PFNA Imisumari yimbere: Ubuyobozi bwuzuye
Mu rwego rwa ortopedie, kuvura kuvunika ikibuno bikomeje kuba umurimo utoroshye. Mugihe uburyo butandukanye bwo kubaga bwatejwe imbere mugihe, imisumari yimbere yagaragaye nkuguhitamo gukunzwe. Antirotation ya Proximal Femoral Nail Antirotation (PFNA) ni ubwoko bwimisumari yimbere yitabiriwe cyane kubera akamaro kayo mukuvura kuvunika ikibuno. Muri iki kiganiro, tuzatanga umurongo ngenderwaho ku musumari wa PFNA, ukubiyemo ibintu byose uhereye ku gishushanyo cyacyo kugeza ku buryo bwo kubaga, ubuvuzi bwa nyuma, ndetse n’ibibazo bishobora kuvuka.
1. Intangiriro
Kuvunika ikibuno nimpamvu isanzwe itera indwara nimpfu mubantu bageze mu zabukuru. Hamwe n’abaturage bageze mu za bukuru, umubare w’imvune zo mu kibuno ziteganijwe kwiyongera uko igihe kigenda. Kuvura kuvunika ikibuno ni ngombwa, kuko bishobora kugira ingaruka zikomeye kumibereho yumurwayi. Imisumari yimbere yabaye tekinike izwi cyane yo kubaga kuvura kuvunika ikibuno kubera akamaro n'umutekano. Mu bwoko butandukanye bwimisumari yimbere, imisumari ya PFNA yitabiriwe cyane.
2. Umusumari wa PFNA ni iki?
Umusumari wa PFNA ni ubwoko bwimisumari yimbere igenewe gutuza no gukosora kuvunika ikibuno. Nigikoresho cyegeranye cyane, anterograde, na cephalomedullary igikoresho cyinjijwe mumigezi ya femorale yegeranye. Umusumari wa PFNA utanga ituze kurubuga rwacitse mukwemerera kugabana imitwaro hagati yumusumari n'amagufwa. Igabanya kandi ibyago byo kunanirwa kwatewe no kugabanuka mugutanga anti-rotation stabilite.
3. Igishushanyo cya PFNA n'ibiranga
Imisumari ya PFNA igizwe na titanium cyangwa titanium alloy, ikaba biocompatible kandi itanga imbaraga nziza nigihe kirekire. Umusumari ufite icyuma gihanamye ku mpera yegeranye, igenewe guhuza umutwe wumugore no gutanga ituze ryizunguruka. Urubaho rufite kandi uburyo bwo kurwanya kuzunguruka, birinda kuzunguruka imisumari muri femur. Impera ya kure yimisumari ifite uburyo bwo gufunga, butuma habaho gukosorwa kure no guhagarara neza.
4. Ibyerekana kubaga PFNA
Imisumari ya PFNA ikoreshwa cyane cyane mukuvura imvune zidahindagurika hamwe na subtrochanteric kuvunika ikibuno. Irakoreshwa kandi mukuvura kuvunika ijosi ryumugore. Icyemezo cyo gukoresha PFNA kubaga imisumari biterwa nibintu bitandukanye nkimyaka yumurwayi, ubwiza bwamagufwa, ubwoko bwavunitse, hamwe nibyifuzo byo kubaga.
5. Ubuhanga bwo kubaga bwa PFNA Gutera imisumari
Ubuhanga bwo kubaga PFNA imisumari yimisumari ikubiyemo intambwe nyinshi. Uburyo busanzwe bukorwa munsi ya anesthesia rusange cyangwa umugongo. Umurwayi ashyizwe kumeza yamenetse, kandi fluoroscope ikoreshwa mukuyobora kwinjiza imisumari.Ubuhanga bwo kubaga bwa PFNA bwo gutera imisumari burimo intambwe nyinshi. Uburyo busanzwe bukorwa munsi ya anesthesia rusange cyangwa umugongo. Umurwayi ashyizwe kumeza yamenetse, kandi fluoroscope ikoreshwa mu kuyobora imisumari. Uburyo bwo kubaga burimo agace gato gakozwe hejuru ya trochanter nini, itanga uburyo bwo kugera ku gitsina cyegeranye. Umugozi uyobora noneho winjizwa unyuze hanyuma ukanyuzwa kumuyoboro wigitsina gore uyobowe na fluoroscopique. Umuyoboro wa femorale yegeranye noneho uhindurwamo ubunini bukwiye, hanyuma umusumari wa PFNA winjizwemo. Icyuma cyiziritse cyinjijwe mumutwe wigitsina gore, kandi uburyo bwo gufunga bukoreshwa mugitsina cya kure kugirango gitange umutekano.
