Ukuntuleka kwegazi kuyabangela ukuthi i-Bone iyafa
I-Osteonecrosis yisimo esiphuthumayo ngenxa yokulahlekelwa okwesikhashana noma okuphakade kokunikezwa kwegazi kwithambo. Ukwehluleka kwegazi ukuhlinzeka ngamathambo kubangela ukuba ingxenye yethefu ife. Ithambo lingase liwele uma lifa, futhi uma ithambo ethintekile liseduze nehlangene, indawo ehlangene ingawa.
I-Osteonecrosis ingathinta noma yiliphi ithambo kodwa iningi liyakuthinta ukuphela kwe-femur, ithambo lesandla elingenhla, amadolo, amahlombe, nama-ankle.
I-osteonecrosis yomhlathi ibhekwa njengingavamile futhi ihlanganiswe nokusetshenziswa kwe-bisphosphonate. Nge-osteonecrosis, ithambo elilodwa lingathinteka noma ngaphezulu kweyodwa, ngesikhathi esifanayo noma ngezikhathi ezahlukene.
I-Osteonecrosis ibizwa nangokuthi i-necrosis ye-avascular, i-aseptic necrosis, noma i-necrosis ye-ischemic yethoni.
I-Osteonecrosis Injani?
I-American Academy of Orthopedic Surgeons inquma ukuthi abantu abangu-10 000 kuya ku-20 000 bakhula i-osteonecrosis unyaka ngamunye.
Yini Ebangelwa Osteonecrosis?
Ngokuvamile, ukuphazamiseka kwegazi okonakalayo okubangela i-osteonecrosis kuveza ukulimala okulandelayo (ukulimala). Noma kunjalo, kungase kube nezimbangela ezingezona ezibuhlungu.
I-osteonecrosis ehlukumezayo ivela lapho ukulimala, ukuhlukanisa noma ukulimala okuhlangene kulimaza izungeze ezungeze imithwalo yegazi, kuphazamisa ukujikeleza kwegazi emthanjeni. Ukwehlukana kwe-Hip kanye nokuqhaqhaqhaqhaza izimbangela ezivamile ze-osteonecrosis ephazamisayo.
I-osteonecrosis engenazo ezibuhlungu iqala ngaphandle kokulimala noma ukulimala.
Izimo ezithile zezokwelapha zihlotshaniswa ne-osteonecrosis engenasifo esicindezelayo njenge- lupus , gout, vasculitis , i- osteoarthritis , umdlavuza, isifo sikashukela, isifo se-Gaucher, isifo se-Cushing's, isifo sesibindi, isifo segciwane lesiguli, ukuphazamiseka kwamagciwane, izimpethu kanye nokuphazamiseka kwegazi. I-Chemotherapy, i-dose ephakeme noma ukusetshenziswa kwesikhathi eside kwe- corticosteroid , ukufakelwa komzimba, ukushisa imisebe, ukubhema nokusetshenziswa kotshwala okungapheli kubhekwa njengengozi ye-osteonecrosis.
Imithombo ethile ibheka ukusetshenziswa kwe-corticosteroid ukuze kube yimbangela evame kakhulu ye-osteonecrosis.
Ngama-20% weziguli ze-osteonecrosis, imbangela ayifakazi futhi isimo saziwa njenge-idiopathic osteonecrosis.
Izimpawu
Ekuqaleni, kungenzeka kube khona izimpawu ezibonakalayo ezihlobene ne-osteonecrosis. Kodwa njengoba isimo siqhubeka, ubuhlungu obufanayo bukhona. Ekuqaleni, ubuhlungu bungenzeka kuphela uma kuthwala isisindo, kodwa njengoba i-osteonecrosis iqhubeka, kungase kube nobuhlungu ngisho nalapho kuphumula. Ngokuhamba kwesikhathi, ubuhlungu bungakwazi ukukhawulela ububanzi bokuhamba futhi bukhubaza. Ukulahlekelwa komsebenzi ohlangene kungathuthuka esikhathini esingangezinyanga ezimbalwa. Nakuba izimpawu zivame ukuvela kancane kancane, kungenzeka ukuba uzwe ubuhlungu obungakazelelwe kusuka osteonecrosis.
Ukuxilongwa
I-X-ray iyisivivinyo sokuqala sokuxilongwa esalawulwa uma kukhona ukusola kwe-osteonecrosis. Nokho, ama-x-ray ngeke athathe izinyathelo zokuqala ze-osteonecrosis. Uma ama-x-ray ebonakala evamile, i-MRI ivame ukwenza ukunikeza ithuba elihle lokuthola izigaba zakuqala ze-osteonecrosis engakatholakali kwi-ray ray.
Nakuba zingasetshenziselwa ukuxilonga i-osteonecrosis, ukuhlola kwe-CT, ukuhlolwa kwe-bone, ne-biopsy akuvamile ukusetshenziswa.
Ukwelapha
Izinjongo zokwelashwa zihlanganisa ukuthuthukisa ukusetshenziswa komzimba ohlangene, ukuyeka ukulimala okuhlangene okunye, nokugqugquzela ukusinda kwethambo.
Uma ukhetha ukhetho olungcono kakhulu lwezokwelashwa, udokotela wakho uzocabangela ubudala bakho, isiteji se-osteonecrosis, indawo yokulimala kwamathambo, nokuthi yini eyabangela inkinga.
Kungase kube nemithi enikezwe ukunciphisa ubuhlungu, noma imithi imisiwe uma kucatshangwa ukuthi iyimbangela (isib. Corticosteroids). Ukuncipha kwesisindo kunesidingo sokuphulukisa futhi kungenziwa ngemisebenzi yokunciphisa noma ngokusebenzisa izinsimbi zomuthi noma ezinye izinsiza zokuhamba. Ukuzivocavoca okuhamba phambili ngokujwayelekile kuhlanganiswe njengengxenye yelungiselelo lokwelapha. Ukuvuselela kagesi ngezinye izikhathi kusetshenziselwa ukukhuthaza ukukhula kwethambo. Nokho, ekugcineni, iningi labantu abane-osteonecrosis lizodinga ukuhlinzeka ukuyeka noma ukuyeka ukuqhubeka kwalesi simo.
Ukwelashwa kuphumelela kakhulu uma i-osteonecrosis ingazange iqhubekele ekudlukeni kwethambo. Izinqubo ezisetshenziselwa i-osteonecrosis zibandakanya ukudonsa okuyisisekelo, i- osteotomy , i-bone graft, kanye nokuphindaphinda okuhlangene .
