Chii chinonzi mini fragment?
Mini fragment inoreva rudzi rweothopedic implant inoshandiswa kugadzirisa mabhonzo madiki nezvidimbu zvebhonzo, kazhinji izvo zvinoyera 2.0 kusvika 3.5 mm mudhayamita. Aya ma implants anowanzoshandiswa mukuvhiya kwemaoko netsoka, pamwe nekumwe kuvhiya kunosanganisira zvidimbu zvidiki zvemapfupa. Mini fragment implants yakagadzirirwa kupa yakagadzikana kugadzirisa uye kukurudzira kuporeswa, uye inowanikwa mumhando dzakasiyana siyana uye saizi kuti igadzirise zvinodiwa zvekuvhiya zvakasiyana. Iwo anowanzo gadzirwa ne biocompatible zvinhu senge titanium kana simbi isina tsvina, uye anowanzo kuisirwa uchishandisa hunyanzvi zviridzwa.
Ndedzipi mhando dzemini fragment?
Mini fragment plates inowanikwa mumhando dzakasiyana uye saizi kuti ikwane nzvimbo dzakasiyana dzeanatomical uye saizi yebhonzo. Mamwe marudzi akajairika emamini fragment mahwendefa anosanganisira:
Chetatu chetubular plates: Aya anoshandiswa kune zvimedu zvebhonzo zvidiki kana zvimedu zvidiki zvebhonzo zvine nzvimbo shoma yekugadzirisa, senge muruoko, wrist, uye chiziso.
T-mahwendefa: Aya mahwendefa anowanzo shandiswa mukutsemuka kweiyo distal radius, ankle, uye calcaneus.
L-mahwendefa: Aya mahwendefa anoshandiswa mukuputsika kunoda kugadziriswa perpendicular kune yakareba axis yepfupa, senge mu distal femoral fractures.
H-mahwendefa: Aya mahwendefa anoshandiswa mukuputsika kweproximal tibia, pamwe chete nekurapa kwevasiri masangano.
Y-mahwendefa: Aya mahwendefa anoshandiswa pakutsemuka kweproximal humerus, clavicle, uye distal femur.
Hook plates: Aya mahwendefa anoshandiswa mukutsemuka kwakaoma uko maitiro ekugadzira akajairwa haagoneke kana kutadza, senge mukutsemuka kwe lateral tibial plateau.
Izvo zvakakosha kuti uzive kuti mhando uye saizi yemamini fragment mahwendefa anoshandiswa zvinoenderana neiyo chaiyo yekutyoka pateni uye nezvinodiwa nachiremba wekuvhiya.
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 inovimbika zvinhu zvekushandisa mumishonga inodyara.
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.
