 Okay, so this is a quick demonstration of the femoral triangle with its contents and boundaries and the erector canal. This is the femoral triangle. Superior boundary is formed by the inguinal ligament, the base of the femoral triangle from the anterior superior leg spine to the pubic tubercle. The lateral boundary is formed by the sartorius and the medial boundary is formed by this muscle, the erector longus. The roof was covered by the fascia letter, part of which has been retained here, a tough deep fascia of the thigh which forms a complete investment around the thigh and the other part of the fascia letter has been retained here, this is the fascia letter. This forms a roof and the same fascia letter also continues naturally and in an especially thickened portion of the fascia letter is known as the aeotypial tract. The roof has got an opening and that opening is called the saphenous opening and we can see the margin of the saphenous opening here. This saphenous opening is pierced by the long saphenous vein and it is covered by a thin membrane which is known as the cribriform fascia, so that is in the roof. The floor of the femoral triangle, the lateral part of the floor is this muscle here, this is the ilio-soas muscle accompanied by the femoral nerve. The ilio-soas muscle comes through the lateral muscular compartment of the sub-ingolent space and forms a lateral part of the floor and the ilio-soas muscle as we know gets inserted into the lecetro can. Going further medially, we have the next muscle here and we can see that muscle when I lift up the femoral vessels. This is the pectinus muscle, we can see it on this side and we can see it from this side also. This is the pectinus muscle. This pectinus muscle is a dual muscle, it's a muscle of the anterior compartment and it is also a muscle of the medial compartment and the next medial most part of the floor is this muscle here, this is the erector brevis. These were all covered by their own fascia which have been removed, so this constitutes the floor. Coming to the contents of the femoral triangle, this was enclosed in a sheath called the femoral sheath and the femoral sheath contained which has been removed and the femoral sheath contains the femoral artery here, laterally the femoral vein medially and the medial most part of the femoral sheath where my instrument has gone in, this is the femoral canal which is a very small canal which is more prominent in females but this is a male cadaver but this is the location of the femoral canal. Apart from that femoral nerve is also a content of the femoral triangle but it is not a content of the femoral sheath, it had its own fascia which is separate from the femoral vessels. Let me tell you about the tributaries and the branches of the femoral artery and the femoral vein respectively. Let's look at the cardinal points of a compass. If this is north, this is east, this is west, we have an artery and a vein coming from the abdomen that is called the superficial epigastric. The artery will come from the femoral artery and the vein will drain into the long subvenous vein or to the femoral vein. From the lateral aspect we have the circumflex, superficial circumflex iliac vein and the superficial circumflex iliac artery, we can see it here. The vein will drain either into the long subvenous or into the femoral vein and the artery will come from the femoral artery and we can see and from the medial side we have this. This is the external pudendal, external pudendal vein will drain into the femoral vein or the long subvenous vein and the external pudendal artery will come from the femoral artery. So these are the three important branches and we can see it here. Apart from that the femoral artery also gives rise to the profond femoris artery which is not visible in this dissection and the femoral vein also receives the long subvenous vein. The femoral artery also gives a genicular branch to the knee joint. The subvenous of the femoral nerve immediately as it comes into the femoral triangle it immediately divides into multiple branches and we can see it here and it distributes itself to all the muscles of the entry compartment. It gives a cutaneous branch one of which has been retained here. This was a long branch and it was supplying the anterior surface of the thigh. Additionally the femoral nerve also gives rise to this branch. This is called the subvenous nerve. It is the longest cutaneous branch of the human body and the longest cutaneous branch of the femoral nerve itself which runs through the ductor canal and it supplies the skin of the medial side with leg up to the medial side of the foot. This is the long subvenous vein which accompanies the subvenous nerve on the medial side of the leg and the medial side of the foot and it opens into the femoral vein by piercing through the triple form fascia. This long subvenous vein is the most common site of a very important clinical condition called varicose veins and when we have a varicose vein then we have to remove the torturous incompetent long subvenous vein but that is not sufficient. After removing the varicose vein long subvenous vein we also have to remove its tributaries namely the superficial circumflex vein, the superficial epigastric vein and the external pudendal vein because if we leave these three veins behind then they can also give rise to recurrence of the varicose city. So therefore this surgery of removing these three tributaries of the long subvenous vein or the femoral vein that is known as trendlenberg operation. So that is the complete surgery after removing the varicose long subvenous vein. So this is a few quick words about the femoral triangle. Let me give a quick overview of the femoral canal though it is this is a male cadaver. This is the location of the femoral canal. Medially is the lacuna ligament and we can feel the lacuna ligament when I dip my finger in. In the case of a femoral hernia which is more common in females when the hernia descends down it comes out through the subvenous opening and we need to reduce the hernia the only way we can reduce it is to cut the lacuna ligament medially and that is the way to reduce the hernia and to be remembered that in 20% of the population there will be an accessory operator artery running behind the lacuna ligament which can be cut in case and produce severe bleeding and last but not the least let us mention quickly about the adductor canal. The adductor canal starts from the apex of the femoral triangle. It starts from here and it ends here. The boundary of the adductor canal is the sartorius and intramedially and the sub sartorial fascia under that. This is the intramedial boundary. The antrolateral boundary is this muscle here. This is the vastus medialis and the posterior boundary is the adductor longus and what are the contents of the adductor canal? We have the femoral artery, the femoral vein and the subvenous nerve. These are the three structures which pass through the adductor canal. This is a diagrammatic representation of a cross section through the right adductor canal to show the boundaries and contents. So that's all for now. If you have any questions or comments please put them in the comment section below. Thank you for watching.
