I-Orthopedic Bone I-Cementity yintonga yezonyango isetyenziswe ngokubanzi kwi-Ortoric. Isetyenziselwa ikakhulu ukulungisa i-Prostheses edibeneyo yokufakelwa, gcwalisa ii-bone ezinesiphene, kwaye ubonelele ngenkxaso kunye nokulungiswa kwonyango lwefradisiweyo. Igcwalisa umsantsa phakathi kwamajoyina afanelekileyo kunye nezicubu zethambo, inciphisa ukunxiba kwaye isasaze uxinzelelo, kwaye iphucule isiphumo sonyango oludibeneyo.
Eyona nto iphambili ekusetyenzisweni kwezipiki zethambo zezi:
I-1. Ukulungisa ububi: I-CADE yethambo inokusetyenziselwa ukugcwalisa kunye nokulungisa iindawo zokuqhekeka.
2. Utyando we-Orthoperic: Ngonyango lwe-Ortopedic, iCone yeXesha lisetyenziselwa ukulungisa kunye nokwakha kwakhona umphezulu odibeneyo.
3. I-Bone Deender: I-Bone yeXesha linokugcwalisa iziphene zethambo kwaye ikhuthaze ukuvuselelwa kwe-tism.
Ngokufanelekileyo, isamente yethambo kufuneka ibe neempawu ezilandelayo: (1) I-Traftical eyaneleyo, iipropathi ezinokufumaneka, ubumbano, kunye ne-radiocacity yezinto eziphathwayo; (2) amandla omatshini ofanelekileyo wokuqiniswa kwangoko; . . . kunye (6) nezakhono ezifanelekileyo zokuzizuzisa iziyobisi.
Ngeminyaka yee-1970, isamente yethambo yayisetyenziselwedibanisaUkulungiswa kwe-Prosthesis, kwaye kunokusetyenziswa njengesiza sokugcwaliswa kwezicubu kunye nokulungisa izinto ezikwi-ortopedic kunye namazinyo. Okwangoku, ezona zinto zisetyenziswa kakhulu kwaye eziphandiweyo zibandakanya i-polymethyl metacrylate (PMMA) ithambo, i-calcium phosfate bone cement yesamente. Okwangoku, iintlobo ezisetyenziswayo zethambo ezisetyenzisiweyo zibandakanya i-polymethyl metacrylate (PMMA) I-COE yethambo, i-Calcium phosfate Bone i-Clomes, i-Calcium cemet ye-Caldium yeXesha le-Calmaum yeXesha le-Calmaum kunye ne-Calcium yeXesha le-Calmaum kunye ne-Calcium yeXesha le-Calmaum. Nangona kunjalo, i-calcium ye-calcium yesamente inomsebenzi webhayiloji engalunganga kwaye ayinakho ukwenza imichiza yekhemikhali phakathi kwe-calcium grafts kunye nezicubu zethambo, kwaye ziya kuncipha ngokukhawuleza. I-Calcium I-Calcium ye-Callite I-Ceme inokufakwa ngokupheleleyo kwisithuba seeveki ezintandathu emva kokufakwa emzimbeni. Oku khupha ngokukhawuleza akuhambelani nenkqubo yokwenziwa kwethambo. Ke ngoko, xa kuthelekiswa ne-Calcium phosphate bone upmentwana, uphuhliso kunye nokusetyenziswa kweklinikhi ye-calcium ye-calcium ye-calcium ye-calcium ye-calcium inomda. I-PMMA BEE ye-COE ye-acrylic polymer eyenziwe ngokuxuba izinto ezimbini: i-methyl ye-methyl methyl metacrylate kunye ne-methyl methyl methacrylate-styrene copolymer. Inentsalela ephantsi kakhulu entsalela, ukuchasana nokutyeshela okuphantsi kunye nokuxinanisa, kwaye kunokukhupha ukwenziwa kwethambo elitsha kwaye kunciphise isimo sokuphendula esineziphako kunye nepleyiti eziphezulu kakhulu. Elona candelo liphambili lomgubo wayo yi-polymethyl metacrylate okanye i-methyl metacrylate-styrenes, kunye necandelo eliphambili lolwelo yiMethyl Metacrylate.
I-PMMA BOE yesamente inamandla aphezulu kunye neplastiki, kwaye iqinile ngokukhawuleza, ngenxa yokuba izigulana zinokuphuma ebhedini kwaye zenze imisebenzi yokubuyisela kwimeko yesiqhelo emva kotyando. Ineplasitiki egqwesileyo, kwaye umqhubi unokwenza nayiphi na iplastiki ngaphambi kokuba isamente yethambo siyaziqinisa. Umxholo unentsebenzo elungileyo yokhuseleko, kwaye ayihlanjwanga okanye ayinamhlathisi umzimba emva kokwenza emzimbeni. Isakhiwo sekhemikhali sizinzile, kwaye iipropathi zoomatshini ziyaqwalaselwa.
