Uburyo bwo Kubaga | Uburyo Butatu bwo Kubaga bwo Kugaragaza "Posterior Malleolus"

Kuvunika kw'ingingo y'akaguru biterwa n'imbaraga zizenguruka cyangwa zihagaze, nka kuvunika kwa Pilon, akenshi biba bifitanye isano na malleolus y'inyuma. Kugaragara kwa "malleolus y'inyuma" ubu bigerwaho binyuze mu buryo butatu bw'ingenzi bwo kubaga: uburyo bwo ku ruhande rw'inyuma, uburyo bwo ku ruhande rw'inyuma, n'uburyo bwo kuvura inyuma. Bitewe n'ubwoko bw'imvune n'imiterere y'ibice by'amagufwa, uburyo bukwiye bushobora gutoranywa. Intiti z'abanyamahanga zakoze ubushakashatsi bugereranya urwego rw'ishusho ya malleolus y'inyuma n'umuvuduko ku mitsi n'imitsi yo mu kaguru ijyanye n'ubu buryo butatu.

Gucika kw'ingingo y'akaguru biterwa n'imbaraga zizenguruka cyangwa zihagaze, nka Pilon fracture, akenshi biba bifitanye isano na posterior malleolus. Kugaragara kwa "posterior malleolus" ubu bigerwaho binyuze mu buryo butatu bw'ingenzi bwo kubaga: posterior lateral approach, posterior medial approach, na modified posterior medial approach. Bitewe n'ubwoko bw'imvune n'imiterere y'ibice by'amagufwa, uburyo bukwiye bushobora gutoranywa. Intiti z'abanyamahanga zakoze ubushakashatsi bugereranya urwego rw'isura ya posterior malleolus n'umuvuduko wayo.

ku mitsi n'imitsi yo mu kaguru bifitanye isano n'ubu buryo butatu.

1. Uburyo bwo gupima inyuma

Uburyo bwo kwinjira hagati y'amano y'inyuma burimo kwinjira hagati y'uburyo bwo kongerera amaguru n'imitsi y'inyuma y'ikirenge. Ubu buryo bushobora kugaragaza 64% bya malleolus y'inyuma. Umuvuduko ku mitsi n'imitsi yo mu bwonko ku ruhande rw'ubu buryo upimirwa kuri 21.5N (19.7-24.1).

▲ Uburyo bwo guhagarara inyuma (Umwambi w'umuhondo). 1. Umutsi w'inyuma wa tibial; 2. Umutsi muremure wo guhagarara ku mano; 3. Imitsi y'inyuma ya tibial; 4. Udutsi tw'inyuma; 5. Umutsi w'ikibuno; 6. Umutsi w'inyuma wa hallucis longus. AB = 5.5CM, intera yo guhagarara inyuma ya malleolus (AB / AC) ni 64%.

2. Uburyo bwo kuzenguruka inyuma

Uburyo bwo ku ruhande rw'inyuma burimo kwinjira hagati y'imitsi ya peroneus longus na brevis hamwe n'imitsi ya flexor hallucis longus. Ubu buryo bushobora kugaragaza 40% bya malleolus y'inyuma. Umuvuduko ku mitsi n'imitsi ku ruhande rw'ubu buryo upimirwa kuri 16.8N (15.0-19.0).

▲ Uburyo bwo kugabanya amaguru (Umwambi w'umuhondo). 1. Umutsi w'inyuma wa tibial; 2. Umutsi muremure wo kugabanya amaguru; 4. Imitsi yo mu gice cy'inyuma cya tibial; 4. Udutsi two mu gice cy'inyuma cya tibial; 5. Umutsi w'ikirenge wa Achilles; 6. Umutsi w'inyuma wa hallucis longus; 7. Umutsi w'inyuma wa Peroneus brevis; 8. Umutsi w'inyuma wa Peroneus longus; 9. Umutsi muto wa saphenous; 10. Udutsi dusanzwe twa fibula. AB = 5.0CM, intera yo kugaragaraho malleolus inyuma (BC / AB) ni 40%.

3. Uburyo bwo gupima inyuma bwahinduwe

Uburyo bwo gupima inyuma buhindura uburyo bwo gupima inyuma burimo kwinjira hagati y’imitsi yo mu gice cy’imbere cy’umugongo n’umutsi wo mu gice cy’imbere cy’umugongo wa hallucis longus. Ubu buryo bushobora kugaragaza 91% bya malleolus yo inyuma. Umuvuduko ku mitsi n’imitsi yo mu bwonko ku ruhande rw’ubu buryo upimirwa kuri 7.0N (6.2-7.9).

▲ Uburyo bwo gupima inyuma (Umwambi w'umuhondo) bwahinduwe. 1. Umutsi w'inyuma wa tibial; 2. Umutsi muremure wo gupima amano; 3. Imitsi yo mu gice cy'inyuma cya tibial; 4. Imitsi yo mu gice cy'inyuma; 5. Umutsi wo mu gice cy'inyuma cya hallucis longus; 6. Umutsi wo mu gice cy'inyuma cya AB = 4.7CM, intera yo gupima inyuma ya malleolus (BC / AB) ni 91%.
