Muburyo bugenda bwiyongera bwubuvuzi bwamagufwa, guhitamo kwimikwa bigira uruhare runini mugutsinda kubaga, cyane cyane mubibazo bivunika.
Mu bisubizo bifatika biboneka muri iki gihe harimo gufunga ibyubaka anatomiki ya 120 ° isahani, igikoresho cyakozwe mu buryo bwihariye kugira ngo gikemure ibibazo by’imiterere igoye cyane cyane mu turere twa pelvic na acetabular.
Igishushanyo mbonera cyateganijwe kugirango Amagufwa meza abeho
Kimwe mu bintu by'ingenzi biranga igufunga kwiyubaka anatomiki 120 ° isahanini imiterere yabanjirije imiterere. Bitandukanye nibisahani bisanzwe bigororotse bisaba kunama gukomeye, iyi sahani yabanje gukorwa kugirango ihuze ubugororangingo busanzwe bwamagufwa yagenewe, nka pelvic brim cyangwa ilium. Ibi bigabanya gukenera intoki mugihe cyo kubagwa, guta igihe no kugabanya ibyago byo kunanirwa nisahani cyangwa kudahuza.
Kubaganga babaga amagufwa, isahani isanzwe ihuza ubuso bwamagufwa itanga uburyo bwiza bwo guhuza umubiri, buteza imbere ituze kandi bikazamura ingaruka zo gukira. Ubushakashatsi bwerekanye ko amasahani yabanjirije ashobora kugabanya igihe cyo kubaga kugera kuri 20% kandi bikagabanya ihahamuka ryoroshye kubera guhuza neza.
120° Inguni: Yashizweho kuri Geometrike igoye
Inguni ya 120 ° yashyizwe mubishushanyo bifite agaciro cyane cyane mubice byavunitse aho isahani isanzwe igwa. Iyi mfuruka ifasha abaganga gukemura ibibazo byinshi byavunitse, cyane cyane bigira ingaruka kuri acetabulum cyangwa iliac crest, aho umurongo usanzwe hamwe no gutandukana kwa anatomique.
Iyi nguni yubatswe nayo ifasha mukubungabunga geometrie yifuzwa kandi ikanemeza ko imigozi yo gufunga ishobora kwerekezwa neza mumagufwa yo mu bwoko bwa cortical yo mu rwego rwo hejuru, kongera umutekano muke no kugabanya ibyago byo kurekura imigozi.
Gufunga Uburyo bwo Gukosora Rigid
Isahani ikubiyemo uburyo bwo gufunga imigozi, itanga inguni ihamye ningirakamaro kumagufwa yagabanijwe cyangwa osteoporotic. Imigaragarire yo gufunga hagati yisahani hamwe na screw ihindura ibyubaka muburyo bukosora imbere, bigabanya micro-moteri kumwanya wavunitse kandi bigateza imbere gukanguka no gukira amagufwa byihuse.
By'umwihariko, iyo ikoreshejwe mu iyubakwa rya pelvic cyangwa acetabular, tekinoroji yo gufunga yerekanye igipimo cyo kugabanuka no kunoza ibinyabuzima bikoresha ingufu mu turere twikorera ibiro.
Kunoza imikorere ya Surgical hamwe nibisubizo
Ku matsinda yo kubaga, igikoresho gihuza anatomiki ikwiranye no gufunga ituze bisobanura guhinduranya akazi no guhindura bike mubikorwa. Kugabanuka gukenera kunama cyangwa kuvugurura ntibigabanya gusa igihe cyo gukora ahubwo binagabanya impinduka zishobora kuba zisahani, zishobora kubangamira imbaraga zatewe.
Byongeye kandi, umukino mwiza wa anatomique utezimbere muri rusange guhuza amasahani-amagufwa, ari ngombwa mugusangira imitwaro no gutuza igihe kirekire, cyane cyane kubarwayi bakeneye cyane.
Porogaramu Kurenga Imanza Zimenetse
Gufunga kwiyubaka anatomical 120 ° isahani ikoreshwa muri:
Ivunika rya pelvic na acetabular
Iliac ibaba ryubaka
Kugabanuka kuvunika amagufwa maremare hamwe no guhindagurika
Ivunika rya periprosthetic
Guhindura byinshi hamwe no guhuza anatomique bituma ihitamo neza kubigo byihungabana byamagufwa, cyane cyane mubihe bigoye cyane aho usanga ari byo byingenzi.
Mugihe uvura kuvunika bigoye, cyane cyane mukarere katoroshye nka pelvis cyangwa acetabulum, ibintu byashizweho. Gufunga kwiyubaka kwa anatomiki 120 ° isahani itanga uburinganire bwuzuye bwimiterere yabanjirije iyambere, itajegajega, hamwe no gukosora - byongera uburyo bwo kubaga no kuvura abarwayi.
Niba ushaka uburyo bwizewe, bworohereza abaganga bwagenewe gukenera ibintu byubaka, Ubuvuzi bwa Shuangyang butanga ibyapa byujuje ubuziranenge bwa 120 ° byakozwe kugirango byuzuze amahame akomeye y’ubuvuzi kandi bikwiranye n’ibisabwa kwa muganga.
