Answer 9

Orienting during hip replacements

Question 10

Question 11

Femur bony ridge

Answer 11

Intertrochanteric line

Question 12

Femur two axis pro and con

Answer 12

Pro = great mobility
Con = lots of force through neck of femur

Question 13

Answer 13

Diagonal = force from many directions

Question 14

Answer 15

Post

Question 16

Around femoral neck, is lateral Cirxumflex ant or post

Answer 16

Ant

Question 17

In hip joint capsule, circumflex arteries branch into

Answer 17

Retinacular arteries

Question 18

Nerves of hip joint

Answer 18

But also obtutator, superior gluteal therefore a femoral nerve block wont stop all pain (but will stop most)

Question 19

Answer 19

Avascular necrosis

Question 21

Two types of neck of femur fractures

Answer 21

Subcapital and Intertrochonteric

Question 22

Answer 22

Head / ball split = no blood supply to it = avascular necrosis

Question 23

Answer 23

True neck = head/ball still gets some blood supply

Question 24

Hip joint dislocation most common direction

Answer 24

Posterior

Question 25
