Table 1 The detection of labrum, ligamentum teres and the contracture of the iliopsoas muscle by MRI and pathology

	Pathology
MRI	Labrum			Ligamentum teres			Contracture of the iliopsoas muscle
MRI	(+)	(—)	Total	(+)	(—)	Total	(+)	(—)	Total
(+)	28	2	30	23	3	26	18	2	20

Count data were assessed by the Kappa test. The consistency of MRI manifestations with the pathological results for labrum, Kappa = 0.718, 95% CI (0.488, 0.948); for ligamentum teres, Kappa = 0.759, 95% CI (0.561, 0.957); for contracture of the iliopsoas muscle, Kappa = 0.813, 95% CI (0.639, 0.988)
The Kappa values indicate fairly good consistencies between MRI imaging and the pathology
