1.Dynamic Skall (DHS)
Ukuqhekeka kwe-Hip phakathi kwe-tuberosities-i-DHS yomeleza intambo yomqolo:
★DHS amandla worm eziphambili inzuzo:
I-screw-in fixation yangaphakathi ye-hip bone inefuthe elinamandla, kwaye ingasetyenziselwa ngokufanelekileyo kwiimeko apho ithambo lisetyenziswa ngokukhawuleza.
I-in-cylinder gliding mechanism inokuphepheka i-tip yamahhala ye-hip bone okanye i-molar, ubunzima obubi bukhokelela ngqo kwithambo.
Ugcino lwesixhobo sokutyibiliza samandla, ukuncipha komonakalo.
Ukunyanzeliswa kunye nokutyibilika okuphindwe kabini, kunye nesenzo soxinzelelo olusebenzayo.
★ Ubuthathaka bukaloliwe wamandla we-DHS:
Ukungaphumeleli ukukwazi ukujikeleza, emva kwezicathulo eziqhelekileyo ezibhinqiweyo okanye ukulungiswa kwe-polymer yangaphandle.
I-periosteum ephakathi yonakaliswe kakhulu, i-detachment ebanzi ye-tissue, i-rupture ye-blood donation, kunye nophando lufumene ukuba ithambo lilungiswe kwi-skull, kwaye ithambo lonakaliswe kakhulu.
Ngexesha lokulungiswa, kukho i-bulge enqabileyo phantsi kokuvula, umonakalo we-blade unzima, i-screw yokulungiswa kwentloko i-coarse, ububanzi bumalunga ne-15mm, kwaye akunakwenzeka ukuvula amaxesha amaninzi.
I-angle igxininiswe kwii-degrees ze-130 okanye i-135 degrees, kwaye i-angle yoqobo yesigulane ilungiswa ngokufanelekileyo.
2. Isixhobo esinamandla (i-DCS)
Ukwaphuka kwenyonga-Ukulungiswa kweDCS:
I-DCS sum 95-degree incision steel plate-treated reflex fracture:
★I-DCS Kinky Dragon Eyona nto iluncedo:
Kuyenzeka ukuba ukhethe indawo yokungena echanekileyo yokuqhekeka kweengcambu, kunye nendlela yokusebenza kwenkqubo.
Amandla asetyenziswe kwi-plate yensimbi isondele kwi-angle echanekileyo, kunye neemfuno ze-biomechanical zomgudu ohambelanayo.Ngaphantsi komthwalo onzima, ubunzima busetyenziswe entanyeni yentsimbi yensimbi, kwaye emva koko isasazwe kwi-screw nganye, uxinzelelo lusasazwa, kwaye ukulungiswa kuhlala lukhuni.
Inani elincinci le-DCS spiral fractures, ukunyuka kokuqina, ukulungiswa kwindawo yokuphuka, kunye nezinga eliphantsi lezehlo emva koko.
3.Iphini ye-hip bone ye-Proximal (PFN)
Ukuqhekeka kwe-Hip phakathi kwe-tuberosities-ukulungiswa kwePFN:
★PFN izibonelelo ezizinzileyo:
Ububanzi bomzimba buncinci kakhulu (ngokuqhelekileyo i-9mm), kwaye akunakwenzeka ukuyifaka.(Incam egqwesileyo yeGamma——17mm)
Isiphelo esisondeleyo se-PFN sine-angle yangaphandle malunga ne-6 degrees, i-angle yangaphandle iyancitshiswa, kwaye akukho mandla angaphakathi anamandla xa udonsa.
Isiphelo esiphezulu sinokufakwa kwithambo le-hip kunye ne-spirals ezimbini, ukunyuka kwe-anti-rotation spirals, amazinyo amabini ngaphakathi kwethambo le-hip, kunye nokwandisa amandla okulwa nokudinwa.
Isitshixo esisekude kunye nesitshixo esiphambili (ubude obude) bukude kakhulu, kwaye uxinzelelo lwexinzelelo lwethambo le-hip lungancitshiswa.
★ PFN iziphene ezilungisiweyo:
Kukho ingxaki ethile kunye nokufakwa okuchanekileyo okuhambelanayo kwe-mother-of-pearl ecaleni kwethambo le-hip, ngakumbi ukuba ufutshane kwaye uncinci, ithambo le-hip lifutshane kakhulu, kunye nenkosikazi endala, kufuneka usebenzise oku. ithambo lesinqe.I-6.5mm intambo ye-helical), isikhundla se-leash sihlala sihlengahlengiswa ngexesha lokusetyenziswa ngokukhawuleza, kwaye ngexesha lenkqubo yokulungiswa kwangempela, ukuchaneka kokuqala kunokulahleka.Ukukwazi ukugcina ngaxeshanye kuyingxaki enkulu.Ukongezelela, kukho umngcipheko wokuqhekeka kwamathambo, okuhamba kunye nokuchithwa kwamathambo ngokulula ngenxa yeengcambu ezimbini ze-spiral dynamic.
Ngenxa ye-PFN, i-arc inkulu, kwaye inde kakhulu.ukwaphuka.Ngenxa yolu tshintsho, indawo yentambo yangaphakathi ichanekile, kwaye i-cortex kufuphi nentambo yangaphandle yentambo yangaphakathi ngokungathandabuzekiyo ikhona.
Isixa esikhulu semitha, ixabiso eliphezulu lezixhobo zotyando, kunye neemfuno eziphezulu kwisakhono sotyando.
