Anthropometric method for estimating component sizes in total hip arthroplasty

Figure 1 Standardised anteroposterior pelvic radiograph. A preoperative radiograph of a patient with a degenerative right hip was obtained in the standardised protocol with the feet internally rotated at 15 and with the X-ray beam centered on the superior margin of the symphysis pubis.
