Humerus

Nā iwi o ka'ūhā mua kaei - he paa kumu no na mea he nui nāʻiʻo, tendons a me ligaments. O i ike ole ia e ka luna, a malalo lala - he kanaka ana, ke hiki, e hana nāʻano likeʻole o ka hana. I na mea kaua, o ka loa a me ka holomua iaea ooieoeiiaeuiiai, e pono loa i ka hoʻokolokolo pono iwi kumu a me ka ikaika ami.

Nature Ua hoakaka ia na mea a pau i loko o ke kanaka, no laila, i ka luna poʻohiwi kaei ninoieo o ka scapula, clavicle, humerus, ulna a me ke kahahńnai, e like me na iwi uuku o ka palaki. Alaila, e haka pono mau hoʻokumu paʻaʻana i nā mea a pau o ka iwi nāʻiʻo, no laila, i ka lima i hiki ke neʻe.

Humerus - kekahi o ka mea nui a me ka loa papakaukau iwi i loko o ka kanaka kino. Ua ninoieo o ka diaphysis a omo iwi o ke kino a me nā epiphysis, i mea ami surfaces.

Ināʻalo me ia i ka'anatomia o ka hoʻonaʻauao 'ana, ke pehea he functionally manaʻo i kēia iwi e ike.

E like me ka kekahi luna, mai ka humerus mai i kona poʻo - kaʻoki lāʻau lapaʻau ai, keia mea ma ka iwi, mai hemo mai ia oi pinepine. Eia naʻe, muscular maoli ua papahana i loko o ia i kekahi ala e, inā e hana i kēia mea ma ka loa, pili Muscle nuipa a piʻi pū, ma laila ka pale 'ana i ka iwi.

Eia hou, i ka humerus loaʻa paha kekahi mau protrusions, a bumps, e i i i pili i ka nui nāʻiʻo o ka poohiwi. Mai na nā wānana waiwai hohola aku kualono a me kuahiwi, ma waena o a ka intertubercular Groove - ma keia wahi, he mea ka IeIIeYOA o ka tendon o na biceps.

I ka lalo epiphysis i mau condyle, a ma luna o ia mau epicondyle - Ua hoi heʻano o pokou tubercles, a he hapa o ke kuʻekuʻe aku ami. Eia, he mau lua - ulnar, a me ka pāpale aliʻi, ka mea e pono ai no ka oi anuanu kŰia keʻano o ka hanaʻana o ka ulna a me ke kahahńnai o.

Humerus - heʻano huikau 'ole, a ma ka hou ana i ka papa kākoʻo, e hana nō hoʻi i ka helu o ka' ē aʻe. No ka laʻana, hematopoietic. E like me oe i ike, o ka mea a pau iwi lōʻihi i nā loko i paka ulaula koko keena. Ke cancellous iwi mea ula iwi ka lolo, ka mea i hanaʻia i kēia kuleana pili i.

Eia hou kekahi, cancellous iwi mea hiki ke paka kumumea i aloha ia i ka'ōnaehana paleʻea'ōnaehana a me ke koko clotting.

It E e hoʻomaopopo i ka nui a me ke anawaena o ka iwi ma kēlā me kēia kanaka pākahi. Kēia hilinaʻi nui ma luna o ke kiekie, ka helu o ka hoʻopā ai a me ka māhuaola mai ka hereditary predisposition. Pinepineʻalo me ke kulana home 'ole kahi e hoʻomanawanui iki mai i ka mahuahua fragility a me ka brittleness o ka iwi aie i ka kalipuna deficiency a me nā micronutrients. Kēia kaʻina hana hiki ke hana a hiki i ka utero.

poʻohiwi fractures pinepine ana i loko o opiopio kula-makahiki keiki, a me nā kūpuna. Keia mea aie a hiki i ka aoao o ke ola i loko o ka mua, a me ka emi ma physiological ikaika i loko o ka lua o ka hihia.

Humerus fracture collapses ma ka nawaliwali wahi - i loko o ka mahinaʻai o keʻoki lāʻau lapaʻau ai, akā, ma laila nō nā koho no fractures. Children - subperiosteal fracture o ke 'ano "'ōmaʻomaʻo lala", a me nā mākua hoʻoneʻe fractures.

Ma kekahi o kēia mau wahi, i hiki, i ka hoʻomanawanui pono mālama.

mau ano hiki ke hana osteosynthesis o ka humerus. Aia He He kūikawā Ilizarov i hoʻomākaukauʻia, aʻo ka mea e hiki ai e hoʻopaʻa i ka wepa i ka na hakina. I ka hoike ana o na huila hiki ke lawe mai loa ma kekahi pae, a kokoke i na ami. Ke ka manaʻo pohihihi o ka hoʻokomo 'ia' ana o nā huila ma ke keena kolu o ka'ūhā mua ma luna o ka pāʻili (i loko o ka axillary māhele'āina) me ka mea, e lawe discomfort a me ka hana a he leo no ka hoomanawanui, no laila, na paipu i hookomo i loko o ka mahinaʻai o X-hoʻokino.

I mea e ka hapanui pololei hui pu iho i ka hakina, e mea hiki ke hoʻohana i ke ano o skeletal traction ma mua ma luna o ka noonoo o kanaka.

Trauma pinepine hoʻohana kūikawā papa a me nā kui nao no ka fixation o ka humerus, ina he lesion mea,ʻaʻole he nui, a me ka helu o nā koena mea i oi aku 3-4 apana.
