1.Lehata le Matla (DHS)
Ho robeha ha letheka pakeng tsa li-tuberosities - DHS e matlafalitse lesapo la mokokotlo:
★DHS power worm melemo e ka sehloohong:
The screw-on fixation ea ka hare ea lesapo la hip e na le phello e matla, 'me e ka sebelisoa ka katleho maemong ao lesapo le sebelisoang hang-hang.
In-cylinder gliding mechanism e ka qojoa ho phunyeha ha lesapo la noka kapa molar, matla a khoheli a fosahetseng a lebisa lesapong.
Sesebediswa se thellang se bolokang fracture repositioning, tshenyo e nyane.
Bokhoni ba ho hatella le ho thella habeli, bo nang le ketso e sebetsang ea khatello e tsitsitseng.
★ bofokoli ba terene ea matla ea DHS:
Bokhoni ba ho thibela ho potoloha, ka mor'a lieta tse tloaelehileng tse koetsoeng kapa ho lokisa polymer kantle.
Periosteum e bohareng e senyehile haholo, ho atolosoa ha lisele, ho phatloha ha phano ea mali, 'me lipatlisiso li fumane hore lesapo le ne le tsitsitse lehata,' me lesapo le senyehile haholo.
Nakong ea ho lokisa, ho na le leqhubu le thata ka tlas'a ho buloa, tšenyo ea lehare e matla, sekoti sa ho lokisa hlooho se mahoashe, bophara bo ka bang 15mm, 'me ha ho khonehe ho bula makhetlo a mangata.
Lehlakore le behiloe ho likhato tse 130 kapa likhato tse 135, 'me lehlakore la sebele la mokuli le lokisoa ka tsela e nepahetseng.
2. Dynamic gear (DCS)
Ho robeha ha letheka—ho lokisa DCS:
DCS e akaretsa 95-degree steel incision reflex fracture:
★DCS Kinky Dragon Melemo e ka Sehloohong:
Hoa khoneha ho khetha sebaka se nepahetseng sa ho kena bakeng sa ho robeha ha metso, le mokhoa oa ts'ebetso ea ts'ebetso.
Matla a sebelisoang ho tšepe ea tšepe e haufi le lehlakoreng le nepahetseng, le litlhoko tsa biomechanical tsa mokokotlo o ts'oanang.Tlas'a mojaro o boima, matla a khoheli a sebelisoa molala oa poleiti ea tšepe, ebe e aroloa hape ho sekoti se seng le se seng, khatello ea kelello e ajoa, 'me ho lokisoa ho lula ho le thata.
Palo e nyane ea DCS spiral fractures, ho eketseha ho tiea, ho lokisa sebakeng sa fracture, le sekhahla se tlase sa liketsahalo ka mor'a moo.
3.Proximal hip bone pin (PFN)
Ho robeha ha letheka pakeng tsa li-tuberosities-PFN fixation:
★PFN melemo e tsitsitseng:
Bophara ba 'mele bo nyane haholo (ka kakaretso 9mm),' me ho ke ke ha khoneha ho e kenya.(Keletso e ntle e mahoashe ea Gamma——17mm)
Qetello e haufi ea PFN e na le angle e ka ntle ea likhato tse ka bang 6, lehlakoreng le ka ntle le fokotsehile, 'me ha ho na matla a matla a ka hare ha a hula.
Karolo e ka holimo e ka kenngoa ka har'a lesapo la noka ka li-spirals tse peli, ho eketseha ha li-anti-rotation spirals, meno a mabeli ka har'a lesapo la noka, le ho eketsa matla a ho thibela mokhathala.
Senotlolo sa ho qetela le senotlolo se seholo (bolelele ba nako e telele) se arohane haholo, 'me khatello ea khatello ea lesapo la letheka e ka fokotseha.
★ PFN liphoso tse tsitsitseng:
Ho na le bothata bo itseng ka ho kenngoa ka mokhoa o nepahetseng ka ho tšoana ha 'mè oa perela tse peli ka lehlakoreng la lesapo la noka, haholo-holo haeba u le khutšoanyane ebile u le monyane, lesapo la letheka le lekhutšoanyane haholo, le mofumahali ea hōlileng, o hloka ho sebelisa sena. lesapo la letheka.6.5mm helical thread), boemo ba leash bo lula bo fetoloa nakong ea tšebeliso e potlakileng, 'me nakong ea ts'ebetso ea sebele ea ho lokisa, ho nepahala ha pele ho ka' na ha lahleha.Bokhoni ba ho boloka ka nako e le 'ngoe le bona ke bothata bo boholo.Ho phaella moo, ho na le kotsi ea ho robeha ha masapo, e tsamaeang le ho senyeha ha masapo habonolo ka lebaka la metso e 'meli ea spiral e matla.
Ka lebaka la PFN, arc e kholo, 'me e telele haholo.robeha.Ka lebaka la phetoho ena, boemo ba mokokotlo oa ka hare bo nepahetse, 'me ha ho pelaelo hore cortex e haufi le lesela le ka ntle la mokokotlo oa ka hare.
Chelete e ngata ea mahlaseli, theko e phahameng ea lisebelisoa tsa ho buoa, le litlhoko tse phahameng tsa tsebo ea ho buoa.
