Ukulimala kwalezi ziqinisi ezingaphakathi kwe-Knee Joint
I-ligament ye-collateral ligament (i-MCL) ingenye yemigqa emine emikhulu ebaluleke kakhulu ekuqineni kwamadolo . I-ligament yenziwe ngezinto ezinzima ezinamafrifu nemisebenzi yokulawula ukunyakaza ngokweqile ngokunciphisa ukuhamba okuhlangene. Amagundane amane amakhulu okuzinzisa emadolweni yi-ligaments yangaphambili neyasemuva (i- ACL ne- PCL ), kanye nemigqa ye-collateral ligaments (i-MCL ne- LCL ).
I-MCL ihlukanisa ibanga kusukela ekupheleni kwe-femur (ithambo lesithambo) phezulu kwe-tibia (ithambo lesifuba) futhi lingaphakathi lamadolo . I-MCL imelana nokukhulisa ngaphakathi kwe-joint, okungacatshangwa njengokuvimbela "ukuvuleka" kwamadolo. Uma i-MCL idwenguliwe ngokuphelele, ukulimala kuzobangela ukuthi uhlangane ube nama-2 degrees engeziwe kuya ku-5 degrees of laxity. Uma ezinye izicubu ezincane ezizungezile zonakalisiwe, khona-ke inani laxity lizophindwa kabili. I-MCL akuyona kuphela into yokuvimbela ukuvulwa ngokweqile engxenyeni yangaphakathi yamadolo, kodwa kuyisivimbela esiyinhloko kulokhu kuhamba.
Izinyembezi ze-MCL
Ngenxa yokuthi i-MCL igwema ukujula ngaphakathi kwehlangothini lamadolo, i-ligament ivame ukulimala uma ngaphandle kwegceke elihlangene lishaywa. Leli gunya lenza ukuba ngaphandle kwamadolo kuqhume, kanti ngaphakathi ukukhulisa. Uma i-MCL isule kakhulu kakhulu, iyakwazi ukudubula nokulimala.
Lokhu ukulimala okubonwe yisenzo sokuthi " ukuchofoza " emdlalweni webhola lebhola.
Ukulimala ku-MCL kungase kwenzeke njengokulimala okukude, noma kungase kuyingxenye yokulimala okuyinkimbinkimbi emadolweni. Eminye imigamu, ngokuvamile i-ACL, noma i -meniscus , ingase ikhishwe kanye nokulimala kwe-MCL.
Ukuze kuvimbele ukuthi kungenzeka izinyembezi ze-MCL, abanye abagijimi basebenzisa amabhande ukuze avimbele amandla amaningi ngokwemigqa.
Lezi zivame kakhulu ukugqoka abadlali bebhola laseMelika, ikakhulukazi i-lineman. Labagijimi bavame ukuxoshwa emadolweni amakhulu, indlela engabangela ukulimala kwe-MCL. Ukusetshenziswa kwale mibhoshongo kuyindaba yokuphikisana, kodwa mhlawumbe kukhona inzuzo encane ngokuvimbela amathuba okulimala uma i-brace igqoke kulezi zimo.
Izimpawu zezinyembezi ze-MCL
Uphawu oluvame kakhulu emva kokulimala kwe-MCL ubuhlungu ngqo phezu kwegamento. Ukuvuvukala kungase kubonakale phezu komgudu oqhekekile, futhi ukulimaza nokuvuvukala okuhlangene okuvamile kufinyelela ezinsukwini ezimbili emva kokulimala. Lapho belimala kakhudlwana, iziguli zingase zikhononde ngokuthi amadolo azizwa engazinzile, noma uzizwa sengathi amadolo angase 'aphelelwe amandla' noma aphule.
Izimpawu zokulimala kwe-MCL zivame ukuhambisana nokulimala. Ukulimala kwe-MCL kuvame ukufakwa esikalini sika-I kuya ku-III.
- Ithrekhi ye-MCL ye-Grade I
Lena izinyembezi ezingaphelele ze-MCL. I-tendon isaqhubeka, futhi izimpawu ngokuvamile ziyingcosana. Iziguli ngokuvamile zikhononda ngobuhlungu ngokucindezelwa kwi-MCL futhi zikwazi ukubuyela emdlalweni wayo masinyane. Abagijimi abaningi bangabikho amasonto amabili okudlala. - Ibanga lesibili le-MCL
Ukulimala kweGreyidi II kubhekwa njengezinyembezi ezingaphelele ze-MCL. Lezi ziguli zingase zikhononde ngokungahlali kahle lapho zizama ukusika noma ukugxila. Ubuhlungu nokuvuvukala kubaluleke nakakhulu. Ngokujwayelekile, kuyadingeka isikhathi sokuphumula kwamasonto amathathu kuya kwamane.
- Imisindo ye-MCL yeBanga III
Ukulimala kwebanga lesi-III kuyinkemba ephelele ye-MCL. Iziguli zinebuhlungu obukhulu nokuvuvukala, futhi ngokuvamile kunenkinga yokuguqa ngamadolo. Ukukhubazeka, noma ukuphawula, kuyinto ejwayelekile yokuthola izinyembezi zeBanga III ze-MCL. I-knee brace noma i-knee immobilizer ngokuvamile idinga induduzo, futhi ukuphulukiswa kungathatha amasonto ayishumi kuya kwangu-12.
Okunye okungajwayelekile kwe-ligament ye-collateral ligament yisisignali se-Pellegrini-Stieda, esivame ukubonakala ekulimaweni okungapheli kwe-MCL. Lokhu kungavamile kubonakala kwi-X-ray lapho i-calcium deposits ibonakala ku-MCL. Ngokuvamile, idiphozi ye-calcium ihambisana nokunamathiselwe kwegamentali ekugcineni kwethanga lesenzeni.
Abantu abanezinhlungu kule ndawo ngezinye izikhathi kuthiwa banePellegrini-Stieda syndrome. Ukwelashwa kwalesi simo ngokuvamile kuthatha izinyathelo ezilula, nakuba ezimweni ezingavamile i-deposit calcium ingasuswa.
Ukwelapha
Ukwelashwa kwezinyembezi ze-MCL kuncike ebukhulu bokulimala. Ukwelashwa kuqala njalo ngokuvumela ubuhlungu ukuba buyeke futhi buqale umsebenzi wokuhamba. Kulandelwa ukuqinisa amadolo bese ubuyela ezemidlalo nasemisebenzini. Ukwehla kwegazi kungase kube usizo ekwelapheni ukulimala kwe-MCL. Ngenhlanhla, ngokuvamile ukuhlinzwa akudingeki ukwelashwa kwezinyembezi ze-MCL.
