Φ5.0 Urukurikirane rwo hanze rwo gukosora - Ikadiri ya radiyo

Ivunika rya radiyo ya kure (DRFs) riboneka muri cm 3 z'igice cya kure cya radiyo, kikaba ari ukuvunika cyane mu gihimba cyo hejuru mu bagore bakuze ndetse n'abasore bakuze.Ubushakashatsi bwerekanye ko DRFs zingana na 17% byavunitse byose na 75% byavunitse amaboko.

Ibisubizo bishimishije ntibishobora kuboneka mugukoresha manipulative kugabanya no gutunganya plaster.Ivunika rirashobora guhinduka muburyo bworoshye nyuma yubuyobozi bwa conservateur, kandi ingorane, nko guhahamuka amagufwa hamwe no guhungabana kwamaboko, bishobora kubaho mugihe cyanyuma.Kubaga bikozwe kugirango bavure radiyo ya kure kugirango abarwayi bashobore gukora umubare uhagije wimyitozo itababaza kugirango bagarure ibikorwa bisanzwe mugihe hagabanijwe ibyago byo guhinduka cyangwa ubumuga.

Imicungire ya DRFs ku barwayi bafite imyaka 60 nayirenga ikorwa hifashishijwe uburyo butanu bukurikira: sisitemu yo gufunga plaque ya volar, kudahuza ibiraro hanze, gukosora hanze, gukosora insinga za Kirschner, no gutunganya plaster.

Abarwayi barimo kubagwa DRF hamwe no kugabanuka kumugaragaro no gukosorwa imbere bafite ibyago byinshi byo kwandura ibikomere na tendonitis.

Abatunganya hanze bagabanijwemo ubwoko bubiri bukurikira: kwambukiranya no kudahuza.Kwambukiranya-gutondekanya hanze gukosora bigabanya kugenda kwubusa kwamaboko bitewe nuburyo bwayo.Kudahuza ibyuma byo hanze bikoreshwa cyane kuko byemerera ibikorwa bike.Ibikoresho nkibi birashobora koroshya kugabanya kuvunika mugukosora ibice byavunitse bitaziguye;zemerera gucunga byoroshye ibikomere byoroheje kandi ntibibuza kugenda kwamaboko karemano mugihe cyo kuvura.Kubwibyo, kudakemura ibibazo byo hanze byasabwe cyane kuvura DRF.Mu myaka mike ishize, ikoreshwa rya gakondo yo hanze (titanium alloys) ryamamaye, kubera biocompatibilité nziza, imbaraga za mashini nyinshi hamwe no kurwanya ruswa.Nyamara, ibyuma gakondo byo hanze bikozwe mubyuma cyangwa titanium bishobora gutera ibihangano bikabije muri comptabilite ya tomografiya (CT), ibyo bikaba byaratumye abashakashatsi bashaka ibikoresho bishya kubakosora hanze.

Gukosora imbere bishingiye kuri polyetheretherketone (PEEK) byizwe kandi bikoreshwa mumyaka irenga 10.Igikoresho cya PEEK gifite inyungu zikurikira kurenza ibikoresho bikoreshwa mugukosora amagufwa gakondo: nta allergie yicyuma, radiopacity, kutivanga gake hamwe na magnetic resonance imaging (MRI), kuvanaho byoroshye, kwirinda ibintu "bikonje byo gusudira", hamwe nuburyo bwiza bwubukanishi.Kurugero, ifite imbaraga nziza zingutu, imbaraga zunama, nimbaraga zingaruka.

Ubushakashatsi bumwe bwerekanye ko abakosora PEEK bafite imbaraga, gukomera, no gukomera kuruta ibikoresho byo gutunganya ibyuma, kandi bafite imbaraga zumunaniro13.Nubwo modulike ya elastike yibikoresho bya PEEK ari 3.0-4.0 GPa, irashobora gushimangirwa na fibre karubone, kandi modulus yayo ya elastique irashobora kuba hafi yamagufwa ya cortical (18 GPa) cyangwa ikagera ku gaciro ka titanium alloy (110 GPa) na guhindura uburebure nicyerekezo cya fibre karubone.Kubwibyo, ubukanishi bwa PEEK bwegereye ubw'amagufwa.Muri iki gihe, PEEK ishingiye kuri fixeur yo hanze yarateguwe kandi ikoreshwa mubitaro.
