Kwiminyaka yakutshanje, ngenxa yokwaluphala kwabantu, ukwanda kwamalungu omzimba aqhekekileyo e-proximal femoral kuye kwanda minyaka le. Ngokwezibalo ezingaphelelanga, bekukho malunga ne-1.66 yezigidi zeezigulane eziqhekekileyo e-hip ezinxulumene ne-osteoporosis kwihlabathi liphela ngo-1990, kwaye eli nani kulindeleke ukuba lifikelele kwi-6.26 yezigidi ngo-2050.
Izigulana ezindala ezinee-proximal femoral fractures zijongene nezinga eliphezulu lokufa ngenxa yeemeko zomzimba kunye neengxaki ezahlukeneyo. Phakathi kwazo, izinga lokufa ngenxa yee-intertrochanteric fractures liphezulu njenge-15%–20%.
Ukuqhekeka kwe-intertrochanteric luhlobo oluqhelekileyo lokuqhekeka kwe-hip kubantu abadala, ingakumbi abo bane-osteoporosis. Ngokwahlukileyo koko, abaguli abancinci badla ngokuba nokulimala okunamandla amakhulu.
Unyango lotyando lwezaphuko ze-intertrochanteric luquka iindlela ezahlukeneyo:
Ukulungiswa kwe-Extramedullary, njenge-dynamic hip screw (DHS), i-dynamic condylar screw, njl.
Ukulungiswa kwe-intramedullary, okufana nokuIGammaNulwandle, PI-roximal Femur Nail(PFN), ekufutshaneuzipho lwe-femorali-antirotation (PFNA), i-Intertan, njalo njalo.
Namhlanje sifuna ukwazisaI-Intermedullary Nail edibanisayoiteknoloji.
Eyona nzuzo inkulu yeI-Titanium FemoralI-NaiI-l ikwindawo yayo yangaphakathi kwe-medullary, enika inkxaso ye-intramedullary yoomatshini kwaye ithintela ukuwohloka okugqithisileyo, kwaye oku phantse kuxhomekeke ekubeni i-cortex esecaleni inawo na amandla okuxhasa.
Ukongeza, indawo ye-intramedullary enengalo emfutshane yesikhashana ngokwethiyori inika iingenelo ze-biomechanical kwaye inokunciphisa ukungasebenzi kakuhle kwezixhobo zokulungisa ngaphakathi. Okwangoku, inkqubo yokulungisa ngaphakathi kwe-medullary ayichaphazeleki kangako yi-coxa vara nokuba i-medial cortex ilahlekelwa yinkxaso. Ke ngoko, ukunciphisa kunye nokulungisa ngokwahlukeneyo ukwaphuka kwe-trochanter engaphantsi kwe-displaced akukhuthazwa ngokubanzi.
I-PFNAI-Intramedullary Nail
Uzipho lwentloko lwe-PFNA lusebenzisa indlela yokutshixa i-spiral blade. I-blade inomphezulu omkhulu kunye nobubanzi obukhula kancinci kancinci. Xa ichaphazeleka ethanjeni, i-spiral blade inokuzijikeleza ngokwayo, isebenzise impembelelo yokucinezela kwithambo, ngaloo ndlela igcina ubunzima bethambo kwaye ifikelele ekusondeleni kwe-blade kunye nethambo.
Oku kwandisa amandla okubambelela kwe-spiral blade. Okwangoku, inika ukhuseleko oluchasene nokujikeleza kunye nozinzo lwe-angular, olunokunciphisa ukwanda kokukhubazeka okufana ne-coxa vara.
I-InterzanI-Intramedullary Nail
I-Intertan sisizukulwana esitsha se-I-Intramedullary Femoral NailYenzelwe ngokukodwa ukwaphuka kwe-femoral phakathi kwe-trochanteric. I-proximal cross-section yayo yi-trapezoidal, ixelisa ulwakhiwo lwenxalenye ekufutshane ye-prostheses yamalungu, ivumela uzipho ukuba luhambelane ngcono nomgodi we-medullary kwaye luhambelane neempawu ze-biomechanical ze-proximal femur.
Okwangoku,I-Intertan Femoral Nailinokugcina ngokupheleleyo isitokhwe samathambo eludongeni olusecaleni lwe-trochanter enkulu ngexesha lotyando kwaye iphucule amandla okumelana nokujikeleza kunye noxinzelelo olusecaleni.
Zombini ezi ntlobo zezinzipho ze-intramedullary zinoyilo olufana nefolokhwe ekude, olunokusasaza uxinzelelo ngempumelelo.izikrufu zokutshixa ezikudeZibekwe kude kakhulu nesiphelo esikude seenzipho eziphambili, ngaloo ndlela zinciphisa umngcipheko wokuqhekeka kwe-femoral ekude.
Ukuba ufuna ukufunda okungakumbi malunga ne-I-Interlocking Nail yeFemur,nceda uzive ukhululekile ukuQhagamshelana nathiIqela lethu liza kukunika inkxaso yobungcali kunye neempendulo.
