Ukuhlinzeka ngokuhlinzwa esikhundleni se-hi kuyinkqubo eyenziwa ekwelapheni isifo samathambo esiqinile . Kulezi ziguli ezine- arthritis ye-hip eziphazamisa imisebenzi yazo evamile futhi ezingazange zenziwe ngendlela efanele ngokwelapha okungezona okuhlinzekwa, ukuhlinzeka ngokuhlinzwa esikhundleni se-hip kungaba yindlela enhle.
Zonke iziguli zifuna ukufakwa esikhundleni se-hip ukuze kunciphise izimpawu zabo.
Kodwa-ke, bafuna ukufakelwa kwabo ukuhlala isikhathi eside - ngethemba, konke ukuphila kwabo konke. Emashumini ambalwa adlule, izimpande ezintsha zokufakelwa kwe-hip ziye zaphela futhi, zithembele ekutholeni ukuthuthukiswa kokuklama. Nakuba izimplantshi ziye zaphuthuka, zisaphelelwa amandla, okwenza odokotela neziguli banesithakazelo emiklamo emisha engabangela ukufakelwa kabusha okungcono okuhlala isikhathi eside.
Izimpande ze-Hip esikhundleni
Ukufakwa esikhundleni se-Hip kwenziwa ngokusebenzisa izifutho zokwenziwa kobuciko obuhlelekile. Ukufakela imiklamo kusukela eminyakeni yama-1960 kodwa sekuguquke ngokuhamba kwesikhathi. Amanye ama-designs asetshenzisiwe asetshenziswe amashumi eminyaka, amarekhodi amarekhodi amade, amanye amasha futhi akanakho irekhodi lomkhondo.
Iningi leziguli zinomkhuba wokufuna uhlobo olutsha lokufakelwa , ukucabanga ukuthi kungenzeka ukuthi okusha kungcono. Kodwa-ke, inzuzo eyodwa yokusebenzisa i-implant eyayizungezile yukuthi okuningi kuyaziwa ngemiphumela yesikhathi eside ne-implant.
Ukushintshwa kwama-Metal-on-Metal Hip
Ukufakwa esikhundleni se-hip-metal-on-metal kwenziwa iminyaka eminingi kepha kwathathwa kakhulu kule minyaka eyishumi edlule. Izimplantshi zensimbi-zensimbi zisebenzisa ukuklanywa okufanayo kuya endaweni ejwayelekile ye-hip , kodwa ukuphakama kokubili ibhola kanye nesokhethi kwenziwa ngensimbi. Lezi zindawo zensimbi zihlonishwa kakhulu futhi zibushelelezi.
Ngaphezu kwalokho, izakhiwo ziyinkimbinkimbi kunokwakheka kwendabuko yepulasitiki, okwenza kube lula ukugqamuka. Izindwangu zensimbi-on-metal nazo zisetshenziselwa ukufakelwa kwe- hip resurfacing implants .
Izinzuzo
Ukufakwa esikhundleni se-hi-metal-on-metal kwakhiwe ngezinzuzo ezimbili eziqondile ezikhona. Okokuqala, ubungako bhola ibhola le-ball-and-socket lingaba mkhulu. Esikhathini sendawo endabuko ye-metal-and-plastic hip, isikhwama senziwe ngepulasitiki esithatha isikhala. Ngemi-implants ensimbi-on-metal, ayikho ipulasitiki ethatha isikhala, futhi ibhola lensimbi ingaba lincane. Ibhola lezinsimbi ezinkulu lizinzile kakhulu futhi alinganiselwe ukucisha ukuhlukaniswa . Lokhu kuvame ukukhathazeka okukhulu ngeziguli ezisebenzayo.
