Hip Joint Flashcards
Which bones are involved in the Hip Joint?
Head of the femur and the acetabulum (ilium, pubis and ichium)
What type of joint is the hip joint?
Synovial ball and socket
Weight bearing joint which is prone to degenerative changes
What movement can the hip joint do?
Extension and Flexion
Abduction and Adduction
External (lateral) and Internal (medial) rotation
Circumduction (all of the above sequentially)
What are the supporting ligaments of the hip joint?
Iliofemoral
Ischiofemoral
Pubofemoral
What are four associated structures of the hip joint?
Acetabular labrum
Acetabular Fossa
Ligament of the head of femur
Bursa
Iliofemoral Ligament
- Loaction (relative to hip joint)
- Attachments
- Action
Iliofemoral Ligament Location - Anterior Attachments - Inferior anterior iliac spine/acetabulum ring to intertrochanteric line of femur Action - Prevents excessive extension Bonus - V shaped
Pubofemoral Ligament
- Loaction (relative to hip joint)
- Attachments
- Action
Pubofemoral Ligament
Location - Inferior Anterior
Attachments - Pubic eminence/adjacent bone to blend with joint capsule/iliofemoral ligament
Action - prevents excessive abduction
Ischiofemoral Ligament
- Loaction (relative to hip joint)
- Attachments
- Action
Ischiofemoral Ligament
Location - Posterior
Attachments - Posterior, ishium part of acetabulum to greater trochanter
Action - Prevents excessive extension
What is the acetabular labrum?
Incomplete ring of fibrocartilage
Ring complete by transverse acetabulum ligament
Deepens socket providing more stability
What passes through the acetabular fossa?
Ligament of head of femur (round ligament)
Artey of head of femur
What is the function of the articular capsule (hip socket)
Allows for hip movement
attaches acetabular labrum (hip) and transverse acetabublum ligament to intertrochanteric line (femur)
