Ukuqhekeka kwelungu leqakala okubangelwa ngamandla ajikelezayo okanye athe nkqo, njengokwaphuka kwePilon, kudla ngokubandakanya i-posterior malleolus. Ukuvezwa kwe-"posterior malleolus" ngoku kufezekiswa ngeendlela ezintathu eziphambili zotyando: indlela engasemva ecaleni, indlela engasemva ephakathi, kunye nendlela eguqulweyo engasemva ephakathi. Ngokuxhomekeke kuhlobo lokuqhekeka kunye nokwakheka kweziqwenga zamathambo, indlela efanelekileyo inokukhethwa. Iingcali zamanye amazwe zenze izifundo zokuthelekisa uluhlu lokutyhileka kwe-posterior malleolus kunye noxinzelelo kwiibhanti zemithambo yegazi kunye nezemithambo-luvo zelungu leqakala ezinxulumene nezi ndlela zintathu.

Ukuvezwa kwe-"posterior malleolus" ngoku kufezekiswa ngeendlela ezintathu eziphambili zotyando: indlela engasemva ecaleni, indlela engasemva kwe-medial, kunye nendlela eguqulweyo ye-posterior medial. Ngokuxhomekeke kuhlobo lokuqhekeka kunye nokwakheka kweziqwenga zamathambo, indlela efanelekileyo inokukhethwa. Iingcali zamanye amazwe zenze izifundo zokuthelekisa uluhlu lokutyhileka kwe-posterior malleolus kunye noxinzelelo.
kwiimfumba zemithambo-luvo nezemithambo-luvo zelungu leqakala ezinxulumene nezi ndlela zintathu.
1. Indlela Yokuchukumisa Engasemva
Indlela yokungena emva kwe-medial ibandakanya ukungena phakathi kwe-long flexor yeenzwane kunye nemithambo ye-posterior tibial. Le ndlela inokuveza i-64% ye-posterior malleolus. Uxinzelelo kwi-vascular kunye ne-neural bundles ecaleni kwale ndlela lulinganiswa kwi-21.5N (19.7-24.1).
▲ Indlela Yokusebenzisa I-Posterior Medial (Utolo Olutyheli). 1. I-Posterior tibial tendon; 2. I-long flexor tendon yeenzwane; 3. Imithambo ye-posterior tibial; 4. I-Tibial nerve; 5. I-Achilles tendon; 6. I-flexor hallucis longus tendon. AB=5.5CM, uluhlu lokuvezwa kwe-posterior malleolus (AB/AC) yi-64%.
2. Indlela Yokujonga Ngasecaleni Kwangasemva
Indlela engasemva ecaleni ibandakanya ukungena phakathi kwe-peroneus longus kunye ne-brevis tendons kunye ne-flexor hallucis longus tendon. Le ndlela ingatyhila i-40% ye-posterior malleolus. Uxinzelelo kwi-vascular kunye ne-neural bundles ecaleni kwale ndlela lulinganiswa kwi-16.8N (15.0-19.0).
▲ Indlela Yokujika Ngasemva (Utolo Olutyheli). 1. I-tendon ye-tibial yangasemva; 2. I-tendon ende egobileyo yeenyawo; 4. Imithambo ye-tibial yangasemva; 4. I-nerve ye-tibial; 5. I-tendon ye-Achilles; 6. I-tendon ye-hallucis longus egobileyo; 7. I-tendon ye-Peroneus brevis; 8. I-tendon ye-Peroneus longus; 9. I-vein encinci ye-saphenous; 10. I-nerve eqhelekileyo ye-fibular. AB=5.0CM, uluhlu lokuvezwa kwe-posterior malleolus (BC/AB) yi-40%.
3. Indlela Eguquliweyo Ye-Posterior Medial
Indlela yokuguqula indlela yokungena engasemva ibandakanya ukungena phakathi kwe-tibial nerve kunye ne-flexor hallucis longus tendon. Le ndlela ingatyhila i-91% ye-posterior malleolus. Uxinzelelo kwi-vascular kunye ne-neural bundles ecaleni kwale ndlela lulinganiswa kwi-7.0N (6.2-7.9).
▲ Indlela Eguquliweyo Yokujika Kwangasemva (Utolo Olutyheli). 1. I-tendon ye-tibial yangasemva; 2. I-tendon ende egobileyo yezinzwane; 3. Imithambo ye-tibial yangasemva; 4. I-nerve ye-tibial; 5. I-tendon ye-hallucis longus egobileyo; 6. I-tendon ye-Achilles. AB=4.7CM, uluhlu lokuchaphazeleka kwe-posterior malleolus (BC/AB) yi-91%.
