Cancellous Screw: Mhedziso Yemashandisirwo, Zviratidzo, uye Maitiro
Nhanganyaya
Cancellous screws imhando ye orthopedic screw inoshandiswa kugadzirisa zvimedu zvemapfupa kana magraft mukurapa kwekutyoka, kusabatanidzwa, uye kumwe kukuvara kwebhonzo. Aya ma screws anoshandiswa zvakanyanya mukuvhiya kwemapfupa nekuda kweiyo biocompatibility, nyore kuisa, uye yakanakisa mechaniki zvivakwa. Muchikamu chino, tichakurukura zviratidzo, maitiro, uye mhedzisiro yekushandisa cancellous screws mukuvhiya kwemapfupa.
Anatomy uye Mechanical Properties yeCancellous Screw
Cancellous screws inogadzirwa netitanium kana simbi isina tsvina uye ine shinda ine shinda uye muromo wakatepwa. Tambo dziri pashaft dzinopa kutenga kwakanaka mubhonzo rekudzima uye kudzivirira kudhonza-kunze, ukuwo tapered tipi inogonesa kupinza nyore pasina kukuvadza matishu akatenderedza. Iyo screws inouya muhukuru hwakasiyana uye kureba kuti igare akasiyana masaizi emapfupa uye mapatani ekutyoka. Iyo mechanical zvimiro zve cancellous screws zvinoenderana nechinhu, dhayamita, kureba, uye shinda dhizaini. Kushandiswa kwedhayamita yakakura uye yakareba screws inowedzera simba rekubata uye kugadzikana, nepo kushandiswa kwediki dhayamita uye mapfupi screws kunoderedza njodzi yekuwedzeredza uye screw migration.
Zviratidzo zveCancellous Screw Fixation
Cancellous screws inoratidzwa kune dzakasiyana siyana dzemapfupa emapfupa, kusanganisira:
Kutsemuka kwemapfupa akareba, akadai sefemur, tibia, uye humerus
Kutyoka kwemapfupa madiki, seruoko, chiziso, uye tsoka
Zvisiri-mibatanidzwa uye kunonoka mibatanidzwa yemafractures
Osteotomies, yakadai sekugadzirisa mapfupa ekucheka kwehurema kana kusarurama
Arthrodesis, yakadai sekusanganiswa kwechidzitiro, wrist, kana musana
Bone graft fixation, senge mune spinal fusion kana bone defect kuvakazve
Matekiniki eCancellous Screw Fixation
Iyo tekinoroji yekukanzura screw fixation inotsamira pane chaiyo chiratidzo uye fracture pateni. Iyo general misimboti yekuisa screw inosanganisira:
Kumira kwakakodzera kwemurwere uye kuzivikanwa kwenzvimbo yekuputsika
Kugadzirwa kwegomba rekutyaira uchishandisa chibooreso kana tap
Kuyera kureba kwescrew uye dhayamita
Kuiswa kwescrew uchishandisa screwdriver kana chibooreso chemagetsi
Kuongororwa kweiyo screw chinzvimbo uye kudzika uchishandisa imaging modalities, senge fluoroscopy kana X-ray
Zvinhu zvakakosha zvinokanganisa budiriro yekukanzura screw fixation zvinosanganisira kurongeka kwakaringana kwezvimedu zvekutyoka, kudzikisira kwakaringana kwekutyoka, kuiswa screw kwakakodzera uye kureba, uye kudzvanya kwakakodzera kwescrew. Matambudziko ekukanzura screw fixation anosanganisira screw kusunungura, screw breakage, screw migration, non-union, malunion, hutachiona, uye kukuvara kwetsinga kana mudziyo.
Migumisiro yeCancellous Screw Fixation
Mhedzisiro yekukanzura screw fixation zvinoenderana nechainoratidza uye murwere zvinhu, sezera, comorbidities, uye chimiro chekuputa. Kazhinji, cancellous screw fixation inopa kugadzikana kwakanakisa uye kudzvanywa kwezvimedu zvekutyoka, izvo zvinotungamira nekukurumidza kupora kwemapfupa uye kudzoreredza kweyakajairika basa. Huwandu hwebudiriro yekukanzura screw fixation inotangira pa80% kusvika 95%, zvichienderana nechiratidzo uye pateni yekutyoka. Matambudziko ekukanzura screw fixation anogona kutungamira kune hurombo mhedzisiro, sekunonoka kupora, kusiri mubatanidzwa, uye kurwadziwa kusingaperi.
Mhedziso
Cancellous screws chishandiso chinogoneka uye chinoshanda mukuvhiya kwemapfupa ekugadzirisa mapfupa ekutyoka, magrafts, uye fusion. Iko kushandiswa kwakaringana kwekanzura screws kunoda kunyatsonzwisisa kweanatomy, zviratidzo, matekiniki, uye mhedzisiro yemaitiro. Kusarudzwa kwehukuru hwakakodzera screw, kureba, uye nzira yekuisa inofanirwa kuenderana neiyo chaiyo yekutyoka pateni uye nemurwere zvinhu. Iko kushandiswa kwekanzura screws kunogona kutungamira kune zvakanakisa mhedzisiro uye nekukurumidza kupora, asi kunyatsotarisisa uye manejimendi ematambudziko akakosha kune yakanyanya mhedzisiro.
