Correlation of the cross-over ratio of the cross-over sign on conventional pelvic radiographs with computed tomography retroversion measurements
Objective To find a correlation between the cross-over ratio of the cross-over sign on conventional anteroposterior (AP) pelvic radiographs and retroversion measurements (‘roof-edge angle’ and ‘equatorial-edge angle) on computed tomography (CT) scans.

| description | Objective
To find a correlation between the cross-over ratio of the cross-over sign on conventional anteroposterior (AP) pelvic radiographs and retroversion measurements (‘roof-edge angle’ and ‘equatorial-edge angle) on computed tomography (CT) scans. This would facilitate the interpretation of the cross-over sign regarding the amount of acetabular retroversion.
Materials and methods
Correctly projected AP pelvic radiographs (2,925 hips) were examined for the presence of the cross-over sign (COS), and the overlap ratio of the COS was measured. On CT scans of the same patients the ‘roof-edge angle’ (RE angle) and the ‘equatorial-edge angle’ (EE angle) were also calculated.
Results
A statistically significant but only weak relationship could be found between the overlap ratio of the COS and the ‘roof-edge angle’ (

A statistically significant but only weak relationship could be found between the overlap ratio of the COS and the ‘roof-edge angle’ (

Conclusion
A relationship between the overlap ratio and orientation measurements on CT scans could be found, but it was less strong than expected.</description><identifier>ISSN: 0364-2348</identifier><identifier>EISSN: 1432-2161</identifier><identifier>DOI: 10.1007/s00256-009-0854-z</identifier><identifier>PMID: 20054536</identifier><identifier>CODEN: SKRADI</identifier><language>eng</language><publisher>Berlin/Heidelberg: Springer-Verlag</publisher><subject>Adolescent ; Adult ; Aged ; Aged, 80 and over ; Algorithms ; Biological and medical sciences ; CT imaging ; Female ; Humans ; Imaging ; Investigative techniques, diagnostic techniques (general aspects) ; Male ; Medical sciences ; Medicine ; Medicine & Public Health ; Middle Aged ; Nuclear Medicine ; Orthopedics ; Osteoarticular system.
