Parizvino, iyo inonyanya kushandiswa yekuvhiya nzira yecalcaneal fractures inosanganisira kugadzirisa kwemukati nendiro uye screw kuburikidza ne sinus tarsi yekupinda nzira.Iyo lateral "L" yakaumbwa yakawedzera nzira haichafarirwa mukuita kwekiriniki nekuda kwepamusoro-nemaronda-ane hukama.Iyo ndiro uye screw system fixation, nekuda kweiyo biomechanical maitiro eeccentric fixation, inotakura njodzi yepamusoro yevarus malalignment, nezvimwe zvidzidzo zvinoratidza mukana wepashure wekuvhiya kwechipiri varus inosvika 34%.
Nekuda kweizvozvo, vaongorori vakatanga kudzidza intramedullary fixation nzira dzecalcaneal fractures kugadzirisa zvese zvine chekuita nemaronda uye nyaya yechipiri varus malalignment.
01 Nail central nailing technique
Iyi tekinoroji inogona kubatsira mukudzikisira kuburikidza ne sinus tarsi yekupinda nzira kana pasi pekutungamira kwearthroscopic, ichida kuderera kwenyama yakapfava kudiwa uye zvinogona kuderedza nguva yekuchipatara.Iyi nzira inoshandiswa pakusarudza II-III fractures, uye kune yakaoma comminuted calcaneal fractures, inogona kusapa kugadzirisa kwakasimba kwekuderedza uye ingada kuwedzera screw fixation.
02 Single-ndege intramedullary chipikiri
Iyo imwe-ndege intramedullary chipikiri inoratidzira maviri screws kuproximal uye distal end, ine mhango huru chipikiri inobvumira pfupa kubatanidzwa kuburikidza nembambo huru.
03 Multi-ndege intramedullary chipikiri
Yakagadzirwa zvichibva patatu-dimensional structural morphology yecalcaneus, iyi yemukati yekugadziridza sisitimu inosanganisira makiyi screws senge load-bearing protrusion screws uye posterior process screws.Mushure mekuderedzwa kuburikidza ne sinus tarsi yekupinda nzira, aya screws anogona kuiswa pasi pe cartilage kuti atsigire.
Pane makakatanwa akati wandei maererano nekushandiswa kwe intramedullary zvipikiri zvecalcaneal fractures:
1. Kukodzera kunobva pakuputsika kwakaoma: Inokakavadzana kana zvipembenene zviri nyore hazvidi kuti intramedullary misumari uye fractures yakaoma haina kukodzera kwavari.Kune maSanders emhando II/III akatyoka, nzira yekudzikisa uye screw fixation kuburikidza ne sinus tarsi yekupinda nzira yakura, uye kukosha kweiyo main intramedullary chipikiri kunogona kubvunzwa.Pakutyoka kwakaomarara, zvakanakira "L" yakaumbwa yakawedzera nzira inoramba isingachinjiki, sezvo ichipa kuratidzwa kwakakwana.
2. Kudikanwa kweiyo artificial medullary canal: Iyo calcaneus inongogara isina medullary canal.Kushandisa hombe intramedullary chipikiri kunogona kukonzera kukuvadzwa kwakanyanya kana kurasikirwa kwebhonzo.
3. Kuomerwa mukubvisa: Muzviitiko zvakawanda muChina, varwere vachiri kubviswa Hardware mushure mekuporeswa kwekutyoka.Kubatanidzwa kwembambo nekukura kwebhonzo uye kunyudzwa kwema lateral screws pasi pe cortical bone kunogona kutungamirira kune kuoma kwekubvisa, iyo inofungidzirwa inoshanda mukushandiswa kwekliniki.