6. Kwitaho nyuma yubuvuzi nyuma yo kubagwa kwa PFNA
Nyuma yo kubagwa imisumari ya PFNA, umurwayi ubusanzwe abikwa kuruhuka iminsi mike. Igihimba cyanduye ntigihagarikwa hamwe nigitereko cyangwa guteramo ibyumweru byinshi kugirango biteze imbere gukira. Umurwayi arasabwa kwirinda ibikorwa byo gutwara ibiro amezi make kugirango yemere gukira neza. Ubuvuzi bwumubiri busanzwe butangira hakiri kare kugirango tunoze urwego rwimikorere nimbaraga zimitsi.
7. Ingorane za PFNA nubuyobozi
Kimwe nuburyo ubwo aribwo bwose bwo kubaga, imisumari ya PFNA itwara ingaruka zimwe ningaruka zishobora kubaho. Izi ngorane zirimo kwandura, kunanirwa guterwa, gukomeretsa imitsi, gukomeretsa kw'amaraso, no kudahuza ubumwe. Nyamara, muri rusange igipimo cyingutu cya PFNA imisumari yimisumari ni mike. Gucunga ibyo bibazo mubisanzwe bikubiyemo kubaga gusubiramo cyangwa kuvura abagumyabanga, bitewe n'uburemere bwikibazo.
8. PFNA nizindi nzara zidasanzwe
Ugereranije nubundi bwoko bwimisumari yimbere, imisumari ya PFNA ifite ibyiza byinshi. Kimwe mu byiza byingenzi byimisumari ya PFNA nuburyo bwayo bwo kurwanya kuzunguruka, butanga ihindagurika ryumutwe wumugore. Iremera kandi kugabana imizigo hagati yimisumari nigufwa, bigabanya ibyago byo kunanirwa kwatewe. Umusumari wa PFNA nawo uroroshye kubyinjiza kandi ufite ibyago bike byo guhura nibibazo.
9. Ibyiza bya PFNA Imisumari idasanzwe
Imisumari ya PFNA ifite inyungu nyinshi kurenza ubundi buryo bwo kubaga bwo kuvura kuvunika ikibuno. Imwe mu nyungu zingenzi ningirakamaro zayo mukuvura imvururu zidahindagurika hamwe na subtrochanteric kuvunika ikibuno. Umusumari wa PFNA uremerera no gukanguka hakiri kare kandi ibitaro bigumaho ugereranije nubundi buryo bwo kubaga. Ifite kandi ibyago bike byo kunanirwa kwatewe kandi itanga umusaruro mwiza.
10. Ibibi bya PFNA Imisumari idasanzwe
Mugihe imisumari ya PFNA ifite ibyiza byinshi, nayo ifite ibibi. Imwe mu mbogamizi nyamukuru ni ingaruka zishobora gutera ibibazo, nko kunanirwa guterwa, kwandura, no gukomeretsa imitsi. Umusumari wa PFNA nawo uhenze ugereranije nubundi buryo bwo kubaga.

Ubushakashatsi bwerekanye ko imisumari ya PFNA ifite umusaruro ushimishije hamwe nitsinzi yo kuvura kuvunika ikibuno. Intsinzi yo gutera imisumari ya PFNA iri hagati ya 70% na 90%, hamwe nibikorwa byiza byavuzwe mubikorwa byinshi. Umusumari wa PFNA ufite kandi igipimo gito cyo kubaga ubugororangingo no kunanirwa kwatewe.
12. PFNA mu barwayi bakuze
Kuvunika ikibuno bikunze kugaragara mubantu bageze mu zabukuru, kandi imisumari ya PFNA yagaragaye nk'ubuhanga buzwi cyane bwo kubaga kuvura kuvunika ikibuno ku barwayi bakuze. Umusumari wa PFNA wagaragaye ko ufite umusaruro mwiza muri aba baturage, hamwe n’ikibazo gito cy’ibibazo ndetse no kumara igihe gito mu bitaro.
13. Iterambere ry'ejo hazaza
Imisumari ya PFNA yahinduwe inshuro nyinshi kuva yatangizwa, hagamijwe kunoza imikorere no kugabanya ingaruka zayo. Bimwe mubyahinduwe birimo impinduka muburyo bwa tekinike ya tekinike, kunoza uburyo bwo gufunga, no guhindura uburebure bwa misumari na diameter. Iterambere ryibikoresho bishya, nka titanium alloys nibikoresho biodegradable, nabyo birashakishwa kugirango imikorere yimisumari ya PFNA irangire.
14. Umwanzuro
Muri make, imisumari ya PFNA ni tekinike izwi cyane yo kubaga kuvura kuvunika ikibuno, cyane cyane mubantu bageze mu zabukuru. Umusumari wa PFNA utanga umusaruro mwiza, hamwe nigipimo gito cyibibazo no kumara igihe gito mubitaro. Ariko, kimwe nuburyo ubwo aribwo bwose bwo kubaga, butwara ingaruka zimwe ningaruka zishobora kubaho. Gutezimbere ibikoresho bishya no guhindura muburyo bwo gushushanya imisumari birashoboka kuzamura imikorere yimisumari ya PFNA mugihe kizaza.
