Femoral Gamma Interlocking Nail II (Small Intertan)

Zomwe zili mu PFNA femoral gamma interlocking intramedullary misomali system ndi titaniyamu aloyi, yomwe imakhala ndi PFNA femoral gamma interlocking intramedullary nail II (kuchokera pamtundu wokhazikika ndi mtundu wautali kupita kumanzere ndi kumanja), misomali yotseka, misomali yamasamba, zomangira zamkati, zipewa za mchira Ndi loko. Mbali ya 5-degree valgus angle kumapeto kwa zomangira zazikulu imapereka njira yocheperako yofika pamwamba pa trochanter yayikulu. Kapangidwe ka gawo la trapezoidal kumapeto kwenikweni kwa screw yayikulu kumakulitsa kukhazikika kwa proximal femur ndikuthandizira kulemera koyambirira. Zomangira zokhazikika zokhazikika zomwe zidayikidwa kale mu kapu ya mchira zitha kumangika ngati kuli kofunikira kuti muchepetse kutsika kwambiri kwapambuyo pa opaleshoni. Kapangidwe kake kapadera kophatikizana ndi screw screw kumapereka kukhazikika kwabwino komanso kuthekera kolimbana ndi kuzungulira, komanso kupsinjika kwakukulu panthawi yopukutira mu screw screw. Bowo la distal screw limatha kusankha kulumikiza kosunthika kapena kokhazikika, kugwiritsa ntchito 5mm hexagon yamkati kuti igwiritsire wononga zolumikizirana, ndipo mawonekedwe apadera a hairpin bifurcation kumapeto kwa distal amatha kuchepetsa kupsinjika ndikuthandizira kuti ma fractures aphwanyike kuzungulira distal prosthesis. Chogulitsacho chimapangidwa bwino ndikukongoletsedwa ndi PFNA, yomwe ili yoyenera kwa odwala okalamba omwe ali ndi osteoporosis. Pansi pa ukalamba wapadziko lonse lapansi, ipeza msika wokulirapo.
