22
Q

Gluteal Region Nerves and arteries where do they come from and go to (general)

A
  • pelvic cavity– (greater sciatic foramen)–> gluteal region

26
Q

Where do gluteal shots go?

A

outer upper quadrant

27
Q

Hip Joint is what kind of joint?

What is the articulation

A
  • ball and socket
  • head of femur with acetabulum of hip bone
    • lunate surface: w/ articular cartlidge
      • transverse
  • lined with synovial membrane
  • zona orbicularis- thickened portion surrounding the femoral neck
    *
28
Q

Acetabulum

A
  • Indintation is where the round ligament it attached
  • transverse acetabular ligament –> across aetabular notch
29
Q

Ligaments of the hip joint

A

ligimentum terise–> fove capitis

  • iliofemoral ligament
    • anterior ligament, strong, reinforece and streangthen joint
    • twist and tightens when we extend
    • strong
  • pubofemoral ligament
    • prevents hyper abduction
    • splits
  • ischiofemoral ligament
    • weakest one
    • against excessive IR and Flexion
30
Q

Where are hip fractures most common?

A

normally femoral neck

31
Q

Hip joint dislocation;

  • What are the two kinds
A
  • Congentital:
    • acetabilium is shallow because it didnt form well
    • normall bilateral
    • more common in femalle
  • aquired: more agressive, painful
    • posterior
    • sciatic nerve vonerable
    • trendelengburg sign b/c femoral head is higher on affected side
32
Q

Innervation of the hip joint:

  1. Superior part
  2. Inferior part
  3. anterior part
  4. Posterior part
A
  1. Superior gluteal (
  2. obturatior n (L2-L4)
  3. Femoral Nerve (L2-L4)
  4. N. to quadratus femoris (L4-S1)
33
Q

Blood Supply to the hip

A
  • lateral and medial circumflex femoral
  • ​medial circumflex
    • ​retinacular br–> neck and head of femur
