Subinguinal Space

00:01 If we then look at the sub England or space in more detail, we can again bring up the inguinal ligament, we can see it running from the anterior superior iliac spine to the pubic tubercle.

00:12 We can see this sub inguinal space is an important space that can be separated into a couple of regions.

00:19 Here we see the iliac, pubic ramus that is helping to separate by this extension of the ligament down towards it from the inguinal ligament.

00:27 Two spaces, a lateral space, this muscular space and a more vascular space which is medial.

00:34 Two areas within the sub inguinal space.

00:38 This muscular space which is more lateral contains iliopsoas muscle, it also contains the femoral nerve.

00:46 So if we then move to this vascular space, we can see we have the femoral artery, the femoral vein, the lacunar ligament, all passing through this femoral canal.

00:56 We also have in this space, some important lymphatic structures.

01:00 So we have the lacunar node, for example.

01:02 And this also is an important weak sights, so structures can herniate through this portion of the sub inguinal space.

01:10 This region that we've just created is known as the femoral canal.

01:14 It allows those structures to pass from the pelvis into the anterior aspect of the thigh.

01:21 And therefore this femoral canal is a really important structure for seeing those two important blood vessels.

01:28 More laterally, we find the femoral nerve.

01:31 These three structures will then be found in the femoral triangle, which we'll come to later on.
