Dzanja lanu limapangidwa ndi mafupa ang'onoang'ono ndi zimfundo zomwe zimalola dzanja lanu kuyenda m'njira zingapo. Zimaphatikizaponso kutha kwa mafupa amikono.

Tiyeni tiwone bwinobwino.

Mafupa a Carpal m'manja

Dzanja lanu limapangidwa ndi mafupa ang'onoang'ono asanu ndi atatu otchedwa carpal bones, kapena carpus. Awa amalumikiza dzanja lanu ndi mafupa awiri atalire kunkhongo kwanu - utali wozungulira ndi ulna.

Mafupa a carpal ndi mafupa ang'onoang'ono, ovunda, ndi amakona atatu. Gulu la mafupa a carpal m'manja limapangitsa kuti likhale lolimba komanso losinthika. Dzanja lanu ndi dzanja lanu sizingagwire ntchito chimodzimodzi ngati cholumikizira chamanja chikangokhala ndi fupa limodzi kapena awiri akulu.

Mafupa asanu ndi atatu a carpal ndi awa:

• Scaphoid: fupa lalitali loboola bwato pansi pa chala chanu
• Zamalonda: fupa lokhala ngati kachigawo pambali pa scaphoid
• Trapezium: fupa lokhala ndi mabwalo ozungulira pamwamba pa scaphoid ndi pansi pa chala chachikulu
• Zamgululi fupa pambali pa trapezium yomwe imawoneka ngati mphero
• Sungani: fupa lozungulira kapena loboola pakati pakati pa dzanja
• Chidwi: fupa pansi pa dzanja la pinki la dzanja
• Gawo lachitatu: fupa lopangidwa ndi piramidi pansi pa hamate
• Pisiform: fupa laling'ono, lozungulira lomwe limakhala pamwamba pa katatu

Anatomy yolumikizana ndi dzanja

Dzanja lili ndi mfundo zitatu zazikulu. Izi zimapangitsa kuti dzanja likhale lolimba kuposa ngati linali ndi cholumikizira chimodzi chokha. Imaperekanso dzanja lanu ndikukuyendetsani mayendedwe osiyanasiyana.

Malumikizidwe amanja amalola dzanja lanu kusunthira dzanja lanu mmwamba ndi pansi, monga mukakweza dzanja lanu kuti liweyule. Zilumikizazi zimakulolani kupindika dzanja lanu kutsogolo ndi kumbuyo, mbali ndi mbali, ndikusinthasintha dzanja lanu.

Mgwirizano wa Radiocarpal

Apa ndipomwe utali wozungulira - fupa lakumbuyo lakumaso - limalumikizana ndi mzere wapansi wamafupa amanja: mafupa a scaphoid, lunate ndi triquetrum. Cholumikizira ichi chimakhala pambali ya chala chanu chamanja.

Mgwirizano wa Ulnocarpal

Uku ndikulumikizana pakati pa ulna - fupa lakumbuyo lakutsogolo - ndi mafupa amanja am'miyendo yamiyendo. Ili ndiye mbali yakumanja ya pinki ya dzanja lanu.

Mgwirizano wapakati wa radioulnar

Ophatikizanawa ali m'manja koma samaphatikizapo mafupa a dzanja. Amalumikiza kumapeto kwenikweni kwa utali wozungulira ndi ulna.

Mafupa amanja olumikizidwa ndi zimfundo za dzanja

Mafupa a manja pakati pa zala zanu ndi dzanja lanu amapangidwa ndi mafupa asanu ataliatali otchedwa metacarpals. Amapanga mafupa kumbuyo kwa dzanja lanu.

Mafupa a dzanja lanu amalumikizana ndi mafupa anayi apamwamba:

• trapezium
• trapezoid
• sungani
• hamate

Komwe amalumikizana amatchedwa ma carpometacarpal joints.

