Question 3

Head of femur is completely covered with

Answer 3

articular cartilage, except over the fovea capitis

Question 4

Answer 4

Lunate surface which is also covered with cartilage

Question 5

Aceteabular notch

Answer 5

inferomedial part

Question 6

Floor of acetabulum contains

Answer 6

fibroelastic mass

Question 7

Ligaments of the hip joint

Answer 7

articular capsule
iliofemoral ligament
pubofemoral ligament
Ischiofemoral ligament
Ligament capitis femoris 
Acetabular labrum
Transverse acetabular ligament

Question 8

Articular Capsule
Thicker vs thinner
Fibers

Answer 8

Strong and dense fibrous structure
Thicker along anterior and upper parts
Thin posteriorly and inferiorly
Fibers circular and longitudinal and they blend with those of other ligaments

Question 9

Zona Orbicularis

Answer 9

Consists of circular fibers along neck of femur

Question 10

Iliofemoral Ligament 
Shape
Apex
Base
Checks what?
Helps with what?

Answer 10

Triangular in shape
Lies in front of joint
Apex is attached to AIIS
Base is attached to intertrochanteric line
Checks hyperextension and external rotation
Helps maintain erect posture

Question 11

Pubofemoral Ligament
Shape
Base
Apex
CHecks

Answer 11

Triangular in shape
Base attached to superior ramus of pubis and obturator crest
Apex blends with iliofemoral ligament
Checks hyperextension, abduction, and external rotation

Question 12

Ischiofemoral Ligament
Arrangement
Attached
FIbers
When tense
Checks

Answer 12

Spiral arrangement
Attached to body of ischium below and behind acetabulum
Fibers go up and laterally to attach to the femoral neck below greater trochanter
Becomes tense during extension of femur
Checks hyperextension and internal rotation

Question 13

Ligament Capitis Femoris
length
shape
attached? base?
where does it lay
when tense

Answer 13

About 4 cm long, can be absent
Flat and triangular
Attached to fovea and base to transverse ligament
Lies within the joint and is covered by synovial membrane
Becomes tense when flexed thigh is adducted

Question 14

Acetabular labrum

Answer 14

Fibrocartilaginous rim attached to the margin of acetabulum

Question 15

Transverse acetabular ligament

Answer 15

continuation of acetabular labrum across acetabular notch

Contains no cartilage cells

Question 16

Synovial membrane
Attached to what?
Covers what?

Answer 16

LInes the articular capsule and is attached to margins of acetabular surfaces
Covers portion of neck of femur that is located in the joint capsule

Question 17

Arteries derived from

Answer 17

1. Obturator
2. Medial and lateral circumflex femoral
3. inferior and superior gluteal
4. 1st perforating

Question 18

Basal Fracture

Answer 18

at base of neck - usually does not lead to necrosis of head

Question 19

Subcapital Fracture

Answer 19

breaks vessels to head and can lead to necrosis

Question 20

Nerves

Answer 20

1. Femoral
2. Obturator
3. Superior gluteal
