Chii chinonzi Chidimbu chikuru chebhonzo ?
Chidimbu chikuru chebhonzo inoreva boka rekugadzirisa mapfupa rinoshandiswa pakuvhiyiwa kwemapfupa kurapa kuputsika kwemapfupa akareba, akadai sefemur (chidya), tibia (shin bone), uye humerus (bhonzo repamusoro reruoko).
Aya ma implants akagadzirirwa kudzikamisa kuputsika nekuvhara gap uye kubvumira bhonzo kupora munzvimbo chaiyo. Chidimbu chikuru chebhonzo maimplants anowanzo sanganisira simbi ma plates uye screws anozoiswa panzvimbo yebhonzo kuitira kuti mabhonzo arambe aripo.
Ma plates nema screws akakura uye akasimba kudarika anoshandiswa mu Chidimbu chidiki chebhonzo ma implants, sezvo achida kutsigira huremu hwakawanda uye kushingirira masimba makuru. Chidimbu chikuru chebhonzo maimplants anowanzo shandiswa mukutsemuka kwakanyanya kunoda kudzikamisa zvakanyanya.
Zvishandiso zve Locking plate ?
Locking plates anowanzo gadzirwa nezvinhu zvinopindirana nezvinhu zvakaita setitanium, titanium alloy, kana simbi isina tsvina. Zvishandiso izvi zvine simba rakanakisa, kuomarara, uye kusagadzikana kwekuora, zvichiita kuti zvive zvakanaka kuti zvishandiswe mu Ma-implant emabhonzo . Mukuwedzera, ivo vane inert uye havaiti pamwe nemuviri wenyama, kuderedza dambudziko rekuramba kana kuzvimba. Mamwe Locking plates anogona zvakare akaputirwa nezvinhu zvakaita sehydroxyapatite kana mamwe machira kuti avandudze kubatana kwawo nenyama yebhonzo.
Ndeipi ndiro iri nani titanium kana simbi isina tsvina?
Zvose mahwendefa etitanium uye simbi isina tsvina inowanzoshandiswa mukuvhiya kwemapfupa, kusanganisira ye Locking plates . Sarudzo pakati pezvinhu zviviri izvi zvinoenderana nezvinhu zvakati wandei, kusanganisira rudzi rwekuvhiyiwa, nhoroondo yekurapa yemurwere uye zvaanoda, uye ruzivo rwechiremba anovhiya uye zvaanoda.
Titanium chinhu chakareruka uye chakasimba icho chinopindirana uye chinoshingirira mukuora, zvichiita kuti ive sarudzo yakanakisa yekudyara kudyara. Titanium mahwendefa haana kuoma kupfuura mahwendefa esimbi asina tsvina, ayo anogona kubatsira kuderedza kushushikana kwepfupa uye kukurudzira kuporesa. Pamusoro pezvo, mahwendefa etitanium ane radiolucent, zvinoreva kuti haapindire nemiedzo yekufungidzira senge X-ray kana MRI.
Simbi isina tsvina, kune rumwe rutivi, chinhu chakasimba uye chakaomarara icho zvakare chinopindirana uye chinoshingirira mukuora. Yakashandiswa mu Ma-implant emabhonzo kwemakumi emakore uye chinhu chakaedzwa-uye-chechokwadi. Stainless simbi mahwendefa anodhura zvishoma pane titanium mahwendefa, izvo zvinogona kutariswa kune vamwe varwere.
Sei titanium mahwendefa achishandiswa pakuvhiya?
Titanium mahwendefa anowanzo shandiswa mukuvhiya nekuda kwehunhu hwawo hwakasiyana hunovaita chinhu chakanakira kuisirwa kwekurapa. Mamwe mabhenefiti ekushandisa titanium mahwendefa mukuvhiya anosanganisira:
Biocompatibility: Titanium inopindirana zvakanyanya, izvo zvinoreva kuti haigone kukonzera kusagadzikana kana kurambwa nemasoja emuviri. Izvi zvinoita kuti ive yakachengeteka uye yakavimbika zvinhu zvekushandisa mune zvekurapa anodyara.
Simba uye kusimba: Titanium imwe yesimbi yakasimba uye yakasimba, iyo inoita kuti ive chinhu chakakodzera chekudyara chinoda kushingirira kushushikana uye madhiri ekushandiswa kwemazuva ese.
Corrosion resistance: Titanium inoshingirira mukuora uye kashoma kupindirana nemvura yemumuviri kana zvimwe zvinhu zviri mumuviri. Izvi zvinobatsira kudzivirira kuisirwa kubva pakuora kana kushatisa nekufamba kwenguva.
Radiopacity: Titanium ine radiopaque zvakanyanya, zvinoreva kuti inogona kuoneka zviri nyore paX-ray uye mamwe maedzo ekufungidzira. Izvi zvinoita kuti zvive nyore kuti vanachiremba vatarise implant uye kuona kuti iri kushanda nemazvo.
Locking plates inoshandiswa nei?
