Kuvunika kw'agace k'inkari zo mu kibuno ka femur bingana na 50% by'imvune zo mu kibuno kandi ni bwo bwoko bukunze kugaragara cyane mu barwayi bageze mu za bukuru. Gufata inzara zo mu kibuno mu buryo bw'imbere ni cyo gipimo cy'agaciro cyo kuvura imvune zo mu kibuno. Hari ubwumvikane hagati y'abaganga b'inkari bwo kwirinda "ingaruka ngufi" bakoresheje inzara ndende cyangwa ngufi, ariko ubu nta bwumvikane buhari ku guhitamo hagati y'inzara ndende n'izigufi.
Mu by’ukuri, inzara ngufi zishobora kugabanya igihe cyo kubagwa, zikagabanya gutakaza amaraso, kandi ntizigabanye inzara, mu gihe inzara ndende zitanga uburimbane bwiza. Mu gihe cyo gushyira inzara, uburyo busanzwe bwo gupima uburebure bw’inzara ndende ni ugupima uburebure bw’agapira k’inyobora. Ariko, ubu buryo akenshi ntibuba bufite ukuri, kandi niba hari ukunyuranya k’uburebure, gusimbuza inzara zo mu nda bishobora gutuma amaraso menshi atakaza, kongera imvune zo kubagwa, no kongera igihe cyo kubagwa. Kubwibyo, niba uburebure busabwa bw’inzara zo mu nda bushobora gusuzumwa mbere yo kubagwa, intego yo gushyira inzara ishobora kugerwaho mu buryo bumwe, hirindwa ibyago byo kubagwa.
Kugira ngo bakemure iki kibazo cy’ubuvuzi, intiti z’abanyamahanga zakoresheje agasanduku ko gupfunyikamo inzara imbere y’umugongo (Agasanduku) kugira ngo bapime uburebure bw’inzara imbere y’umugongo hakoreshejwe fluoroscopy, byitwa "Ubuhanga bwo Gupfunyika". Ingaruka zo gukoresha ubuvuzi ni nziza, nk'uko tubisanga hano hepfo:
Ubwa mbere, shyira umurwayi ku gitanda cyo gukurura hanyuma ukore gahunda yo kugabanya umuvuduko ufunze ukoresheje imbaraga. Umaze kugabanya umuvuduko ushimishije, fata inzara y'imbere mu nda itarafungurwa (harimo n'agasanduku ko gupfunyikamo) hanyuma ushyire agasanduku ko gupfunyikamo hejuru y'ikirenge cyafashwe n'indwara:
Hakoreshejwe imashini ya C-arm fluoroscopy, icyerekezo cyo gushyira impera y’urukara rw’imbere mu kanwa ni uguhuza impera y’urukara rw’imbere mu kanwa n’agace k’imbere mu kanwa kari hejuru y’ijosi ry’ijosi hanyuma ukagashyira ku gice cy’imbere cy’urukara rw’imbere mu kanwa.
Iyo umwanya wo hafi ugeze ku rugero rwiza, komeza umwanya wo hafi, hanyuma usunike ukuboko kwa C werekeza ku mpera y'ivi hanyuma ukore fluoroscopy kugira ngo ubone ishusho nyayo y'ingingo y'ivi. Icyitonderwa cy'umwanya wo hagati ni urusobe rw'intercondylar rw'ivi. Simbuza ururabo rw'imbere ukoresheje uburebure butandukanye, ugamije kugera ku ntera iri hagati y'inkombe y'imbere y'ivi n'urusobe rw'imbere rw'ivi mu ntera ya diametre 1-3 z'urusobe rw'imbere. Ibi bigaragaza uburebure bukwiye bw'urusobe rw'imbere.
Byongeye kandi, abanditsi basobanuye imiterere ibiri yo gufotora ishobora kugaragaza ko urura rwo mu nda y'umugongo ari rurerure cyane:
1. Impera y'inyuma y'urukwi rw'imbere mu nda ishyirwa mu gice cya 1/3 cy'ubuso bw'ingingo ya patellofemoral (imbere mu murongo wera ku ishusho iri hepfo).
2. Impera y'inyuma y'umusumari wo mu nda y'umugongo ishyirwa mu mpandeshatu igizwe n'umurongo wa Blumensaat.
Abanditsi bakoresheje ubu buryo kugira ngo bapime uburebure bw'inzara zo mu nda ku barwayi 21, basanga ari 95.2%. Ariko, hashobora kubaho ikibazo muri ubu buryo: iyo inzara zo mu nda zishyizwe mu mubiri woroshye, hashobora kubaho ingaruka zo kongera ubwinshi mu gihe cyo gupima fluoroscopy. Ibi bivuze ko uburebure nyabwo bw'inzara zo mu nda zikoreshwa bushobora kuba bugufi gato ugereranije n'ibipimo byakozwe mbere yo kubagwa. Abanditsi babonye iki kintu ku barwayi bafite umubyibuho ukabije, maze bavuga ko ku barwayi bafite umubyibuho ukabije, uburebure bw'inzara zo mu nda zigomba kugabanywa mu rugero mu gihe cyo gupima cyangwa se bakamenya neza ko intera iri hagati y'inkombe y'inyuma y'inzara zo mu nda n'agace k'inyuma ...
Mu bihugu bimwe na bimwe, inzara zo mu bwoko bwa intramedullary zishobora gupfunyikwa ukwazo kandi zigashyirwamo imiti isanzwe, ariko mu bihe byinshi, uburebure butandukanye bw'inzara zo mu bwoko bwa intramedullary zivangwa hamwe kandi zigashyirwamo imiti isanzwe hamwe n'abakora imiti isanzwe. Kubera iyo mpamvu, bishobora kudashoboka gusuzuma uburebure bw'inzara zo mu bwoko bwa intramedullary mbere yo kuzishyiramo imiti isanzwe. Ariko, iki gikorwa gishobora kurangizwa nyuma y'uko amashuka yo kuzishyiramo imiti ashyizweho.
