“Kukwaphuka kwentamo ye-femoral engeyiyo eyabadala, eyona ndlela ixhaphakileyo yokulungisa yangaphakathi lulungiselelo 'lwenxantathu eguqulweyo' enezikrufu ezithathu.Izikrufu ezimbini zibekwe ngokusondeleyo kwi-cortices yangaphambili kunye ne-posterior yentamo ye-femoral, kunye ne-screw enye ibekwe ngezantsi.Kwimboniselo ye-anteroposterior, izikrufu ezibini ezisondeleleneyo ziyadibana, zenza ipateni ye-'2-screw', ngelixa kumbono osecaleni, ipateni ye-'3-screw' iyabonwa.Olu lungelelwaniso luthathwa njengeyona ndawo ifanelekileyo yokubeka izikrufu.
“I-medial circumflex femoral artery yeyona nto iphambili yokunikezela ngegazi kwintloko yesifazane.Xa izikrufu zibekwe 'ngaphakathi-ngaphakathi' ngaphezulu kwendawo yangasemva yentamo ye-femoral, ibeka umngcipheko wokonzakala kwe-iatrogenic vascular, enokuthi ibeke esichengeni unikezelo lwegazi kwintamo ye-femal kwaye, ngenxa yoko, ibe nefuthe lokuphilisa amathambo. "
“Ukuthintela ukwenzeka kwento ethi 'in-out-in' (IOI), apho izikrufu zidlula kwi-cortex engaphandle yentamo yowesifazane, ziphume kwi-cortical bone, kwaye ziphinde zingene kwintamo ye-femoral nentloko, abaphengululi ekhaya nakwamanye amazwe. basebenzise iindlela ezahlukeneyo zovavanyo oluncedisayo.I-acetabulum, ebekwe ngaphezu kwendawo yangaphandle yentamo ye-femal, i-concave depression in the bone.Ngokufunda ubudlelwane phakathi kwezikhonkwane ezibekwe ngaphezu kwenkalo yangasemva yentamo yowesifazane kunye ne-acetabulum kwimbono ye-anteroposterior, umntu unokuqikelela okanye avavanye umngcipheko we-screw IOI. "
▲ Umzobo ubonisa umfanekiso we-cortical bone we-acetabulum kwimbono ye-anteroposterior ye-joint hip.
Uphononongo lubandakanya izigulane ze-104, kwaye ubudlelwane phakathi kwethambo le-cortical ye-acetabulum kunye ne-screws yangasemva ihlolwe.Oku kwenziwa ngokuthelekisa kwi-X-rays kwaye kuncediswe ngokwakhiwa kwakhona kwe-CT emva kokusebenza ukuvavanya ubudlelwane phakathi kwezi zibini.Phakathi kwezigulane ze-104, i-15 ibonise into ecacileyo ye-IOI kwi-X-rays, i-6 yayinedatha ye-imaging engaphelelanga, kwaye i-10 yayinezikrini ezibekwe ngokusondeleyo phakathi kwentamo ye-femoral, eyenza ukuvavanya kungasebenzi.Ngoko ke, amatyala angama-73 asemthethweni afakwe kuhlalutyo.
Kwiimeko ezihlalutyiweyo ze-73, kwi-X-rays, iimeko ze-42 zinezikhonkwane ezibekwe ngaphezu kwethambo le-cortical ye-acetabulum, ngelixa iimeko ze-31 zinezikhonkwane ezingezantsi.Ukuqinisekiswa kwe-CT kubonise ukuba i-IOI phenomenon yenzeke kwi-59% yamatyala.Uhlalutyo lwedatha lubonisa ukuba kwii-X-rays, izikrufu ezibekwe ngaphezu kwethambo le-cortical ye-acetabulum zinemvakalelo ye-90% kunye ne-specific ye-88% ekuqikeleleni i-IOI phenomenon.
▲ I-Case One: I-hip joint X-ray kwimbono ye-anteroposterior ibonisa izikrufu ezibekwe ngaphezu kwethambo le-cortical ye-acetabulum.Iimbono ze-CT coronal kunye ne-transverse ziqinisekisa ubukho be-IOI phenomenon.
▲Ityala lesibini: I-X-ray edibeneyo ye-Hip kwimbono ye-anteroposterior ibonisa izikrufu ezibekwe ngaphantsi kwethambo le-cortical ye-acetabulum.Iimbono ze-CT coronal kunye ne-transverse ziqinisekisa ukuba i-screws yangasemva ingaphakathi ngokupheleleyo kwi-cortex yamathambo.
