Where is the adductor canal located?
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 found in the adductor canal?
Content. The adductor canal contains several neurovascular structures. These structures are the femoral artery, the femoral vein, the descending genicular and muscular branches of the femoral artery and their corresponding venous tributaries, and the saphenous nerve.
What is the clinical significance of the adductor canal?
 Adductor canal block provides excellent pain control and shortens the time of stay in hospital. It preserves quadriceps muscle strength, improved mobility, and reduced risk of fall following total knee arthroplasty. Adductor canal is also called as Hunter’s canal.
What passes through the adductor canal?
The adductor canal is a narrow fascial tunnel in the thigh, providing an intramuscular passage through which the femoral artery and vein pass into the popliteal fossa of the knee (Fig. 5.15).
Where does the adductor canal start?
the femoral triangle
Proximal Border: The AC begins at the apex of the femoral triangle. This is the point where the medial border of the sartorius muscle crosses the medial border of the adductor longus muscle. Some sources cite the apex of the femoral triangle as the lateral border of the adductor longus muscle.
How is adductor canal formed?
Structure. The adductor canal extends from the apex of the femoral triangle to the adductor hiatus. It is an intermuscular cleft situated on the medial aspect of the middle third of the anterior compartment of the thigh, and has the following boundaries: Anteromedial wall – sartorius.
What is an adductor?
adductor muscle, any of the muscles that draw a part of the body toward its median line or toward the axis of an extremity (compare abductor muscle), particularly three powerful muscles of the human thigh—adductor longus, adductor brevis, and adductor magnus.
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.
Which of the following structures enters into and passes through the adductor magnus hiatus?
Four structures are associated with the adductor hiatus. However, only two structures enter and then leave through the hiatus; namely the femoral artery and femoral vein.
What is the action of the adductors?
Originating at the pubis and the ischium (lower portions of the pelvis—the hipbone), these ribbonlike muscles are attached along the femur (thighbone). Their primary action is adduction of the thigh, as in squeezing the thighs together; they also aid in rotation and flexion of the thigh.
What is adductor pollicis?
The main function of the adductor pollicis is to adduct the thumb. Because of the altered plane of the thumb in relation to the palm and other digits, adduction, in this case, refers to bringing the thumb into a position of opposition at the center of the palm.
How long does adductor block last?
How long do the effects of an adductor canal block last? The duration of pain relief after an adductor canal block can range from 18 to 24 hours and sometimes longer. As with any anesthetic, there are risks and benefits to adductor canal blocks. These can be discussed with your anesthesiologist before your surgery.
