Relationship between crossover sign and anterior center-edge angle.

ABSTRACT

PURPOSE: The aim of this study was to evaluate the relationship between the anterior center-edge angle (ACEA) and lateral center-edge angle (LCEA) and crossover ratio. METHODS: Consecutive patients presenting for evaluation of hip pain were reviewed. The following measurements were recorded and analyzed Crossover ratio, LCEA, ACEA, and alpha-angle. RESULTS: 68 patients met inclusion criteria. The only statistically significant radiographic measurement when stratified by gender was alpha angle (P < 0.001). There was moderate correlation between crossover ratio and ACEA and LCEA with coefficients of -0.48 and -0.48, respectively. CONCLUSION: A correlation exists between crossover ratio and ACEA and LCEA.
