I-meniscus itholakala phakathi kwe-condyles ye-femoral medial kanye ne-lateral kanye ne-medial and lateral tibial condyles futhi ihlanganiswe ne-fibrocartilage enezinga elithile lokuhamba, elingagudluzwa kanye nokunyakaza kwamadolo ahlangene futhi idlala indima ebalulekile eboshwe ekuqondiseni nasekuqiniseni idolo elihlangene. Uma idolo lihamba ngokuzumayo futhi linamandla, kulula ukubangela ukulimala nokudabuka kwe-meniscus.
I-MRI okwamanje iyithuluzi elihle kakhulu lokuhlonza ukulimala kwamadoda. Okulandelayo yicala lokudabuka kwe-meniscal elinikezwe uDkt Priyanka Prakash ovela eMnyangweni Wezithombe, eNyuvesi yasePennsylvania, kanye nesifinyezo sokuhlukaniswa nokuthwebula izinyembezi ze-meniscal.
UMLANDO OYISISEKELO: Isiguli sasishiye ubuhlungu bedolo isonto elilodwa ngemva kokuwa. Imiphumela yokuhlolwa kwe-MRI yokuhlangana kwamadolo imi kanje.
Izici zokucabanga: uphondo olungemuva lwe-meniscus ephakathi kwedolo lesokunxele lufiphele, futhi isithombe se-coronal sibonisa izimpawu zokukhala kwe-meniscal, okwaziwa nangokuthi ukukhala okukhanyayo kwe-meniscus.
Ukuxilongwa: Ukudabuka okukhanyayo kophondo lwangemuva lwe-meniscus ephakathi kwedolo lesokunxele.
I-Anatomy ye-meniscus: Ezithombeni ze-MRI sagittal, amakhona angaphambili nangemuva e-meniscus anonxantathu, nekhona elingemuva likhulu kunekhona langaphambili.
Izinhlobo zezinyembezi ze-meniscal edolweni
1. Izinyembezi ezidabukisayo: Isiqondiso sokudabula ku-perpendicular ku-eksisi ende ye-meniscus futhi sinwebeka sibheke eceleni sisuka emaphethelweni angaphakathi e-meniscus siye kumngcele wayo we-synovial, njengokudabula okuphelele noma okungaphelele. Ukuxilongwa kuqinisekiswa ukulahlekelwa ukuma kwe-bow-tie ye-meniscus endaweni ye-coronal kanye nokufiphala kwephuzu elingunxantathu le-meniscus endaweni ye-sagittal. 2. Unyembezi oluvundlile: unyembezi oluvundlile.
2. Izinyembezi ezivundlile: Izinyembezi eziqondile ezihlukanisa i-meniscus zibe izingxenye ezingaphezulu neziphansi futhi zibonakala kangcono kuzithombe ze- coronal ze-MRI. Lolu hlobo lwezinyembezi luvame ukuhlotshaniswa ne-meniscal cyst.
3. Ukudabuka kwe-longitudinal: Izinyembezi ziqondiswe ngokuhambisana ne-eksisi ende ye-meniscus futhi ihlukanisa i-meniscus ibe izingxenye zangaphakathi nezingaphandle. Lolu hlobo lwezinyembezi ngokuvamile alufinyeleli emaphethelweni aphakathi kwe-meniscus.
4. Izinyembezi ezihlangene: inhlanganisela yalezi zinhlobo ezintathu zezinyembezi ezingenhla.
I-Magnetic resonance imaging iyindlela yokuzikhethela yezinyembezi ze-meniscal, futhi ukuze kuhlonzwe izinyembezi lezi zindlela ezimbili ezilandelayo kufanele kuhlangatshezwane nazo.
1. izimpawu ezingavamile ku-meniscus okungenani amazinga amabili alandelanayo endaweni ye-articular;
2. i-morphology engavamile ye-meniscus.
Ingxenye engazinzile ye-meniscus ivame ukususwa nge-arthroscopically.
