Ukuphuka kwejoyinti le-ankle okubangelwa amandla ajikelezayo noma aqondile, njenge-Pilon fractures, ngokuvamile kuhilela i-posterior malleolus. Ukuvezwa kwe-"posterior malleolus" okwamanje kufinyelelwa ngezindlela ezintathu eziyinhloko zokuhlinzwa: indlela ye-posterior lateral, indlela ye-posterior medial, kanye nendlela ye-posterior medial eguquliwe. Kuye ngohlobo lokuphuka kanye ne-morphology yezingcezu zamathambo, indlela efanelekile ingakhethwa. Izazi zakwamanye amazwe zenze izifundo zokuqhathanisa ngebanga lokuchayeka kwe-posterior malleolus kanye nokushuba kwemithambo yemithambo nemithambo yemizwa yelunga leqakala elihambisana nalezi zindlela ezintathu.

kuma-vascular and neural bundles we-ankle joint ehambisana nalezi zindlela ezintathu.
1. Indlela Yangemuva Ephakathi
Indlela ye-posterior medial ihilela ukungena phakathi kwe-flexor ende yezinzwane kanye nemikhumbi ye-posterior tibial. Le ndlela ingadalula u-64% we-posterior malleolus. Ukungezwani kwezinqwaba zemithambo kanye nezinzwa ohlangothini lwale ndlela kukalwa ku-21.5N (19.7-24.1).
▲ Indlela Yangemuva Emaphakathi (Umcibisholo Ophuzi). 1. Umsipha we-posterior tibial; 2. Umthambo omude oguquguqukayo wezinzwani; 3. Imikhumbi ye-posterior tibial; 4. I-Tibial nerve; 5. Umsipha we-Achilles; 6. I-Flexor hallucis longus tendon. AB=5.5CM, ibanga lokuchayeka ngemuva kwe-malleolus (AB/AC) lingu-64%.
2. Indlela Yangemuva Engemuva
Indlela ye-posterior lateral ihilela ukungena phakathi kwe-peroneus longus ne-brevis tendon kanye ne-flexor hallucis longus tendon. Le ndlela ingadalula u-40% we-posterior malleolus. Ukungezwani kwemithambo yegazi nemithambo yegazi ohlangothini lwale ndlela kukalwa ku-16.8N (15.0-19.0).
▲ Indlela Engemuva Kwasemuva (Umcibisholo Ophuzi). 1. Umsipha we-posterior tibial; 2. Umthambo omude oguquguqukayo wezinzwani; 4. Izitsha ze-posterior tibial; 4. I-Tibial nerve; 5. Umsipha we-Achilles; 6. I-Flexor hallucis longus tendon; 7. I-Peroneus brevis tendon; 8. Umsipha we-Peroneus longus; 9. Umthambo omncane we-saphenous; 10. I-fibular nerve evamile. AB=5.0CM, i-posterior malleolus exposure range (BC/AB) ingu-40%.
3. Indlela Ephakathi Engasemva Eguquliwe
Indlela ye-posterior medial eguquliwe ihilela ukungena phakathi kwe-tibial nerve kanye ne-flexor hallucis longus tendon. Le ndlela ingadalula u-91% we-posterior malleolus. Ukungezwani kwe-vascular kanye ne-neural bundles ohlangothini lwale ndlela kulinganiswa ku-7.0N (6.2-7.9).
▲ Indlela Emaphakathi Engemuva Eguquliwe (Umcibisholo Ophuzi). 1. Umsipha we-posterior tibial; 2. Umthambo omude oguquguqukayo wezinzwani; 3. Imikhumbi ye-posterior tibial; 4. I-Tibial nerve; 5. I-Flexor hallucis longus tendon; 6. I-Achilles tendon. AB=4.7CM, ibanga lokuchayeka ngemuva kwe-malleolus (BC/AB) lingu-91%.
