Momwe Mungakonzere Zophwanyika za Distal Humerus Pogwiritsa Ntchito Mbale?

Kusamuka kwapang'onopang'ono kwa distal humerus kwa akuluakulu ndi vuto lovuta chifukwa cha zovuta zamagulu a chigongono, zidutswa zazing'ono zosweka, ndi zochepa za fupa la subchondral. Mipingo yam'mbali ndi yapakati ya distal humerus imapanga chimango chokhazikika cha katatu. Dongosolo lokhazikika la katatu limasokonekera pambuyo pa distal humerus fractures, makamaka zovuta zamtundu wa AO C-mtundu.

Chiyambi

M'buku la AO Internal Fixation Technique lofalitsidwa mu 1979, chifukwa cha kung'ambika kwa distal humerus, gulu la AO linanena kuti mbalezo ziyikidwe 90 ° kwa wina ndi mzake, pakati kapena kutsogolo ndi kumbuyo (1).

Masitepe aukadaulo (Mfundo za AO za chithandizo cha fracture)

a: Kukonzanso kwa trochlear ndi capitellum.

bc: Pambuyo pochepetsa zidutswa zitatu za mafupa a articular, borani waya wa Kirschner mbali ina. Waya wa Kirschner utha kugwiritsidwa ntchito ngati waya wowongolera pa screw ya 3.5mm, kapena screw ikhoza kuyikidwa mofananiza ndi waya wa Kirschner.

d: Gwiritsani ntchito waya wa Kirschner kwakanthawi kuti mulumikizane ndi fupa la articular ku shaft ya humeral

e: Kukonza kachidutswa kakang'ono ku humerus, LCP ya anatomic iyenera kuikidwa poyamba pamtunda wa humerus, ndipo mbale ikhoza kuikidwa kumbuyo kwa capitulum popanda cartilage. LCP yapakatikati ya anatomical imatha kuyikidwa pakatikati pa humerus kuti ikhale yokhazikika. Kuwonongeka kwakukulu kwa mafupa kapena kuyambika kwakukulu kwa metaphyseal, kuyika kwa LCPs ziwiri pa 90 ° kwa wina ndi mzake kumalimbikitsidwa, chifukwa kusinthika kumeneku kumapereka kukhazikika kwa biomechanical. Chisamaliro chiyenera kutengedwa kuti musalowe m'malo olumikizirana pogwiritsa ntchito zomangira zokhazikika.

Kuyerekeza kwa mbale zachitsulo zofananira komanso zoyima

Mu 1995 Mechanics Study Kuyerekeza Plates Awiri Ochizira Distal Humeral Fractures, zotsatira za kuyika kwa mbale zisanu ndi chimodzi zinafaniziridwa (A, mbale ziwiri zam'mbuyo; B, mbale yam'mbuyo yam'mimba, yotsatizana ndi mbale ya radial; C, mbale yapakati ndi yam'mbali; D, yapakati mpaka kumtunda kwa m'mwamba, kumbuyo kwa mbale, mbali inayi ndi yozungulira; fractures; F, chitsanzo cha fractures kwambiri comminuted ndi zomangira zapakatikati ndi lateral), kusonyeza kuti fractures ambiri akhoza kuchitidwa ndi mbale iwiri m`malo osiyanasiyana mankhwala, koma kwambiri comminuted fractures, phunziroli anamaliza kuti medial-lateral mbale fixation pamodzi ndi phula fixation kwambiri bwino kuuma ndi mphamvu mtheradi (3).

Ata C (4) et al adawonetsa kuti mbale yoyima yokhala ndi mbale ya posterolateral kuphatikiza zomangira zinayi za 2.7 mm distal inali ndi kukhazikika kofanana ndi kachitidwe ka mbale zofananira pochiza kuthyoka kwa intra-articular ya distal humer. Odwala kusapeza chifukwa kukwiya khungu la ofananira nawo mbale, makamaka woonda ndi okalamba odwala, akhoza kuthetsedwa ndi mbale posterolateral.

Kodi Mungagule Bwanji Ma Implant a Orthopedic ndi Orthopedic Zida?

Za CZMEDITECH , tili ndi mzere wathunthu wa mankhwala opangira opaleshoni ya mafupa ndi zida zofanana, zomwe zimaphatikizapo implants za msana, misomali ya intramedullary, trauma plate, mbale yotsekera, cranial-maxillofacial, prosthesis, zida zamagetsi, okonza kunja, arthroscopy, chisamaliro cha ziweto ndi zida zawo zothandizira.

Kuphatikiza apo, tadzipereka kupitiliza kupanga zinthu zatsopano ndikukulitsa mizere yazogulitsa, kuti tikwaniritse zosowa za maopaleshoni a madokotala ndi odwala ambiri, ndikupangitsanso kampani yathu kukhala yopikisana pamakampani onse apadziko lonse oyika mafupa ndi zida zamagetsi.

Timatumiza kunja padziko lonse lapansi, kuti mutha tilankhule nafe imelo adilesi song@orthopedic-china.com pa mtengo waulere, kapena tumizani uthenga pa WhatsApp kuti muyankhe mwachangu +86- 18112515727 .
