19
Q

Capsule - encloses

A

the entire joint

20
Q

Labrum - made up of

A

Fibrocartilage

21
Q

Labrum - shape

A

triangular shape - thickest superiorly

Attaches to bony rim of acetabulum, bridging the notch

22
Q

Labrum - serves to

A

deepen the acetabulum

23
Q

Labrum - inner surface is lined with

A

articular cartilage and outer surface connects to joint capsule

24
Q

Iliofemoral ligament (or Y or igament of bigelow)

A

Two bands - starting from AIIS
Medial to distal intertrochanteric line
Lateral to proximal intertrochanteric line

25
Q

Iliofemoral ligament - bands are taut with

A

extension and ER
superior band - with adduction
inferior band - with abduction

26
Q

Pubofemoral ligament - Runs from

A

iliopectineal eminence, superior rami of pubis, obturator crest, and obturator membrane
Laterally blends with capsule
Inserts on distal intertrochanteric line

27
Q

Pubofemoral ligament - taut with

A

Extension, ER and abduction

28
Q

Ischiofemoral ligament - runs from

A

ischium and posterior acetabulum, sup and lat, blending with zona articularis
Attaches to greater trochanter

29
Q

Ischiofemoral ligament is taut with

A

Medial rotation, adduction, and extension

30
Q

Zona Orbicularis - runs from

A

circular pattern around femoral neck

31
Q

Zona Orbicularis - function

A

NO bony attachments

Hold head of femur in acetabulum

32
Q

Inguinal ligament - runs from

A

ASIS medially and inferiorly to pubic tubercle

Forms tunnel for arteries, nerves, veins

33
Q

Bursae - Subtendinous Iliac - located

A

between hip and os pubis

34
Q

Bursae - Iliopectineal - located

A

between tendons of psoas major, iliacus, and capsule

Lies close to femoral nerve

35
Q

Bursae - Ischiofemoral - located

A

Between ischial tuberosity and glut max

Might cause pain in sciatic distribution

36
Q

Bursae - Deep trochanteric - located

A

Between glut max and post lat greater troch

Might cause pain with hip flex and IR due to compression of glut max

37
Q

Bursae - superficial trochanteric - located

A

over greater troch

38
Q

What supplies proximal femur

A

Medial and lateral circumflex

39
Q

What supplies femoral head

A

Small branch off obturator artery

40
Q

What supplies acetabulum

A

branches from superior and inferior gluteal arteries

41
Q

Biomechanics -

A

Convex (femoral head) on Concave (acetabulum)
