Yintoni na nail intramedullary?
I-Intramedullary nailing lutyando lokulungisa ithambo elaphukileyo kwaye ligcinwe lizinzile. Awona mathambo aqhelekileyo alungiswa yile nkqubo lithanga, i-shin, i-hip kunye nengalo ephezulu. Isikhonkwane esisisigxina okanye intonga ibekwe embindini wethambo. Kuya kukunceda ukwazi ukubeka ubunzima kwithambo.
Isetyenziselwa ntoni isikhonkwane se-intramedullary?
Uninzi lweefractures ze-femoral shaft ziphathwa ngotyando. Uphononongo oluninzi lubonise ukuba ukuzinzisa kotyando kwangoko kunxulumene nokuncipha kweengxaki kunye nokufa. Isikhonkwane se-intramedullary yintsimbi yentsimbi efakwe kwi-medullary cavity yethambo kunye nakwi-fracture ukuze inike inkxaso eqinile kwithambo eliphukileyo. Ukubethelwa kwe-Intramedullary okwangoku kujongwa 'njengomgangatho wegolide' wonyango lwezaphulelo ze-femoral shaft. Izibonelelo ezicetywayo zokubethelwa kwe-intramedullary zibandakanya ukuhlala ixeshana esibhedlele, umanyano olukhawulezayo lokwaphuka kunye nokusetyenziswa kwangoko kwelungu .
Kukho iintlobo ezininzi ezahlukeneyo zezikhonkwane ze-intramedullary kunye neendlela zotyando ezinxulumene nazo ezisetyenziswayo. Enye ingxabano ephambili kukuba ingaba isikhonkwane kufuneka sifakwe kwi-canal edolweni kwaye sityhalele phezulu kumsele (ukubuyisela i-retrograde nailing) okanye kwi-hip kunye nokutyhala phantsi komsele (i-antegrade nailing). Indawo yokungena ye-antegrade nailing (piriformis fossa versuser trochanteric entry) nayo iyaphikisana. Omnye umba ngowokuba izikhonkwane ze-intramedullary kufuneka zifakwe kunye ne-reaming (apho i-medullary cavity yandisiwe phambi kokufakwa kwezikhonkwane) okanye ngaphandle kokubuyisela kwakhona. Ngokufanayo, akukho sivumelwano malunga nemiphumo yeentlobo ezahlukeneyo zezikhonkwane, ezifana nezikhonkwane ezidibeneyo (ezineebholiti zokuvala ezibekwe ngaphesheya kwethambo ekupheleni kwesikhonkwane ukuze zikhuseleke kwindawo) okanye izikhonkwane ze-Ender, apho izikhonkwane ezimbini okanye ngaphezulu zibekwe ngaphakathi kwi-medullary cavity ngendlela ethile yokubamba indawo.
Ngaba isikhonkwane se-intramedullary kufuneka sisuswe?
Izikhonkwane ze-Intramedullary ezisetyenziselwa ukulungiswa kweefractures ze-femal zingafuna ukususwa ngenxa yezizathu ezahlukeneyo. Abanye bacebisa ukuba zonke ezo zikhonkwane zisuswe emva kokuphiliswa kokwaphuka, kanti abanye bakhetha ukususa kuphela ezo zibangela iimpawu.Kungakhathaliseki isizathu, ukususwa kwesikhonkwane se-femoral esingaguqukiyo kunokuba nzima kwaye kudle ixesha.
Indlela yokususa isikhonkwane se-intramedullary?
Beka isigulana kwindawo ethe tye esecaleni usebenzisa ingxowa yeembotyi okanye esinye isixhobo sokubeka kwitafile esebenza ngeradiolucent. Lungiselela umlenze wonke, i-lateral buttock, kunye ne-torso kwiimbambo. Gxotha umlenze ngaphandle ukuze uvumele ukunyakaza kwe-hip epheleleyo kunye nedolo ukuze ubeke indawo. I-Flex i-hip malunga ne-90 °. Susa i-proximal kunye ne-distal Izikrufu zokutshixa ngendlela eqhelekileyo. Beka i-guidewire ethangeni kwaye ufumane umfanekiso we-fluoroscopic we-hip proximal. Lungisa ucingo ukuba luhambelane nesikhonkwane se-femoral kwimbono esecaleni. Krwela umgca ecaleni kocingo, ulubeke empundwini. Ukujikeleza ngaphandle kwethanga kwaye uphawule umgca ngendlela efanayo ukumisela indawo ye-anteroposterior nail. I-intersection yemigca emibini ibonisa indawo ye-incision yokubeka i-extractor. Ukuba ithambo le-heterotopic liza kususwa, i-incision kufuneka yenziwe ibe nkulu. Inxeba landiswa ngokucacileyo ngesikere esikhulu seMayo. Emva kokuba isikhonkwane sifikeleleke isikere sisetyenziselwa ukubamba inxeba livuleke, kuze kufakwe i-3.2 guidewire ecaleni kwesikere de ifikelele esikhonkwaneni. Isikere siyasuswa, kwaye isikhonkwane sesikhokelo sihlengahlengiswa de sidlulele kwisikhonkwane. Imifanekiso ye-Anteroposterior kunye ne-lateral ye-hip ifunyenwe ukuze kuqinisekiswe ukubekwa kwesikhokelo kwisikhonkwane. I-cone-shaped femoral extractor kwi-bar extraction bar ifakwe kwilonda, phezu kwepini yesikhokelo. I-extractor ikrwelwe ngobunono kodwa ngamandla kwisikhonkwane. Ukupasa kokuqala kungenakubandakanya ngokupheleleyo isikhonkwane, kodwa kuya kususa uninzi lwezicubu ezithambileyo ezidibeneyo. I-extractor iphinda ifakwe phezu kwepini yesikhokelo okanye ucingo kwaye igxininiswe kwisikhonkwane ngokunyanzeliswa okwaneleyo ukufuna ukusetyenziswa kwee-wrenches. Imalethi etyhidiweyo isetyenziselwa ukubethelela isikhonkwane ngaphandle. Inxeba liyankcenkceshelwa kwaye livalwe ngendlela eqhelekileyo.
