Crista phallica (CP) is used to determine sex in anthropology and criminal forensic medicine; however, it does not exist in anatomic and radiological terminology. The purpose of this retrospective study is morphometric analysis of the CP. We studied radiographs displaying several different clinical indications from patients whose bone maturation were fully complete. The crista phallica located on both sides of the medial portion of ischiopubic ramus (IPR) were localized and their peak points were determined. The distance from these peak points to the inner cortex of IPRs were measured, as well as the angles between the tangents passing the peak points from both sides. We determined the distance of the IPR (DIPR) for males and females sequentially as 21.3±3.5 mm, and 17±2.8 mm, angle of CP (ACP) as 149.1±15.7, and 163.5±13.4. It was identified that ACP for females is less than ACP for males (p<0.001). ACP and DIPR alone are not sufficient criteria to determine sex. Therefore, the results of our findings show that it would be more useful to study other specifications and their metric analysis in order to determine sex.
