Chii chinonzi metacarpal fracture?

Nhanganyaya

Metacarpal fracture kukuvara kwemaoko kunowanzoitika kunobata mapfupa marefu ari muruoko. Kuongororwa kwakakodzera uye kurapwa zvakakosha kudzivirira matambudziko akareba akadai sekuderedzwa kwekufamba kana kurwadziwa kusingaperi. Kana iwe uchinzwa kurwadziwa kwemaoko mushure mekutambudzika, kupindira panguva yakakodzera kunokosha.

Biomechanics yeMetacarpal Fractures

Kubva pane biomechanical maonero, metacarpal mapfupa anoiswa pasi peaxial kurodha, kukotama masimba, uye kutenderera kushushikana panguva yezuva nezuva kushandiswa kwemaoko. Kana simba rekunze richidarika muganhu wepfupa, kuputsika kunoitika.

Zvinhu zvinoverengeka zvinokanganisa fracture pateni:

• Kutungamira uye ukuru hwesimba

• Ruoko chinzvimbo pakukanganisa

• Bone density nezera

• Tsandanyama dzinodhonza kubva mukati uye kunze kwemaoko tsandanyama

Semuenzaniso, kuputsika kwechishanu metacarpal mutsipa kunowanzoratidza kushushikana kwevolar nekuda kwekudhonzwa kusingapikiswe kweiyo interossei uye lumbar muscles.

Kusiyana neangulation, kuremara kwekutenderera kungasave pachena paX-ray imaging. Kuchipatara, zvinonyatsoonekwa nekucherechedza kurongeka kwemunwe kana murwere achiita chibhakera.

Kunyangwe madhigirii mashoma ekutenderera anogona kukonzera:

• Kupindirana kweminwe

• Kuderedza kubata zvakanaka

• Kukanganisa kushanda kwenguva refu

Nechikonzero ichi, kuremara kwekutenderera kunoonekwa sechiratidzo chakasimba chekugadziriswa kwekuvhiyiwa, kunyangwe kana kuputsika kuchiratidzika kushoma kubviswa radiographically.

Iyi kiriniki nuance inosiyanisa zvakanyanya nyanzvi yemapfupa ekuongorora kubva kune yakakosha fracture management.

FAQ Chikamu

Ndeapi maitiro ekutyoka anonyanya kuratidza kugadzirisa kwekuvhiya?

Kugadziriswa kwekuvhiya kunonyanya kuratidzwa nekuremara kwekutenderera, kusagadzikana kusagadzikana, kubatanidzwa kwemetacarpal yakawanda, kuvhurika fractures, intra-articular extension, kana kukundikana kwekuvhara kuderedzwa. Pakati peizvi, kutenderera kwemalalignment kunoonekwa sekunyanya kushanda kwakakosha.

Yakawanda sei angulation inoshanda inogamuchirwa mune metacarpal fractures?

Angulation inogamuchirwa inosiyana nedijiti. Kazhinji, kushushikana kukuru kunoregererwa muulnar metacarpals kupfuura mune radial metacarpals. Nekudaro, chero dhigirii rekutenderera deformity haigamuchirwi, zvisinei nekushivirira kweangulation.

Ndezvipi zvinhu zvinonyanya kukanganisa fungidziro yenguva refu?

Zvinhu zvakakosha zveprognostic zvinosanganisira:

• Kururama kwekuputsika kwekuputsika

• Kugadzikana kwekugadzirisa

• Kugadziriswa kwekutanga

• Kusavapo kwekuremara kwekutenderera
