Study Notes

Hip Anatomy

  • Key Components:
    • Bones:
      • Femur: Connects to the pelvis at the hip joint.
      • Pelvis: Consists of ilium, ischium, and pubis.
    • Joint:
      • Coxofemoral Joint: Permits movement between the acetabulum (pelvis) and the head of the femur.
    • Associated Structures:
      • Cartilage: Covers the acetabulum and femoral head, reducing friction.
      • Ligaments:
        • Iliofemoral ligament: Prevents hyperextension.
        • Pubofemoral ligament: Limits abduction and extension.
        • Ischiofemoral ligament: Prevents hyperextension, contributes to stability.
      • Synovial Bursae: Reduce friction between bones and soft tissues.

Important Muscles

  • Hip Flexors:
    • Psoas Major: Essential for flexion and stabilization.
    • Iliacus: Works with the psoas major.
  • Hip Extensors:
    • Gluteus maximus: Primary hip extensor.
    • Hamstrings: Assist in extension during walking and running.
  • Abductors:
    • Gluteus Medius & Minimus: Stabilize the pelvis during walking.
  • Adductors:
    • Adductor Longus, Brevis, & Magnus: Facilitate adduction of the thigh.

Hip Function

  • Enables movement in multiple planes: flexion, extension, adduction, abduction, rotation.
  • Supports the body's weight in standing and during locomotion.

Common Hip Irregularities

  • Hip Dysplasia: Abnormal development of the hip joint.
  • Arthritis: Inflammation affecting mobility, causing pain.
  • Tendon Injuries: Primarily affecting flexors and extensors.

Hip Vascularization

  • Femoral Artery: Primary blood supply to the hip.
  • Branches of Iliac Arteries: Supply blood to the pelvic area.

Hip Innervation

  • Sciatic Nerve: Controls the hamstrings.
  • Femoral Nerve: Innervates the hip flexor muscles.
