Hip Anatomy

Question 1

Hip joint

Answer 1

Multiaxial Synovial Ball-and-Socket

Question 2

Ligaments at the hip joint

Answer 2

1. Iliofemoral - Iliac spine and acetabulum to intertrochanteric line, is strongest ligament; forms inverted Y (of Bigelow); limits hyperextension and lateral rotation.
2. Ischiofemoral - Acetabulum to femoral neck posteriorly, Limits extension and medial rotation; is weaker ligament
3. Pubofemoral - Pubic ramus to lower femoral neck, Limits extension and abduction
4. Labrum – Acetabulum, Fibrocartilage that deepens socket.
5. Transverse acetabular - Acetabular notch interiorly, Cups acetabulum to form a socket for femoral head
6. Ligament of head of femur - Acetabular notch and transverse ligament to femoral head, Artery to femoral head runs in ligament
