Bilateral variation of iliacus muscle and splitting of femoral nerve

Awareness in the variations of psoas major muscle and iliacus muscle is useful guide for both in studies ofhuman anatomy and in clinical practice today. It is of significant practical importance for the surgeons andradiologist, to know the form, degree of severity and range of such changes. Images of posterior abdominopelvicwall with such variations may lead to confusion in interpretation. The knowledge of relations of this variationwith neighboring nerves, blood vessels and other structures are important for an accurate diagnosis and toprevent further surgical complications during routine surgery. In our routine dissections with the purposeof preparation of the teaching and museum specimens, it was observed that in one of the elderly Indian malecadaver showed bilateral variant slip of iliacus muscle having two bellies; in addition the femoral nerve alsoshowed variation in its course.
