Cancellous Screw: Nkatsakanyo wa Matirhiselo, Swikombiso na Tithekiniki
Manghenelo
Cancellous screws i muxaka wa orthopaedic screw leyi tirhisiwaka ku khoma swiphemu swa marhambu kumbe ti grafts eka vutshunguri bya ku tshoveka, non-unions, na ku vaviseka kun’wana ka marhambu. Ti screws leti titirhisiwa ngopfu eka vuhandzuri bya marhambu hikokwalaho ka biocompatibility ya tona, ku olova ku nghenisiwa, xikan’we na swivumbeko swa kahle swa michini. Eka xihloko lexi, hi ta bula hi swikombiso, tindlela ni vuyelo bya ku tirhisa swikwirikiri leswi nga ni cancellous eka vuhandzuri bya marhambu.
Anatomy na Swihlawulekisi swa Michini swa Cancellous Screw
Ti screws ta cancellous ti endliwe hi titanium kumbe stainless steel naswona tina threaded shaft na tapered tip. Ti threads eka shaft tinyika ku xava lokunene eka cancellous bone naswona ti sivela ku koka, kasi tapered tip yi olovisa ku nghenisiwa hiku olova handle ko onha ti tissues leti rhendzeleke. Ti screws tina vukulu byohambana hambana na ku leha kuva ti amukela vukulu byohambana hambana bya marhambu xikan’we na swivumbeko swo tshoveka. Swivumbeko swa michini swa swikwirikiri swa cancellous swi titshege hi swilo leswi endliweke, dyayimeta, ku leha ni ndlela leyi thyaka ri endliweke ha yona. Ku tirhisiwa ka diameter leyikulu na swikwirikiri swo leha swi engetela matimba yo khoma na ku tiya, kasi ku tirhisiwa ka diameter leyintsongo na swikwirikiri swo koma swi hunguta khombo ra ku bora ngopfu na ku rhurha ka swikwirikiri.
Swikombiso swa Cancellous Screw Fixation
Swikwirikiri swa cancellous swi kombisiwa eka swiyimo swo hambana swa marhambu, ku katsa na:
Ku tshoveka ka marhambu yo leha, yo tanihi femur, tibia na humerus
Ku tshoveka ka marhambu lamatsongo, yo tanihi voko, xirhendze ni nenge
Ku nga ri tiyuniyoni na ku hlwela ka tiyuniyoni ta ku tshoveka
Ku tsemiwa ka marhambu, ku fana ni ku tsemiwa ka marhambu loku lulamisaka leswaku ma nga onhaki kumbe ma nga ringani
Arthrodesis, yo tanihi ku hlanganisiwa ka xirhendze, voko kumbe nkolo
Ku khomiwa ka marhambu ya graft, kufana na le ka spinal fusion kumbe bone defect reconstruction
Tithekiniki ta ku Tiyisisa Swikwirikiri hi Cancellous
Thekiniki ya cancellous screw fixation yiya hi xikombiso xokarhi na xivumbeko xa fracture. Misinya ya milawu yo angarhela ya ku nghenisiwa ka swikwirikiri yi katsa:
Ku vekiwa loku faneleke ka muvabyi na ku tiviwa ka ndhawu leyi tshovekeke
Ku endliwa ka pilot hole hiku tirhisa drill bit kumbe pompi
Ku pimiwa ka ku leha ka xikurufu na dyayimeta
Ku nghenisiwa ka xikurufu hiku tirhisa screwdriver kumbe power drill
Ku tiyisisiwa ka ndzhawu ya screw na vuenti hiku tirhisa tindlela ta swifaniso, kufana na fluoroscopy kumbe X-ray
Swilo swa nkoka leswi khumbhaka ku humelela ka cancellous screw fixation swikatsa ku ringanisiwa kahle ka swiphemu swa fracture, kuhungutiwa loku ringaneleke ka fracture, ku vekiwa loku faneleke ka screw na ku leha, na ku tsindziyela kahle ka screw. Swiphiqo swa ku khomiwa ka swikwirikiri swa cancellous swi katsa ku ntshunxeka ka swikwirikiri, ku tshoveka ka swikwirikiri, ku rhurha ka swikwirikiri, ku nga hlanganisiwi, ku hlangana loku nga riki kahle, ku tluleriwa, na ku vaviseka ka misiha kumbe misiha.
