Femoral Canal

Reading Time:

Overview


The femoral canal is a part of the femoral triangle- It is a potential space for weakness and hernias hence its own separate description.


Gross Anatomy


The femoral canal is a space medial to the femoral vein of the anterior thigh, in which the femoral neurovasculature runs as well as the lymph node of Cloquet. The space allows for expansion of the femoral vein during states of increased venous return from the leg e.g. running. The opening of the femoral canal is marked by the femoral ring. The boundaries of the canal is found in the table below.


Clinical Anatomy


Femoral hernias.

 

These hernias are more common in women (although women are still more likely to have an inguinal hernia) and occur when intra-abdominal contents, escape from their normal cavity, and escape through the femoral ring. Due to the tight neck of the femoral canal, there is a higher risk of strangulation. As a result, these hernias should be surgically repaired.
