Hip Anatomy

  • Piriformis
  • Superior Gemellus
  • Obturator interunus
  • Inferior Gemellus
  • Quadrator femoris

The blood supply to the femoral head is mostly retrograde:

– Main supply is via an anastamosis of the lateral and medial circumflex femoral artery and superior gluteal artery
– Small nutrient artery which is intramedullary
– Small supply via artery of the ligamentum teres (obturator artery)

Anterior attachment – Intertrochanteric line

Posterior attachment – More proximal midway along the femoral neck
  • Ligaments: iliofemoral ligament, pubofemoral and ischiofemoral
  • Capsule
  • Labrum
  • Bone morphology
  • Muscle
