Flashcards in Hip And Gluteal Region Deck (24):
1

What bridges the acetabular notch?

Transverse actabular ligament

2

What part of the acetabulum is lined by hyaline cartilage?

Lunate surface

3

What is the one spot on the head of the femur without articular cartilage?

Fovea (for ligament of the head)

4

What are the 3 ligaments if the hip joint?

Iliofemoral, Pubofemoral, Ischiofemoral

5

Which hip ligament prevents hyperextension of hip joint?

Iliofemoral

6

Which ligament prevents excessive abduction at the hip joint?

Pubofemoral

7

What is the weakest ligament of the hip joint?

Ischiofemoral (spirals superolaterally)

8

What encircles the hip joint capsule, constricting it around the neck of the femur?

Orbicular fibers

9

Where are the orbicular fibers the weakest?

Posteriorly/Inferiorly

10

What is the most important blood supply to the hip?

Medial Circumflex Femoral Artery

11

Hilton's Law

Nerves that supply muscles that it cross a joint will also give sensory fiber innervation to that joint

12

What is the clinical sign of a femoral neck fracture?

Limb is shortened and externally rotated

13

What is a possible complication of intracapsular fractures?

Avascular necrosis

14

What are the clinical signs of a posterior hip dislocation?

Shortened and internally rotated limb

15

Sacrotuberous ligament

Attaches to posteromedial surface of pelvis and inserts onto ischial tuberosity

16

Sacrospinous ligament

Posterior attachment to ventrolateral surface of sacrum and anterior attachment to ischial spine

17

What forms the greater and lesser sciatic foramen?

Sacrospinous/sacrotuberous ligameents and greater/lesser sciatic notches

18

3 Bursas of thee Gluteal Region

Trochanteric, Ischial, Gluteofemoral

19

What is in the greater sciatic foramen?

Piriformis, Suprapiriform foramen, Infrapiriform foramen

20

What passes thru the suprapiriform foramen?

Superior gluteal nerve

21

What passes thru the infrapiriform foramen?

Inferior gluteal nerve, Sciatic nerve, Posterior femoral cutaneous nerve, obturator internus nerve, Pudendal nerve, Quadratus femoris nerve

22

4 arteries that supply the gluteal region

Superior gluteal artery, inferior gluteal artery, middle circumflex femoral artery, superior perforating artery

23

What are possible complications of injections to the gluteus maximus?

Risk of damage to the sciatic nerve

24

Piriformis Syndrome

Sciatic nerve is impinged on by the piriformis muscle. Causes pain radiating down the thigh/leg. Often aggravated by sitting.
