Msomali Wolumikizana wa Femoral Gamma II (Small Intertan)

Zipangizo za PFNA femoral gamma interlocking intramedullary nail system ndi titanium alloy, yomwe imakhala ndi PFNA femoral gamma interlocking intramedullary nail II (kuchokera ku mtundu wamba ndi mtundu wautali kupita kumanzere ndi kumanja), misomali yotseka, misomali ya blade, zomangira zotsalira, zipewa za mchira ndi kapangidwe ka chipewa cha mchira chotseka. Ngodya ya madigiri 5 ya valgus kumapeto kwa proximal ya screw yayikulu imapereka njira yocheperako yolowera pamwamba pa trochanter yayikulu. Kapangidwe ka gawo la trapezoidal kumapeto kwa proximal ya screw yayikulu kamathandizira kukhazikika kwa proximal femur ndikuthandiza kunyamula kulemera koyambirira. Zomangira zokhazikika zomwe zimayikidwa kale mu tail cap zitha kumangidwa ngati kuli kofunikira kuti zithetse kutsetsereka kwambiri pambuyo pa opaleshoni. Kapangidwe kapadera ka screw kotseka kolumikizana kamapereka kukhazikika kwabwino komanso kuthekera koletsa kuzungulira, komanso mphamvu yayikulu yokakamiza panthawi yokonza screw yokakamiza. Bowo la distal screw lingasankhe lolumikizana mwamphamvu kapena mosasunthika, pogwiritsa ntchito hexagon yamkati ya 5mm kuti igwire screw yolumikizana, ndipo kapangidwe kapadera ka hairpin bifurcation kumapeto kwa distal kangachepetse kupsinjika ndikuthandizira kusweka kwa fupa lozungulira distal prosthesis. Chogulitsachi chakonzedwa bwino ndi kukonzedwa ndi PFNA, chomwe chili choyenera kwambiri kwa odwala okalamba omwe ali ndi matenda a osteoporosis. Malinga ndi momwe zinthu zilili padziko lonse lapansi, chidzakhala ndi msika waukulu.
