochie ihe omume 'in-out-in' (IOI), ebe skru na-agafe n'elu cortex dị n'olu femoral, na-apụ n'ọkpụkpụ cortical, na-abanyekwa n'olu femoral na isi, ndị ọkà mmụta ma n'ime ụlọ na mba ụwa. ejirila usoro ntule inyeaka dị iche iche.Acetabulum, nke dị n'elu akụkụ elu nke olu femoral, bụ ịda mbà n'obi na-agbakọta na ọkpụkpụ.Site n'ịmụ mmekọrịta dị n'etiti kposara etinyere n'elu akụkụ azụ nke olu femoral na acetabulum na echiche anteroposterior, mmadụ nwere ike ịkọ ma ọ bụ chọpụta ihe ize ndụ nke ịghasa IOI."
