Posterior pubalgia: proximal hamstring syndrome. Patients with symptomatic femoroacetabular impingement (FAI) and restricted internal rotation may develop a compensatory posterior tilt of the pelvis, which leads to chronic hamstring shortening and predisposition to chronic hamstring tendinopathy. Computed tomography images (left) of the right hip demonstrate FAI and a proximal hamstring avulsion fracture. Coronal magnetic resonance images (right) demonstrate a complete proximal hamstring avulsion with retraction and adjacent hematoma.
