It is the smallest and most medial part of the femoral sheath. It is approximately 1.3cm long. In this article, we shall look at the anatomy of the femoral canal – its borders, contents and clinical relevance.

Learn More Borders The femoral canal is located in the anterior thigh within the femoral triangle. It can be thought of as a rectangular shaped compartment with four borders and an opening: Medial border – lacunar ligament. Lateral border – femoral vein. Anterior border – inguinal ligament. Posterior border – pectineal ligament, superior ramus of the pubic bone, and the pectineus muscle The opening to the femoral canal is located at its superior border, known as the femoral ring. The femoral ring is closed by a connective tissue layer – the femoral septum. This septum is pierced by the lymphatic vessels exiting the canal.

Empty space. Loose connective tissue. The empty space allows distension of the adjacent femoral vein, so it can cope with increased venous return, or increased intra-abdominal pressure.

Clinical Relevance Femoral Hernia The femoral canal is of particular clinical importance, as it a common site of bowel herniation. A hernia is defined as ‘where an internal part of the body pushes through a weakness in the muscle or surrounding tissue wall.’ In a femoral hernia, part of the small intestine protrudes through the femoral ring. It presents as a lump situated inferolateral to the pubic tubercle. This type of herniation is more common in women, due to their wider bony pelvis. The borders of the femoral canal are tough, and not particularly extensible. This can compress the hernia, interfering with its blood supply. A hernia with a compromised blood supply is known as a strangulated hernia. Do you think you’re ready? Take the quiz below Pro Feature - Quiz The Femoral Canal Question 1 of 3 Submitting...

The femoral canal is a small anatomical compartment located in the anterior thigh, specifically within the femoral sheath. It is the most medial part of the femoral sheath and measures approximately 1.3 cm in length. What are the borders of the femoral canal? The femoral canal has four borders: the medial border is formed by the lacunar ligament, the lateral border by the femoral vein, the anterior border by the inguinal ligament, and the posterior border by the pectineal ligament, superior ramus of the pubic bone, and pectineus muscle. What structures are contained within the femoral canal? The femoral canal contains lymphatic vessels that drain the deep inguinal lymph nodes, the lacunar node, loose connective tissue, and an empty space that allows for the distension of the adjacent femoral vein during increased venous return or intra-abdominal pressure. What is the clinical significance of the femoral canal? The femoral canal is clinically significant as it is a common site for femoral hernias, where a portion of the small intestine protrudes through the femoral ring. This condition can lead to complications, such as strangulation of the hernia, particularly due to the non-extensible borders of the canal. How does a femoral hernia present clinically? A femoral hernia typically presents as a lump located inferolateral to the pubic tubercle. This type of hernia is more prevalent in women, attributed to their wider pelvic anatomy, and can become strangulated if blood supply to the herniated tissue is compromised. Rate This Article
