Anatomy yeDistal Humerus
Iyo distal humerus yakakamurwa kuita yepakati column uye lateral column.
Medial Column
Mutsara wepakati unosanganisira chikamu chemukati metaphysis yehumerus, iyo medial epicondyle, uye medial condyle, kusanganisira iyo trochlea yehumerus.
Lateral Column
Iyo lateral column inosanganisira lateral chikamu che metaphysis yehumerus, iyo lateral epicondyle, uye lateral condyle, kusanganisira capitulum yehumerus.
Coronoid Fossa uye Olecranon Fossa
Iri pakati pemakoramu maviri pane anterior coronoid fossa uye posterior olecranon fossa.

Mechanism yeKukuvadza muDistal Humerus Fractures
Iyo distal humerus yakakamurwa kuita yepakati column uye lateral column.
Sei iyo distal humerus inowanzoita kuputsika?
Sechikamu chakakosha chejoint yegokora, distal humerus fractures inowanzobva kune 'direct trauma' (sekudonha kudonhera pagokora) kana 'indirect trauma' (sekumonyorora kana kukanda zviito).

AO Classification: Yakarurama Typing Kutungamira Kuvhiya Sarudzo
Zvinoenderana neiyo AO classification system, distal humerus fractures yakakamurwa seizvi, ichipesvedzera zvakananga kusarudzwa kwemaitiro ekurapa:
Rudzi rweA: Kuwedzera-articular fractures
- A1: Kutsemuka kuri nyore, hapana kubatanidzwa kwekutaura. - A2 / A3: Yakakanganiswa kana yakadzingwa metaphyseal fractures, kutarisisa kunodiwa kune angular deformities.
Rudzi B: Chikamu che articular fractures
Mutsara wekuputsika unosanganisira nzvimbo yakabatana asi pasina kuparadzaniswa kwakakwana; anatomical kuderedza kunofanirwa kudzoreredza kubatana kwekubatana.
Rudzi C: Yakazara articular fractures
- C1 / C2: Nyore intra-articular fractures ine metaphyseal kubatanidzwa. - C3: Yakagadzirirwa intra-articular fractures, yakanyanya kuoma kurapa; kugadziriswa kwakasimba kunodiwa kuderedza dambudziko rekurwadziwa kwearthritis.. Loc
Kukosha Kwekuronga:
IAO classification inojekesa kuoma kwekuputsika uye inopa hutungamiri hwekusarudzwa kweplate (somuenzaniso, single vs. dual plates, Siruu yekukiya magadzirirwo) kuti ave nechokwadi chekugadzirisa simba uye biological balance.
