Rehabilitation Practice and Science


Ischiofemoral impingement (IFI) is an uncommon disease characterized by pain and snapping in the hip, buttock, and groin areas. Research articles on IFI are still rare, and comparative articles are lacking. In this case report, we present a patient with pain radiating to the right lower limb for about 3 months. After imaging evaluation, the diagnosis of IFI was made, which was helpful in the ensuing treatment. Magnetic resonance imaging, the gold standard diagnostic method for IFI, revealed a reduced ischiofemoral space and a reduced quadratus femoris space with abnormal morphology and/or concurrent edema centered in the quadratus femoris muscle belly. It is important to keep this potentially-underestimated syndrome in mind when treating posterior hip pain.
