Ihumerus

Amathambo umbhinqo zamagxa - isiseko esiluqilima izihlunu ezininzi, imisipha kunye nemisipha. Yinto akukho mfihlelo kwesebe ephezulu nesezantsi - intshukumo yabantu, ukukwazi ukwenza iintlobo ezahlukeneyo umsebenzi. Ukuze ezandla eliphezulu kakhulu kwaye esebenza, kufuneka kakhulu isiseko ithambo olunzulu kunye iijoyinti.

Nature linike into umntu, ngoko ephezulu emagxeni umbhinqo iqulathe scapula, clavicle, ihumerus, ulna kunye radius, kwakunye amathambo encinane brush. Ngako oko, zonke ezi kwiziseko izihlunu ithambo ayinakutshintshwa, ukuba isandla olukwazi intshukumo.

Ihumerus - enye amathambo sikhulu kakhulu enkulu emzimbeni womntu. Siqulathe diaphysis okanye tubular amathambo lomzimba epiphysis ezimbini, ezo iindawo ezimanyeneyo.

Ukuba senze anatomy enjalo wemfundo, sinokubona indlela ezisebenza ndacinga le ithambo.

Njengokuba kunjalo nawuphi na umgangatho, ukusuka ihumerus inendawo ebomvu obuthathaka - entanyeni ngotyando, oku kulapho ithambo uyazifohloza phantsi rhoqo. Noko ke, isakhelo dystrophy yenzelwe ngendlela yokuba xa usebenzisa lo apho ukunyuka izihlunu ubunzima kakhulu kakhulu, ngaloo ndlela ukukhusela ithambo.

Ukongeza, le ihumerus uye lunamaqoqo eziliqela, okanye amaqhuma, ukuba ezo izihlunu likhulu emagxeni eqhotyoshelweyo. Ukususela uqikelelo yandisa nasentshonalanga okanye incopho, phakathi apho emseleni intertubercular - kule ndawo apho kuthinjwe imicu ye zomfana.

Xa epiphysis zikhabane condyle ezimbini, ngaphezu kwabo epicondyle ezimbini - naye uhlobo tubercles nokudleka, nto leyo eyinxalenye ye entlanganweni ingqiniba. Apha kukho kwemingxuma emibini - ulnar kunye sithsaba, ukuba kuyimfuneko zeenkqubo yemephu yehlathi nangaphezulu ulna kunye radius.

Ihumerus - isakhiwo kunokuba inzima, yaye ukongeza umsebenzi inkxaso uya kwenza kwakhona iqela kwabanye. Ngokomzekelo, hematopoietic. Njengoko usazi, onke amathambo elide izikhungo ezivelisa iiseli ezibomvu zegazi. Ithambo cancellous yi lomongo wethambo ebomvu, owenza lo msebenzi.

Ukongeza, ithambo cancellous unako ukuvelisa izinto ezichaphazela amajoni omzimba kunye ekunqandeni negazi.

Kufuneka kuqatshelwe ukuba ubukhulu kunye sangqa wethambo kwi umntu ngamnye. Oku kuxhomekeke ephakamileyo, inani engenayo kunye nezakhi sifuze amafa. senze amaninzi nemeko apho izigulane babe ubu ukwanda kunye brittleness amathambo ngenxa calcium ukushiyeka kunye nezinye Izakha. Le nkqubo abunjwe nkqu Esibelekweni.

Ukophuka igxalaba akholisa ukubakho yabantwana abakwiminyaka yokuba sesikolweni ulutsha nabantu abadala. Oku kubangelwa yindlela ubomi ethambisayo ukuhla amandla komzimba kwimeko yesibini.

Ihumerus ukwa ehlala kwindawo olubuthathaka kakhulu - entsimini entanyeni ngotyando, kodwa zikhona ezinye iindlela ze waphuka. Abantwana - ukwa subperiosteal lohlobo "amasebe green", kunye abadala abangenayo waphuka.

Kuyo nayiphi na yezi meko, isigulane sidinga inkathalo.

zingenziwa iindlela eziliqela osteosynthesis le ihumerus. Kukho ekhethekileyo isixhobo Ilizarov, nto leyo eyenza kube lula ukuba kutywinwe amaqhekeza ezikhoyo. Ukuqaliswa iiasi ekuLunyukisiweyo ngazo zinakho ukuqhutywa ngokupheleleyo kulo naliphi na inqanaba kunye kufuphi amalungu. Xaka le ukuqaliswa iiasi kwi wesithathu eliphezulu igxalaba phezu yangaphakathi (kwingingqi axillary) njengoko kusenza ubuhlungu nokuhlukunyezwa kwisigulana, ngoko iinaliti zifakiwe entsimini X-ezimile.

Ukuze ukudibanisa kakhulu nangokuchanekileyo amaqhekeza, kunokwenzeka ukuba usebenzise indlela imoto skeletal phambi walathisa ifowuni.

Trauma basoloko amacwecwe ezizodwa ngezikhonkwane kuba nenkanuko yalo ihumerus, ukuba sisilonda esidumbileyoesingaphakathi ayikho likhulu kakhulu kwaye inani ngamaqhekeza ayikho iziqwenga ngaphezu 3-4.
