Pankhani yamankhwala amakono, fupa lochita kupanga, monga teknoloji yofunikira yachipatala, yabweretsa chiyembekezo chatsopano kwa odwala ambiri. Mothandizidwa ndi sayansi yazinthu ndi uinjiniya wamankhwala, fupa lochita kupanga limagwira ntchito yofunika kwambiri pakukonzanso ndi kumanganso mafupa. Panthawi imodzimodziyo, anthu ali ndi mafunso ambiri okhudza fupa lochita kupanga. Mwachitsanzo, ndi matenda ati omwe ali ndi mafupa opangira? Kodi zinthu zomwe zimagwiritsidwa ntchito popanga fupa lopanga ndizowopsa mthupi la munthu? Zotsatira za mafupa ochita kupanga ndi zotani? Kenako, tidzasanthula mozama nkhani zimenezi.
Matenda oyenera kuyika mafupa ochita kupanga
Ukadaulo wopangira mafupa opangira mafupa amagwiritsidwa ntchito kwambiri pochiza matenda osiyanasiyana okhudzana ndi mafupa. Pankhani ya kupwetekedwa kwa mafupa, pamene zofooka za fupa zimayamba chifukwa cha kusweka kwakukulu, fupa lopangidwa lingagwiritsidwe ntchito ngati zinthu zodzaza kudzaza gawo losowa la fupa ndikulimbikitsa machiritso a malo ophwanyika. Mwachitsanzo, ngati wodwalayo ali ndi fracture yotseguka, fupa limawonongeka kwambiri ndipo fupa la autologous lawonongeka, ndiye kuti fupa lopangira limatha kupereka chithandizo cha malo ophwanyidwa ndikupanga microenvironment yomwe imathandizira kukula kwa maselo a mafupa.
Pankhani ya chithandizo cha chotupa cha fupa, zolakwika zazikulu za mafupa nthawi zambiri zimasiyidwa pambuyo pochotsa chotupa. Kuika mafupa ochita kupanga kungathandize kubwezeretsa mawonekedwe ndi kugwira ntchito kwa mafupa, kusunga umphumphu wa miyendo, ndi kupewa kulemala kwa mafupa chifukwa cha kuwonongeka kwa mafupa. Kuonjezera apo, mu opaleshoni ya msana, fupa lopanga nthawi zambiri limagwiritsidwa ntchito popanga lumbar fusion, anterior cervical fusion ndi ntchito zina. Ikhoza kugwiritsidwa ntchito kudzaza malo a intervertebral, kulimbikitsa kuphatikizika kwa mafupa pakati pa vertebrae, kukhazikika kwa msana, komanso kuthetsa ululu ndi zizindikiro za mitsempha ya mitsempha chifukwa cha zilonda za intervertebral disc ndi kusakhazikika. Kuonjezera apo, kwa odwala ena okalamba omwe ali ndi matenda otchedwa osteoporotic vertebral compression fractures, fupa lopangira limatha kupititsa patsogolo mphamvu ya vertebral pambuyo pa kuikidwa, kuthetsa ululu, ndi kusintha moyo wa wodwalayo.
Chitetezo cha zida zopangira mafupa opangira
Chitetezo chakuthupi cha mafupa ochita kupanga ndicho cholinga cha anthu. Pakalipano, zomwe zimagwiritsidwa ntchito kwambiri ndi mafupa opangira mafupa makamaka zimaphatikizapo zinthu za bioceramic (monga tricalcium phosphate ndi hydroxyapatite), bioglass, zipangizo zachitsulo (monga titaniyamu aloyi ndi titaniyamu) ndi zipangizo za polima (polylactic acid). Zidazi zakhala zikufufuza zambiri zoyesera komanso kutsimikizira mwamphamvu zachipatala zisanagwiritsidwe ntchito pathupi la munthu.
