What is the subsartorial 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.
Is the subsartorial canal the same as the adductor 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.
What does the Subsartorial Plexus supply?
It transmits the femoral artery, femoral vein (posterior to the artery), nerve to the vastus medialis and the saphenous nerve – the largest cutaneous branch of the femoral nerve. As the femoral artery and vein exit the canal, they are called the popliteal artery and vein respectively.
How Subsartorial plexus is formed?
The subsartorial plexus is formed by: the medial cutaneous nerve of the thigh (a branch of the femoral nerve). the saphenous nerve (a branch from femoral nerve). the cutaneous branch of anterior division of the obturator nerve.
Why is it called Hunters canal?
The subsartorial or the adductor canal (Fig. 6.17) is the space containing the femoral artery and the vein below the femoral triangle. 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.
What is Pectineus muscle?
The pectineus muscle is a hip adductor, one of a group of five large muscles on the medial thigh. The other hip adductors include the adductor longus, adductor brevis, adductor magnus, and gracilis muscles. Activities that use this muscle include: running, skating, kicking a soccer ball, playing basketball.
What muscles are in the adductor canal?
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. Within the canal, the artery is bound closely to the femoral vein by connective tissue.
What is linea aspera?
[ ăs′pə-rə ] n. A longitudinal ridge running down the posterior surface of the shaft of the femur, affording attachment to various muscles including the vastus medialis, adductor longus, adductor magnus, adductor brevis, vastus lateralis, and short head of the biceps.
What movement does the sartorius perform?
The function of the sartorius is unique in that it can serve as both a hip and knee flexor. The origin for the sartorius is the anterior superior iliac spine, sharing this origin with the tensor fascia lata. At the hip, it acts to both flex the hip as well as externally rotate.
Why adductor canal is called Hunter’s canal?
What is patellar plexus?
The patellar plexus is a plexus of fine nerves situated in front of the patella, the ligamentum patellae and the upper end of the tibia. It is formed by contribution from the following: Patellar plexus. Cutaneous nerves of the right lower extremity. Front and posterior views.
What is Hunter’s canal anatomy?
The adductor canal, also known as Hunter’s canal or subsartorial canal, is a cone-shaped intermuscular passageway located in the distal two-thirds of the medial aspect of the thigh. This canal, which is approximately 8 to 15 cm long, extends from the apex of the femoral triangle to the adductor hiatus.
Why does my pectineus hurt?
The most common causes of injury to the pectineus muscle is from over-exertion or over-extension of stride performed by power walkers and some runners, and is often referred to as a groin strain. Localized pain in the groin area, on one side or the other, is a primary indication of injury to the pectineus.
What happens when the pectineus is tight?
The most common symptoms of an injured pectineus muscle are pain, bruising, swelling, tenderness, and stiffness. Pain in the front hip area can mean that you may have strained the primary hip flexor muscles or the hip adductor muscles, or a combination of the two.
Why linea aspera is important?
The linea aspera is a prominent longitudinal ridge or crest, on the middle third of the bone, presenting a medial and a lateral lip, and a narrow rough, intermediate line. It is an important insertion point for the adductors and the lateral and medial intermuscular septa that divides the thigh into three compartments.
What is the significance of linea aspera in the femur?
The linea aspera is the rough, longitudinal, irregular crest on the posterior surface of the shaft of the femur. It is formed by the joining of lateral and medial lips, which may be separated by up to 10 mm [1]. It is divided distally into medial and lateral supracondylar ridges.
Why is sartorius called honeymoon muscle?
Originally Answered: Why is Sartorius known as the honeymoon muscle? It is called so because it causes abduction and lateral rotation at hip joint which would be a critical action for all the action that is required during the Honeymoon. It causes opening of thigh and flexibility of thighs.
Why is the sartorius muscle important?
Function. At the hip it flexes, weakly abducts, and rotates the thigh laterally. At the knee, it can flex the leg; when the knee is flexed, it also rotates the leg medially. This muscle plays an important part in stabilisation of the pelvis—especially in women.
What is femoral triangle?
The femoral triangle in the anterior superior third of the thigh is a sub-fascial space that appears as a triangular depression inferior to the inguinal ligament; the depression is visible when the thigh is abducted, flexed, and laterally rotated.
What is the ligamentum patellae?
pa·tel·lar lig·a·ment. [TA] a strong flattened fibrous band passing from the apex and adjoining margins of the patella to the tuberosity of the tibia; considered by some to be part of the tendon of the quadriceps femoris muscle, in which the patella is embedded as a sesamoid bone.
What is a subsartorial siphonous nerve block?
The subsartorial saphenous nerve block (SSNB) aims to anesthetize the medial aspect of the leg, ankle, and midfoot. It is commonly performed as an adjunct to the sciatic nerve block for lower leg surgery. The adductor canal block (ACB) is similar to the subsartorial saphenous nerve block, as the injection occurs in the same anatomical space.
What are the different types of subsartorial blocks?
Three related, but different techniques are the “subsartorial blocks”: the subsartorial saphenous nerve block, the adductor canal block, and the femoral triangle block. The subsartorial saphenous nerve block (SSNB) aims to anesthetize the medial aspect of the leg, ankle, and midfoot.
What nerve innervates the subsartorial plexus?
The subsartorial plexus is a plexus of nerves that is located under the sartorius muscle . The subsartorial plexus is formed by: the medial cutaneous nerve of the thigh (a branch of the femoral nerve ). the saphenous nerve (a branch from femoral nerve).
Where is the sartorius muscle?
roof and medially- the sartorius. It is covered in by a strong aponeurosis, the anteromedial intermuscular septum (subsartorial fascia) which extends from the vastus medialis, across the femoral vessels to the adductor longus and magnus. Lying on the aponeurosis is the sartorius (tailor’s) muscle.
