 Adductor canal or the sub sartorial canal. This sub sartorial canal is a canal as the term implies under the sartorial muscle. It starts from the apex of the femoral triangle which I mentioned was where the sartorial overlaps the adductor longus. And it's about 15 cm long and it continues and it ends at the adductor hiatus which I shall show you just now. So therefore the medial boundary of the sub sartorial canal or the adductor canal is the sartorial. And under that there is a fascia which I shall show you called the sub sartorial fascia. The lateral boundary is this one. This is the master's medialis muscle and the posterior boundary is this muscle. This is the adductor longus. Now I have reflected the sartorials to show you the sub sartorial fascia and the contents of the adductor canal. This fascia that we have slit open here and we can see one edge of the cut portion here and we can see the other end of the cut portion here. This is the sub sartorial fascia and this has got a plexus, the sub sartorial plexus on it. This is the one which forms a roof or the medial wall of the adductor canal just under the sartorial muscle. We have slit the sub sartorial fascia very carefully and we have progressed along to show the course of the structures inside the adductor canal. One of the contents was the nerve to the vascus medialis. We shall not talk about this any further because this is only finishing at the vascus medialis. The next structure that we can see, this is the sub venous nerve. The sub venous nerve runs in this adductor canal and we can see as we trace it further, at one point it emerges from the sub sartorial canal and we have retained the sub sartorial fascia in this portion just to show where it comes out. So till this much, it is inside the adductor canal. So this is the sub venous nerve and clearly we have the sub venous nerve. The next structure that we can see here is this which I have lifted up here. This is the femoral artery and this is the femoral vein. And to show it the same thing again here, this is the femoral artery and this is the femoral vein. So therefore the most important contents are the nerve to vascus medialis, sub venous nerve, femoral artery, femoral vein. So these are the contents of the adductor canal. While it is in the adductor canal, the sub venous nerve is giving these branches. One is this branch and this pierces through the adductor canal and supplies the skin of the anterior medial thigh. Then we can see it another branch. This also pierces through the adductor canal and it supplies the skin of the medial thigh. Then we can see as I mentioned this sub venous nerve passes out of the adductor canal and we have lifted up the other end of it. We have purposely retained a little bit of the sub sartorial fascia to show you the exact location where we see the sub venous nerve is coming out. Having seen the adductor canal from the left side, now we shall show you the same canal from the right side to give you a different perspective. The adductor canal. For that I have replaced back the sartorials here on top of the adductor longus. The adductor canal starts where the apex of the femoral triangle starts and it goes and ends at the adductor hiatus. Therefore to see that I have reflected the sartorials and this is the location of the adductor canal. So what do we see in the adductor canal? First of all we see this structure here. This is the sub venous nerve. It is coming from the femoral nerve here. This is the longest cutaneous branch of the femoral nerve and the only branch which goes outside the thigh and this runs in the adductor canal. And we can see it very clearly here along its full length. This sub venous nerve after it passes through the adductor canal, it comes out through the adductor canal. It goes under the sartorials and then it comes to the leg and it accompanies the long sub venous nerve and it goes all the way, supplies the medial surface of the leg and little bit of the medial surface of the foot. So this is the sub venous nerve. That is one content. The next content is this. This is the femoral artery and behind that the third content is the femoral vein. And the fourth content is this nerve here. This is the nerve to the vastus medialis which is this muscle here. So these are the contents of the adductor canal. The nerve canal is bounded by the sartorials medially. Under that there was a sub sartorial fascia which has been removed. Laterally it is bounded by the vastus medialis and posteriorly it is bounded by the adductor longus and behind that by the adductor magnus. I shall trace my finger along the femoral vessels and as I trace my finger we can see that it is disappearing in one place. This is the adductor hiatus and my finger has now gone into the pocridial fascia. If you look at my finger you will find that medial to my finger is this tendon here. This is the adductor tendon which is the hamstring component of the adductor magnus coming from the ischial tuberosity. And lateral to my finger is the rest of the adductor magnus which is the adductor component of the adductor magnus. So therefore the adductor hiatus is an opening between the hamstring and the adductor component of the adductor magnus through which the femoral artery in the femoral vein passes and it goes to the pocridial fascia and there it becomes known as the pocridial artery in the pocridial vein. So that is about the adductor hiatus which is the termination of the adductor canal.
