MSK Anatomy 2 --> Lower Limb Flashcards
Hip Joint: Type of joint
Synovial
Hip Joint: Stabilised by
- Deep acetabulum
- Ligaments of the hip capsule ( iliofemoral, pubofemoral and ischiofemoral)
- Overlying muscles
Identify the ligaments of the hip Capsule:
- Iliofemoral
- Pubofemoral
- Ischiofemoral

Posterior hip dislocation sign
in posterior dislocation the lower limb will appear shortened and internally rotated.
- The hip Joint is a very stable joint; if dislocation occurs, it is often with association
fracture of acetabulum
- Injections into the buttock should be given in the outer quadrant because
