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

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

Zona Orbicularis - runs from

A

circular pattern around femoral neck

31

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
