The adductor canal is an intermuscular tunnel that is continuous with the femoral triangle proximally.The femoral artery lies anterior to the femoral vein in the canal.

The saphenous nerve1 is a branch of the sciatic nerve

2 is an exclusively sensory nerve

3 supplies skin on the dorsum of the foot

4 innervates skin on the medial aspect of the knee

5 is a content of the adductor canal

2 is an exclusively sensory nerve T

3 supplies skin on the dorsum of the foot F

4 innervates skin on the medial aspect of the knee T

5 is a content of the adductor canal T

The saphenous nerve is a direct branch of the femoral nerve and does not have a motor component.

The adductor canal1 has a medial boundary formed by adductor longus

2 has a medial boundary formed by adductor magnus

3 contains the saphenous nerve

4 contains the nerve to vastus lateralis

5 contains the profunda femoris artery

The adductor canal1 has a medial boundary formed by adductor longus T

2 has a medial boundary formed by adductor magnus T

3 contains the saphenous nerve T

4 contains the nerve to vastus lateralis F

5 contains the profunda femoris artery F

Both adductor longus and magnus contribute to the medial boundary (ie floor) of the adductor canal. The profunda femoris artery runs behind the adductor canal: not within it!

In the adductor canal1 Sartorius lies deep to vastus lateralis

2 Adductor magnus lies anterior to adductor longus

3 Adductor magnus lies anterior to vastus medialis

4 Gracilis forms the lateral boundary

5 The femoral artery lies anterior to the femoral vein

In the adductor canal1 Sartorius lies deep to vastus lateralis F

2 Adductor magnus lies anterior to adductor longus F

3 Adductor magnus lies anterior to vastus medialis F

4 Gracilis forms the lateral boundary F

5 The femoral artery lies anterior to the femoral vein

5 Adductor longus

The following muscles are boundaries of the adductor canal1 Vastus medialis T

2 Adductor brevis F

3 Gracilis F

Boundaries of the adductor canalAnteriorly – subsartorial fasciaLaterally – vastus medialisPosteromedially – adductor longus above and adductor magnus below

The adductor canal 1 extends from the inguinal ligament to the popliteal fossa

2 contains the nerve to vastus medialis

3 is a common site for atheromatous occlusion of the femoral artery

4 its ventral boundary (roof) is a dense fascial layer that lies deep to sartorius

5 it transmits the saphenous nerve

5 it transmits the saphenous nerve T

The adductor canal extends from the apex of the femoral triangle to the adductor tubercle.

The dense fascial layer deep to sartorius is known as the subsartorial fascia.

Concerning the sartorius muscle 1 It is a flexor of the hip joint

2 Its medial border forms the lateral boundary of the femoral triangle

3 It is crossed on its deep aspect by the lateral cutaneous nerve of thigh

4 It arises from the anterior inferior iliac spine

5 It is innervated by the femoral nerve

2 Its medial border forms the lateral boundary of the femoral triangle

T

3 It is crossed on its deep aspect by the lateral cutaneous nerve of thigh

F

4 It arises from the anterior inferior iliac spine F

5 It is innervated by the femoral nerve T

The lateral cutaneous nerve of thigh, also known as the lateral femoral cutaneous nerve, crosses superficial to Sartorius.

Sartorius arises from the anterior superior iliac spine.

The adductor magnus muscle 1 has a double innervation from the sciatic and

femoral nerves

2 is innervated by the obturator nerve

3 is innervated by the sciatic nerve

4 is attached proximally to the ischial tuberosity

5 forms part of the floor of the femoral triangle

The adductor magnus muscle 1 has a double innervation from the sciatic and

femoral nervesF

2 is innervated by the obturator nerve T

3 is innervated by the sciatic nerve T

4 is attached proximally to the ischial tuberosity T

5 forms part of the floor of the femoral triangle F

Adductor magnus has a double innervation by the sciatic and obturator nerve, not femoral nerve!

Part of adductor magnus does in fact attach to the ischial tuberosity.

It forms the posteromedial boundary of the adductor canal distal to adductor longus.

Concerning the adductor canal1 Its roof is formed by a fascia immediately deep to the

gracilis muscle

2 Its lateral wall is formed by a muscle which is innervated by the obturator nerve

3 Its medial wall is formed by a muscle which is innervated by the femoral nerve

4 Its lateral wall is formed by a muscle which is attached directly to the patella

5 It contains the long saphenous vein

T

5 It contains the long saphenous vein F

The roof of the adductor canal is formed by the subsartorial fascia which, as its name implies, lies beneath the Sartorius, not Gracilis. The lateral wall of the adductor canal is formed by the vastus medialis which is innervated by the femoral nerve, not obturator nerve. The lowest fibres of the vastus medialis attach directly to the medial border of the patella.

The medial wall of the adductor canal is formed by adductor longus and magnus both of which are innervated by the obturator nerve, not femoral nerve.
