Inguinal ligament
Arcus inguinalis [ligamentum inguinale]
Definition
The inguinal ligament is the thickened caudal portion of aponeurosis of external abdominal oblique muscle that extends from tuber coxae to eminentia iliopubica.
Budras and Wünsche (1972) substitute a concept of an inguinal arch for the inguinal ligament. Their inguinal arch is composed of lateral, middle, and medial parts, of which the lateral and middle parts often form an inconstant inguinal tract that joins the caudal border of the aponeurosis of the external abdominal oblique and continues on to join the tendon of origin of the pectineus at the prepubic tendon.
