Organization of the Lower Limb

(Front and Medial Sides of Thigh) Dr Dalia Saleh
Anatomy Department Organization of the lower limb
Bony features
Front of the thigh
Medial side of the thigh
Femoral triangle
Adductor canal Objectives Overview Organization of the Lower Limb It is connected to the axial skeleton by
a sacroiliac joint and its ligaments.
It is divided into:
The gluteal region
The thigh
The leg
The foot Important landmarks in the lower limb:
The femoral triangle
The popliteal fossa
The posteromedial aspect of the ankle joint Organization of the Lower Limb Support body weight:
The center of gravity is:
Anterior to the edge of the S2 vertebra in the pelvis
Slightly posterior to the hip joints
Anterior to the knee joint
Anterior to the ankle joint
The ligaments are tight and joints are well supported Function Locomotion:
Flexion and extension at hip joint Function Locomotion:
Abduction and adduction at hip joint Function Locomotion:
Internal and external rotation of the hip joint Function Locomotion:
Flexion and extension at the knee joint
Plantar flexion and dorsiflexion at the ankle joint Function Thigh Femur
Skin, superficial fascia and deep fascia
Medial intermuscular septum
Lateral intermuscular septum
Posterior intermuscular septum
1. Anterior compartment
2. Medial compartment
3. Posterior compartment Compartments of the Thigh Anterior Compartment Muscles:
Sartorius
Iliopsoas
Pectineus
Quadriceps
Region:
Femoral triangle
Contents:
Femoral nerve
Femoral artery
Femoral vein
Femoral LN Anterior Compartment Strap like muscle.
Divides front of thigh into upper medial and lower lateral parts
Origin:
ASIS.
Insertion:
Upper part of medial surface of tibia.
Nerve supply:
Femoral nerve.
Action:
Flexes both hip and knee joints. Sartorius Origin:
Iliacus  iliac fossa of hip bone
Psoas major  Transverse processes, bodies, and intervertebral discs (T12 – L5)
Insertion:
Into lesser trochanter of femur.
Nerve supply:
Psoas (anterior rami of L1, 2, 3).
Iliacus (Femoral nerve).
Action:
Flexes thigh on trunk.
Flexes trunk on thigh (sitting, leaning). Iliopsoas Origin:
Superior ramus of pubis
Insertion:
Upper end of linea aspera of shaft of femur
Nerve supply:
Femoral nerve.
Action:
Flexes and adducts thigh at hip joint Pectineus Origin:
Straight head  AIIS
Reflected head  ilium just superior to the acetabulum
Insertion:
Quadriceps femoris tendon
Nerve supply:
Femoral nerve
Action:
Flexes the thigh at the hip joint
Extends the leg at the knee joint Quadriceps – Rectus Femoris Origin:
Vastus medialis Upper end and shaft of femur
Vastus lateralis  Upper end and shaft of femur
Vastus intermedius  anterior and lateral surfaces of femur
Insertion:
Quadriceps femoris tendon
Nerve supply:
Femoral nerve
Action:
Extends the leg at the knee joint Quadriceps – Vasti Medial Compartment Medial Compartment Muscles:
Adductor longus
Gracilis
Adductor brevis
Adductor magnus
Obturator externus
Region:
Adductor canal
Contents:
Femoral artery
Femoral vein
Saphenous nerve
Nerve to vastus medialis Medial Compartment Origin:
Inferior ramus of pubis, ramus of ischium
Insertion:
Upper part of medial surface of shaft of tibia
Nerve supply:
Obturator nerve (anterior division)
Action:
Adducts thigh at hip joint
Flexes leg at knee joint Gracilis Origin:
Body of pubis, medial to pubic tubercle
Insertion:
Posterior surface of shaft of femur
Nerve supply:
Obturator nerve (anterior division)
Action:
Adducts thigh at hip joint
Lateral rotation of the thigh Adductor Longus Origin:
Inferior ramus of pubis
Insertion:
Posterior surface of shaft of femur
Nerve supply:
Obturator nerve (anterior & posterior divisions)
Action:
Adducts thigh at hip joint
Lateral rotation of the thigh Adductor Brevis Origin:
Inferior ramus of pubis, ramus of ischium, ischial tuberosity
Insertion:
Pubic part  Posterior surface of shaft of femur
Ischial part  Adductor tubercle of the femur
Nerve supply:
Pubic part  Obturator nerve (posterior division)
Ischial part  Sciatic nerve
Action:
Pubic part  Adducts and laterally rotate thigh
Ischial part  Extends hip and flexes knee Adductor Magnus Origin:
Outer surface of obturator membrane and pubic and ischial rami
Insertion:
Medial surface of greater trochanter
Nerve supply:
Obturator nerve (posterior division)
Action:
Laterally rotates thigh Obturator Externus Femoral Triangle
Adductor Canal Site:
Triangular depressed area
At the upper part of the medial aspect of the thigh
Boundaries:
Superiorly: The inguinal ligament
Laterally: The sartorius muscle
Medially: The adductor longus muscle
Floor:
Iliopsoas
Pectineus
Adductor longus Femoral Triangle Contents:
Femoral nerve and its branches
Femoral sheath containing:
Femoral artery and its branches
Femoral vein and its tributaries
Femoral canal
Femoral LN Femoral Triangle Site:
Lies on the medial aspect of the middle third of the thigh beneath the sartorius muscle
Boundaries:
Superiorly: the apex of the femoral triangle
Inferiorly: the opening in the adductor magnus
Posteriorly: The adductor longus and adductor magnus
Laterally: Vastus medialis
Roof: Fascia and sartorius Adductor Canal Contents:
The terminal part of the femoral artery
The terminal part of the femoral vein
The deep lymph vessels
The saphenous nerve
The nerve to the vastus medialis
The terminal part of the obturator nerve Adductor Canal Thank You Thank You
