Intera ya Arc Intera: Ishusho Ibipimo byo gusuzuma imurikagurisha rya Barton kuri palmar

Ibipimo bikunze gukoreshwa mugusuzuma imivurumu ya radiyo ya kure mubisanzwe harimo inguni ya taler (VTA), Ulnar itandukanye, nuburebure bwa radiyo. Mugihe imyumvire yacu kuri anatomiya ya radiyo ya marike yarushijeho kwimbitse, intera yinyongera nkintera ya anteroposteur (apd), kandi yifashishwa-kuri-radiyo (ikarita) yashyizwe mubikorwa byubuvuzi.

Mubisanzwe byakoreshejwe mugusuzuma ibicuruzwa bya Radiyo bya kure birimo: A: VTA; B: APD; C: TDA; D: Ikarita.

Ibipimo byinshi byerekana birakwiriye kuvunika indwara zidasanzwe za radiyo, nkuburebure bwa radiyo na ulnar itandukanye. Ariko, kubijyanye no kuvunika imiterere, nkibisobanuro bya Barton, ibipimo bya Barton, ibipimo gakondo gakondo birashobora kubura mubushobozi bwabo bwo kumenya neza ibimenyetso byo kubaga no gutanga ubuyobozi. Muri rusange byemezwa ko ibimenyetso byo kubaga kubijyanye no kuvuza ibihangano bifitanye isano rya hafi nintambwe yo hejuru. Kugira ngo hasuzugure urugero rwo kwimura ibicuruzwa bya Intra-Arcticular, intiti z'amahanga zasabye ibipimo bishya byo gupima: Tad (bivugwa bwa mbere ku bijyanye no kwimurwa na Polisi y'inyuma biherekejwe no kwimurwa kwa posteriolior.

Ku mpera za Tibia, mugihe cyo kuvunika inyuma ya Masterolus hamwe no kugabanuka inyuma ya Talus, hejuru yimpande eshatu: ARC 1 niyo gari ihuriweho na pariteri yinyuma, na ARC 3 iri hejuru ya Talus. Iyo habaye igice cyo gucika cya MalLeolus kiherekejwe nimbuga inyuma ya Talus, hagati yuruziga rwakozwe na ARC 1 hejuru ya Trions yanditsweho na ARC. Kuringaniza

Intego yo kubaga ni ukugera kuri ATD (TILD nyuma yo kwimurwa) agaciro ka 0, byerekana kugabanya anatomique yubuso bwuzuye.

Mu buryo nk'ubwo, ku bijyanye n'ivunika rya Volar Barton:

Ibice byo hejuru igice cyibice bigize arc 1.

Umudozi yijimye akora nka arc 2.

Ikintu cya Drisal cya Radiyo (igufwa risanzwe ridafite amakuru) ryerekana ARC 3.

Buri kimwe muri ibyo arcs kirashobora gufatwa nkinziga. Kubera ko ibice by'ibiciro hamwe n'igice cy'ijwi bimuwe hamwe, kuzenguruka 1 (mu muhondo) bisangiye ikigo cyayo hamwe n'uruziga 2 (yera). ACD yerekana intera iri hagati yiyi kigo gisangiwe hagati yumuzingi 3. Intego yo kubaga ni ukugarura acd kuri 0, byerekana kugabanuka kwa Anatomical.

Mu myitozo yakozwe, yemerwa cyane ko hejuru yintambwe ya <2mm ni urwego rwo kugabanya. Ariko, muri ubu bushakashatsi, uwakiriye aranga (ROC) umurongo uhuza ibipimo bitandukanye byamafoto byerekanaga ko ACD ifite ahantu hirengeye munsi yumurongo (Auc). Gukoresha agaciro ka Cuttoff wa 1.02mm kuri ACD, yerekanaga ibitekerezo 100% na 80.95%. Ibi byerekana ko mugikorwa cyo kugabanya amakuru, kugabanya acd kugeza muri 1.02mm birashobora kuba ibipimo byiza

kuruta ibipimo gakondo bya <2mm hejuru yinyuma.

Acd isa nkaho ifite akamaro kagereranijwe yo gusuzuma urwego rwo kwimurwa muburyo bwo kuvura bukubiyemo ingingo zirimo ingingo. Usibye gusaba kwayo mugusuzuma imiti yisi hamwe na radiyo ya kure nkuko byavuzwe haruguru, ACD nayo irashobora gukoreshwa mugusuzuma inkoni. Ibi bitanga abakora ubuvuzi hamwe nigikoresho cyingirakamaro cyo guhitamo kwivuza no gusuzuma ibisubizo byo kugabanya.
