Inguinal ligament

Ligamentum inguinale ( Pouparti ), or inguinal ligament, is a caudally located tendinous, reinforced strip of the aponeurosis of the obliquus externus abdominis muscle. This ligament extends on the os coxae from the spina iliaca anterior superior to the tuberculum pubicum.

Approximately from the middle of the ligament, a fibrous strip - arcus iliopectineus - divides the subligamentous space into two - lacuna musculorum (laterally) and lacuna vasorum (medially). Muscles, nerves and blood vessels pass through these spaces from the abdominal cavity and from the pelvis to the thigh and then to the entire lower limb.

It divides into three small separate ligaments:


 * ligamentum lacunare (Gimbernati) – bundles that converge medially and line the inner part of the lacuna vasorum;
 * ligamentum reflexum (Collesi) – forms the mediocaudal boundary of the exit of the canalis inguinalis;
 * ligamentum pectineale (Cooperi) – attaches to the tuberculum pubicum.
