Q

hip joint capsule

A

-attaches to borders of the articular surfaces of the femur and acetabulum
-forms covering around the ligamentum teres
-reinforced by ligaments

19
Q

what are the anterior ligaments of the hip joint

A

-iliofemoral
-pubofemoral
-inguinal

20
Q

iliofemoral ligament

A

-Y ligament
-ilium inferior to ASIS to anterior femur
-prevents excessive extension

21
Q

pubofemoral limagent

A

-from pubic portion of acetabular ring to anterior femur
prevents excessive abduction

22
Q

inguinal

A

-medial ASIS to later pubic tubercle

23
Q

what is the posterior ligament of the hip joint

A

-ischiofemoral- from ischial rim to acetabulum to anterior joint capsule and femur, prevents excessive extension

24
Q

arterial circulation

A

-right common iliac artery
-left common iliac artery

25
Q

internal common iliac artery becomes…

A

internal becomes the obturator artery

26
Q

external common iliac arteries becomes…

A

external becomes the femoral artery

27
Q

femoral triangle

A

-structure within femoral triangle from medial to lateral
-N- femoral nerve
-A- femoral artery
-V- femoral vein
-L- lymphatics

28
Q

where does the femoral artery descend

A

deep through thing, passes through adductor hiatus to become popliteal artery

29
Q

posterior arteries

A

-inferior gluteal arteries
-superior gluteal arteries
-enter gluteal region from pelvic cavity through greater sciatic foramen

30
Q

superior gluteal artery

A

-originates from posterior trunk of internal iliac artery
-divides into superficial and deep branch
-superficial branch passes through deep surface of gluteus maximus
-deep branch passes between gluteus medius and minimus muscle

31
Q

inferior gluteal artery

A

-originates from anterior trunk of internal iliac artery in pelvic cavity
-exits pelvic cavity with inferior gluteal nerve through greater sciatic foramen inferior to piriformis muscle

32
Q

veins

A

-inferior and superior gluteal veins follow the inferior superior gluteal arteries into pelvis where they join the pelvic plexus

33
Q

lymphatics

A

-deep lymphatic vessels of the gluteal region accompany the blood vessels into pelvic cavity and connect with internal iliac nodes

34
Q

fascia compartments

A

-fascia lata- envelopes entire thigh
-3 intermuscular septa divide thigh into 3 compartments
-all 3 septa attach to linea aspera
-posterior- hamstrings
-medial- adductors
-anterior quadriceps

35
Q

femoral triangle boarders

A

-inguinal ligament
-adductor longus
-sartorius

36
Q

structures in femoral triangle

A

NAVL

37
Q

obturator nerve

A

-arises from lumbar plexus
-anterior branch
-posterior branch
-branches innervate adductor longus, adductor braves, gracilis, obturator externs, anterior adductor magnus

38
Q

anterior branch of obturator nerve

A

-deep to adductor longus
-superficial to adductor brevis

39
Q

posterior branch of obturator nerve

A

-pierces obturator externus
-passes superficially to adductor magnus

40
Q

trochanteric bursa

A

-separates gluteus maximus from greater trochanter

41
Q

gluteofemoral bursa

A

-separtaes gluteus maximus and medius from proximal attachment of vastus lateralis at greater trochanter

42
Q

ischial bursa

A

-separates gluteal maximus from ischial tuberosity

43
Q

iliopsoas bursa

A

separates iliopsoas front hip capsule

44
Q

gluteus medius bursa

A

-separates gluteus medius from greater trochanter
