Yintoni i-acromioclavicular joint dislocation?

Ukuqhekeka kwamalungu e-Acromioclavicular kubhekisa kuhlobo lokulimala kwegxalaba apho i-acromioclavicular ligament yonakele khona, nto leyo ebangela ukuqhekeka kwe-clavicle. Kukuqhekeka kwamalungu e-acromioclavicular okubangelwa ngamandla angaphandle asetyenziswa kwisiphelo se-acromion, nto leyo ebangela ukuba i-scapula iye phambili okanye ezantsi (okanye ngasemva). Apha ngezantsi, siza kufunda ngeentlobo kunye nonyango lokuqhekeka kwamalungu e-acromioclavicular.

Ukuqhekeka kwamalungu e-acromioclavicular (okanye ukwahlulwa, ukwenzakala) kuxhaphake kakhulu kubantu ababandakanyeka kwimidlalo nomsebenzi womzimba. Ukuqhekeka kwamalungu e-acromioclavicular kukwahlukana kwe-clavicle kwi-scapula, kwaye uphawu oluqhelekileyo lwale ngozi kukuwa apho indawo ephezulu yegxalaba ibetha emhlabeni okanye impembelelo ngqo yendawo ephezulu yegxalaba. Ukuqhekeka kwamalungu e-acromioclavicular kudla ngokuvela kubadlali bebhola ekhatywayo kunye nabakhweli beebhayisekile okanye abakhweli beebhayisekile emva kokuwa.

Iintlobo zokususwa kwamalungu e-acromioclavicular

II°(udidi): ijoyinti ye-acromioclavicular isuswa kancinci kwaye i-acromioclavicular ligament inokolulwa okanye ikrazuke kancinci; olu lolona hlobo luqhelekileyo lokulimala kwejoyinti ye-acromioclavicular.

II° (udidi): ukukhubeka okuncinci kwelungu le-acromioclavicular, ukufuduka kusenokungabonakali xa kuhlolwa. Ukukrazuka ngokupheleleyo kwelungu le-acromioclavicular, akukho kuqhawuka kwelungu le-rostral clavicular ligament

III° (udidi): ukwahlulwa ngokupheleleyo kwejoyinti ye-acromioclavicular ngokukrazuka ngokupheleleyo kwejoyinti ye-acromioclavicular, i-rostroclavicular ligament kunye ne-acromioclavicular capsule. Njengoko kungekho ligament yokuxhasa okanye yokutsala, ijoyinti yegxalaba iyagoba ngenxa yobunzima bengalo engasentla, ngoko ke i-clavicle ibonakala icacile kwaye ijonge phezulu, kwaye ukubonakala kwayo kunokubonakala egxalaba.

Ubunzima bokuqhekeka kwamalungu e-acromioclavicular bunokwahlulwahlulwa lube ziintlobo ezintandathu, apho iintlobo I-III ziyeyona ixhaphakileyo kwaye iintlobo IV-VI zinqabile. Ngenxa yomonakalo omkhulu kwimisipha exhasa ummandla we-acromioclavicular, zonke iintlobo zokulimala kohlobo III-VI zifuna unyango lotyando.

Iphathwa njani i-acromioclavicular dislocation?

Kwizigulane ezine-acromioclavicular joint dislocation, unyango olufanelekileyo lukhethwa ngokwemeko. Kwizigulane ezinezifo ezincinci, unyango oluzinzileyo lunokwenzeka. Ngokukodwa, kwi-type I acromioclavicular joint dislocation, ukuphumla kunye nokuxhonywa ngethawula eliyinxantathu kangangeveki e-1 ukuya kwezi-2 kwanele; kwi-type II dislocation, intambo engasemva ingasetyenziselwa ukuthintela ukuhamba. Unyango oluzinzileyo olufana nokubopha igxalaba kunye nengqiniba kunye nokuqhobosheka; izigulane ezinemeko embi kakhulu, oko kukuthi, izigulane ezine-type III yokwenzakala, kuba i-joint capsule yazo kunye ne-acromioclavicular ligament kunye ne-rostral clavicular ligament ziqhekekile, nto leyo eyenza ukuba i-acromioclavicular joint ingazinzi ngokupheleleyo kufuneka icinge ngonyango lotyando.

Unyango lotyando lunokwahlulwahlulwa lube ziindidi ezine: (1) ukufakwa kwangaphakathi kwejoyinti ye-acromioclavicular; (5) ukufakwa kwe-rostral lock kunye nokwakhiwa kwakhona kwe-ligament; (3) ukususwa kwe-distal clavicle; kunye (4) ukuguqulwa kwemisipha yamandla.
