Nhanganyaya yenzira yekuwana iyo "radial nerve" mumashure mechienda kune humerus

Kuvhiya kwekuvhiya kwepakati-distal humerus fractures (sekuti izvo zvakakonzerwa ne "wrist-wrestling") kana hosteral osteomyelitis kazhinji inoda kushandiswa kweiyo humende yekuenda kune humerus. Njodzi yekutanga yakabatana nenzira iyi ndeye radial nerve kukuvara. Research has indicated that the probability of iatrogenic radial nerve injury resulting from the posterior approach to the humerus ranges from 0% to 10%, with a permanent radial nerve injury probability ranging from 0% to 3%.

Pasinei nechero pfungwa yeradi nerve kuchengetedzwa, zvakawanda zvidzidzo zvakavimba neBony Anatomical landmarks dzakadai sedunhu reSupracondlar renguruve kana iyo scapula yekuita intraoperative chinzvimbo. Nekudaro, kuwana nerudzi rwiyo panguva yekufunga inoramba ichinetsa uye inosanganisirwa nekukosha kwakakosha.

Mufananidzo weiyo radial nerve yekuchengetedza nzvimbo. Avhareji kureba kubva kune radial nerve ndege kuenda kuiyo yakazotevera central of Humerus inenge 12Cm, ine nzvimbo yekuchengetedza inowedzera 10cm pamusoro peiyo inotevera central central central.

Panyaya iyi, vamwe vaongorori vakasanganisa mamiriro echokwadi emukati uye akayera chinhambwe pakati pemupendero we trics tongens fascia uye nerudzi radial. Ivo vakaona kuti chinhambwe ichi chinogara chichigara uye chine kukosha kwakanyanya kwekunetseka kwepamhepo. Musoro murefu weTriceps brachii muswe tendon inomhanya dzinotanga kusvika, nepo inotevera musoro inoumba arc. Iko kupindirana kweaya ma tandeons anoumba iwo tiripi tenders fascia. Nekutsvaga 2.5CM pamusoro peiyi tip, iyo radial nerve inogona kuzivikanwa.

 Positioning nzira

Nekushandisa iyo Apex yeTriceps Tendon Fascia seRefer, Iyo Radial nerve inogona kuwanikwa nekufamba ingangoita 2.5cm kumusoro.

Kuburikidza nekuverenga kuvhareji yevarwere makumi matanhatu, tichienzanisa nenzira yetsika yekutsvaga nzira yakatora maminetsi gumi nematanhatu, iyi nzira yekumisa yakaderedza ganda incision kune radial nerve kufumura nguva kusvika pamaminitsi matanhatu. Uyezve, zvakabudirira kudzivisa radial nerve kukuvara.

Intraoperative gadziriso macroscopic mufananidzo wepakati-distal 1/3 humerral bracture. Nekuisa tutures mbiri dzinopindirana
Iyo chinhambwe chinotaurwa zvechokwadi zvinoenderana nekureba kwemurwere uye kureba kureba. Mukushandisa zvinoshanda, inogona kuchinjwa zvishoma kubva pane iyo yemurwere emuviri uye huwandu hwemuviri.
