Chii chinonzi Small Fragment?
Diki fragment (Diki fragment) inoreva rudzi rweothopaedic implant inoshandiswa kugadzirisa tyoka kana kuremara mumabhonzo madiki kana munzvimbo dzine zvishoma zvinyoro zvinyoro. Aya ma implants akagadzirirwa kupa kugadzirisa kwakagadzikana uye kubvumira kukurumidza kuunganidza uye kukurumidza kupora. Zvimedu zvidiki zvinodyarwa kazhinji zvine dhayamita ye3.5mm kana zvishoma uye zvinowanikwa mumhando dzakasiyana uye saizi, kusanganisira screws, marata, uye waya. Izvo zvinowanzoshandiswa mumatanho akadai sekuvhiyiwa kwemaoko netsoka, kuputika kwemakumbo, uye clavicle fractures.
Zvishandiso zvekuvhara ndiro?
Mapureti ekukiya 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 zvakanakira kushandiswa mukudyara kwemapfupa. Mukuwedzera, ivo vane inert uye havaiti pamwe nemuviri wenyama, kuderedza dambudziko rekuramba kana kuzvimba. Mamwe mahwendefa ekuvhara anogona zvakare kuputirwa nezvinhu zvakaita sehydroxyapatite kana mamwe machira kuti avandudze kubatanidzwa kwavo nefupa matishu.
Ndeipi ndiro iri nani titanium kana simbi isina tsvina?
Mahwendefa etitanium nesimbi asina tsvina anowanzo shandiswa mukuvhiyiwa kwemapfupa, kusanganisira kukiya mahwendefa. 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 chinopindirana uye chinoshingirira mukuora, zvichiita kuti ive sarudzo yakanaka kwazvo yekudyara. 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 mukugadzirwa kwemapfupa 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 nekugara kwenguva refu: 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.
Marata ekukiya anoshandiswa chii?
Mahwendefa ekuvhara anoshandiswa mukuvhiya kwemapfupa kuti ape 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. Kukiya mahwendefa anowanzoshandiswa mukurapa kuputsika kwechanza, forearm, ankle, uye gumbo, pamwe nekuvhiyiwa kwespinal fusion uye mamwe maitiro emapfupa.
Izvo zvinonyanya kukosha mumamiriro ezvinhu apo pfupa rakatetepa 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 kukiya screws inopa compression?
Locking screws haipe compression, sezvo yakagadzirirwa kukiya mundiro uye kudzikamisa zvidimbu zvemapfupa kuburikidza neyakagadziriswa-angle constructs. Kudzvinyirirwa kunowanikwa kuburikidza nekushandisa zvisiri-kukiya screws anoiswa mu compression slots kana maburi eplate, zvichibvumira kudzvanywa kwemapfupa ezvimedu sezvo screws dzakasimbiswa.
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 kuudza 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 kubvisa hardware.
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 akawanda kusvika kumwedzi yakawanda kuti mapfupa apore zvachose nerubatsiro rwemahwendefa 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 kurapwa kwepanyama kana kugadziriswa kuti abatsire kuvandudza mararamiro uye simba munzvimbo yakakanganiswa.
Zvisinei, zvakakosha kuziva 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.
