Chii chinonzi tekinoroji yeChipikiri chePfna?
PFNA (Proximal Femoral Nail Antirotation)Chipikiri cheFemur inzira yekuisa mukati isinganyanyi kupindira yakagadzirwa zvakanangana nekutyoka kwenhengo dzechikadzi dziri pedyo.
Ndezvipi zvakanakira zveChipikiri cheIntramedullary cheFemur?
Kugadzikana kweBiomechanical
Chipikiri cheIntramedullary inoshandisa dhizaini imwe chete yebanga remupendero. Nekubatanidza pfupa rinodzima, banga iri rinopa kugadzikana kunodzivirira kutenderera uye kwekona, zvichiita kuti rive rakakodzera zvakanyanya kune mapfupa akatyoka muvarwere vakwegura. Zvidzidzo zvekiriniki zvakaratidza kuti banga remupendero rinochengetedza mapfupa uye rinosimudzira huwandu hwemaminerari emapfupa, nokudaro richideredza njodzi yekukundikana kwekuisa mapfupa mushure mekuvhiyiwa.
Hunhu Hwokuvhiya Husingakuvadzi Zvishoma
Kuchekwa kudiki: Kuchekwa kwemativi kwenguva refu kweinenge 5 cm chete ndiko kunodiwa; nzvimbo yakatyoka haionekwe, izvo zvinoderedza kukuvara kwenyama yakapfava.
Nguva pfupi yekuvhiya: Maitiro acho anogona kupedzwa mukati memaminitsi makumi matatu kusvika makumi matanhatu paavhareji, anopfuura 30% mapfupi pane masisitimu ekare ekugadzirisa plate-screw.
Kurasikirwa neropa shoma: Kurasikirwa neropa panguva yekuvhiyiwa kunodzorwa pa50–100 mL, zvishoma pane kubudiswa kweropa pachena.
Rutsigiro rweKukurumidza Kugadziriswa
Varwere vanogona kumuka pamubhedha kuti vaende kunorara kwemazuva matatu kusvika mashanu mushure mekuvhiyiwa. Zvichibva paruzivo rwekiriniki rwevanhu vanodarika mazana maviri, mwero wekurarama kwemakore mashanu unodarika 80%, zvichiita kuti nzira iyi ive yakakodzera varwere vakwegura vane zvirwere zvakasiyana-siyana.
