Study Notes

Hip Joint Anatomy

  • The iliofemoral ligament reinforces the anterior joint capsule and allows standing with minimal muscular effort.
  • The iliopsoas muscle group attaches at the lesser trochanter.
  • The femoral nerve and the obturator nerve are part of the lumbar plexus.
  • The medial circumflex femoral artery is most important for the femoral head.
  • The obturator externus muscle is responsible for hip external rotation and is considered functionally intrinsic.
  • The obturator ligament is a conduit for the passage of the obturator artery.
