Diagram of Measurement parameters and scanning planes on pelvic radiographs. A Depicting the different lines and angles measured on pelvic scout view. “o” is the center of femoral head; line “oa” is height of the center of femoral head; line “ob” is femoral offset; line “oc” is the abductor muscle lever arm; angle α is neck-shaft angle. B Illustration of the three anatomical levels at which the gluteus medius muscle was measured. A-C planes (red line) are on the healthy side and a-c planes are on the affected sides.
