A new CT-based diagnostic method of protrusio acetabuli (PA) was introduced. However, prevalence of PA by this method and correlation between PA and other manifestations of @entity1614 ( @entity1614 ) is unknown in Korean @entity1614 @entity1 . This study aimed to investigate the prevalence of PA diagnosed by a CT-based method in Korean @entity1 with @entity1614 , the association of PA with other manifestations of @entity1614 , and the contribution of PA to @entity1614 diagnosis. We retrospectively reviewed the records of 146 @entity1614 @entity1 with the presence of a causative @entity6099 mutation and 146 age- and sex-matched controls from a single tertiary care center. All @entity1614 @entity1 underwent a complete assessment of criteria based on the revised Ghent nosology. PA was assessed quantitatively using a CT-based circle-wall distance (CWD) method. PA was diagnosed in 77.4% of @entity1 in the @entity1614 group and in 11.0% of the control group. CWD was significantly different between the two groups (1.50 mm vs. -0.64 mm, P<0.001). The presence of PA did not correlate with the presence of @entity20377 , aortic root diameter, or history of @entity1580 . The presence of PA did not have a significant impact on the final diagnosis of @entity1614 . Even though the presence of PA does not related to the cardinal clinical features of @entity1614 or influence @entity1614 diagnosis, its presence may be helpful for the suspicion of @entity1614 when @entity1580 or @entity439 is found on CT angiography of the aorta because of the high frequency of PA in @entity1614 @entity1 .
