Scaphoid Fracture
Scaphoid fracture ndiyo inonyanya kuparara kwecarpal, inoverengera inenge 70% yevose carpal bone fractures. Nekuda kweiyo yakasarudzika nzvimbo yeanatomical mukati me carpal bone marongero, nyowani scaphoid fractures inowanzopotsa mukuongororwa kwekiriniki. Uyezve, iyo yakasiyana-siyana yevascular supply ye scaphoid inogadzirisa varwere kune zvinetso zvakadai sezvisina-nonunion, avascular necrosis (AVN), uye kusagadzikana kwecarpal mumatanho ekupedzisira. Clinically, scaphoid fractures inonetsa kurapa uye kazhinji inosiya sequelae senge kunoramba kurwadza kweruoko, kurambidzwa kufamba, uye post-traumatic arthritis.
Yakasarudzika Anatomical Basa reScaphoid
The scaphoid ndiro bhonzo rakareba kupfuura mamwe mumutsara wecarpal, rakaumbwa sechikepe chidiki (saka zita rekuti 'scaphoid'). Inotenderera pakati pemitsara yeproximal uye distal carpal, ichiita basa rinokosha mukudzikamisa nekubatanidza mitsara miviri. Mafambiro emaoko akajairika, kusanganisira kuchinjika, kuwedzera, kutsauka kweradial, uye kutsauka kweurnar, zvese zvinoenderana nekufamba kwakarongeka kwe scaphoid. Kana yatsemuka, iyo biomechanics yemubatanidzwa wewrist yese inokanganiswa.
Fragile Vascular Supply
Iyo scaphoid inogamuchira kupihwa kweropa kunyanya kubva kumapazi eradial artery, ichipinda kubva kudorsal ridge uye distal pole:
Inenge 70-80% yekuyerera kweropa inopinda kuburikidza ne distal tubercle, ichiyerera ichidzokorodza kuti idye iyo proximal pole.
Mapazi mashoma chete anopinda zvakananga muproximal pole.
Zvinoreva:
Iyo inoswedera pedyo nekuputsika kune proximal pole, iyo yakawanda yengozi yekukanganiswa kwevascular.
Kana kuyerera kweropa kuchinge kwavhiringidzwa, chikamu cheproximal chinowanikwa zvakanyanya kune AVN uye nonunion.
Common Injury Mechanism
Nzira inonyanyozivikanwa yekukuvara ndeyekudonha paruoko rwakatambanudzwa (FOOSH) .Paunenge uchidonha, vanhu vanongotambanudza ruoko uye vanotambanudza minwe kuti vatore simba nechanza. Iyi inogara ichikuvadza nzira yakakwevera kutarisisa kwekiriniki uye kutsvagisa, uye inonyanya kutaurwa nezvayo neacronym FOOSH.
Kunonoka Kuongororwa kweScaphoid Fracture
Scaphoid fractures inowanzokonzerwa nekukuvara kweFOOSH. Muzviitiko zvinyoro, zviratidzo zvinogona kugumira kumarwadzo mashoma emaoko, zvichiita kuti varwere varegeredze kutsvaga kurapwa. Kunyangwe kana X-rays (AP uye lateral maonero) akatorwa, kuputsika kunogona kusakurumidza kuoneka. Varwere vanogona kudzoka mwedzi gare gare nekurwadziwa kwemaoko kunofambira mberi, panguva iyo kufungidzira kunoratidza chirwere chisingaperi che scaphoid-chinonyanya kunonoka kuongororwa uye kushayikwa kwehwindo rekurapa kwakakwana.
Mazano akakosha ekuongorora:
X-ray imaging inofanira kuitwa kune kukuvara kwese kwemaoko, kusanganisira maonero e scaphoid kana kuputsika kuchifungidzirwa.
Kana X-rays isina kunaka asi kufungidzira kunoramba kuripo, immobilization inofanira kushandiswa, ichiteverwa nekudzokorora kufungidzira mushure memavhiki maviri.
Kukurumidza kusamira kunogona kushanda seyese nzira yekuongorora uye yekurapa.
Kurapa Sarudzo
External Fixation
Fresh, nondisplaced fractures inogona kurapwa ne immobilization. Nekudaro, kugadzirisa kunofanirwa kuve kwakasimba kuti uve nechokwadi chekupora. Yakajairwa plaster kana resin splints inogona kutadza kudzora wrist uye forearm kutenderera, kuderedza kugadzikana.
Plaster Cast Immobilization:
Yakareba-ruoko chigunwe spica cast:
Inoratidzwa kune proximal chikamu chimwe chete muzvitatu kutsemuka (yepamusoro AVN njodzi), vertical/oblique mitsara yekutyoka, uye yekutanga kuongororwa nyaya.
Inomisa gokora pa90°, forearm, wrist, uye chigunwe.
Inopa yakanyanya kugadzikana nekubvisa forearm kutenderera.
Short-arm thumb spica cast:
Inokodzera distal yechitatu fractures, tuberosity fractures, uye yakagadzikana yepakati-waist fractures (yakazotevera nhanho).
Inopa kumwe kunyaradza asi kushoma kugadzikana.
Internal Fixation
Headless Compression Screw (Herbert Screw)
Parizvino chiyero chegoridhe che scaphoid waist fractures.
Herbert Cannulated Compression Screw
Bevelled Cannulated Herbert Screw
Kirschner Wire (K-waya) Kugadzirisa
Nzira yechinyakare asi inobatsira, inowanzobatanidza.
Advantages : inoshanduka, isingadhuri, kukanganiswa kudiki kwevascularity.
Zvakaipa : kugadzikana kushoma, kunoda kugadziriswa kwekunze, njodzi yehutachiona, kubviswa kunodiwa mushure mekupora.
Zviratidzo : kuputsika kwevana, kugadzirisa kwechinguva mukufamba, kubatanidza kune screw fixation.
Cannulated Screw Zvikamu-tambo
Cannulated Screw Zvikamu-tambo
Scaphoid Nonunion
Nekuda kweiyo yakasarudzika vascular kupa, scaphoid waist uye proximal fractures inowanzoitika kune nonunion uye AVN.
Kurapa : Bone grafting (isina-vascularized kana vascularized) yakasanganiswa nekugadzirisa mukati (Herbert screw kana K-wire). Kunyatsoiswa kwegraft uye yakatsetseka articular surface kudzoreredza kwakakosha. Mune zvimwe zviitiko, radial styloidectomy inogona kudikanwa kana mukurumbira webhonzo ukakanganisa panguva yekufamba kwechanza.
Global Pamusoro gumi Herbert Screw Suppliers uye CZMEDITECH Chigadzirwa Overview
Kurapa kwe scaphoid fractures kwakakosha-kwete chete kudzorera basa remaoko asiwo nekuchengetedza hutano hwevarwere uye kukwanisa kushanda. Kusarudza iyo yakakodzera yemukati yekumisikidza mudziyo ndiyo kiyi yekudzivirira matambudziko, kuwana chaiyo kugadzirisa, uye kukurudzira kudzoreredza.
Pakati pemaimplants akasiyana-siyana, the Herbert Screw inomira pachena nekuda kweiyo yakasarudzika dhizaini uye yakasimbiswa kiriniki mashandiro, ichiiita imwe yemidziyo yakakosha muscaphoid fracture management.
