Human hannu da dantse har dogon tubular ƙasũsuwa. Kamar biyu daga gare su. A babba hannu ne ulna da radius. Suna mai lankwasa don haka da cewa, kasancewa kusa, da alaka ne kawai a da iyakar. Cikin dukanin ta tsawon kamar yadda akwai wani sarari tsakanin su. Ulna da radius hada jiki (diaphysis) da kuma iyakar (epiphyses). A epiphysis ne hadin gwiwa saman.

Ta hanyar daya daga cikin articular saman ne da za'ayi tare da wani fili daga cikin humerus. Wasu kuma suna tsara za a guda biyu tare da wani wuyan hannu segments.

Ulna da radius tare da tsawon da triangular siffar. Akwai uku gefuna da uku saman. Daya surface ne directed gaba, da kuma na biyu - da baya. The uku - da ulna - a cikin gida, yayin da katako - waje.

Na uku gefuna da kaifi daya. Yana rarrabe gaba da raya saman ta da m kashi, iyakance sarari tsakanin ƙasũsuwa. A wannan batun, shi yana da wani sunan - da interosseous baki.

Ya kamata a lura cewa bangaren sassan kwarangwal na hannu da dantse, kuma da na kowa siffofin, akwai kuma siffofi.

Saboda haka, radius aka located a kan m gefen hannu da dantse. Ƙananan epiphysis wannan sashi shi ne mafi m. A saman karshen ne a kashi shugaban. A da shi akwai kananan ciki. shugaban baki ne hadin gwiwa karkara.

Kawai a kasa da kai ne wuyansa. A radius ne ma aka bai da wani musamman tuberosity - da abin da aka makala na biceps tsokoki na kafada.

A radius bambanta da ɗan kumbura ƙananan karshen. A ciki gefen located fillet. Ya zo a cikin ulna.

A gefen akwai styloid aiwatar da mikawa zuwa ƙasa. A kasa surface yana da wani concave carpal articular surface. Ta wajen da protrusion ne zuwa kashi rabo biyu ga lunate kuma da navicular kashi.

A yi, akwai da dama daga rauni lalace hannu da dantse. Daga cikin wadannan masana ware fiye ko ƙasa da na kowa. Saboda haka, a sakamakon da line (fil hannu da dantse) ko kai tsaye ba (da hannu drop) rauni na iya faruwa a duka diaphyseal karaya da ƙashi na daga hannu da dantse. Wannan samar karami, niƙaƙƙun gaɓãɓuwa segments, da matsayin wanda zai iya bambanta. Saboda da rage daga cikin membrane, located tsakanin kasũsuwa, ashe, da, niƙaƙƙun gaɓãɓuwa ayan kusanci juna.

Karaya na radius biya diyya halin da rage na hannu da dantse. A haƙuri kula da kyau hannu ji rauni reshe. Motsi da wani ɓaɓɓake tsokani kaifi zafi a lokacin da yake bincike rabo gefen m daga matsawa sarari na hannu da dantse rabo rauni, kuma a karkashin wani axial load.

Fadowa a kan wani mara tausayi yakan kishi hannu, kamar yadda mai mulkin, akwai wani karaya da radial kai. A wannan yanayin, a yankin na gwiwar hannu akwai zafi, akwai aka busa, da mãsu haƙuri ne wuya don matsawa da reshe. Saboda a gaskiya wannan irin lalacewar hada da dama iri, don kafa wani cikakken ganewar asali, shi wajibi ne su gudanar da X-ray jarrabawa.
