Coronal STIR weighted (A) and contrast-enhanced coronal (B) and axial (C) fast spin-echo T1-weighted magnetic resonance imaging scan of the hip showing external rotators insertional tendinopathy, peritendinitis and irregularities in both trochanters, with small avulsed cortical fragments and enhancement. Schematic representation of the obturator internus, gemellus superior, and gemellus inferior muscles inserting into the greater trochanter and the tension band mechanism, the sum of vector forces in the greater trochanter being nearly perpendicular to the apophyseal plate (D).
