I-meniscus ifumaneka phakathi kwe-condyles ye-femal medial kunye ne-lateral kunye ne-medial and lateral tibial condyles kwaye iqulethwe nge-fibrocartilage enezinga elithile lokuhamba, elinokuthi lishukunyiswe kunye nokuhamba kwedolo elidibeneyo kwaye lidlala indima ebalulekileyo edibeneyo ekululekeni nasekuzinziseni idolo elihlangeneyo. Xa idolo lihamba ngokukhawuleza kwaye linamandla, kulula ukubangela ukulimala kwe-meniscus kunye nokukrazula.
I-MRI okwangoku sesona sixhobo sibalaseleyo sokujonga ukwenzakala kwe-meniscal. Oku kulandelayo yimeko ye-meniscal tear enikwe nguGqr Priyanka Prakash kwiSebe leMifanekiso, kwiYunivesithi yasePennsylvania, kunye nesishwankathelo sokuhlelwa kunye nemifanekiso yeenyembezi ze-meniscal.
IMBALI ESISISEKO: Isigulane sasishiye iintlungu zedolo kwiveki enye emva kokuwa. Iziphumo zoviwo lwe-MRI lwamadolo ahlangeneyo lulandelayo.
Iimpawu zokucinga: uphondo lwangasemva lwe-meniscus ephakathi kwedolo lasekhohlo liphazamisekile, kwaye umfanekiso we-coronal ubonisa iimpawu ze-meniscal tear, eyaziwa ngokuba yi-radial tear ye-meniscus.
Ukuxilongwa: I-Radial tear yophondo lwangasemva lwe-meniscus yangaphakathi yedolo lasekhohlo.
I-Anatomy ye-meniscus: Kwimifanekiso ye-MRI ye-sagittal, iikona zangaphambili kunye nezingasemva ze-meniscus ziyinxantathu, kunye nekona yangasemva inkulu kunekona yangaphambili.
Iintlobo zeenyembezi ze-meniscal emadolweni
1. I-Radial tear: Isalathiso sokukrazula i-perpendicular kwi-axis ende ye-meniscus kwaye iqhubela phambili ukusuka kumgca wangaphakathi we-meniscus ukuya kumda wayo we-synovial, mhlawumbi njengokukrazula okupheleleyo okanye okungaphelelanga. Ukuxilongwa kuqinisekiswa ngokulahleka kwe-bow-tie shape ye-meniscus kwindawo ye-coronal kunye ne-blunting ye-triangular tip ye-meniscus kwindawo ye-sagittal. 2. Ukukrazuka okuthe tyaba: ukukrazuka okuthe tyaba.
2. Ukukrazula okuthe tye: Iinyembezi ezinqamlekileyo ezinqamlekileyo ezahlula i-meniscus kwiindawo eziphezulu kunye nezisezantsi kwaye zibonakala kakuhle kwimifanekiso ye-coronal ye-MRI. Olu hlobo lokukrazula ludla ngokudityaniswa ne-meniscal cyst.
3. Ukukrazula kwexesha elide: Ukukrazula kuhambelana ngokuhambelana ne-axis ende ye-meniscus kwaye yahlula i-meniscus kwiindawo zangaphakathi nangaphandle. Olu hlobo lokukrazula aluqhelekanga ukufikelela kumda we-medial we-meniscus.
4. Iinyembezi ezidibeneyo: indibaniselwano yezi ntlobo zintathu zeenyembezi.
I-imaging resonance imaging yindlela yokucinga ekhethwayo kwiinyembezi ze-meniscal, kwaye ukuxilongwa kokukrazula ezi ndlela zimbini zilandelayo kufuneka kuhlangatyezwane nazo.
1. iimpawu ezingaqhelekanga kwi-meniscus ubuncinane amanqanaba amabini alandelelanayo kwindawo ye-articular;
2. i-morphology engaqhelekanga ye-meniscus.
Inxalenye engazinzanga ye-meniscus idla ngokususwa i-arthroscopically.
