I-meniscus itholakala phakathi kwe-medial kanye ne-lateral femoral condyles kanye ne-medial kanye ne-lateral tibial condyles futhi yakhiwe yi-fibrocartilage enezinga elithile lokuhamba, engashukunyiswa kanye nokunyakaza kwejoyinti ledolo futhi idlala indima ebalulekile ekuqondeni nasekuzinzeni kwejoyinti ledolo. Uma ijoyinti ledolo linyakaza ngokuzumayo nangokunamandla, kulula ukubangela ukulimala kanye nokudabuka kwe-meniscus.
I-MRI okwamanje iyithuluzi elihle kakhulu lokuthwebula izithombe lokuxilonga ukulimala kwe-meniscal. Okulandelayo yindaba yokudabuka kwe-meniscal enikezwe nguDkt. Priyanka Prakash waseMnyango Wezithombe, eNyuvesi yasePennsylvania, kanye nesifinyezo sokuhlukaniswa kanye nokuthwebula izithombe zezinyembezi ze-meniscal.
UMLANDO OYISESE: Isiguli sasinobuhlungu bedolo isonto elilodwa ngemuva kokuwa. Imiphumela yokuhlolwa kwe-MRI kwejoyinti ledolo imi kanje.
Izici zezithombe: uphondo olungemuva lwe-meniscus ephakathi kwedolo lesobunxele lufiphele, kanti isithombe se-coronal sibonisa izimpawu zokukhala kwe-meniscal, okwaziwa nangokuthi ukukhala kwe-radial ye-meniscus.
Ukuxilongwa: Ukwephuka okukhulu kophondo olungemuva lwe-meniscus yangaphakathi yedolo lesobunxele.
I-Anatomy ye-meniscus: Ezithombeni ze-MRI sagittal, amakhona angaphambili nangemuva e-meniscus angunxantathu, kanti ikhoneni elingemuva likhulu kunekhona elingaphambili.
Izinhlobo zezinyembezi ze-meniscal emadolweni
1. Ukwenyuka kwe-radial: Indlela okudonswa ngayo ukudabuka iqonde ngqo ku-axis ende ye-meniscus futhi idlulela eceleni kusukela emaphethelweni angaphakathi e-meniscus kuya emkhawulweni wayo we-synovial, kungaba ukudabuka okuphelele noma okungaphelele. Lokhu kuxilongwa kuqinisekiswa ngokulahlekelwa isimo se-bow-tie se-meniscus endaweni ye-coronal kanye nokufiphala kwesihloko esingunxantathu se-meniscus endaweni ye-sagittal. 2. Ukwenyuka kwe-horizontal: ukudabuka okuvundlile.
2. Ukwenyuka okuvundlile: Ukwenyuka okuvundlile okuhlukanisa i-meniscus ibe izingxenye eziphezulu nezingezansi futhi kubonakala kahle ezithombeni ze-MRI coronal. Lolu hlobo lokukwenyuka luvame ukuhlotshaniswa ne-meniscal cyst.
3. Ukwenyuka kwe-longitudinal: Ukwenyuka kwe-meniscus kuqondiswa ngokuhambisana ne-axis ende ye-meniscus futhi kuhlukanise i-meniscus ibe izingxenye zangaphakathi nezangaphandle. Lolu hlobo lokukwenyuka kwe-meniscus ngokuvamile alufinyeleli emaphethelweni aphakathi nendawo.
4. Ukukhala okuhlanganisiwe: inhlanganisela yezinhlobo ezintathu zezinyembezi ezingenhla.
Ukuthwebula izithombe nge-magnetic resonance kuyindlela ekhethwayo yokuthwebula izinyembezi ze-meniscal, futhi ukuze kutholakale ukudabuka, lezi zindlela ezimbili ezilandelayo kufanele zihlangatshezwe.
1. izimpawu ezingavamile ku-meniscus okungenani amazinga amabili alandelanayo ebusweni be-articular;
2. ukwakheka okungajwayelekile kwe-meniscus.
Ingxenye engazinzile ye-meniscus ivame ukususwa nge-arthroscopically.
