An atypical variational canal in the hip bone

Abstract

We report, to our knowledge, a previously unreported canal on the hip bone belonging to the left side of an adult male skeleton. Anterior aperture of the canal was located just anterior to the auricular surface and the posterior aperture just above the major sciatic notch. The margin of the anterior aperture which is located on the left iliac fossa was regular and in the form of a complete circle. The posterior aperture was possessing more than one foramen which are divided by bony segments. We failed to find the other pair of the hip bone, so we could not determine whether the right hip bone possesses a similar canal or not. In this case report we aimed to evaluate this canal morphometrically and point out its clinical importance.
