Ama-46% okujikeleza ama-ankle fracties ahambisana nokuqhekeka kwangemuva kwe-maryears. Indlela ye-POSTERELANALS yokubuka okuqondile kanye nokulungiswa kwe-malleolus yangemuva kuyindlela evame ukusetshenziswa ngokuhlinza, okunikeza izinzuzo ezingcono ze-biomechanical ngokuqhathaniswa nokulungiswa okuvaliwe kanye nokulungiswa kwesikulufa se-antteroposteror. Kodwa-ke, ngezingcezwana ezinkulu zangemuva zokuqhekeka ezingemuva noma ezingemuva kwe-malleolar fractures ezibandakanya i-colticulus yangemva kwe-malleolus ye-medial, indlela eyisibonelo ihlinzeka ngombono ongcono wokuhlinzwa.
Ukuqhathanisa ububanzi bokuvezwa kwe-malleolus ngemuva, ukungezwani esikhwameni se-neurovascular, kanye nebanga phakathi kokuvela kanye nesigaxa se-neurovascular ezindleleni ezintathu ezihlukile zezibuko, abacwaningi benze isifundo se-cadaveric. Imiphumela isanda kushicilelwa kwi-FAS Journal. Okutholakele kufingqiwe kanjena:
Njengamanje, kunezindlela ezintathu eziphambili ze-postemedial zokudalula i-malleolus yangemuva:
1
2. I-Modified PosteMedial Indlela (i-Mopm): Le ndlela ingena phakathi kweTibialis Preterior Tendon kanye ne-Flexer Digiitorum Longus Tendon (isithombe 1 sibonisa iTibialis posterior tendon, futhi isithombe 2 sibonisa i-Flexer Digiitorum Longes Longuus Tendon).
3. Indlela yePosteMedial (PM): Le ndlela ingena phakathi komphetho we-medial we-Achilles Tendon kanye ne-Flevel Hallucis Longus Tendon (Umdwebo 3 ikhombisa i-Achilles Tendon, futhi isithombe 4 sibonisa i-Flevel Hallucis Longus Hellos Tendon).
Ngokuphathelene nokungezwani kwesigaxa se-neurovascular, indlela ye-PM inokungezwani okuphansi ku-6.18n ngokuqhathaniswa ne-mepm ne-mopm isondela ekulimaleni okunamandla kwe-neurovascular.
Ngokwezinga lokuvezwa kwe-malleolus yangemuva, indlela ye-PM futhi inikeza ukubonakaliswa okukhulu, okuvumela ukubonakala okungu-71% kwe-malleolus ngemuva. Uma kuqhathaniswa, izindlela ze-MEPM ne-MOPM zivumela ukuvezwa okungu-48.5% no-57% kaMalleolus wangemuva, ngokulandelana.
● Umdwebo ukhombisa ukwahlulwa kokuvezwa kwe-malleolus ngemuva kwezindlela ezintathu. I-AB imele ububanzi be-malleolus ephelele, i-CD imele ibanga eliveziwe, kanye ne-CD / AB yisilinganiso sokuvezwa. Ukusuka phezulu kuya phansi, amabanga okuvezwa kwe-mepm, i-mopm, futhi kuboniswe i-PM. Kuyabonakala ukuthi indlela ye-PM inebanga elikhulu kakhulu lokuvezwa.
Ngokuphathelene nebanga phakathi kwe-incision kanye nenqwaba ye-neurovascular, indlela ye-PM nayo inebanga elikhulu kunawo wonke, elinganisa 25.5mm. Lokhu kukhulu kune-mepm's 17.25mm kanye ne-mopm's 7.5mm. Lokhu kubonisa ukuthi indlela ye-PM inethuba eliphansi kakhulu lokulimala kwe-neurovascular pumps ngesikhathi sokuhlinzwa.
● Umdwebo ukhombisa amabanga phakathi kwe-incision kanye nenqwaba ye-neurovascular yezindlela ezintathu. Ukusuka kwesobunxele uye kwesokudla, amabanga amade we-mepm, i-mopm, kanye nezindlela ze-PM zibonisiwe. Kuyabonakala ukuthi indlela ye-PM inebanga elikhulu kunawo wonke kusuka kwinqwaba ye-neurovascular.
