Microinstability continues to gain recognition as a potential cause of pain and functional limitation of the hip in young patients and athletes. Although most research has been focusing on anterior hip instability, posterior hip instability (PHI) and associated conditions like femoro-ischiatic impingement (IFI) have also arisen scientific attention. Imaging is a very important diagnostic step in the work-up of athletes with suspected microinstability of the hip. Recently, weight-bearing magnetic resonance imaging (WB-MRI) has been proposed as an innovative dynamic approach to improve the clinical utility of static conventional musculoskeletal MRI. We present the case of a 19-year-old female professional ballet dancer who had been complaining of right groin and posterior hip pain for about 18 months. In our case, WB-MRI allowed to better identify PHI with a secondary non-structural IFI. Therefore, a conservative rehabilitation program emphasizing stretching, stabilization and balance exercises of hip stabilizers muscles led to full resolution of the symptoms and return to professional athletic activity.