Zida za bioceramic zili ndi biocompatibility yabwino komanso osteoconductivity. Kapangidwe kake kake ndi kofanana ndi zomwe zili m'mafupa amunthu. Amatha kutsogolera maselo a mafupa kuti akule ndi kusiyanitsa pamwamba pa zinthuzo ndikuphatikizana pang'onopang'ono ndi thupi la munthu. Nthawi zambiri, iwo sangadzetse zoonekeratu chitetezo kukana zochita. Bioglass imakhalanso ndi zochitika zabwino kwambiri zamoyo ndipo imatha kupanga mgwirizano wamphamvu wamankhwala ndi minofu ya fupa kulimbikitsa kukonza ndi kusinthika kwa fupa. Titaniyamu aloyi ndi titaniyamu ali ndi mphamvu zambiri, kukana dzimbiri ndi biocompatibility wabwino. Amagwiritsidwa ntchito kwambiri m'magulu opangira mafupa ndi zida zopangira mafupa. Zomwe zimagwiritsidwa ntchito nthawi yayitali zachipatala zikuwonetsanso kuti ali ndi chitetezo chokwanira kwambiri. Zowonongeka za polima zimatha kutsika pang'onopang'ono kukhala mamolekyu ang'onoang'ono osavulaza m'thupi ndikusinthidwa ndikuchotsedwa ndi thupi la munthu, kupewa ngozi ya opaleshoni yachiwiri. Komabe, ngakhale kuti zinthuzi nthawi zambiri zimakhala zotetezeka, odwala ena amatha kusagwirizana ndi zinthu zina kapena amakumana ndi zovuta zina chifukwa cha kusiyana kwawo.
Zotsatira za mafupa opangira
Ngakhale kuti fupa lochita kupanga lingapangitse bwino kukonza mafupa nthawi zambiri, pangakhale zotsatira zina. Opaleshoni ya implantation palokha imakhala ndi zoopsa zina, monga matenda ndi magazi. Ngati chilondacho sichinasamalidwe bwino pambuyo pa opaleshoni, mabakiteriya amatha kulowa pamalo opangira opaleshoniyo ndikuyambitsa matenda, zomwe zimapangitsa kuti pakhale kufiira, kutupa, kupweteka ndi kutentha thupi. Pazovuta kwambiri, zingakhudze machiritso a fupa lochita kupanga ndipo zimafunikanso kuchotsa fupa lopangira kuti liwonongeke. Kuonjezera apo, pambuyo popanga mafupa opangira mafupa, odwala ena amatha kumva ululu wa m'deralo ndi kutupa, zomwe zingakhale zogwirizana ndi kupsinjika kwa thupi pambuyo pa kuikidwa kwa zinthu ndi kusintha kosinthika kwa minofu yozungulira. Kawirikawiri, ululuwo umatha pang'onopang'ono pakapita nthawi, koma mwa odwala ochepa, ululu umatenga nthawi yaitali ndipo umakhudza moyo wawo wa tsiku ndi tsiku.
Kuonjezera apo, pamafunika nthawi yochuluka kuti mafupa ochita kupanga agwirizane ndi mafupa a anthu. Ngati agwidwa ndi mphamvu zakunja kapena kuchita zinthu mopitirira muyeso panthawi ya machiritso, mafupa opangira amatha kusuntha kapena kumasula, zomwe zimakhudza kukonzanso, ndipo opaleshoni idzafunikanso kusintha kapena kukonzanso. Kuphatikiza apo, kwa mafupa ochita kupanga opangidwa ndi zinthu zowonongeka, pali kusiyana kwapayekha pamlingo wowonongeka komanso njira ya metabolic yazinthu zowonongeka. Ngati atayika mofulumira kwambiri, sangapereke nthawi yokwanira yothandizira kukonzanso mafupa. Ngati zinthu zowonongeka sizingatuluke m'thupi panthawi yake, zimadziunjikira kumaloko, zomwe zingayambitse kutupa ndi kukonzanso minofu.
In ambiri, fupa lochita kupanga limapereka chithandizo chamankhwala kwa odwala ambiri omwe ali ndi matenda a mafupa. Akagwiritsidwa ntchito pamikhalidwe yoyenera, amatha kusintha kwambiri moyo wa odwala. Ngakhale kuti zinthu zomwe zimagwiritsidwa ntchito popanga mafupa ochita kupanga nthawi zambiri zimakhala zotetezeka, pali zoopsa zina ndi zotsatira zake. Ndi kupita patsogolo kwa sayansi ndi zamakono, mafupa opangira mafupa ndi matekinoloje akuyembekezeka kukhala angwiro kwambiri m'tsogolomu, zomwe zingabweretse odwala chithandizo chamankhwala apamwamba komanso zotsatira zabwino za mankhwala.
