What are the boundaries of the adductor canal?

What are the boundaries of the adductor canal?

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.

What are the borders of the adductor hiatus?

Adductor canal

Location	Distal two-thirds of the medial aspect of the thigh
Borders	Proximal border: Apex of femoral triangle Distal border: Adductor hiatus Anterolateral border: Vastus medialis muscle Anteromedial border: Subsartorial fascia Posteromedial border: Adductor longus and magnus muscles

What structure forms the lateral border of the adductor canal?

Structure and Function Some sources cite the apex of the femoral triangle as the lateral border of the adductor longus muscle. However, the most recent consensus maintains that it is the medial border of the adductor longus muscle.

How long is adductor canal?

The average length of the adductor canal is about 10.5 cm in males and 8.5 cm in females. In 36 (90%) lower limbs, the proximal foramen is caudal to the mid-thigh. In four lower limbs (10%) the proximal foramen in cephalad to the mid-thigh.

How many muscles make up the borders of the adductor canal?

This is usually the larger of the two terminating branches. It exits the femoral triangle at the apex and descends into the adductor canal. This canal is bordered by the sartorius muscle medially, vastus medialis anterolaterally, and the adductor longus and magnus muscles posteriorly.

What makes up the borders of the femoral triangle?

The borders of the femoral triangle are composed of the inguinal ligament superiorly, the adductor longus muscle medially, and the sartorius muscle laterally.

Why do adductor canals block?

The adductor canal block is commonly used for analgesia in patients undergoing partial or total knee replacement surgery. Unlike a femoral nerve block, strength in the quadriceps is unaffected, allowing early mobilization or discharge.

What area does an adductor canal block cover?

The saphenous nerve block should be performed at the most distal level where the artery still lies immediately deep to the sartorius muscle, thus minimizing the amount of motor nerve block of the vastus medialis; an adductor canal nerve block is typically performed more proximally, around the mid-thigh level.

How many muscles make up the border of the adductor canal?

Which structure forms the medial border of the femoral triangle?

adductor longus muscle
The borders of the femoral triangle are composed of the inguinal ligament superiorly, the adductor longus muscle medially, and the sartorius muscle laterally.

How many walls does the adductor canal have?

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. Posterior wall – adductor longus and adductor magnus. Laterally – vastus medialis.

What is the adductor canal called?

Hunter’s 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.

Which structure forms the lateral border of the femoral triangle?

The femoral triangle is a wedge-shaped area formed by a depression between the muscles of the thigh. It is located on the medial aspect of the proximal thigh….Borders.

Lateral border	Sartorius
Medial border	Adductor Longus
Base or superior border	Inguinal Ligament

What are the boundaries of the femoral canal?

It can be thought of as a rectangular shaped compartment with four borders and an opening:

• Medial border – lacunar ligament.
• Lateral border – femoral vein.
• Anterior border – inguinal ligament.
• Posterior border – pectineal ligament, superior ramus of the pubic bone, and the pectineus muscle.

Where is adductor canal block given?

thigh
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.

How long does an adductor canal 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.

Is adductor canal block a femoral block?

Abstract. Femoral nerve blocks (FNB) can provide effective pain relief but result in quadriceps weakness with increased risk of falls following total knee arthroplasty (TKA). Adductor canal block (ACB) is a relatively new alternative providing pure sensory blockade with minimal effect on quadriceps strength.

How is adductor canal formed?

Adductor Canal represented in green region. It consists of three foramina: superior, anterior and inferior. The femoral artery with its vein and the saphenous nerve enter this canal through the superior foramen.

Is adductor canal same as femoral canal?

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….
