  • Dr. Vohra*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

    BranchesMedial femoral circumflex artery:Give muscular branches to medial compartmentTakes part cruciate anastomosis

    Lateral femoral circumflex artery:

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

  • *Dr. Vohra

  • Dr. Vohra*Profunda Femoris VeinThe profunda femoris vein receives tributaries that correspond to the branches of the artery. It drains into the femoral vein.The obturator arteryIs 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.

  • Dr. Vohra*Obturator NerveNerve of Medial Fascial Compartment of the ThighThe 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.

  • Dr. Vohra*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.

  • *Dr. VohraAdductor or Subsartorial Canal

  • *Dr. VohraAdductor canal Also called as subsartorial canal or Hunters canal It is intermuscular space situated below the sartorius muscle in the middle 1/3rd of the thigh

  • *Dr. VohraDIMENSION It extends from the apex of the femoral triangle to adductor hiatus Adductor canal BOUNDARIESAnterioromedial:Sartorius fascia Posterior:Adductor longus magnusLateral:Vastus medialis

    CONTENTS: Femoral artery Femoral veinDeep lymph vessels Saphenous nerveNerve to vastus medialis Anterior division of obturator nerveSubsartorial plexuses

  • Dr. Vohra*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
