Case report

During examination of hip bones in the osteology lab of department of anatomy, KG Medical University, Lucknow, UP, India. 3 out 100 hip bones found to have bony projection erupting from pectineal line of pubic bone.

Pectineal line which gives attachment to lacunar ligament, pectineus muscle and conjoint tendon. Bony tubercle arising from pectineal line might be form due to ossification of lacunarligament/ pectineus muscle/ conjoint tendon. These bony spurs may impinge on surrounding structures damaging them creating clinical complications. The knowledge will be of utmost use to anatomists, radiologists, clinicians and anthropologists.
