Medial Fascial Compartment of the Thigh Dr. Vohra

Origin Insertion Nerve Supply Nerve Roots Action Muscles of the Medial Fascial Compartment of the Thigh Muscle Origin Insertion Nerve Supply Nerve Roots Action Gracilis Inferior ramus of pubis, ramus of ischium Upper part of shaft of tibia on medial surface Obturator nerve L2, 3L2, 3, 4L2, 3, 4 Adducts thigh at hip joint; flexes leg at knee joint Adductor longus Body of pubis, medial to pubic tubercle Posterior surface of shaft of femur (linea aspera) Adducts thigh at hip joint and assists in lateral rotation Adductor brevis Inferior ramus of pubis Adductor magnus Inferior ramus of pubis, ramus of ischium, ischial tuberosity Posterior surface of shaft of femur, adductor tubercle of femur Adductor portion: obturator nerve Hamstring portion: sciatic nerve L2,3 & 4 Adducts thigh at hip joint and assists in lateral rotation; hamstring portion extends thigh at hip join Obturator externus Outer surface of obturator membrane and pubic and ischial rami Medial surface of greater trochanter L3, 4 Laterally rotates thigh at hip joint Dr. Vohra

Profunda Femoris Branches Is a branch of femoral artery in the femoral 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 Branches Medial femoral circumflex artery: Give muscular branches to medial compartment Takes 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 Vein The obturator artery Obturator Vein The 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 Vein The obturator vein receives tributaries that correspond to the branches of the artery. It drains into the internal iliac vein. Dr. Vohra

Nerve of Medial Fascial Compartment of the Thigh Obturator Nerve Nerve 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. 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. Vohra

Adductor or Subsartorial Canal Dr. Vohra

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 Dr. Vohra

Adductor canal DIMENSION It extends from the apex of the femoral triangle to adductor hiatus BOUNDARIES Anterioromedial: Sartorius fascia Posterior: Adductor longus magnus Lateral: Vastus medialis CONTENTS: Femoral artery Femoral vein Deep lymph vessels Saphenous nerve Nerve to vastus medialis Anterior division of obturator nerve Dr. Vohra 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 Dr. Vohra
