Hip MRI in flexion abduction external rotation for assessment of the ischiofemoral interval in patients with hip pain —a feasibility study

ConclusionHip MRI in the FABER position is feasible, visualizes narrowing of the ischiofemoral interval, and can provoke foveal excursion.Critical relevance statementFABER MRI may be helpful in diagnosing ischiofemoral impingement and detecting concomitant hip instability by overcoming shortcomings of static MR protocols that do not allow visualization of dynamic changes in the ischiofemoral interval and thus may improve surgical decision making.Key points• FABER MRI enables visualization of narrowing of the ischiofemoral interval proximal to the lesser trochanter.• Proximal intertrochanteric distance of ≤ 7 mm accurately predicts quadratus femoris muscle edema.• Foveal excursion was more frequent in hips with quadratus femoris muscle edema.Graphical Abstract
