Study Notes
Leg Function
- Supports body weight
- Facilitates locomotion and balance
Pelvic Bones
- Irregular shape
- Composed of ilium, pubis, and ischium
Femur
- Head connects to acetabulum
- Neck connects head to shaft
- Greater trochanter is large lateral projection
- Lesser trochanter is smaller medial projection
- Linea aspera is a roughened line along the posterior shaft
- Medial and lateral condyles form articulations with tibia
Deep Fascia of the Thigh
- Known as fascia lata
- Limits outward extension of muscles
- Iliotibial tract (IT tract) forms laterally, extending from iliac crest to below knee
- IT tract aids in leg extension by muscles like tensor fascia lata and gluteus maximus
Superficial Veins of the Leg
- Small saphenous vein runs laterally
- Passes posterior to lateral malleolus
- Drains into popliteal vein
- Great saphenous vein runs medially
- Passes anterior to medial malleolus
- Drains into femoral vein
- Dorsal venous arch connects the two saphenous veins
Varicose Veins
- Dilated, elongated, and tortuous superficial veins
- Caused by incompetent or absent valves
- Blood accumulates in superficial veins
Nerves
- Femoral nerve (L2-L4)
- Motor: Sartorius, Pectineus, Quadriceps
- Sensory: Anterior thigh, medial leg (saphenous nerve)
- Obturator nerve (L2-L4)
- Motor: Adductor longus, brevis, magnus, and gracilis
- Sensory: Skin of medial thigh
Blood Supply
- External iliac artery: continuation of internal iliac
- Femoral artery: continuation of external iliac, palpable at mid-inguinal point
- Deep femoral artery: main artery of anterior compartment, branches into lateral/medial circumflex and perforating branches
- Obturator artery: main artery of medial compartment, branch of internal iliac
Deep Veins
- Great saphenous, small saphenous, popliteal, femoral, external iliac, common iliac, and inferior vena cava (IVC)
Deep Venous Thrombosis (DVT)
- Blood clots form in veins due to inactivity or injury
- Can become emboli if they break loose
- Leads to swelling in peripheral tissues due to obstructed circulation
- Generally occurs in lower extremities
- Can propagate into the femoral veins
Lymphatics
- Superficial inguinal nodes
