“Ngokwephuka kwentamo ye-femoral okungebona abantu abadala, indlela evame ukusetshenziswa kakhulu yokulungisa yangaphakathi ukucushwa 'kunxantathu ohlanekezelwe' ngezikulufu ezintathu.Izikulufu ezimbili zibekwe eduze nentamo yangaphambili nengemuva yentamo yesifazane, futhi isikulufu esisodwa sibekwe ngezansi.Ekubukweni kwe-anteroposterior, izikulufu ezimbili ezisondelene ziyagqagqana, zenze iphethini ye-'2-screw', kuyilapho ekubukeni okuseceleni, iphethini ye-'3-screw' iyabonwa.Lokhu kulungiselelwa kuthathwa njengokuhle kakhulu kokubeka izikulufu.”
“I-medial circumflex femoral artery iwumthombo wegazi oyinhloko ekhanda lesifazane.Uma izikulufi zibekwe 'ngaphakathi-ngaphandle' ngaphezu kwengxenye yangemuva yentamo yesifazane, kubeka engcupheni yokulimala kwemithambo ye-iatrogenic, engase ibeke engcupheni ukunikezwa kwegazi entanyeni yesifazane futhi, ngenxa yalokho, kube nomthelela ekwelapheni kwamathambo."
Ukuvimbela ukwenzeka kwento ethi 'in-out-in' (IOI), lapho izikulufu zidlula ku-cortex yangaphandle yentamo yesifazane, ziphume ethanjeni le-cortical, bese zingena kabusha entanyeni nasekhanda le-femoral, izazi kokubili ekhaya nakwamanye amazwe. basebenzise izindlela zokuhlola ezisizayo ezahlukahlukene.I-acetabulum, etholakala ngaphezu kwesici sangaphandle sentamo yesifazane, ukucindezeleka kwe-concave ethanjeni.Ngokutadisha ubudlelwano phakathi kwezikulufu ezibekwe ngaphezu kwengxenye yangemuva yentamo yesifazane kanye ne-acetabulum ekubukeni kwe-anteroposterior, umuntu angabikezela noma ahlole ubungozi be-screw IOI.”
▲ Umdwebo ubonisa isithombe se-cortical bone se-acetabulum ekubukeni kwe-anteroposterior ye-hip joint.
Ucwaningo lwaluhilela iziguli ze-104, futhi ubudlelwano phakathi kwethambo le-cortical ye-acetabulum nezikulufu ezingemuva kwahlolwa.Lokhu kwenziwa ngokuqhathanisa kuma-X-ray futhi kwahambisana nokwakhiwa kabusha kwe-CT kwangemva kokuhlinzwa ukuze kuhlolwe ubudlelwano phakathi kwalokhu okubili.Phakathi kweziguli ze-104, i-15 ibonise into ecacile ye-IOI kuma-X-ray, i-6 yayinedatha ye-imaging engaphelele, futhi i-10 yayinezikulufu ezibekwe eduze kakhulu phakathi kwentamo yesifazane, okwenza ukuhlola kungasebenzi.Ngakho-ke, inani lamacala avumelekile angama-73 afakiwe ekuhlaziyeni.
Ezimweni ezihlaziyiwe ezingu-73, kuma-X-ray, amakesi angu-42 ayenezikulufu ezibekwe ngaphezu kwethambo le-cortical ye-acetabulum, kuyilapho amakesi angu-31 enezikulufu ngezansi.Ukuqinisekiswa kwe-CT kwembula ukuthi i-IOI phenomenon yenzeke ku-59% wamacala.Ukuhlaziywa kwedatha kubonisa ukuthi kuma-X-ray, izikulufu ezibekwe ngaphezu kwethambo lekhohlo le-acetabulum zibe nokuzwela okungu-90% nokucaciswa okungu-88% ekubikezeleni into ye-IOI.
▲ Ikesi Lokuqala: I-X-ray ehlangene ye-Hip ekubukeni kwe-anteroposterior ibonisa izikulufu ezibekwe ngaphezu kwethambo le-cortical ye-acetabulum.Ukubuka kwe-CT coronal kanye ne-transverse kuqinisekisa ukuba khona kwe-IOI phenomenon.
▲Icala Lesibili: I-X-ray yejoyini le-Hip ekubukeni kwe-anteroposterior ibonisa izikulufu ezibekwe ngaphansi kwethambo le-cortical ye-acetabulum.Ukubuka kwe-CT coronal kanye ne-transverse kuqinisekisa ukuthi izikulufu ezingemuva zingaphakathi ngokuphelele kwe-bone cortex.
