I-InterTAN Intramedullary Nail

I-Intertrochanteric hip fractures ijwayelekile futhi ilimaza ukulimala ikakhulukazi kubantu asebekhulile.I-Trochanteric fractures (TF) iwukuphuka kwesibili okuvame kakhulu kwe-proximal femur ngemva kokuphuka kwentamo yesifazane futhi iyimithombo eyinhloko yokugula nokufa kwabantu abagugile banamuhla.

Ngo-2050, inani lonyaka lokuphuka kwe-hip emhlabeni wonke lilinganiselwa ukuthi lidlula izigidi ezingu-6.3 ngenxa yokuguga kwabantu emazweni amaningi aseNtshonalanga.E-USA iyodwa, inani labaphuka inqulu lilinganiselwa ukuthi lizokhuphuka lisuka cishe ku-320,000 ngonyaka liye ku-580,000 ngo-2040. Lesi sidingo esikhulayo sidala ukungezwani okukhulu kwenkonzo yezempilo mayelana nabasebenzi kanye nezinsiza ezidingekayo ukuphatha lezi ziguli.E-USA, izindleko zokunakekelwa kwezempilo zokuphatha ukuphuka kwenyonga zilinganiselwa ku-$10 billion ngonyaka, kanti umthelela wenkonzo yezempilo yase-UK ulinganiselwa ku-$2 billion ngonyaka.Lezi zindleko aziqhutshwa nje kuphela izindleko zenqubo yokuhlinzwa ebukhali kodwa futhi nokunakekelwa kwangemva kokushuba, okuhlanganisa nokuvuselelwa.Nakuba ukuhlinzwa kwe-hip fracture kuphumelela kakhulu, iziguli zingase zithole ukugula okuphawulekayo mayelana nobuhlungu, ukungakhululeki nokuhamba okulinganiselwe ngesikhathi sokululama kwazo futhi ezimweni eziningi akunakwenzeka ukufeza amazinga angaphambi kokuphuka komsebenzi.Ucwaningo luphinde luphakamise ukuthi kukhona ukuhlobana phakathi kokuqhekeka kwe-hip kanye namazinga akhuphukayo okufa nokufa okungama-30% okubonwa kunabantu abafaniswa neminyaka abanokuphuka kwe-hip nangaphandle.Kodwa-ke, kufanele kuqashelwe okuthile ekuchazeni idatha enjalo, njengoba abantu abaphuka inqulu bangase babe ntekenteke ngokwemvelo futhi babe sengozini yokugula.

Emhlabeni wonke, izehlakalo zokuphuka kwe-proximal femur ziyanda ngenxa yokushintsha kwezibalo zabantu okuholela ekuphakameni kweminyaka yokuphila.

Ukwelashwa kokuhlinzwa kuyisu elilungile lokuphatha ukuphuka kwe-intertrochanteric njengoba kuvumela ukuvuselelwa kusenesikhathi kanye nokululama kokusebenza.

Ukuze kuncishiswe izinkinga zokunganyakazi isikhathi eside, ukungenelela okusebenzayo okufika ngesikhathi okunikeza ukuzinza okuzwakalayo kokuphuka kanye nokugqugquzelwa kwangaphambi kwesikhathi kweziguli kube yisixazululo esithandwayo sokwelashwa kwalezi ziqephu.Uma ukulungiswa kwangaphakathi kwe-dynamic hip screw (DHS) kungenye yezinketho eziyinhloko, kodwa kusebenza kancane ngesehlakalo esiphezulu sokwehluleka ukulungisa kwangaphakathi kwe-TF engazinzile.Ngaphezu kwalokho, le nqubo yokuhlinzwa ingase ibangele ukulahleka kwegazi okukhulu, ukulimala kwezicubu ezithambile, kanye nokuwohloka kwezifo ezikhona ezigulini esezikhulile.Ngakho-ke, amadivaysi okulungisa i-intramedullary asedume kakhulu ngenxa yezinzuzo ze-biomechanical ekwelapheni i-TF engazinzile uma kuqhathaniswa nokulungiswa kwangaphakathi kwe-DHS.

I-Intertan Nail esebenzisa izikulufu ezi-2 ze-cephalocervical ngendlela ehlanganisiwe, ibonisa ukuzinza okukhulayo kanye nokumelana nokuzungezisa ikhanda le-femoral elingaphakathi kokuhlinzwa kanye nangemuva kokuhlinzwa uma kuqhathaniswa nesistimu yezipikili ezivamile ze-intramedullary.Ucwaningo lwe-biomechanical lubonise ukuthi i-Intertan Nail inezinzuzo ezengeziwe ze-biomechanical zokulungiswa kwangaphakathi kokuphuka okungazinzile uma kuqhathaniswa nesistimu yezipikili ye-intramedullary ye-Intertan Nail.Ezinye izifundo zibike ukuthi inqubo yokuhlinzwa ibe nomphumela omuhle womtholampilo kanye nenani eliphansi lezinkinga].Ucwaningo lwe-biomechanical lwe-Nüchtern et al.ibonise ukuthi i-Intertan Nail ifinyelela ukuzinza okwengeziwe ngebanga le-tip apex ephakeme futhi imelana nemithwalo ephakeme.
