The adductor canal is a passage between the anterior and medial thigh compartments. Let's build it to see its borders and contents!
Adductor magnus and adductor longus make the posterior boundary of the adductor canal.
Let's now add the structures that pass through the adductor canal.
Rotate the donor body and highlight the adductor magnus once again to visualize the two tendinous insertions of this muscle on the linea aspera and medial condyle of the femur. The opening between these tendons is called the adductor hiatus
Add the popliteal artery and vein. Notice that the femoral vessels become the popliteal vessels when they pass through the adductor hiatus.
The saphenous nerve, the terminal cutaneous branch of the femoral nerve, also goes through the adductor canal; however, it exits the canal before the adductor hiatus, so it does not travel through this opening.
This donor body does not have a specific label for the saphenous nerve, but it can be seen as a continuation of the femoral. Add the femoral nerve and observe tis superficial and medial deviation from the femoral vessels before the adductor hiatus.
Not shown is the nerve to vastus medialis, a motor branch from the femoral nerve which travels in the adductor canal to innervate its target muscle.
We have now added all the borders and contents of the adductor canal. Switch to a posterior view to see the popliteal vessels exiting the fully formed adductor canal and the saphenous nerve emerging more medially.
Add the great saphenous vein. If this donor body showed a continuation of the saphenous nerve, it would travel inferiorly and superficially alongside the great saphenous vein.
Try to identify the muscles by yourself before looking at the key below.
Purple - sartorius
Lavender - adductor longus
Aqua - adductor magnus
Pink - vastus medialis
Appreciate the organization of the adductor canal by looking at the cross sections in the left panel.
