- Fibrous Labrum
- Transverse Ligament
What are the features of the Joint Capsule that encloses the Hip joint?
Proximal- Membrane is around the acetabulum
Distal: Anteriorly, the membrane attaches to the intertrochanteric line and posteriorly attaches halfway along the neck of the femur
What are the ligaments supporting the Hip Joint?
- Iliofemoral Ligament
- Pubofemoral Ligament
- Ischiofemoral Ligament
- Ligamentum Teres (Ligament of Head)
What are the features of the Iliofemoral Ligament?
- Y-Shaped
2. Lies anterior to the joint and attaches to the intertrochanteric Line
What are the features of the Pubofemoral Ligament?
- Triangular in shape
2. Fibres run inferior to the joint
What are the features of Ischiofemoral Ligament?
- Spiral-shaped
- Fibres run posterior to the joint
- Weakest of the 3 ligaments
- Zona orbicularis
