Profunda Femoris Is a branch of femoral artery in thefemoral triangle. Descends in the interval between the adductor longus and adductor brevis and then lies on the adductor magnus, ends as the fourth perforating artery

Branches1. Medial femoral circumflex artery:

Give muscular branches to medial compartmentTakes part cruciate anastomosis

2. Lateral femoral circumflex artery:

3. 4 Perforating branches: 3 arise as branches of the profunda femoris artery; the fourth perforating artery is the terminal part of the profunda artery


Profunda Femoris VeinThe profunda femoris vein receives tributaries that correspond to the branches of the artery. It drains into the femoral vein.

The obturator artery

Is a branch of the internal iliac artery.

On entering the medial fascial compartment of the thigh, it divides into medial and lateral branches, It gives off muscular branches and an articular branch to the hip joint.

Obturator VeinThe obturator vein receives tributaries that correspond to the branches of the artery. It drains into the internal iliac vein.


Obturator NerveNerve of Medial Fascial Compartment of the Thigh

The posterior division pierces the obturator externus and passes downward behind the adductor brevis and in front of the adductor magnus

The anterior division passes downward in front of the obturator externus.


The adductor hiatus is a gap in the distal attachment of adductor magnus to the femur, which permits the femoral vessels to pass from the adductor canal downward into the popliteal space.


Adductor or Subsartorial Canal


Adductor canal Also called as subsartorial canal or Hunter’s canal It is intermuscular space situated below the sartorius muscle in the middle 1/3rd of the thigh


DIMENSION It extends from the apex of the femoral triangle to adductor hiatus

Adductor canal

BOUNDARIESAnterioromedial:Sartorius fascia Posterior:Adductor longus magnusLateral:Vastus medialis

CONTENTS: a. Femoral artery b. Femoral veinc. Deep lymph vessels d. Saphenous nervee. Nerve to vastus medialis f. Anterior division of obturator nerve

Subsartorial plexuses


The posterior surface of shaft of the

femur has a ridge, the linea aspera that gives attachment to muscles and intermuscular septa. The medial margins of the linea aspera continues below as the medial supracondylar ridge to the adductor tubercle on the medial condyle
