Ipleyiti yokukhiya sisixhobo sokulungisa i-fracture kunye nomngxuma odibeneyo.Xa isikrufu esinentloko enemisonto sijijwe emngxunyeni, ipleyiti iba sisixhobo sokulungisa i-engile (isikrufu).Iipleyiti zentsimbi zokutshixa (i-angle-stable) zinokuba nemingxunya ye-screw yokutshixa kunye nengatshixwanga kwizikrufu ezahlukeneyo eziza kukrujwa kuzo (ekwabizwa ngokuba ziipleyiti zentsimbi ezidityanisiweyo).
1.Imbali kunye nophuhliso
Iipleyiti zokutshixa zaqala ukwaziswa malunga neminyaka engama-20 eyadlulayo ukuze zisetyenziswe kuqhaqho lomnqonqo kunye nolwe-maxillofacial.Ngasekupheleni kwee-1980 kunye nee-1990, izifundo zovavanyo kwiindidi ezahlukeneyo zezixhobo zokulungiswa kwangaphakathi zazisa iipleyiti zokutshixa kunyango lweefractures.Le ndlela yokulungiswa okukhuselekileyo yaphuhliswa ekuqaleni ukuze kugwenywe ukuchithwa kwezicubu ezithambileyo.
Izinto ezininzi ziye zakhuthaza ukusetyenziswa kweklinikhi yeli cwecwe, kuquka:
Iziganeko zokuphulwa kwe-fractures ziqhubeka zikhula njengoko amazinga okusinda aphucula kwizigulane ezinokulimala kwamandla aphezulu kunye nenani lezigulane ezisebekhulile ezine-osteoporosis zanda eNtshona Yurophu naseMntla Melika.
Oogqirha kunye nezigulane abanelisekanga ngeziphumo zonyango kwiifractures ezithile ze-periarticular.
Ezinye izinto ezingezizo ezonyango zingabandakanya: ukukhuthazwa koshishino lweetekhnoloji ezintsha kunye neemarike ezintsha;ukuthandwa kancinci kancinci kotyando, njl.
2.Iimpawu kunye nemigaqo emiselweyo
Umahluko ophambili we-biomechanical phakathi kweepleyiti zokutshixa kunye neepleyiti zendabuko kukuba le yokugqibela ixhomekeke kwi-friction kwi-bone-plate interface ukugqiba ukunyanzeliswa kwethambo ngeplate.
Iziphene ze-biomechanical zamacwecwe ensimbi yendabuko: cinezela i-periosteum kwaye ichaphazele ukunikezelwa kwegazi ukuya ekupheleni kokuphuka.Ke ngoko, i-osteosynthesis yepleyiti esisigxina yemveli (efana ne-interfragmentary compression kunye ne-lag screws) inezinga eliphezulu lokuxakeka ngokwentelekiso, kubandakanya usulelo, ukwaphuka kwepleyiti, ukulibaziseka komanyano, kunye nokungabikho konyuniyoni.
Njengoko umjikelo womthwalo we-axial ukhula, izikrufu ziqala ukukhululeka kwaye zibangele ukukhuhlana kuyancipha, ekugqibeleni kubangele ukuba ipleyiti ikhululeke.Ukuba i-plate iyancipha ngaphambi kokuba i-fracture iphilise, isiphelo sokuphuka siya kungazinzi kwaye ekugqibeleni iplate iya kuphuka.Okukhona kunzima ukufumana nokugcina i-screw fixation eqinile (efana ne-metaphysis kunye ne-osteoporotic bone ends), kunzima kakhulu ukugcina ukuzinza kokuphela kokuphuka.
Umgaqo osisigxina:
Iipleyiti zokutshixa azixhomekekanga kungquzulwano phakathi kojongano lwethambo-pleyiti.Ukuzinza kugcinwa yi-interface ye-angularly stable phakathi kwe-screw kunye ne-steel plate.Ngenxa yokuba olu hlobo lokutshixa isilungisi sangaphakathi sinengqibelelo ezinzileyo, amandla okukhupha isikrufu sentloko yokutshixa iphezulu kakhulu kunezikrufu eziqhelekileyo.Ngaphandle kokuba zonke izikrufu ezijikelezileyo zitsalwe okanye zaphulwe, kunzima ukuba isikrufu sitsalwe okanye siphulwe sodwa.
3.Imiqondiso
Uninzi lweefractures ezinyangwa ngotyando alufuni ukulungiswa kwepleyiti yokutshixa.Ngethuba nje imigaqo yokuhlinzwa kwamathambo ilandelwa, ezininzi iifractures zinokuphiliswa ngamacwecwe endabuko okanye izikhonkwane ze-intramedullary.
Nangona kunjalo, kukho ngokwenene ezinye iindidi ezikhethekileyo zokwaphuka ezithanda ukulahleka kokuncipha, ipleyiti okanye i-screw breakage, kunye ne-nonnunion yamathambo elandelayo.Ezi ntlobo, ezihlala zibizwa ngokuba "zingasonjululwanga" okanye "ingxaki" yokuqhekeka, ibandakanya i-intra-articular comminuted fractures, i-periarticular short bone fractures, kunye ne-osteoporotic fractures.Iifracture ezinjalo zizibonakaliso zokutshixa iipleyiti.
4.Isicelo
Inani elikhulayo labavelisi likwanikezela ngeepleyiti ze-anatomical ezinemingxuma yokutshixa.Umzekelo, iipleyiti ze-anatomic ezenziwe ngaphambili ze-proximal kunye ne-distal femurs, i-proximal ne-distal tibias, i-proximal kunye ne-distal humerus, kunye ne-calcaneus.Uyilo lwepleyiti yensimbi lunciphisa kakhulu uqhagamshelwano phakathi kwentsimbi yentsimbi kunye nethambo kwiimeko ezininzi, ngaloo ndlela kugcinwe ukunikezelwa kwegazi kwe-periosteal kunye ne-perfusion yokuphela kokuphuka.
I-LCP (ipleyiti yokutshixa)
Ipleyiti yokucinezela yokutshixa entsha idibanisa iitekhnoloji ezimbini zokulungiswa kwangaphakathi ezahluke ngokupheleleyo zibe sisifakelo esinye.
I-LCP inokusetyenziswa njengepleyiti yoxinzelelo, i-bracket yangaphakathi yokutshixa, okanye indibaniselwano yezi zibini
Iyahlasela kancinci:
Inani elandayo leepleyiti zokutshixa zinezibambo ze-stent zangaphandle, abanini, kunye noyilo olucacileyo lwengcebiso ezivumela oogqirha ukuba babeke ipleyiti nge-submuscularly okanye i-subcutaneously ngeenjongo ezincinci ezihlaselayo.
