1. Dynamic Skull (DHS)
Hip fracture ntawm tuberosities - DHS txhawb nqa qaum qaum:
★ DHS lub zog worm lub ntsiab zoo:
Cov ntsia hlau-ntawm sab hauv kho ntawm pob txha pob txha muaj zog, thiab tuaj yeem siv tau zoo nyob rau hauv cov xwm txheej uas cov pob txha siv tam sim ntawd.
Nyob rau hauv-lub tog raj kheej gliding mechanism zam tsis pub dawb tip perforation ntawm lub duav pob txha los yog molar, tsis zoo lub ntiajteb txawj nqus ncaj qha mus rau cov pob txha.
Lub zog zawv zawg ntaus ntawv tuav cov pob txha repositioning, kev puas tsuaj tsawg dua.
Compressive thiab zawv zawg ob lub peev xwm, nrog kev ua haujlwm zoo li qub.
★ DHS fais fab tsheb ciav hlau qhov tsis muaj zog:
Impaired anti-rotation muaj peev xwm, tom qab ib txwm clenched nkawm khau los yog polymer sab nrauv fixation.
Lub nruab nrab periosteum raug puas tsuaj loj, qhov nthuav dav ntawm cov ntaub so ntswg, rupture ntawm cov ntshav pub dawb, thiab kev tshawb nrhiav pom tias cov pob txha raug kho nyob rau hauv pob txha taub hau, thiab cov pob txha raug mob hnyav.
Thaum lub sij hawm ntawm fixation, muaj ib tug ntxhib bulge nyob rau hauv lub qhib, cov hniav puas loj heev, lub taub hau fixation ntsia hlau yog ntxhib, lub cheeb yog hais txog 15 hli, thiab nws yog tsis yooj yim sua kom qhib ntau zaus.
Lub kaum sab xis yog kho ntawm 130 degrees lossis 135 degrees, thiab tus neeg mob lub kaum ntse ntse raug kho raws li.
2. Dynamic iav (DCS)
Pob txha pob txha pob txha - DCS fixation:
DCS sum 95-degree incision steel phaj-kho reflex puas:
★DCS Kinky Dragon Qhov Zoo Tshaj Plaws:
Nws muaj peev xwm xaiv qhov tseeb nkag nkag rau hauv paus tawg, thiab cov txheej txheem kev ua haujlwm.
Lub zog siv rau lub phaj steel yog nyob ze rau ntawm lub kaum sab xis, thiab cov kev xav tau ntawm biomechanical ntawm cov nqaj qaum.Nyob rau hauv qhov hnyav hnyav, lub ntiajteb txawj nqus yog siv rau lub caj dab ntawm lub phaj steel, thiab tom qab ntawd rov muab faib rau txhua tus ntsia hlau, qhov kev ntxhov siab raug faib, thiab kev kho yog ib txwm nruj.
Ib tug me me ntawm DCS kauv pob txha, nce solidity, fixation ntawm qhov chaw tawg, thiab qhov tshwm sim tsawg tom qab.
3.Proximal hip pob txha tus pin (PFN)
Lub duav pob txha ntawm tuberosities-PFN fixation:
★ PFN qhov zoo ruaj khov:
Txoj kab uas hla ntawm lub cev yog me me (feem ntau 9 hli), thiab nws tsis tuaj yeem ntxig nws.(Zoo heev Gamma ntxhib taub - 17mm)
Qhov kawg ntawm PFN muaj lub kaum sab nraud ntawm kwv yees li 6 degrees, lub kaum sab nraud raug txo, thiab tsis muaj zog sab hauv thaum rub.
Sab saum toj kawg nkaus tuaj yeem muab tso rau hauv cov pob txha pob txha nrog ob lub kauv, muaj zog tiv thaiv kev sib hloov spirals, ob chav hniav hauv cov pob txha, thiab muaj peev xwm tiv thaiv kev qaug zog.
Qhov deb-kawg keyhole thiab lub ntsiab tseem ceeb (ntev-kawg ntev) nyob deb sib nrug, thiab qhov kev ntxhov siab ntawm cov pob txha pob txha tuaj yeem txo qis.
★ PFN tsau flaws:
Muaj qee qhov teeb meem nrog qhov tseeb qhov sib npaug ntawm ob niam txiv-ntawm-pearl ntawm sab ntawm lub duav pob txha, tshwj xeeb tshaj yog tias koj luv thiab me, cov pob txha ntawm lub duav luv heev, thiab cov poj niam laus, koj yuav tsum siv qhov no. luj hip.6.5mm helical xov), txoj hauj lwm ntawm txoj hlua khi yog hloov kho tas li thaum lub sijhawm siv ceev, thiab thaum lub sijhawm hloov kho tiag tiag, qhov tseeb thawj zaug yuav poob.Simultaneous tuav peev xwm kuj yog ib qho teeb meem loj.Tsis tas li ntawd, muaj kev pheej hmoo ntawm pob txha crumpling, uas yog nrog los ntawm cov pob txha yooj yim degeneration vim yog ob lub hauv paus ntawm cov dynamic kauv.
Vim yog PFN, lub arc loj, thiab nws ntev dhau lawm.tawg.Vim tias qhov kev hloov pauv no, txoj haujlwm ntawm txoj hlab ntaws sab hauv yog qhov tseeb, thiab lub cortex nyob ze rau sab nraud ntawm txoj hlab ntaws sab hauv ntawm txoj hlab ntaws yog undoubtedly nyob.
Cov hluav taws xob ntau, tus nqi siab ntawm cov cuab yeej phais, thiab kev xav tau siab ntawm kev phais mob.