Minofu yofewa m'manja

Pamodzi ndi mitsempha yamagazi, misempha, ndi khungu, minofu yofewa yayikulu m'manja imaphatikizapo:

• Ziphuphu. Mitsempha yolumikiza imagwirizanitsa mafupa a mkono wina ndi mzake komanso kwa dzanja ndi mkono wamtsogolo. Magalaketi ali ngati zotanuka zomwe zimasunga mafupa. Amadutsa dzanja kuchokera mbali zonse kuti agwirizane mafupa.
• Zowonjezera Tendons ndi mtundu wina wamtundu wolumikizana womwe umamangiriza minofu ndi mafupa. Izi zimakuthandizani kusuntha dzanja lanu ndi mafupa ena.
• Bursae. Mafupa amanja azungulidwanso ndimatumba odzaza madzi otchedwa bursae. Matumba ofewawa amachepetsa mkangano pakati pa tendon ndi mafupa.

Kuvulala kwamanja kwanthawi zonse

Mafupa, dzanja, minyewa, minyewa, minofu ndi minyewa zitha kuvulala kapena kuwonongeka. Kuvulala kwamanja pamikhalidwe ndi monga:

Sprain

Mutha kupukusa dzanja lanu politambasula kwambiri kapena kunyamula china cholemera. Kutupa kumachitika pakakhala kuwonongeka kwa mitsempha.

Malo ofala kwambiri opindika pamanja ndi olumikizana ndi ulnocarpal - cholumikizira pakati pa fupa lamanja ndi fupa lamanja padzanja lamanja la pinky.

Impaction matenda

Amatchedwanso ulnocarpal abutment, mawonekedwe a dzanja lamtunduwu amachitika pamene fupa la mkono wa ulna limakhala lalitali pang'ono kuposa utali wozungulira. Izi zimapangitsa kulumikizana kwa ulnocarpal pakati pa fupa lino ndi mafupa anu amanja kukhala osakhazikika.

Impaction syndrome imatha kubweretsa kulumikizana pakati pa ulna ndi mafupa a carpal, zomwe zimabweretsa zowawa komanso kufooka.

Kupweteka kwa nyamakazi

Mutha kumva kupweteka kwam'mimba pamatenda am'mimba. Izi zitha kuchitika pakutha kokhazikika kapena kuvulala m'manja. Muthanso kupeza nyamakazi yamatenda amthupi chifukwa cha kusamvana kwamthupi. Matenda a nyamakazi amatha kuchitika kulikonse.

Kuphulika

Mutha kuthyola fupa lililonse m'manja mwanu kuchokera kugwa kapena kuvulala kwina. Mtundu wambiri wothyoka m'manja ndi kuphulika kwa utali wotalika.

Kuphulika kwa scaphoid ndiye fupa la carpal lomwe limasweka kwambiri. Ili ndiye fupa lalikulu pambali ya chala chanu chamanja. Itha kuthyoka mukamayesera kuti mugwere kapena kugundana ndi dzanja lotambasula.

Kuvulala mobwerezabwereza

Zovulala zodziwika pamanja zimachitika chifukwa choyenda mofanana ndi manja anu ndi manja anu mobwerezabwereza kwa nthawi yayitali. Izi zikuphatikizapo kulemba, kulemba mameseji, kulemba, ndi kusewera tenisi.

Zitha kupangitsa kutupa, dzanzi, ndi kupweteka m'manja ndi dzanja.

Kuvulala kwamavuto kumatha kukhudza mafupa, mitsempha, ndi mitsempha ya dzanja. Zikuphatikizapo:

• ngalande ya carpal
• ziphuphu zamagulu
• tendinitis

Kutengera kuvulala, kutuluka, komanso momwe zinthu zilili payekha, chithandizo chamankhwala wamba pamanja chimachokera pakupuma, kuthandizira, ndi zolimbitsa thupi mpaka mankhwala ndi opaleshoni.

Mwachitsanzo, carpal tunnel ili ndi machitidwe ake ndi zida zake zomwe zitha kuthandiza. Matenda a nyamakazi adzakhala ndi njira yake yothandizira, nayenso. Onetsetsani kuti mwalankhula ndi omwe amakuthandizani ngati muli ndi nkhawa zamanja anu.
