  • Title: The inguinal ligament and its lateral attachments: correcting an anatomical error.
    Author: Acland RD.
    Journal: Clin Anat; 2008 Jan; 21(1):55-61. PubMed ID: 18092366.
    Abstract:
    The inguinal portions of the internal oblique and transversus abdominis muscles are generally described as arising from the inguinal ligament. Previous authors have shown that this description is incorrect. A new dissection study in 15 lightly embalmed cadavers confirms that in reality the inguinal portions of these muscles arise from a thickened strip of ilipsoas fascia that forms the superolateral part of the ilio-pectineal arch. Details are given of a new dissection technique that fully exposes the deep aspect of the inguinal ligament, without disrupting its continuity. The historical background of the persistent textbook error is explored. It originated at a time when there was widespread descriptive and semantic confusion regarding the structure now known as the inguinal ligament.
