- Definition: An oval opening in the superomedial part of the fascia lata, lies 3-4cm inferolateral to the pubic tubercle. It is about 3 cm long and 1.5 cm wide.

- Description:•Above, lateral and below → sharp border called falciform margin.•Covered by a thin perforated part of the superficial fascia called the cribriform fascia (pierced by the great saphenous vein, the 3 superficial branches of the femoral A., and lymphatics).

It transmits the great saphenous vein and other smaller vessels (like superficial epigastric artery and superficial external pudendal artery), as well as the femoral branch of the genitofemoral nerve.

The cribriform fascia, which is pierced by the structures passing through the opening, closes the aperture and must be removed to expose it.
