Dzanja olowa: wakudziko ndi kudwala

Dzanja olowa ndi chimodzi chigawo cha burashi zovuta olowa. Iwo dvuhostny limodzi ndi mawonekedwe a kali articular - ellipsoid. Movement n'zotheka mu ndege sagittal, mwachitsanzo flexion ndipo powunikiridwa m'chiphiphiritso, mu ndege mazunzo - atigwira ndi adduction, zozungulira.

The dzanja olowa chikuphatikizapo lonse zitani kapisozi, m'mphepete chapamwamba chimene Ufumuyo kwa fupa zozungulira , ndi chimbale articular, ndi pansi - kwa kali articular za mzere woyamba mafupa carpal. Kapisozi kuchokera kumbali zonse analimbitsa Mitsemphayi.

Ziyerekezo kudula dzanja olowa ndi arcuate mzere kulumikiza ulnar styloid ndondomeko ndi utali wozungulira.

Pa palmar pamwamba pa dzanja olowa synovial kumaliseche ali awiri tendons flexor zala pa iwo kwambiri padziko-ili mtolo flexor retinaculum. Mbali ina ali extensor tendons unazunguliridwa mu m'chimake asanu synovial, komanso ali kwambiri padziko extensor retinaculum.

Dzanja olowa ndi anatomical mtunda odziwika. Zikuphatikizapo: mutu wa ulna ndi, tubercle wa Lister (ili pa utali wozungulira wa), ndi styloid ndondomeko mafupa awiri, pisiform fupa "anatomic" snuffbox mu gawo proximal limene lili styloid ndondomeko ya utali wozungulira wa, grooves olowa (proximal, wapotalikira ndi kumbuyo).

njira zosiyanasiyana angasinthe yachibadwa anatomical ubale wa mbali olowa. phunziro ayenera kulabadira awo ndi mkhalidwe wa khungu: mtundu ndi kuteteza chithunzi ake, ndi pa kuteteza thupi olowa kukula, kasinthidwe, pa chikhalidwe cha kale zikhomo anatomical ndi topographic. Zingakhalenso kwambiri kuuza boma la palmar fascia, tendons, dzanja ndi forearm minofu. Pa nthawi yomweyo m'pofunika kufufuza onse olowa ndi.

Nthawi zambiri pali kudwala monga hygroma wa dzanja, amene ndi maphunziro chotupa kistoobraznym.

Monga izo zikuwoneka? maphunziro imapanga khungu m'goli kutupa awiri amene angafikire zamitundu lalikulu kwambiri - ndi masentimita angapo. Kabukuka kali ndi misa odzola ngati a hygroma, kamene kamayambitsa kupweteka kwambiri pamene anakhudza. Hygroma aumbike ku yokha olowa. zinthu kukulitsa akhoza kupanga zifukwa zosiyanasiyana: wolimba zolimbitsa thupi, kuvulala ndi zina zotero. Hygroma umatchulidwatchulidwa kumbali m'mbuyo, angaoneke pa minofu chala flexor ndi mfundo padziko mkati mwa burashi lapansi. Hygroma amasokoneza kugwira ntchito za masiku onse olowa, kuchititsa ululu, choncho amafunika chithandizo. The njira yabwino kwambiri ndi opaleshoni.

wovulala dzanja nthawi zambiri ukapezeka kudzera chosasamala. Ambiri ndi wovulala fupa zozungulira kumapeto ake wapotalikira, lomwe limatchedwanso Colles wovulala. Kumachitika pamene kugwa pa dzanja lotambasula, kujambula pa dzanja, ndi ambiri mwa akazi mu ukalamba.

Wovulala mankhwala ikuchitika monga muyezo: kapena chikhalidwe ndiwofatsa - ndi imposition wa gypsum, kapena ntchito - ntchito metalosteosynthesis.

Ngati inu mulibe thandizo yake yake angathe contractures limodzi lomwe chifukwa malire wotsatira wa zoyenda ya olowa, kugwirizana ndi kusintha chilonda mu kapisozi limodzi tendons ndi minofu, komanso kupweteka kwambiri. Choncho, kuvulala aliyense ayenera kulandira chithandizo mwamsanga. Panthawi yake konzanso kupewa mavuto.
