The femoral canal: the key to femoral herniorrhaphy.

It is conceded by many Authors that femoral hernias not uncommonly result from a previous inguinal herniorrhaphy. Why? A clear visualization of the femoral canal is hampered by the confusing structure of two of its components, the iliopubic tract and the lacunar ligament. Both entities have horizontal as well as vertical extensions. Therefore, a clear understanding of the femoral canal anatomy requires an appreciation of its three dimensional character. The various approaches to femoral hernia are documented. Obliteration of the entire canal by means of a "plug" prosthesis which occludes both the entrance and exit of the canal offers a simple and very effective means of correction. The results of the surgery are documented.
