OBJECTIVES: To assess diagnostic performance of traction MR arthrography of the hip in detection and grading of chondral and @entity75 with arthroscopic comparison. METHODS: Seventy-five MR arthrograms obtained    traction of 73 consecutive @entity1 (mean age, 34.5  years; range, 14-54  years) who underwent arthroscopy were included. Traction technique included weight-adapted traction (15-23  kg), a supporting plate for the contralateral leg, and intra-articular injection of 18-27  ml (local anaesthetic and contrast agent). @entity1 reported on neuropraxia and on @entity158 . Two blinded readers independently assessed femoroacetabular cartilage and labrum lesions which were correlated with arthroscopy. Interobserver agreement was calculated using k values. Joint distraction    traction was evaluated in consensus. RESULTS: No procedure had to be stopped. There were no cases of neuropraxia. Accuracy for detection of @entity75 was 92  %/93  %, 91  %/83  % for acetabular lesions, and 92  %/88  % for femoral cartilage lesions for reader 1/reader 2, respectively. Interobserver agreement was moderate (k   =   0.58) for grading of labrum lesions and substantial (k   =   0.7, k   =   0.68) for grading of acetabular and femoral cartilage lesions. Joint distraction was achieved in 72/75 and 14/75 hips with/without traction, respectively. CONCLUSION: Traction MR arthrography safely enabled accurate detection and grading of labral and chondral lesions. KEY POINTS:     The used traction technique was well tolerated by most @entity1 .     The used traction technique almost consistently achieved separation of cartilage layers.     Traction MR arthrography enabled accurate detection of chondral and @entity75 .
