“…There are two main studies in the literature relating the x-, y-, and z-coordinates of the hip center to pelvic dimensions [3,26]. Both studies involved manual measurements on cadaveric pelves with one relating the three coordinates to pelvic width only [3] and the other also relating them to their three corresponding pelvic dimensions [26]. It is difficult to make direct comparisons between our results and the results obtained in those studies because pelvic dimensions were defined differently ( Fig.…”

“…The difference in the x-coordinate (C x ) may be related to the way the hip center was identified. In the two published studies [3,26], this was accomplished by manually estimating the center of the bony acetabular rim as opposed to 3-D CT measurement used in our study. Using the acetabular rim center as the hip center makes the assumption that the acetabulum is a hemisphere with a smooth rim.…”

Acetabular center positioning has an effect on hip function. However, reported clinical and plain radiographic methods are inaccurate and unreliable for ascertaining acetabular implant location. In an exploratory study we asked whether the normal acetabular position can be derived from simple radiographically measurable pelvic dimensions. We analyzed computed tomographic scans of 37 normal hips using a pelvic frame of reference centered on the ipsilateral anterior-superior iliac spine. We defined the x-, y-, and z-coordinates of the hip center (C x ,C y ,C z ) as a percentage of the corresponding pelvic dimensions (D x ,D y ,D z ). C x /D x averaged 9%, C y /D y 34%, and C z /D z 37%. These ratios had narrow distributions with small confidence intervals. Interobserver agreement tests showed a mean intraclass correlation coefficient of 0.95. We observed gender differences in the ratios of as much as 4%, which correspond to differences of as much as 9 mm in the hip center position. The ratios provide a simple and reliable way of deriving the normal position of the hip center from the pelvic dimensions alone. This gives the surgeon a simple way of planning where the hip center should be and may be particularly helpful in revision hip arthroplasty or in cases involving extensive osteophytes, dysplasia, or protrusio.
