Is adductor canal and adductor hiatus same?

Anatomical Parts The adductor canal (subsartorial, Hunter’s canal) is an aponeurotic tunnel in the middle third of the thigh, extending from the apex of the femoral triangle to the opening in the adductor magnus, the adductor hiatus.

What is adductor hiatus?

The adductor hiatus (AH) can be described as an opening in the aponeurotic distal attachment of adductor magnus muscle, which transmits the femoral artery and vein from the adductor canal in the thigh to the popliteal fossa (1).

Is adductor canal same as femoral canal?

The femoral artery. (Canal not labeled, but region visible at center right.) The adductor canal, also known as the subsartorial canal or Hunter’s canal, is an aponeurotic tunnel in the middle third of the thigh. It extends from the apex of the femoral triangle to the adductor hiatus.

What passes adductor hiatus?

The popliteal artery originates at the adductor hiatus and passes through the popliteal fossa. Before passing deep to the fibrous arch over the soleus muscle, it divides into the anterior and posterior tibial arteries at the distal aspect of the popliteus muscle.

What forms the adductor canal?

The canal contains the femoral artery, femoral vein, and branches of the femoral nerve (specifically, the saphenous nerve, and the nerve to the vastus medialis). It consists of three foramina: superior, anterior and inferior.

What nerve is in the adductor canal?

The saphenous nerve (SN) exits the femoral triangle at its apex and enters the adductor canal immediately lateral to the femoral artery. The saphenous nerve travels through the adductor canal until it diverges from the femoral artery distally.

Where does the adductor canal end?

Distal Border: The AC ends at the adductor hiatus, which is the largest of five fibrous openings within the adductor magnus muscle. As the superficial femoral artery passes distally through the adductor hiatus, it is renamed the popliteal artery.

Where is your adductor canal?

The Hunter’s canal (subsartorial, adductor canal) is an aponeurotic tunnel in the middle third of the thigh, extending from the apex of the femoral triangle to the opening in the adductor magnus, the adductor hiatus.

What is adductor canal block?

The adductor canal block (ACB) is an interfascial plane block performed in the thigh. It anesthetizes multiple distal branches of the femoral nerve including the saphenous nerve and branches of the mixed sensory and motor nerves to the quadricep, as well as branches of the obturator nerve.

Why adductor canal is called Hunter’s canal?

It is known as Hunter’s canal because John Hunter first described the exposure and ligation of the femoral artery for treatment of popliteal aneurysm. The femoral artery and vein pass into the popliteal fossa from the adductor canal by passing through a hiatus in the adductor magnus.

What are adductor canal boundaries?

Anatomical Parts It courses between the anterior compartment of thigh and the medial compartment of thigh, and has the following boundaries: anteriorly and laterally – the vastus medialis. posteriorly – the adductor longus and the adductor magnus. roof and medially- the sartorius.

Is adductor canal a peripheral nerve block?

Adductor Canal Block for Knee Surgeries: An Emerging Analgesic Technique. For years, femoral nerve block (FNB) has been considered as the main peripheral nerve block for postoperative analgesia following knee surgery.
