The stability of the hip joint is dependent on what 3 things?
- Depth of socket
- Strength of joint capsule
- Attachment of muscles crossing joint
What 2 structures are located in the hip socket?
- Acetabular labrum
- Transverse acetabular ligament
Which ligament is a major player in the strength of the joint capsule?
Iliofemoral ligament (Y ligament)
Why is the iliofemoral ligament also called the Y ligament?

The iliofemoral ligament reinforces the fibrous capsule in what direction?
anterior
The iliofemoral ligament resists which movements at the hip while standing?
