OBJECTIVE: The objective of our study was to investigate the prevalence of imaging features on CT thought to be associated with @entity1743 ( @entity1743 ) and the associations among them. MATERIALS AND METHODS: Of 430 consecutive adult @entity1 (age range, 18-40 years) who underwent hip CT at our institution for hip symptoms or @entity130 surveillance, the asymptomatic hips were selected for the study, which resulted in the inclusion of 473 @entity572 in the study group. Images were obtained using an MDCT scanner and were reformatted using a bone algorithm. The CT images were retrospectively evaluated by two radiologists for features indicative of @entity1743 such as the alpha angle, femoral head-neck offset, acetabular version angle, and center-edge angle. The intraclass correlation coefficient was used to evaluate intra- and interobserver variabilities. Associations among these parameters were evaluated by calculating the odds ratio between each of the parameters separately. RESULTS: Of the 473 asymptomatic @entity572 we studied, 190 (40%) joints showed at least one of the following features on CT: alpha angle greater than 55  , head-neck offset less than 8 mm, acetabular version angle less than 15  , or center-edge angle greater than 40  . At least one feature was found in the hips of male @entity1 (43.2%), which is more frequently than in the hips of female @entity1 (35.4%). There was a high degree of @entity12825 (odds ratio > 2) among these CT findings. CONCLUSION: Imaging features on CT that are known to be associated with @entity1743 are common in asymptomatic adult @entity572 , especially in @entity1 , with a high degree of @entity12825 among the findings.
