Anterior and medial thigh

What compartment is the quads in?

Anterior

What compartment is the hamstrings in?

Posterior

What compartment is the adductors in?

Medial

What innervates the quads?

Femoral n

What innervates the hamstrings?

sciatic n

What innervates the adductors?

obturator n

What muscles are apart of the anterior compartment?

-Psoas major

-Iliacus

-Sartorius

-Rectus Femoris

-Vastus Lateralis

-Vastus Intermedius

-Vastus medialis (longus)

-Vastus medialis oblique (VMO)

-Articularis Genu

What muscle is this?

-Psoas major

What muscle is this?

Iliacus

What muscle is this?

-Sartorius

What muscle is this?

Recuts femoris

What muscle is this?

Vastus Lateralis

What muscle is this?

Vastus intermedius

What muscle is this?

Vastus medialias (longus)

What muscle is the circle?

Vastus medialis Oblique (VMO)

What muscle is this?

Articularis Genu

What are the branches of the Femoral N in the thigh?

-anterior femoral cutaneous N branches

-Saphenous N

-muscular branches

What are the vessels of the thigh?

Femoral branches into Deep femoral which branches into:

-perforating Aa

-medial femoral circumflex a

-Lateral femoral circumflex a

Cruciate anastomosis

-around the neck and greater trochanter of femur.

-Formed by: first perforating branch off deep femoral, medial and lateral femoral circumflex Aa, branches of femoral

arteries and inferior Gluteal branches

Where are the arteries in Cruciate anastomosis derived from?

Arteries derived from both the external and internal iliac systems surround the femoral neck and have branches that travel along the neck to supply the

head

What happens to the blood supply after an injury to the head of the femur?

No intra-osseus anastomoses are present between the head and neck which can limit the vascular supply to the head of the femur after injury

What are the muscles of the medial compartment of the thigh?

-gracilis

-pectineus

-adductor longus

-adductor brevis

-adductor magnus

-adductor minimus

-obturator externus

What muscle is this?

Gracilis

What muscle is this?

Pectineus

What muscle is this?

adductor longus

What muscle is this?

adductor brevis

What muscle is this?

adductor magnus

What muscle is this?

adductor minimus

What muscle is this?

Obturator externus

Course of obturator N in the thigh

Arises in abdomen from lumbar plexus (L2-4), enters pelvis on deep medial aspect of psoas major, and runs in extraperitoneal fat along lateral wall of pelvis to obturator foramen.

Division of obturator N

Divides into anterior and posterior parts (split by adductor brevis m), with the anterior part traveling between adductor longus and adductor brevis and the posterior part traveling between adductor brevis and adductor magnus

What are the vessels of the medial compartment of the thigh?

-femoral a

-deep femoral a

-obturator a and v

What are the branches of the femoral a in the medial thigh?

muscular branches

What are the branches of the deep femoral a in the medial thigh?

perforating branches

What are the branches of the obturator a and v in the medial thigh?

branch of internal iliac, enters thigh through obturator canal with

obturator N

What does the obturator a supply in the medial thigh?

supplies obturator externus, some supply to adductor Mm and has an

acetabular branch that provides the artery to the head of the femur
