Bukaannada ku dhow in la beddelo misigta ama ka fikiraya beddelka miskaha mustaqbalka, waxaa jira go'aamo badan oo muhiim ah oo la sameeyo. Go'aanka muhiimka ah waa doorashada dusha kaaliyaha prosthetic ee beddelka wadajirka ah: birta-ku-salaysan, birta-ku- polyethylene, ceramic-on-polyethylene, ama ceramic-on-ceramic. Mararka qaarkood, tani waxay noqon kartaa laba daran mid dooro!
Wadarta qalliinka beddelka misigta waxaa loo isticmaali karaa in lagu beddelo wadajirka miskaha ee arthritic, iyadoo la isticmaalayo sanaaci la-goysyada macmalka ah si loo baabi'iyo xanuunka ay sababto xoqidda sagxadaha.
Sawirro-is-goysyada macmalka ah waxaa loogu talagalay inay siiyaan bukaannada xasillooni weyn iyo daal iyo dillaac yar. Bir dhaqameedka iyo maqaaradaha polyetylen-ka ayaa la isticmaalayey ilaa 1960-meeyadii, laakiin horumarka tignoolajiyada ayaa horseeday in dhoobada iyo walxaha kale ay noqdaan kuwo caan ah.
Walxaha maqaar-galaha beddelka wadajirka miskaha
Mid ka mid ah dhibaatooyinka ugu caansan ka dib beddelka miskaha waa xiritaanka iyo jeexjeexa sanaaci wadajirka ah ee isticmaalka caadiga ah. Iyada oo ku xidhan duruufaha gaarka ah ee bukaanka, sida da'da, cabbirka, heerka dhaqdhaqaaqa, iyo khibradda dhakhtarka qalliinka ee maqaar-galaha gaarka ah, sanaaci beddelka miskaha waxaa laga yaabaa in laga sameeyo bir, polyetylen (caag), ama dhoobo ah. Tusaale ahaan, haddii bukaanku aad u firfircoon yahay ama aad u yar yahay oo u baahan yahay dhaqdhaqaaq heer sare ah qaliinka ka dib, dhakhtarka lafaha ayaa ku talin kara miskaha dhoobada ah.

Kubadaha birta ah ee caadiga ah iyo koobabka polyetylenka ayaa la isticmaalayey ilaa horraantii 1960-meeyadii. Cilmi-baadhis sayniseed ayaa muujisay in isticmaalka xadhkaha polyetylen-ka ee la hagaajiyay, oo loo yaqaan "xadhkaha aadka isku-tallaabta" ee polyetylen, ay si weyn u yareeyn karto heerka xirashada guud ee rakibidda. Sababtoo ah adkeysigeeda iyo guryaha kale ee la xidhiidha, polyetylen macdan ah ayaa ahaa walxaha doorashada dhakhaatiirta lafaha ee qaybaha sinta macmalka ah tan iyo markii ugu horeysay ee qaliinka bedelka miskaha la sameeyay. Kubadda birta ah waxay ka samaysan tahay kobalt-chromium alloy, dahaarkana wuxuu ka samaysan yahay polyetylen.

Talooyinka dhoobada ayaa ka adag birta waana walxaha ugu adkaysiga badan ee la gashado. Ceramics-ka hadda loo isticmaalo qalliinnada beddelka wadajirka ah waxay leeyihiin meelo adag, xoqan u adkaysta, sagxadaha aadka u jilicsan oo si weyn u yarayn kara heerka xidhashada isku-xidhka isku-xidhka polyetylenka. Heerka xidhashada suurtagalka ah ee maqaar-galahani wuu ka hooseeyaa heerka daalashada birta ee polyetylen.

Isku-dhafka birta-on-birta isku-dhafka ah (cobalt-chromium alloys, marmarka qaarkood birta) ayaa la isticmaalay horraantii 1955, laakiin ma aysan ansixin FDA si loogu isticmaalo Maraykanka ilaa 1999. Sida horumarinta tiknoolajiyada, xirashada si weyn ayaa loo dhimay, taasoo keentay in barar yar iyo lafo lumis. Biraha birta ayaa lagu heli karaa cabbirro kala duwan (laga bilaabo 28mm ilaa 60mm), iyo sidoo kale noocyo kala duwan oo dhererka qoorta ah. Si kastaba ha ahaatee, warbixinnada muddada dheer ee qalliinka ka dib ayaa tilmaamaya in birta, sida ion firfircooni ah, ay ururiso qashinka birta sababtoo ah jeexjeexa muddada dheer iyo jeexjeexa, taas oo horseedi karta kala-baxa lafaha agagaarka sanaaci la-goysyada, ugu dambeyntiina waxay keentaa dabacsanaan iyo qallafsanaanta sanaaci wadajirka ah. Hawlgalku wuu fashilmay.
4、 madaxa kubbadda dhoobada iyodahaarka dhoobada
Sintahan, kubbadaha biraha dhaqameed iyo xayndaabyada polyetylenka ayaa lagu beddelay ceramics-xoog badan, kuwaas oo loo yaqaanno sifooyinkooda aadka u hooseeya. Si kastaba ha noqotee, iyada oo leh faa'iidooyinka tayada sare iyo hoos u dhaca, waxay sidoo kale si lama filaan ah u leeyihiin faa'iido darrooyinka qiimaha sarreeya.
Doorashada kama dambaysta ah ee maqaar-galaha waxa lagu go'aamin doonaa iyadoo lagu salaynayo arrimaha caafimaadka gaarka ah ee bukaan-socodka waxayna sidoo kale u baahan doontaa khibradda, waxbarashada, iyo khibradda dhakhtarka lafaha si uu u habeeyo badeecada soo saaraha gaarka ah. Sidaa darteed, waa lagama maarmaan inaad kala hadasho dhakhtarkaaga lafaha qalliinka ka hor si aad u fahamto nooca maqaar-galaha ay doonayaan inay u isticmaalaan qalliinka beddelka miskahaaga, iyo sababaha loo doorto maqaar gaar ah.
