Cancellous screws ke mofuta oa sekukuru sa masapo se sebelisetsoang ho lokisa likhechana tsa masapo kapa li-grafts ho phekola ho robeha, ho se kopane, le likotsi tse ling tsa masapo. Li-screws tsena li sebelisoa haholo ho buoang masapo ka lebaka la biocompatibility ea tsona, ho kenngoa habonolo ha tsona, le thepa e ntle ea mochini. Sengoliloeng sena, re tla tšohla matšoao, mekhoa le liphetho tsa ho sebelisa li-screw tsa ho etsa opereishene ea masapo.
Anatomy le Mechanical Properties of Cancellous Screw
Li-Screwous screws li entsoe ka titanium kapa tšepe e sa hloekang 'me li na le shaft e khoele le ntlha e tepeletseng. Likhoele tse holim'a shaft li fana ka theko e ntle haholo lesapong le hlakolang 'me li thibela ho tsoa, ha ntlha e tapered e thusa ho kenngoa habonolo ntle le ho senya lisele tse potolohileng. Li-screw li tla ka boholo le bolelele bo fapaneng ho amohela boholo bo fapaneng ba masapo le mekhoa ea ho robeha. Thepa ea mochini ea li-screws e itšetlehile ka thepa, bophara, bolelele le moralo oa khoele. Tšebeliso ea li-screws tse kholoanyane le li-screws tse telele li eketsa matla a ho tšoara le botsitso, ha tšebeliso ea bophara bo nyane le li-screw tse khutšoanyane li fokotsa kotsi ea ho phunya le ho falla ha screw.
Lipontšo tsa ho Lokisoa ha Cancellous Screw
Li-screws tsa Cancellous li bontšoa bakeng sa maemo a fapaneng a masapo, ho kenyelletsa:
Ho robeha ha masapo a malelele, joalo ka femur, tibia le humer
Ho robeha ha masapo a manyenyane, joalo ka letsoho, leqaqailana le leoto
Bao e seng mekhatlo le mekhatlo e liehang ea ho robeha
Li-osteotomies, tse kang ho khaola masapo bakeng sa ho holofala kapa ho se sebetse hantle
Arthrodesis, joalo ka ho kopanngoa ha leqaqailaneng, letsoho kapa mokokotlo
Ho lokisa lesapo, joalo ka ho kopanngoa ha lesapo la mokokotlo kapa ho aha bofokoli ba masapo
Mekhoa ea ho Lokisoa ka Cancellous Screw
Mokhoa oa ho lokisa screwous screw o ipapisitse le sesupo se ikhethileng le sebopeho sa fracture. Melao-motheo e akaretsang ea ho kenya screw e kenyelletsa:
Boemo bo nepahetseng ba mokuli le ho tsebahatsa sebaka sa fracture
Ho etsa lesoba la sefofane ka ho sebedisa boro kapa pompo
Tekanyo ea bolelele le bophara ba screw
Ho kenya sekurufu ka ho sebedisa screwdriver kapa boro ya matla
Netefatso ea boemo ba screw le botebo ka ho sebelisa mekhoa ea ho nka litšoantšo, joalo ka fluoroscopy kapa X-ray
Lintlha tsa bohlokoa tse amang katleho ea ho lokisa sekoti sa ho hlakola li kenyelletsa ho tsamaisana hantle ha likhechana tse robehileng, phokotso e lekaneng ea ho robeha, sebaka se loketseng sa screw le bolelele, le tsitsipano e nepahetseng ea screw. Mathata a ho hlakoloa ha screw fixation a kenyelletsa ho lokoloha ha screw, ho robeha ha screw, ho falla ha screw, ho se kopane, malunion, tšoaetso, le kotsi ea methapo kapa sekepe.
Liphetho tsa Cancellous Screw Fixation
Liphetho tsa ho lokisa sekoti sa ho hlakoloa li ipapisitse le sesupo se ikhethileng le lintlha tsa mokuli, joalo ka lilemo, mafu a amanang le ho tsuba, le boemo ba ho tsuba. Ka kakaretso, ho lokisa screwous screw ho fana ka botsitso bo babatsehang le khatello ea likhechana tsa fracture, e leng se lebisang ho pholiso ea masapo le ho tsosolosoa ha mosebetsi o tloaelehileng. Sekhahla sa katleho ea ho lokisa sekoti se tlohang ho 80% ho isa ho 95%, ho latela pontšo le mokhoa oa ho robeha. Mathata a ho hlakoloa ha screw fixation a ka lebisa liphellong tse fokolang, tse kang ho lieha ho fola, ho se kopane, le bohloko bo sa foleng.
Qetello
Li-Screwous screws ke sesebelisoa se feto-fetohang le se sebetsang ho opereishene ea masapo bakeng sa ho lokisa ho robeha ha masapo, li-grafts le fusion. Tšebeliso e nepahetseng ea li-screws tsa ho hlakola e hloka kutloisiso e feletseng ea anatomy, matšoao, mekhoa le liphello tsa ts'ebetso. Khetho ea boholo bo nepahetseng ba sekoti, bolelele, le mokhoa oa ho kenya o lokela ho lumellana le mokhoa o khethehileng oa ho robeha le lintlha tsa mokuli. Tšebeliso ea li-screws tse hlakolang li ka lebisa liphellong tse babatsehang le pholiso e potlakileng, empa ho lekoa ka hloko le ho laola mathata ho bohlokoa bakeng sa liphello tse nepahetseng.
