Hip joint and its muscles

1
Q

Hip joint, art. coxae

  1. General features
  2. Ligaments
  3. Draw the joint
A
  • Art. simplex (two bones)
  • Spheroid joint (multiaxial)
    • Ball-and-socket joint
    • Movement in three planes (restricted by the gluteal and thigh muscles):
      • Ung: During flexion femur is directed obliquely outwards (convexity of abdomen)
      • Ca: Extremely mobile, also for abduction
  • Between facies lunata of acetabulum (os coxae) → caput femoris

Structures:

  • Capsula articularis
    • Lig. iliofremorale (Reinforecment in the cranial part of the capsule)
    • Lig. ischofemorale (car, sus) (reinforecement in the caudal part of the capsule)
    • Lig. pubofemorale (sus) (Reinforcement in the ventral part of the capsule)
  • Labrum acetabulare (Fibrocartilaginous rim enlaging the acetabulum)
  • Lig. capitis femoris (F**ossa acetabuli → fovea capitis ossis femoris)
  • Lig. transversium acetabuli (Bridges incisura acetabuli)
  • Lig. accessorium ossis femoris (eq) (prepubic tendon throug incisuara acetabuli → fovea capitis)