Nangona kunjalo, isenayo into engalunganga, njengokuba ingabangela uxinzelelo oluphezulu kwi-bone marrow cavity ngexesha lokugcwalisa, kubangela imithambo yegazi kwaye ibangele i-embolism. Ngokungafaniyo namathambo abantu, amalungu anokufakelwa usenokuba kukhululeka ekuhambeni kwexesha. I-PMMA MoNomers ikhuphe ubushushu ngexesha lokugcwaliswa kwe-polymerization, enokubangela ukonakala kwizicubu ezijikelezileyo okanye iiseli. Izixhobo ezenza i-cemeng yethambo zine-cytotocity ethile, njl.
Izithako ezikwi-Bone i-CATE zinokubangela izinto eziphathwayo, ezinje ngokungxama, i-rash, i-DYSPANA nezinye iimpawu, kunye neemeko ezinzima, i-Anaphylactic Yothusa. Uvavanyo lwe-allergy kufuneka lwenziwe ngaphambi kokuba lusetyenziswe ukunqanda ukusasebenzi. Ukuphendula okungapheliyo kwi-CloEmenti yeXesha lokuSebenza, ukuvuza kwethambo leXesha, ukuKhangela kweBene Class kunye nokuFulwa. Ukuvuza kwethambo ukuvuza kunokubangela ukuvuvukala kwezicubu kunye nokusabela kwetyhefu, kwaye kunokwenzakalisa irves kunye nemithambo yegazi, kukhokelela kwiingxaki. Ukulungiswa kwe-ceng yethambo kunokuthenjwa kwaye kungahlala ixesha elingaphezu kweminyaka elishumi, okanye ngaphezulu kweminyaka engamashumi amabini.
Ithambo lophuhliso lwethambo luphango oluqhelekileyo oluhlaselayo, kwaye igama layo lesayensi yi-vertebraplasy. I-fumeme yethambo yinto ye-polymer ngolwelo oluhle ngaphambi kokuqiniswa. Inokufaka ngokulula i-vertebrae ngokusebenzisa inaliti, kwaye emva koko ihlukumeze i-vertebrae yangaphakathi ye-vertebrae; I-fumeme yethambo iqinisa malunga nemizuzu eli-10, inamathela imingxunya emathanjeni, kwaye isamente enzima yesamente inokudlala indima exhasayo ngaphakathi kwamathambo, esenza i-vertebrae eyomeleleyo. Yonke inkqubo yonyango ithatha kuphela imizuzu engama-20 ukuya kwengama-30.
Ukwenzela ukuthintela ukuhluthwa emva kwenaliti yethambo, uhlobo olutsha lwesixhobo senziwe, oko kukuthi, isixhobo se-vertebroplast. Yenza i-tuction encinci kumqolo wokubuya komguli kwaye isebenzise inaliti ekhethekileyo yokuphononongwa komzimba we-vertebral ngolusu phantsi kolusu phantsi kwe-X-ray phantsi kwejelo lokusebenza. Emva koko iBalloon ifakwe ukuba ibule umzimba ophucukileyo we-vertebral, kwaye ke i-bone igcinwe kwiqumrhu le-vertebral ukubuyisela umzimba we-vertebral of thertebral. Ithambo elinqamlezileyo kumzimba we-vertebral liqokelelwa ngu-Balloons ukwenza umqobo ukwenza umqobo ukuthintela ukuvuza kwethambo, ngelixa kuncitshiswa koxinzelelo kwinaliti yethambo, ngokokunciphisa kakhulu ithambo. Inokunciphisa imeko yezicelo ezinxulumene nokuphumla kwebhedi, ezinjenge-pumonia, izilonda zoxinzelelo, kunye nokuthintela umjikelo ombi we-osteoporosis ngenxa yokuphumla kwebhedi yexesha elide.
Ukuba utyando lwe-PKP lwenziwa, isigulana kufuneka siphumle ebhedini ngaphakathi kweeyure ezi-2 emva kotyando, kwaye sinokujika kwi-Axis. Ngeli xesha, ukuba kukho nayiphi na imvakalelo engaqhelekanga okanye iintlungu ziyaqhubeka, kwagqirha kufuneka zaziswe ngexesha.
Phawula:
① Khusela ujikelezo olukhulu lwe-waike kunye nokugoba imisebenzi yokugoba;
② Kulumkele ukuhlala okanye ukuma ixesha elide;
③ Khusela ukuthwala ubunzima okanye ukugoba ngaphezulu ukuze uthathe izinto emhlabeni;
④ khusele ukuhlala kwisitulo esisezantsi;
⑤ Ukuthintela ukuwa kunye nokuphinda uphuphume.
