Flashcards in MSK - Hip Joint Deck (9):
1

Name the articulating surfaces of the hip joint

- Acetabulum (depression in the lateral side of the pelvic girdle)

- Head of the femur (fits into the acetabulum)

- Both are covered in articulate cartilage that is thicker in areas that bear more weight

2

What is the function of the ligaments in the hip joint?

Increase stability

3

What is the only intracapsular ligament of the hip joint?

What are its attachments?

- Ligament of head of femur

- Acetabular fossa to fovea of the femur

- Encloses a small portion of obturator artery

4

What are the extracapsular ligaments?

- Iliofemoral

- Pubofemoral

- Ischiofemoral

5

What are the attachments of the iliofemoral ligament?

What is its function?

- Ilium (inferior to AIIS)

- Intertrochanteric line (2 places)

- Prevents hyperextension of the hip

6

What are the attachments of the Pubofemoral ligament?

What is its function?

- Iliopubic eminance and obturator eminance

- Blends with articular capsule

- Prevents excessive abduction and extension

7

What are the attachments of the Ischiofemoral ligament?

What are the functions?

- Ischium

- Greater trochanter

- Excessive extension of the femur

8

How is vascular supply to the hip joint achieved?

- Medial and lateral circumflex arteries

- Medial supplies majority of the blood (damage causes avascular necrosis)

- Lateral has to penetrate through thick iliofemoral ligament to reach hip

9

What type of joint is the hip joint?

Synovial ball and socket
