Purposes Flashcards
Ligament
- Act as a **mechanical constraint **
- Prevent **undesired movement **
- Permit limited amounts of desired movement
Bursae
Reduce friction
Articular Discs
- Shock absorbers
- Assist lubrication
Acetabular labrum
deepens socket (increases stability)
Acetabular fat pad
proprioception
Close packed position of the hip joint
Maximum area of contact
Ligaments are taut (stability)
Iliofemoral inferior band
limits extension, and external rotation
Iliofemoral superior band
limits extension, external rotation, adduction
Pubofemoral
limits extension, external rotation, abduction
Ischiofemoral
limits extension, internal rotation, abduction
Ligamentum teres
Proprioceptive
Greater trochanteric bursae
Reduce friction
Illiopectineal bursae
Reduce friction
Patella
mechanical advantage for knee extension
Synovial Membrane
Communicates with some bursa
Lines the joint capsule
Fibular collateral ligament
- Limits: extension and lateral rotation
- Prevents: adduction
