Hip And Gluteal Region Flashcards
What bridges the acetabular notch?
Transverse actabular ligament
What part of the acetabulum is lined by hyaline cartilage?
Lunate surface
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?
Iliofemoral
Which ligament prevents excessive abduction at the hip joint?
Pubofemoral
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?
Orbicular fibers
Where are the orbicular fibers the weakest?
Posteriorly/Inferiorly
What is the most important blood supply to the hip?
Medial Circumflex Femoral Artery
Hilton’s Law
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?
Avascular necrosis
What are the clinical signs of a posterior hip dislocation?
Shortened and internally rotated limb
Sacrotuberous ligament
Attaches to posteromedial surface of pelvis and inserts onto ischial tuberosity
Sacrospinous ligament
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
Piriformis Syndrome
Sciatic nerve is impinged on by the piriformis muscle. Causes pain radiating down the thigh/leg. Often aggravated by sitting.
