Ukungazenzeki kwe-postonolateral kwenzeka lapho kunomonakalo ezakhiweni ezisekela ngaphandle kwehlangothini lamadolo, ikhonteli le-posterolateral. Lezi zakhiwo zibalulekile ekuvimbeleni izimpawu zokungazinzi kwamadolo . Uma iziguli zilimaza amagciwane, kungenzeka ukulimaza izakhiwo zekhoneni le-posterolateral.
Kuze kube maduzane, kwakungekho ukunakwa okuningi okukhokhelwe izakhiwo zekhoneni le-posterolateral.
Lezi zakhiwo zihlanganisa i -ligal lateral , i-popliteus tendon, ne-knee joint capsule. Ubufakazi bamuva buveze ukuthi lezi zakhiwo zingalimala lapho amadolo eqinisa umonakalo wegamentli kuhlanganise nezinyembezi ze-ACL nezinyembezi ze- PCL . Uma izakhiwo zekhoneni le-posterolateral zingahlolwa futhi zonakaliswe, izinkinga eziqhubekayo zamadolo zingenzeka naphezu kokwelashwa kwamanye amadolo.
Izimpawu zokulimala kwe-Posterolateral Corner
Ukulimala ekhoneni le-posterolateral kuvame ukuqhutshwa kanye nokulimala emigqumeni ebaluleke kakhulu, i-ACL, ne-PCL. Ukulimala kwamakhonkoni ama-postolateral ngokuvamile kwenzeka ngezingcingo zokuguqa . Amaphesenti angaba ngu-70 e-posterolateral ekhunjulwa okwenzeka ekubekeni kokulimala ku-ACL kanye / noma i-PCL. Ezinganeni ezingaba ngu-20-30%, kukhona ukulimala okukude ekona elingemva kwe-posterolateral.
Izimpawu zokulimala kwamakhonksi emva kokuqala kuhlanganisa ukuzwa ukuthi idolo lizokhipha.
Ubuhlungu nokuvuvukala kungaphezu kwehlangothini lamadolo, ngaphezulu ngasekupheleni kwamadolo. Amaphesenti angu-15% asekela ukulimala ekhoneni le-posterolateral futhi izolimaza i-peroneal nererve, i-nerve ebalulekile engabangela ukuphazamisa phansi komlenze nonyawo.
Lapho uhlola idolo lakho ngokungazenzeki kwe-posterolateral rotatory, uvivinyo olubucayi luyaziwa ngokuthi yi-Dial Test.
Udokotela wakho uzokunquma ukujikeleza kwamadolo (ngokuphendulela unyawo ngaphandle) bese uqhathanisa lokhu namadolo ahlukile. Uma kukhona ukushintshaniswa ngokweqile, lokhu kuyinkomba yokulimala ekona lokuhamba phambili. Ngokuhlola izinga lokujikeleza emazingeni ahlukene okuguquka kwamadolo, udokotela wakho anganquma ukuthi yiziphi izakhiwo ezingalimala.
Ukwelapha
Ukunakekelwa kwekhoneni le-posterolateral kuncike ekungenikeni kokungazinzi. Isizathu esiyinhloko sokuthi ikhonteli le-posterolateral libe yinto ethakazelisayo emathambo wezinzwa ukuthi ukuthi kucatshangelwe ukuthi kungani abantu abaningi abahluleka ukuhlinzwa ukulungiswa kwe-ACL, kungenzeka ukuthi babengazi kahle ukulimala kwamakhonksi e-posterolateral.
Lapho ukulimala kwamakhonksi e-posterolateral kubangele ukungabi nakhubazeka okukhulu emadolweni, izinhlaka zilungiswa ngokuhlinzwa. Lokhu kudinga ukugoqa ngaphandle kwehlangothini lamadolo. Ukulimala kwakamuva kungakalungiswa, kanti ukulimala okungapheli kungahle kudingeke ukuthi kusetshenziswe izicubu zokunikela ukuze kuvuselelwe izakhiwo ezimele. Ukulimala kakhudlwana ngokuvamile kudinga ezinye izicubu zokunikela ukuze zithuthukise ukulungiswa ngaphandle kwamadolo.
Rehab Ngemuva kokuhlinzwa
Ukuvuselelwa emva kokuvuselelwa kwe-posterolateral kuzoxhomeka ezakhiweni ezilungiswe emadolweni.
I-Rehab ifana nokubuyiswa kwamanye ama-knee ligament, kodwa kufanele uxoxe ngokuhlukahluka okwenziwe nodokotela wakho ohlinzayo.
