Humerus

Mafupa a lamba phewa - maziko olimba a minofu ambiri, tendons ndi Mitsemphayi. Ndi palibe chinsinsi chimene chapamwamba ndipo m'munsi nthambi - gulu anthu, luso kuchita mitundu yosiyanasiyana ya ntchito. Kuti manja anali zotsogola ndi zinchito, muyenera ndithu mokwanira fupa m'munsi ndi mafupa amphamvu.

Nature watipatsa chilichonse mwa munthu, kotero chapamwamba phewa lamba tichipeza scapula ndi, clavicle, humerus, ulna ndi utali wozungulira, komanso mafupa ka burashi lapansi. Choncho, ndizosowa onsewa minofu fupa ndi mapulani kuti dzanja amatha kuyenda.

Humerus - imodzi yaikulu komanso chachikulu mafupa mu thupi la munthu. Amakhala ndi diaphysis kapena tubular mafupa a thupi ndi awiri epiphysis, amene ali olowa pamalo.

Ngati anakumana ndi thunthu ngati wa maphunziro, ife tikhoza kuwona momwe zimagwirira ntchito ndinaganiza fupa izi.

Mofanana ndi pamwamba aliyense, kuchokera humerus ali ndi malo ofooka - khosi opaleshoni n'kumene fupa imaphwanya zambiri. Komabe, chimango akulu lakonzedwa mu njira yakuti ngati muzichita izi pamene kwambiri kwambiri minofu misa ukuwonjezeka, potero kuteteza fupa.

Komanso, humerus ali protrusions angapo, kapena tokhala, amene amagwira minofu waukulu wa paphewa. Kuyambira zolosera za kuwonjezera zitunda kapena nsonga, pakati limene poyambira intertubercular - mu malo awa pali ubwenzi wa tendon wa kukongola kwa.

Mu epiphysis m'munsi awiri condyle, ndipo pamwamba pawo awiri epicondyle - ndi mtundu wa timabamputimabampu Bony, zomwe zili mbali ya chigongono olowa. Apa pali maenje awiri - ulnar ndi korona, n'zofunika kwa njira zambiri wandiweyani sanjira wa ulna ndi utali wozungulira.

Humerus - dongosolo m'malo zovuta, ndipo kuwonjezera ntchito thandizo adzachita komanso anthu ena. Mwachitsanzo, hematopoietic. Monga mukudziwa, onse mafupa yaitali ali ziwalo kuti Maselo ofiira a magazi. Fupa cancellous ndi wofiira mafupa, amene amagwira ntchito imeneyi.

Komanso, cancellous fupa ndi kupereka zifukwa zimene zimakhudza chitetezo cha m'thupi ndi magazi clotting.

Tikumbukenso kuti kukula ndi awiri a mafupa pa munthu aliyense payekha. Izi zimadalira kutalika, chiwerengero cha ukubwera ndi zakudya kuchokera kutengera za kumtundu. Nthawi zambiri anakumana ndi vuto kumene odwala ndi fragility chinawonjezeka ndi brittleness mafupa chifukwa chakuchepa kashiamu ndi micronutrients ena. Zimenezi akhoza kupangidwa ngakhale utero.

phewa fractures amayambira ana sukulu komanso okalamba. Ichi ndi chifukwa njira ya moyo wakale ndi kuchepa mphamvu thupi mu nkhani yachiwiri.

Humerus wovulala n'kugwa pa mfundo anafooka - m'munda wa khosi opaleshoni, koma pali zina zimene mungachite kuti fractures. Ana - subperiosteal wovulala mtundu "nthambi wobiriwira", ndi akulu amene anathawira fractures.

Mu aliyense wa awa, wodwalayo amafunika chisamaliro.

njira zingapo angathe kuchitidwa osteosynthesis wa humerus lapansi. Pali wapadera Ilizarov zida, zomwe zimathandiza kuti asindikize makombo alipo. Mawu oyamba a masipoko akhoza ikuchitika kwathunthu pa mlingo uliwonse ndi pafupi malo. Kuvuta ndi kumayambiriro masipoko wachitatu chapamwamba phewa padziko wamkati (m'dera axillary) monga umabweretsa ululu komanso mavuto kwa wodwalayo, kotero masingano ndi anaikapo m'munda wa X woboola pakati.

Pofuna molondola kwambiri kuphatikiza makombo, n'zotheka ntchito njira samatha chigoba pamaso kutsogolera chipangizo.

Vutoli zambiri ntchito mbale wapadera ndi zomangira kwa fixation wa humerus, ngati ndi chotupa ndi aakulu kwambiri ndipo chiwerengero cha zidutswa si ndalama kuposa 3-4.