Vuyelo bya ku Khomisiwa ka Swikwirikiri swa Cancellous
Vuyelo bya cancellous screw fixation byi titshege hi xikombiso xo karhi na swilo swa muvabyi, swo tanihi malembe, comorbidities, na xiyimo xa ku dzaha fole. Hiku angarhela, cancellous screw fixation yinyika kutshamiseka lokunene xikan’we naku tshikileriwa ka swiphemu swa fracture, leswi endlaka leswaku marhambu ya hola hiku hatlisa xikan’we naku vuyiseriwa ka ntirho lowu tolovelekeke. Nhlayo ya ku humelela ka cancellous screw fixation yisuka eka 80% kuya eka 95%, kuya hi xikombiso na xivumbeko xa ku tshoveka. Swiphiqo swa ku khomiwa hi cancellous screw swi nga endla leswaku ku va ni vuyelo byo biha, byo tanihi ku hlwela ku hola, ku nga hlanganisiwi ni ku vava loku nga heriki.
Mahetelelo
Swikwirikiri swa cancellous i xitirho lexi tirhisiwaka hi tindlela to hambana-hambana ni lexi tirhaka eka vuhandzuri bya marhambu xo khoma ku tshoveka ka marhambu, ku nghenisiwa ka marhambu ni ku hlanganisiwa ka marhambu. Ku tirhisiwa lokunene ka swikwirikiri leswi nga ni cancellous swi lava ku twisisa loku heleleke ka anatomy, swikombiso, tindlela ni vuyelo bya endlelo leri. Ku hlawuriwa ka sayizi ya screw leyi faneleke, ku leha, na thekiniki yo nghenisa swifanele ku lulamisiwa kuya hi xivumbeko xokarhi xa ku tshoveka na swilo swa muvabyi. Ku tirhisiwa ka ti cancellous screws swinga endla leswaku kuva na mbuyelo wa kahle swinene xikan’we naku hola hiku hatlisa, kambe ku vekiwa tihlo hi vukheta naku lawula swiphiqo swina nkoka eka mbuyelo lowunene.
Swivutiso leswi talaka ku vutisiwa
Xana xikurufu xa cancellous i yini? Cancellous screw i xikurufu xa marhambu lexi tirhisiwaka ku khoma swiphemu swa marhambu kumbe swiphemu leswi hlanganisiweke eka vutshunguri bya ku tshoveka, ku nga hlanganisiwi na ku vaviseka kun’wana ka marhambu.
Hi swihi swikombiso swa cancellous screw fixation? Ti screws ta cancellous ti kombisiwa eka swiyimo swohambana hambana swa orthopaedic, kukatsa na ku tshoveka, non-unions, osteotomies, arthrodesis, na bone graft fixation.
Hi swihi swilo swa nkoka leswi khumbaka ku humelela ka cancellous screw fixation? Swilo swa nkoka leswi khumbhaka ku humelela ka cancellous screw fixation swikatsa ku ringanisiwa kahle ka swiphemu swa fracture, kuhungutiwa loku ringaneleke ka fracture, ku vekiwa loku faneleke ka screw na ku leha, na ku tsindziyela kahle ka screw.
Hi swihi swiphiqo swa ku khomiwa ka swikwirikiri hi cancellous? Swiphiqo swa ku khomiwa ka swikwirikiri hi cancellous swi katsa ku ntshunxeka ka swikwirikiri, ku tshoveka ka swikwirikiri, ku rhurha ka swikwirikiri, ku nga hlanganisiwi, malunion, ku tluleriwa, na ku vaviseka ka misiha kumbe misiha.
Hi byihi vuyelo bya ku khomiwa ka swikwirikiri hi cancellous? Vuyelo bya cancellous screw fixation byi titshege hi xikombiso xokarhi na swilo swa muvabyi, kambe hiku angarhela, cancellous screw fixation yinyika kutshamiseka lokunene xikan’we naku tshikileriwa ka swiphemu swa fracture, leswi yisaka eka ku hola ka marhambu hiku hatlisa xikan’we naku vuyiseriwa ka ntirho lowu tolovelekeke.
