Other Features

Question 1

Describe the blood supply to the hip joint

Answer 1

• Medial and lateral circumflex arteries (branches of deep femoral artery) which join through joint capsule to supply the femoral neck and hip joint
• Artery of femoral head - within the ligamentum teres
• Nutrient arteries within femoral shaft

Question 2

Describe the Nerve supply to the hip joint

Answer 2

Comes mainly form obturator/sciatic/femoral nerves which also innervate the knee (referred pain)

Question 3

Name the main bursae of the hip and where they lie

Answer 3

• Greater trochanteric bursa - prevents friction between ITB and greater trochanter
• Iliopsoas Bursa - prevents friction between iliopsoas and anterior hip capsule.

Question 4

Describe the borders and contents of the femoral Triangle

Answer 4

Borders: 
Superior: Inguinal Ligament
Medial: Adductor Longus
Lateral: Sartorius
Roof: Skin and Fascia
Floor: Pectineus (med) + Iliopsoas (lat)

Contents: 
Femoral Nerve (lateral-most)
Femoral Artery
Femoral Vein (medial-most)
\+deep inguinal lymph nodes and fat

Question 5

Describe the ITB and Fascia around the hip.

Answer 5

1. ITB = thick band of fascia that runs down the lateral side of the leg - ASIS to gerdys tubercle
   - helps to stabilize the knee
2. Fascia Lata - deep fascia of the thigh - encloses thigh muscles (ITB = thickening of this)
3. Intermuscular septum separate the thigh into 3 compartments:
   Anterior compartment = Quads + sartorius
   Medial Compartment = Adductors + gracilis
   Posterior compartment = Hamstrings
