I.Ndezvipi zvinetso zvinosangana nembambo yefemur?
Sisitimu yezvipikiri inovhara humerus-multidimensional locking yakasiyana zvishoma nesisitimu yezvipikiri inovhara humerus intramedullary.
Sisitimu yehura yeHumerus interlocking intramedullary ine nzara inovhara humeral, banga rekutenderera humeral, chivharo chinokiya, nzara nechivharo uye chivharo chekupedzisira chakarebeswa. Kunyange zvazvo sisitimu yehura yehumerus interlocking-multidimensional locking ine sisitimu yehura yekubatanidza humeral-multidimensional locking (mhando dzekuruboshwe nerudyi),Φ4.5 sikuruu yekukiya ine mativi akawanda,Φ3.5 sikuruu yekukiya, chivharo chekumagumo uye chivharo chekumagumo chakarebeswa.
Chii chinokonzera musiyano uyu pakatimasisitimu ezvipikiri akabatana nehumerus-multidimensional lockuyehumerus interlocking intramedullary nail system?
Dhizaini yekukiya ine mativi akawanda inogona kukiya nzvimbo yekutyoka munzira dzakasiyana-siyana, ichipa simba rakasimba uye rakavimbika rekugadzirisa, ichideredza kufamba kwemucheto wekutyoka, uye ichibatsira kupora kwekutyoka. Yakakodzera mamiriro akaomarara ekutyoka. Sisitimu yemazino isina mativi akawanda inokiya yemukati memudullary yefemur inonyanya kukodzera mamiriro ari nyore ekutyoka.
II.Ndezvipi zvakanakira kurovera jira mukati memedullary?
Humerus interlocking nail system-multidimensional locking izwi rezvekurapa repamusoro-soro rinoreva kutyoka kwehumeral. Zvakanakira zvaro zvinoratidzwa muzvinhu zvinotevera:
1)Shinda yakakosha yemukati ye screws yekuvandudza kugadzikana.
2)Sikuruu mbiri dze cortical dzinowedzera kugadzikana kwekutyoka kwakachinjika uye kupfupika.
3)Zvigadzirwa zvembambo pfupi nembambo refu uye kune mhando dzakawanda dzesikuruu dzinosarudza kugadzirisa kupwanyika kuri nyore uye kwakaoma kweproximal humerus nehumeral axis. Zvichienderana nebone shaft, dhizaini inodzoreka, kufamba kudiki, zvinosimudzira kubatana.
4)Nekushandisa nzira dzisinganyanyi kukuvadza, kucheka kwacho kudiki, zvichideredza kukuvara kwenyama dzakapfava dzakapoteredza uye zvichideredza njodzi yehutachiona nematambudziko mushure mekuvhiyiwa.
5)Ine kugadzikana kwakanaka kweaxial uye kutenderera, inogona kutsungirira mutoro mukuru wemuviri, uye inobatsira varwere kutanga kushanda.
III.Ndinofanira kutanga rini kurapwa mushure mekutyoka kwehumerus?
Kurapa kwekuvhiyiwa：
1) Kurovera makumbo mudumbu: Uku ndiko kurapwa kunonyanya kufarirwa kune mapfupa emudumbu, kunyanya kune varwere vadiki uye vanoshanda nesimba.
2)Kugadzika kweplate: Kune vamwe varwere vakatyoka zvakaoma kana varwere vasingakodzeri kuroverwa intramedullary nails, kugadzika kweplate kunogona kusarudzwa.
3)Chinogadzirisa mapfupa kunze: Chinonyanya kushandiswa pakukuvara kwakavhurika, varwere vane kukuvara kwakawanda kana avo vanoda kugadziriswa kwenguva pfupi.
4）Kupatsanurwa Kwechiuno: Pakupwanyika kwechiuno chepedyo, kunyanya kupwanyika kwemutsipa wechiuno chepamberi kana kupwanyika kwechikamu chemusoro muvarwere vakwegura, kupatsanurwa kwechiuno chepamberi kunogona kudiwa.
Kurapa kusiri kwekuvhiya:
1）Kurapa nekushandisa simba remusana: Kwakakodzera vamwe varwere vasina kukodzera kuvhiyiwa, vakaita sevanhu vakwegura, avo vane hutano husina kunaka, kana avo vane zvirwere zvakakomba zvemukati.
2）Kugadzika kwepurasita kana simbi: Kune mamwe mavanga echikadzi ari nyore uye asina kuchinjika, kugadzika kwepurasita kana simbi kunogona kushandiswa.
