Femoral Gamma Interlocking Nail II (Me Intertan)

Cov khoom siv ntawm PFNA femoral gamma interlocking intramedullary nail system yog titanium alloy, uas muaj PFNA femoral gamma interlocking intramedullary nail II (los ntawm hom txheem thiab hom ntev mus rau sab laug thiab sab xis), xauv cov ntsia hlau, hniav ntsia hlau, lag screws, tail caps Thiab xauv ntsia hlau tail cap composition. Lub kaum sab xis 5-degree valgus ntawm qhov kawg proximal ntawm lub hau tseem ceeb muab txoj hauv kev tsawg kawg nkaus rau lub apex ntawm lub trochanter loj dua. Qhov kev tsim trapezoidal seem ntawm qhov kawg proximal ntawm lub hau tseem ceeb txhim kho kev ruaj khov ntawm proximal femur thiab pab txhawb kev hnyav thaum ntxov. Cannulated stabilizing screws pre-muab tso rau hauv lub hau tail cap tuaj yeem nruj yog tias tsim nyog kom tshem tawm cov slippage postoperative ntau dhau. Qhov tshwj xeeb sib koom ua ke interlocking ntsia hlau tsim muab kev ruaj khov zoo thiab tiv thaiv kev tig, thiab qhov cuam tshuam tseem ceeb thaum lub sijhawm ntawm kev ntsia hlau hauv compression ntsia hlau. Lub qhov ntsia hlau kawg tuaj yeem xaiv qhov sib txuas dynamic lossis static, siv 5 hli sab hauv hexagon los tuav lub ntsia hlau sib txuas, thiab qhov tsim tshwj xeeb ntawm qhov kawg distal tuaj yeem txo qhov kev ntxhov siab thiab pab txhawb kev tawg nyob ib puag ncig lub prosthesis distal. Cov khoom tau txhim kho thiab ua kom zoo dua los ntawm PFNA, uas yog qhov tsim nyog dua rau cov neeg mob laus uas muaj osteoporosis. Raws li qhov kev laus thoob ntiaj teb tam sim no, nws yuav tau txais kev lag luam dav dua.
