Avascular Necrosis yechiri
Hip osteonecrosis, iyo inonziwo avascular necrosis, ichinetso neropa rinopa pfupa rekuputika . Izvi zvinowanzoitika kana kune kukanganisa kwekuyerera kweropa kusvika kumusoro wevakadzi (ibhola, yebhoti-uye-yakagadzikana hip joint). Kushaikwa kweropa rega rega kumasero emapfupa kunokonzera kuderera kwekutora oksijeni nemuviri kumapfupa, uye masero emapfupa anozofa.
Apo masero emapfupa ari kukuvadza, simba refupa rakanyanya kuderera, uye pfupa rinogona kuparara.
Zvinokonzera
Hapana anoziva chaizvo chinokonzera hip osteonecrosis. Kana chiuno che osteonecrosis chikaitika, pfupa rinoputsika uye kubatana kwepamusoro, goroti, rinorasikirwa nekutsigirwa kwayo. Nemhaka yokuti goroti rinorasikirwa nerutsigiro rwepfupa riri pasi, kubatana kwepasi kunokurumidza kupera, uye arthritis inokura nokukurumidza.
Vakawanda varwere vane hip osteonecrosis vanobatanidzwa pamwe nekudhakwa kana kushandiswa kwechirotero . Zvimwe zvinokonzera njodzi dzekunyora hip osteonecrosis dzinosanganisira sickle cell disease, kushungurudzika kune hip (dislocation kana kuputsika), lupus, uye zvimwe zvinokonzera zvirwere.
Zviratidzo
Hip osteonecrosis inowanzo ine zviratidzo zvishomanana zvinonyevera. Varwere vanowanzonyunyutira kurwadziwa kwekutanga kwehup uye kutambudzika kufamba. Zviratidzo zvinowanzoitwa hip osteonecrosis zvinosanganisira:
- Kurwadziwa mumupuranga
- Pain nekufamba kwechiuno
- Kuoma kufamba kana kuora
Iko miviri miviri inobatsira zvikuru pakuongorora nekurapa hip osteonecrosis ndeye x-ray uye MRIs . I-ray-ray inogona kuva yakakwana, kana inogona kuratidza kukanganisa kwakanyanya kumubatanidzwa wehudyu. Kana i-x-ray yakajairika, i-MRI inogona kuitwa kuitira kutarisa zviratidzo zvokutanga zvechiuno osteonecrosis.
Kutanga osteonecrosis yehudyu inogona kunge isingaratidziki pamutambo x-ray, asi inofanira kuonekwa nguva dzose pamutambo weMRI. Zvishoma zvikamu zve osteonecrosis zvinongoratidzika pachena pa x-ray, uye MRIs hazvidiwi uye hazviwanzobatsiri. Zvinosuruvarisa, kazhinji nenguva iyo hip osteonecrosis inoratidzwa pa x-ray, mishonga chete yekuvhiya iyo inogona kuwanika ndiyo inogadzirisa mitemo.
Mamwe mamiriro ezvinhu angave ane zviratidzo zvakafanana zvinosanganisira osteoarthritis yehudyu , nguva inotevera osteoporosis yehudyu , uye zvinetso kumashure .
Kurapa
Kurapa kwehapi osteonecrosis kwakaoma nokuti dambudziko rinowedzera kubudirira nokukurumidza pasinei nekupindira. Muchikamu chekutanga chechiputi che osteonecrosis, mishonga uye anti-inflammatory medication zvinogona kubatsira.
Zvokuvhiya zvinoshandiswa mumatambo okutanga ehup osteonecrosis zvinosanganisira hip decompression uye bone kubatanidza. Kudzvinyiririka kwechi Hip kwakaitwa kuitira kuti kuderedzwa kuwedzerwa mukati memusoro wechikadzi kunogona kuve kuchiita kushayikwa kweropa rega rega. Kushongedzerwa kwechiuno kunoitwa nemurwere akarara muimba yekushandisa. Makomba maduku akadonhedzwa munzvimbo ye hip osteonecrosis kuti abvise kudzvinyirirwa mukati memusoro wevakadzi.
A vascularized bone graft inotapira bone rune utano kubva pamakumbo apasi (pamwe chete nemidziyo yeropa inowanikwa pfupa), uye inoisa izvi munzvimbo ye hip osteonecrosis.
Chinangwa chekuvhiya uku ndechekupa ruzivo rwese rwemuropa kusvika kumucheka wakabatwa. Nyanzvi dzechiremba dzakaedzawo mamwe maitiro ekubatanidza (kusanganisira cadaver bone uye synthetic grafts) kukurudzira kuporesa kwefupa mumusoro wechikadzi. Aya maitiro anongowanikwa chete mumatanho ekutanga e hip osteonecrosis; kana katetilage kakatowa, ikozvino chirwere ichi chinogona kunge chisina kubudirira.
Chirwere chinowanzoitwa kurapwa kwe hip osteonecrosis chizere zvachose chokudzoka . Kana pane kukanganisa kumusana wehutachiwana, ipapo kubvisa mhuka kunogona kunge kwakanakisisa. Kunyange zvazvo kushandiswa kwechikafu kuchiita zvakanaka, kushandiswa kunopedzisira kwapera nguva.
Izvi zvinokonzera dambudziko guru muvatana vaduku vanonzi vane hip osteonecrosis. Imwe nzira yevaduku vaduku inonzi hip resurfacing surgery . Iyi nzira yakafanana neyakashandurwa yakasara , asi inobvisa pfupa duku.
