Determination of the rotational center of the hip.
We introduce a new method to determine the anatomic rotation center of the hip. In total, 214 healthy hip joints were examined and statistically analyzed. As a reference point we used the intersection between Koehler's line and a line between the upper rims of the two foramina obturatoria. In relation to the reference point the anatomic hip center is localized 7.7% in vertical direction and 17.4% in horizontal direction for male individuals and 7.75 and 15.4% for female individuals, respectively. Those data were referred to the pelvic height. Our data can be used to determine the anatomic hip center in an easy and reliable way, not only for preoperative planning but also for retrospective investigations.
