Kuvunika kwa Tibial shaft ni ibikomere bisanzwe byubuvuzi. Intramedullary yimisumari yimbere ifite ibyiza bya biomehanike yo kugabanura byoroheje na axial fixation, bigatuma iba igisubizo gisanzwe cyo kuvura kubaga. Hariho uburyo bubiri bwingenzi bwo gutera imisumari kugirango tibial intramedullary ikosore imisumari: suprapatellar na infrapatellar imisumari, hamwe nuburyo bwa parapatellar bwakoreshejwe nintiti zimwe.
Kubuvunika bwa hafi ya 1/3 cya tibia, kubera ko uburyo bwa infrapatellar busaba guhindagurika kw'ivi, biroroshye gutera kuvunika kugana imbere mugihe cyo kubaga. Kubwibyo, uburyo bwa suprapatellar busanzwe busabwa kuvurwa.
Ishusho yerekana ishyirwaho ryingingo zanduye binyuze muburyo bwa suprapatellar
Ariko, niba hari ibibuza uburyo bwa suprapatellar, nkibisebe byoroheje byoroheje, bigomba gukoreshwa. Nigute wakwirinda kurakara kurangiza kuvunika mugihe cyo kubagwa nikibazo kigomba guhura nacyo. Intiti zimwe zikoresha ibyuma bito bito kugirango bikosore by'agateganyo cortex y'imbere, cyangwa bagakoresha imisumari yo guhagarika kugirango bakosore uburakari.
Shows Ishusho yerekana ikoreshwa ryo guhagarika imisumari kugirango ukosore inguni.
Kugira ngo iki kibazo gikemuke, intiti z’amahanga zakoresheje tekinike yo gutera. Iyi ngingo iherutse gusohoka mu kinyamakuru "Ann R Coll Surg Engl":
Hitamo imigozi ibiri ya 3.5mm y'uruhu, yegereye isonga ryumutwe wacitse, shyiramo umugozi umwe imbere n'inyuma mubice byamagufwa kumpande zombi zavunitse, hanyuma usige ibirenga 2cm hanze yuruhu:
Fata imbaraga zo kugabanya kugirango ukomeze kugabanuka, hanyuma ushyiremo imisumari yimbere ukurikije inzira zisanzwe. Nyuma yo gushiramo umusumari winjiye, kura umugozi.
Ubu buryo bwa tekiniki burakwiye kubibazo bidasanzwe aho inzira ya suprapatellar cyangwa parapatellar idashobora gukoreshwa, kandi ntibisanzwe. Ishyirwa ryiyi screw rishobora kugira ingaruka kumyanya yimisumari nkuru, cyangwa hashobora kubaho ibyago byo kumeneka. Irashobora gukoreshwa nkibisobanuro mubihe bidasanzwe.
