Femoral ring
The femoral ring is the opening at the proximal, abdominal end of the femoral canal,[1] and represents the (superiorly directed/oriented[1]) base of the conically-shaped femoral canal.[1] The femoral ring is oval-shaped,[1] with its long diameter being directed transversely and measuring about 1.25 cm.[1] The opening of the femoral ring is filled in by extraperitoneal fat, forming the femoral septum.[1]

Part of the intestine can sometimes pass through the femoral ring into the femoral canal causing a femoral hernia.
Boundaries
The femoral ring is bounded as follows:[2]
- anteriorly by the inguinal ligament.
- posteriorly by the pectineus and its covering fascia.
- medially by the crescentic base of the lacunar ligament.
- laterally by the fibrous septum on the medial side of the femoral vein.
