Anterior Hip Subluxation due to Lumbar Degenerative Kyphosis and Posterior Pelvic Tilt

Figure 4

Comparative plots of the center-edge angle (CEA) measured by a transverse CT slice through the center of the femoral head for the bilateral hip joints versus mean normal values reported by Janzen et al. Our case showed very narrow acetabular coverage from the anterior to lateral area of the femoral head.
