I-annulus fibrosus iyimbumbulu eqinile eyenza ingxenye yangaphandle ye-disc intervertebral. Umsebenzi wayo ukuqukatha nokuvikela impahla elula ephakathi kwediski. Lesi sikhungo esithambile sibizwa ngokuthi i- nucleus pulposus . I-nucleus pulposus (nayo yonke i- disc intervertebral ) ihlinzekela ukumangalisa okwenziwe umgogodla.
I-annulus, njengoba ibizwa ngokuthi iyifushane, iqukethe izindandatho eziningana ezigxilwe nge-fibrous cartilage esekelwe engxenyeni ye-diagonal.
Ama-fibers ohlangothini ngalunye oluhlukile lonyaka ogijimayo egijima ngakwesokudla kuya emafibeni endandeni eduze kwawo. Lokhu kukwakhiwa kwe-scaffolding kwandisa amandla we-annulus fibrosus yonke, ukuyivumela ukuba ifeze injongo yayo njenge-container ye-nucleus pulposus.
Izinyembezi Zengane
Ukulimala okuvamile ku-annulus kuyinyembezi. Izinyembezi zingaba zibuhlungu noma zingabonakali. Izinyembezi eziningana ngezinye izikhathi ziholela ekudleni noma kwi-discni, kodwa hhayi ngaso sonke isikhathi.
Ngokuvamile, izinyembezi zingaphathwa ngempumelelo ngaphandle kokuhlinzwa ; ngamanye amazwi, ukwelashwa ngokomzimba, ukuvivinya umzimba, izindlela zokwelashwa eziphelele kanye nemithi ingase ibe ngokwanele ukukhulula izimpawu zakho.
Esikhathini esiningi, ukwelashwa kwe-disc intervertebral kugxile ekuqukethe (noma ukucima izingcezu) i-nucleus pulposus.
Kodwa maduzane nje, ososayensi nabahlengikazi bebelokhu besebenza ngezindlela zokuqinisa futhi / noma ukulungisa lo msulwa. Ngokwe-athikili ka-Mashi 2009 kaBron, et.
al. eshicilelwe kuyi- European Spine Journal, indlela entsha yokuvuselela egxile ebucayi bezintambo zomuntu ongekho emthethweni kungadingeka ukuze kuvinjelwe ukuvuselelwa kabusha. Abalobi abathi ukuqinisa nokulungisa umonakalo kungase kwandise amandla okuvuselelwa kwe-nucleus pulposus.
Ngaphandle kokulungiswa nokuqiniswa, ziyaqhubeka, isilinganiso esivamile sokucindezeleka kwe-disc (okuyinto edingekile ekusebenzeni okukhulu kwe-diski yokukhwabanisa) ayikwazi ukubuyiselwa.
Lesi siqondiso esisha sisencane, okusho ukuthi ngenkathi sekuvivinywa izilwane, ukwelashwa okusebenza kubantu kusesezindleleni. Okwamanje, nansi iBron, et. uhlu lwazo zonke izindlela zokususa ukuqinisa nokulungisa:
Indlela Yokuhlinzeka Yokulungiswa Kwe-Annulus
Suturing, ngokusho Bron, et. al. iklanyelwe ukuba iqukathe i-nucleus pulposus ekusebenzisweni kwe-dis replacement. Kodwa ayibuyiseli izintambo ezilahlekile, futhi azibuyiseli noma yimuphi umonakalo. Abacwaningi bathi imikhiqizo eminingi isivele isetshenziswa ngesikhathi sokuhlinzwa ekhuluma ngalezi zinkinga; Ngokufanayo, benza abacwaningi besikhathi esizayo ukuthi babe nezindlela eziphumelelayo nakakhulu.
Ukuvuselelwa kuka-Annulus Fibrosus
Ukuvuselela izintambo zomuntu ongenakho, ngokusebenzisa ubuciko bokuziphathekayo, ngezindlela ezithile, ngokusho kweBron, et. I-al., isisombululo esingcono kunokuba suturing. Inkinga yukuthi, kunzima kakhulu ososayensi ukuphuma. Lezi zinhlobo ezintathu zezindlela ezisemisebenzini yilezi: Ukudala amaseli we-annulus, besebenzisa izici zegeni nezibi ezisebenzayo ukuze zithinte umkhiqizo we-matrix owengeziwe, nokweqa.
Ngokufanelekile, abacwaningi bathi, isu lokuvuselelwa kwe-annulus lizohlanganisa amasu agcina izinyembezi nokuvuselela izicubu ngesikhathi esisodwa. Bathi futhi amaqhinga nezakhi eziphilayo azikwazi ukusetshenziswa njengezokwelapha okumele zenzeke, kepha kunalokho zihambisana nokugcoba.
