ADDUCTOR CANAL:- Also known as Hunter's or subsaorial canal. It is an intermuscular space situated on the medial side of the middle one-third of the thigh. Extend -from apex of femoral triangle above to the tendinous opening in adductor Magnus below. Shape:- Triangular on cross section. Boundaries:--Anterolateral wall: vastus medialis.-Posteromedial wall/Floor:Adductor longus above and adductor Magnus below.-Medial wall/Roof: strong fibrous membrane joining Anterolateral and posteromedial walls. Roof overlapped by Saorius. Subsaorial plexus of nerves lies on the fibrous roof of the canal under saorius. Plexus is formed by branches from the medial cutaneous nerve of thigh, the saphenous nerve and the anterior division of the obturator nerve. It supplies skin over fascia lata and neighboring skin. Contents:-1. Femoral aery: enters the canal at the apex of the femoral triangle. Within the canal, it gives off muscular branches and descending genicular branch. It leaves the canal through opening in adductor Magnus to continue as popliteal aery.2. Femoral vein lies posterior to femoral aery( upperclassmen pa) and lateral to the aery ( lower pa).3. Saphenous nerve: cross the femoral aery anteriorly from lateral to medial side.4. Nerve to vastus medialis 5. Branches of two divisions of obturator nerve: Anterior division emerges at the lower border of adductor longus, gives branches to subsaorial plexus and ends by supplying femoral aery. Posterior division of the obturator nerve runs on anterior surface of adductor magus and ends by supplying knee joint. {Reference: BDC 6Epg no.56}
