a Posterior view of a CT-based 3D animation of a right hip joint in neutral (left) and FABER (right) positions with the corresponding MRI images measuring the (b) proximal intertrochanteric distance (PID, red line) and (c) distal intertrochanteric distance (DID, yellow line), as well as the (d) ischiofemoral space (IFS, green line). The white dashed line in the 3D animation marks the intertrochanteric ridge. Fl, flexion. Ab, abduction. IR, internal rotation. ER, external rotation. n.a.,= not applicable
