Flashcards in Hip And Gluteal Region Deck (24):
What bridges the acetabular notch?
Transverse actabular ligament
What part of the acetabulum is lined by hyaline cartilage?
What is the one spot on the head of the femur without articular cartilage?
Fovea (for ligament of the head)
What are the 3 ligaments if the hip joint?
Iliofemoral, Pubofemoral, Ischiofemoral
Which hip ligament prevents hyperextension of hip joint?
Which ligament prevents excessive abduction at the hip joint?
What is the weakest ligament of the hip joint?
Ischiofemoral (spirals superolaterally)
What encircles the hip joint capsule, constricting it around the neck of the femur?
Where are the orbicular fibers the weakest?
What is the most important blood supply to the hip?
Medial Circumflex Femoral Artery
Nerves that supply muscles that it cross a joint will also give sensory fiber innervation to that joint
What is the clinical sign of a femoral neck fracture?
Limb is shortened and externally rotated
What is a possible complication of intracapsular fractures?
What are the clinical signs of a posterior hip dislocation?
Shortened and internally rotated limb
Attaches to posteromedial surface of pelvis and inserts onto ischial tuberosity
Posterior attachment to ventrolateral surface of sacrum and anterior attachment to ischial spine
What forms the greater and lesser sciatic foramen?
Sacrospinous/sacrotuberous ligameents and greater/lesser sciatic notches
3 Bursas of thee Gluteal Region
Trochanteric, Ischial, Gluteofemoral
What is in the greater sciatic foramen?
Piriformis, Suprapiriform foramen, Infrapiriform foramen
What passes thru the suprapiriform foramen?
Superior gluteal nerve
What passes thru the infrapiriform foramen?
Inferior gluteal nerve, Sciatic nerve, Posterior femoral cutaneous nerve, obturator internus nerve, Pudendal nerve, Quadratus femoris nerve
4 arteries that supply the gluteal region
Superior gluteal artery, inferior gluteal artery, middle circumflex femoral artery, superior perforating artery
What are possible complications of injections to the gluteus maximus?
Risk of damage to the sciatic nerve
