1.Ikhanda Elinamandla (DHS)
Ukuphuka kwenyonga phakathi kwama-tuberosities - intambo yomgogodla eqiniswe yi-DHS:
★DHS amandla worm izinzuzo eziyinhloko:
I-screw-on fixation yangaphakathi yethambo le-hip inomphumela onamandla, futhi ingasetshenziswa ngokuphumelelayo ezimweni lapho ithambo lisetshenziswa khona ngokushesha.
I-in-cylinder gliding mechanism igwemeke ukubhobozwa kwethiphu yamahhala ye-hip bone noma i-molar, amandla adonsela phansi aholela ngqo ethanjeni.
Ukumiswa kabusha kokuphuka kwedivayisi eslayidayo, ukonakala okuncane.
Ikhono elicindezelayo nelishelelayo eliphindwe kabili, nesenzo sokucindezela okumile.
★ Ubuthakathaka besitimela samandla e-DHS:
Ikhono elikhubazekile lokulwa nokujikeleza, ngemuva kwezicathulo eziboshiwe ezijwayelekile noma ukulungiswa kwe-polymer kwangaphandle.
I-periosteum ephakathi ilimele kakhulu, ukunwebeka kwezicubu, ukugqabuka kokunikelwa kwegazi, futhi uphenyo luthole ukuthi ithambo laligxilile ogebhezini, futhi ithambo lonakele kakhulu.
Ngesikhathi sokulungiswa, kuneqhubu elibi ngaphansi kokuvula, ukulimala kwe-blade kubi kakhulu, isikulufu sokulungisa ikhanda simahhadla, ububanzi bungaba ngu-15mm, futhi akunakwenzeka ukuvula izikhathi eziningi.
I-engeli igxilwe kumadigri angu-130 noma ama-degree angu-135, futhi i-engeli yangempela yesiguli iyalungiswa ngokufanele.
2. Igiya elinamandla (DCS)
Ukuphuka kwe-hip-fracture-DCS fixation:
I-DCS isamba se-95-degree incision steel plate-treated reflex fracture:
★Izinzuzo eziyinhloko ze-DCS Kinky Dragon:
Kungenzeka ukukhetha indawo efanele yokungena yokuphuka kwezimpande, kanye nendlela yokusebenza kwenqubo.
Amandla asetshenziswa ku-steel plate aseduze ne-engeli elungile, kanye nezidingo ze-biomechanical zomgogodla ofanayo.Ngaphansi komthwalo osindayo, amandla adonsela phansi asetshenziswa entanyeni yepuleti lensimbi, bese isakazwa kabusha kusikulufa ngasinye, ukucindezeleka kuyasatshalaliswa, futhi ukulungiswa kuhlala kuqinile.
Inani elincane le-DCS spiral fractures, ukuqina okukhulayo, ukulungiswa endaweni yokuphuka, kanye nezinga eliphansi lezehlakalo kamuva.
3.Iphinikhodi ye-hip bone ye-Proximal (PFN)
Ukuphuka kwe-hip phakathi kwe-tuberosities-PFN fixation:
★PFN izinzuzo ezilungisiwe:
Ububanzi bomzimba buncane kakhulu (ngokuvamile 9mm), futhi akunakwenzeka ukubufaka.(Ithiphu ye-Gamma enhle kakhulu——17mm)
Ukuphela okuseduze kwe-PFN kune-engeli yangaphandle ecishe ibe ngamadigri angu-6, i-engeli yangaphandle iyancipha, futhi awekho amandla angaphakathi aqinile lapho udonsa.
Ingxenye engenhla ingafakwa ethanjeni le-hip nge-spirals emibili, ukwanda kwe-anti-rotation spirals, amazinyo aphindwe kabili ngaphakathi kwethambo le-hip, kanye nekhono lokulwa nokukhathala.
I-keyhole ekude kanye nokhiye oyinhloko (ubude obude) buqhelelene kakhulu, futhi ukugxila kokucindezeleka kwethambo le-hip kungancishiswa.
★ PFN amaphutha alungisiwe:
Kunenkinga ethile ngokufaka okufanayo okuhambisanayo kwe-mother-of-pearl ohlangothini lwethambo le-hip, ikakhulukazi uma umfushane futhi umncane, ithambo le-hip lifushane kakhulu, futhi owesifazane osekhulile, udinga ukusebenzisa lokhu. ithambo le-hip.Intambo ye-helical engu-6.5mm), isikhundla se-leash silungiswa njalo ngesikhathi sokusetshenziswa okuphuthumayo, futhi phakathi nenqubo yokulungiswa kwangempela, ukunemba kokuqala kungase kulahleke.Amandla okugcina ngesikhathi esisodwa nawo ayinkinga enkulu.Ngaphezu kwalokho, kunengozi yokugoqa amathambo, okuhambisana nokuwohloka kwamathambo kalula ngenxa yezimpande ezimbili ze- spiral dynamic.
Ngenxa ye-PFN, i-arc inkulu, futhi yinde kakhulu.ukuphuka.Ngenxa yalolu shintsho, indawo yenkaba yangaphakathi ilungile, futhi i-cortex eduze nentambo yangaphandle yenkaba yangaphakathi ngokungangabazeki ikhona.
Inani elikhulu lemisebe, izindleko eziphezulu zamathuluzi okuhlinza, nezimfuno eziphezulu zekhono lokuhlinza.
