Ukuphuka kwelunga leqakala okubangelwa amandla ajikelezayo noma aqondile, njengokuphuka kwePilon, kuvame ukubandakanya i-posterior malleolus. Ukuvezwa kwe-"posterior malleolus" okwamanje kufezwa ngezindlela ezintathu eziyinhloko zokuhlinzwa: indlela engemuva engemuva, indlela engemuva engemuva, kanye nendlela eguquliwe ye-posterior medial. Kuye ngohlobo lokuphuka kanye nesimo sezingcezu zamathambo, kungakhethwa indlela efanelekile. Izazi zakwamanye amazwe zenze izifundo zokuqhathanisa ububanzi bokuvezwa kwe-posterior malleolus kanye nokucindezeleka ezinqeni zemithambo yegazi nezezinzwa zelunga leqakala elihambisana nalezi zindlela ezintathu.

ezinqeni zemithambo yegazi kanye nezezinzwa zelunga leqakala ezihambisana nalezi zindlela ezintathu.
1. Indlela Yokubuka Okuphakathi Kwangemuva
Indlela yokuxhumana engemuva ihilela ukungena phakathi kwe-flexor ende yezinzwane kanye nemithambo ye-tibial yangemuva. Le ndlela ingaveza u-64% we-posterior malleolus. Ukucindezeleka ezinqeni zemithambo yegazi kanye nezezinzwa ohlangothini lwale ndlela kulinganiswa ku-21.5N (19.7-24.1).
▲ Indlela Yokubhekana Nezinzwane Ezingemuva (Umcibisholo Ophuzi). 1. I-tendon ye-tibial engemuva; 2. I-tendon ende egoqekayo yezinzwane; 3. Imithambo ye-tibial engemuva; 4. I-nerve ye-tibial; 5. I-tendon ye-Achilles; 6. I-tendon ye-hallucis longus egoqekayo. I-AB=5.5CM, ububanzi bokuchayeka kwe-posterior malleolus (AB/AC) bungu-64%.
2. Indlela Yokubheka Ngasemuva
Indlela engemuva ehlangothini ihilela ukungena phakathi kwemisipha ye-peroneus longus kanye ne-brevis kanye nemisipha ye-flexor hallucis longus. Le ndlela ingaveza u-40% we-posterior malleolus. Ukucindezeleka ezinqeni zemithambo yegazi kanye nezezinzwa ohlangothini lwale ndlela kulinganiswa ku-16.8N (15.0-19.0).
▲ Indlela Yokubhekana Nezinzwane Ezingemuva (Umcibisholo Ophuzi). 1. I-tendon ye-tibial engemuva; 2. I-tendon ende egoqekayo yezinzwane; 4. Imithambo ye-tibial engemuva; 4. I-nerve ye-tibial; 5. I-tendon ye-Achilles; 6. I-tendon ye-hallucis longus egoqekayo; 7. I-tendon ye-Peroneus brevis; 8. I-tendon ye-Peroneus longus; 9. I-vein encane ye-saphenous; 10. I-nerve evamile ye-fibular. I-AB=5.0CM, ububanzi bokuchayeka kwe-posterior malleolus (BC/AB) bungu-40%.
3. Indlela Eguquliwe Ye-Posterior Medial
Indlela yokuguqula indlela yokuxhumana yangemuva ihilela ukungena phakathi kwe-tibial nerve kanye ne-flexor hallucis longus tendon. Le ndlela ingaveza u-91% we-posterior malleolus. Ukucindezeleka kuma-bundle emithambo yegazi kanye ne-neural ohlangothini lwale ndlela kulinganiswa ku-7.0N (6.2-7.9).
▲ Indlela Eguquliwe Yokugudluzwa Kwangemuva (Umcibisholo Ophuzi). 1. I-tendon ye-tibial yangemuva; 2. I-tendon ende egoqekayo yezinzwane; 3. Imithambo ye-tibial yangemuva; 4. I-nerve ye-tibial; 5. I-tendon ye-hallucis longus egoqekayo; 6. I-tendon ye-Achilles. I-AB=4.7CM, ububanzi bokuchayeka kwe-posterior malleolus (BC/AB) bungu-91%.
