From: In vivo interrelationships between the gluteus minimus and hip joint capsule in the hip internal rotation position with flexion

Fig. 1

Ultrasound images of the gluteus minimus and joint capsule under rotation in hip flexion. Long axis images of the hip in the coronal plane posterior to the anterior inferior iliac spine. The upper row indicates images of the control group and the lower row, flexion adduction internal rotation (FADIR)-positive group. Images at 20° and 10° external rotations (ER 20° and 10°), 0° external/internal rotation (ER/IR 0°), and 10° internal rotation (IR 10°) in 90° hip flexion are shown from left to right. Squares indicate the regions of interest for orientation measurement
