Ubuhanga bwo kubaga | Uburyo butatu bwo kubaga bwo kwerekana "Posterior Malleolus"

Kuvunika kw'ibirenge biterwa n'imbaraga zizunguruka cyangwa zihagaritse, nk'imvune za Pilon, akenshi zirimo malleolus inyuma. Kugaragara kwa "posterior malleolus" kuri ubu bigerwaho binyuze muburyo butatu bwo kubaga: inzira yinyuma yinyuma, inzira yo hagati yinyuma, hamwe nuburyo bwahinduwe bwimbere. Ukurikije ubwoko bwavunitse hamwe na morphologie yibice byamagufwa, inzira nziza irashobora guhitamo. Intiti z’amahanga zakoze ubushakashatsi bugereranya ku bijyanye n’imiterere ya malleolus yinyuma hamwe n’imivurungano ku mitsi n’imitsi iva mu maguru ifatanye n’uburyo butatu.

1. Inzira Yinyuma Hagati

Uburyo bwo hagati bwinyuma burimo kwinjiza hagati yimiterere miremire yinono hamwe nimiyoboro yinyuma. Ubu buryo bushobora kwerekana 64% ya malleolus yinyuma. Impagarara zifata imitsi nu mitsi kuruhande rwubu buryo bupimirwa kuri 21.5N (19.7-24.1).

Appro Inzira Yinyuma Hagati (Umwambi w'umuhondo). 1. Inyuma ya tibial tendon; 2. Umuyoboro muremure w'amano. 3. Imitsi yinyuma yinyuma; 4. Imitsi ya Tibial; 5. Achilles tendon; 6. Flexor hallucis longus tendon. AB = 5.5CM, inyuma ya malleolus yerekana (AB / AC) ni 64%.

2. Inzira yinyuma

Inzira yinyuma yinyuma ikubiyemo kwinjira hagati ya peroneus longus na brevis tendon na flexor hallucis longus tendon. Ubu buryo bushobora kwerekana 40% ya malleolus yinyuma. Impagarara zifata imitsi nu mitsi kuruhande rwubu buryo bupimirwa kuri 16.8N (15.0-19.0).

Ach Inzira Yinyuma Yegereye (Umwambi w'umuhondo). 1. Inyuma ya tibial tendon; 2. Umuyoboro muremure w'amano. 4. Imitsi yinyuma yinyuma; 4. Imitsi ya Tibial; 5. Achilles tendon; 6. Flexor hallucis longus tendon; 7. Peroneus brevis tendon; 8. Peroneus longus tendon; 9. Imitsi mito mito; 10. Imitsi isanzwe ya fibular. AB = 5.0CM, inyuma ya malleolus yerekana (BC / AB) ni 40%.

3. Byahinduwe Byimbere Hagati Hagati

Uburyo bwahinduwe bwimbere bwo hagati burimo kwinjiza hagati ya tibial nervice na flexor hallucis longus tendon. Ubu buryo bushobora kwerekana 91% ya malleolus yinyuma. Impagarara zifata imitsi nu mitsi kuruhande rwubu buryo bupimirwa kuri 7.0N (6.2-7.9).