Locking plates inoshandiswa mukuvhiyiwa kwemapfupa kuti ipe kugadzikana uye tsigiro kumapfupa akatyoka, akatyoka, kana kupera simba nekuda kwechirwere kana kukuvara.
Iyo ndiro inonamirwa kune bhonzo uchishandisa screws, uye screws kukiya mundiro, kugadzira yakagadziriswa-angle kuvaka inopa tsigiro yakasimba yebhonzo panguva yekupora. Locking plates inowanzoshandiswa pakurapa kutyoka kwechanza, forearm, ankle, uye gumbo, pamwe nekuvhiyiwa kwespinal fusion uye mamwe maitiro emapfupa.
Zvinonyanya kukosha mumamiriro ezvinhu apo pfupa rakaonda kana osteoporotic, sezvo nzira yekuvhara yeplate inopa kuwedzera kugadzikana uye inoderedza dambudziko rekukundikana kwekudyara.
Ko ndiro yebhonzo inoshanda sei?
Bopa ndiro chigadzirwa chekurapa chinoshandiswa kudzikamisa kuputsika kwemapfupa panguva yekupora. Icho chimedu chesimbi, chinowanzo gadzirwa nesimbi isina tsvina kana titanium, inosungirirwa pamusoro pebhonzo uchishandisa screws. Iyo ndiro inoshanda sechinhu chemukati chekubata zvimedu zvepfupa zvakaputsika mukurongeka kwakakodzera uye kupa kugadzikana panguva yekuporesa. Iyo screws inochengetedza ndiro kubhonzo, uye ndiro inobata zvimedu zvebhonzo munzvimbo yakarurama. Mapfupa emapfupa akagadzirirwa kupa kugadzirisa kwakasimba uye kudzivirira kufamba panzvimbo yekuputsika, iyo inobvumira pfupa kupora zvakanaka. Nokufamba kwenguva, pfupa rinokura rakapoteredza ndiro uye rinoribatanidza munyama yakakomberedza. Kana pfupa rapora zvakakwana, ndiro inogona kubviswa, kunyange izvi zvisingadi nguva dzose.
Ko Masiruu ekukiya inopa compression?
Masiruu ekukiya usape compression, sezvo dzakagadzirirwa kukiya mundiro uye kudzikamisa zvimedu zvemapfupa kuburikidza neyakagadziriswa-angle constructs. Kudzvinyirirwa kunowanikwa kuburikidza nekushandisa zvisiri- Masiruu ekukiya zvinoiswa mumakumbo ekumanikidzira kana maburi eplate, zvichibvumira kudzvinyirira kwemapfupa emapfupa sezvo zviputi zvakasimbiswa.
Ko ndiro nemascurus zvinokuvadza here?
Zvakajairika kunzwa kurwadziwa uye kusagadzikana mushure mekuisa ndiro uye screws panguva yekuvhiyiwa. Nekudaro, kurwadziwa kunofanirwa kudzikira nekufamba kwenguva apo muviri unopora uye nzvimbo yekuvhiya inopora. Marwadzo anogona kugadziriswa kuburikidza nemishonga uye kurapwa kwepanyama. Zvakakosha kutevera mirairo yepashure-operative inopiwa nachiremba uye kurondedzera chero kurwadziwa kunoramba kuripo kana kuwedzera kune boka rezvokurapa. Muzviitiko zvisingawanzoitiki, hardware (mahwendefa uye screws) inogona kukonzera kusagadzikana kana kurwadziwa, uye mumamiriro ezvinhu akadaro, chiremba anovhiya anogona kukurudzira kubviswa kwehardware.
Zvinotora nguva yakadii kuti mapfupa apore nema plates nema screws?
Nguva inotora kuti mapfupa apore nemahwendefa uye screws zvinogona kusiyana zvichienderana nekuoma kwekukuvara, nzvimbo yekukuvara, rudzi rwefupa, uye zera uye hutano hwese hwemurwere. Kazhinji, zvinogona kutora mavhiki akati wandei kusvika kumwedzi yakati wandei kuti mapfupa aporese zvachose nerubatsiro rwendiro uye screws.
Munguva yekutanga kupora, iyo inowanzotora mavhiki matanhatu-8, murwere anozofanira kupfeka simbi kana bhurashi kuchengetedza nzvimbo yakakanganisika isingafambi uye yakachengetedzwa. Mushure menguva iyi, murwere anogona kutanga kurapa kwepanyama kana kugadziriswa kuti abatsire kuvandudza mararamiro uye simba munzvimbo yakakanganiswa.
Zvisinei, zvakakosha kuti uzive kuti kupora hakuna kupera kana simbi yabviswa, uye zvinogona kutora mimwe mwedzi yakati wandei kuti bhonzo rigadzirise zvizere uye riwanezve simba raro rekutanga. Mune zvimwe zviitiko, varwere vanogona kunzwa kurwadziwa kwakasara kana kusagadzikana kwemwedzi inoverengeka mushure mekukuvara, kunyange mushure mekunge pfupa rapora.