Inkinga yesibili ukukhathazeka mayelana namazinga okugqoka. Zonke izinto ezisetshenziselwa ukushintshwa ngokuhlanganyela ziphelelwa isikhathi, ezinye zihamba ngokushesha kunabanye. Ukukhathazeka okukodwa mayelana nezimpande ze-hip metal-and-plasp ezigqoke ukugqoka eplastiki ngokuhamba kwesikhathi. Izinto ezintsha ziphenywe ukuthola izinto ezingapheli kalula. Amaplastiki amasha, amakhemikhali, nezensimbi yizo zonke izinto ezisetshenziselwa ukubhekana nalokhu okukhathazayo.
Izinkinga
Ukukhathazeka mayelana nokufakwa esikhundleni se-hip ensimbi-on-metal, ikakhulukazi ukufakelwa okwenziwe yi-Johnson & Johnson Company okuthiwa i-DePuy Orthopedics, yilokho ukufaka izimbangela kwakubangela izinkinga phakathi neminyaka embalwa yokuqala emva kokufaka esikhundleni.
Inkinga etholakala yukuthi ngenkathi izinto zingapheli masinyane, zakha izinhlayiya ezincane zezinhlayiya zensimbi. Umzimba ubonakala ubhekana nalezi zinhlayizi ezincane ngokuphendula komzimba. Lokhu kungabangela ukulimala komzimba kanye nokuthungatha amathambo nxazonke ezihlangene ne-hip. Kwezinye iziguli, lokhu kulimala kwezicubu kuye kwabangela ukulimala okungapheli futhi kudinga ukuhlinzekwa okwengeziwe . Iziguli ezinomthelela othe xaxa zivame kakhulu ukuthi zidinga ukuphindaphindiwe kwe-hip.
Iziguli ezinalezi zimila zensimbi-zensimbi nazo zitholakale zinezinga eliphezulu ze-ion zensimbi egazini labo, ubufakazi bezincane ezincane ezigqoke izinhlayiya ezibalekela emzimbeni.
Umphumela walezi zinsimbi zensimbi egazini awukwazi ukuqonda ngokugcwele, nakuba kungekho bufakazi bezinkinga kwezinye izingxenye zomzimba, umphumela kuphela ku-hip uqobo.
Okufanele Uyenze Manje
Uma unalolu hlobo oluthile lokufakelwa kabusha kwe-hip lensimbi-on-metal, kufanele uhlale ubona udokotela wakho ukuze ahlole ngokujwayelekile umjoqo we-hip. Kukhona izincomo eziqondile ezibhekene neziguli ezitholakalayo lokhu mayelana nokuthi yiziphi izivivinyo zokuhlola okufanele zenziwe, futhi uma ukuhlinzwa okwengeziwe kufanele kucatshangelwe.
Iziguli ezinamanye ama-implantant-metal-on-metal implantant implants kufanele zibonwe njalo ngodokotela wabo odokotela ukuze zihlolwe ngokuqhubekayo. Inombolo elinganiselwe yezimpembe zensimbi-zensimbi kuphela ezikhunjulwayo, futhi ngisho nalabo abafake izimpande ezikhunjulwe kungase kungadingeki zisuswe. Nokho, ngenxa yalezi zinto ezikhathazayo, lezi zimila kufanele zihlolwe ngokucophelela ukuze zibheke izinkinga ezingenzeka.
Kungani Lokhu Kwenzeke?
Kungenzeka kanjani ukuthi amashumi ezinkulungwane zeziguli athola isitshalo esagcina senzeke ukwehluleka? Lo mbuzo omuhle kakhulu, futhi lo mbhalo ukhanyisa ukukhanya okukhanyayo ohlelweni lapho amadivaysi ezokwelapha abuyekezwa futhi avunyelwe ukufakelwa.
Odokotela abahlinzayo kudingeka baqaphele izinkampani zifaka uhlelo olusha olungahle lube nolwazi lwezokwelapha. Iziguli zidinga ukufundiswa ngezingozi ezingenzeka ezinhlobonhlobo ezahlukene zezimila. Kubalulekile ukuqonda ukuthi zonke izinhlobo zokufakelwa zinokukhathazeka okuqondile, futhi ukunquma ukuthi yini engcono kakhulu kungaba inselele odokotela neziguli.
