Abstract:
Objective To explore the diagnostic value of ultrasonography in ischiofemoral impinge-ment syndrome(IFI).Methods Fifty-six patients who underwent hip MRI with confirmed IFI diagnosis and completed ultrasonography examinations were enrolled as the IFI group,including 44 females and 12 males.Twenty healthy volunteers were concurrently recruited as the control group,consisting of 10 females and 10 males.The control group underwent ultrasonography examinations of bilateral hip joints,whiletheischialfemoralspace(IFS)andquadratusfemoristhickness(QFT)of both groups were measured and recorded.Then measurements were compared within(by laterality and gender)and between the two groups using independent-samples t-tests.Moreover,receiver operating characteristic adults,males exhibited significantly higher IFS and QFT values than females(P<0.05).Within the IFI group,males with affected hips had significantly higher IFS than females(P<0.05),while no sig-nificant differences were observed in QFT between different genders(P>0.05).Moreover,affected hips in the IFI group showed significantly narrower IFS and thicker QFT compared to both contralateral hips and the control group(P<0.001).In addition,the diagnostic cut-off values of IFS and QFT for ultrasound diagnosis of IFI were 22.93 mm and 16.48 mm,respectively.At these thresholds,the ar-eas under the curve(AUC)were 0.997 and 0.977,with sensitivities of 97.8%and 91.8%,and speci-ficities of 98.4%and 97.8%,respectively.Conclusion Ultrasound can serve as a reliable diagnostic technique for IFI,where narrowing of the IFS and thickening of the QFT should raise suspicion of this condition.
