iliac wings often

appears asymmetric in

Answer 18

Sprung-pelvis fracture-dislocation

Question 19

Fracture of the femoral neck may lead to disruption of blood vessels,
resulting in

Answer 19

ischemic osteonecrosis or AVN of the Femoral head

Question 20

: important because of their propensity to damage
the small intracapsular vessels that provide the majority of the blood supply
to the femoral head

extracapsular injuries

Question 23

fractures is used to determine and

predict stability and associated complications with required treatment of subcapital neck fractures.

fractures

Question 25

responsible for undisplaced subcapital neck

fractures

Some complete displaced neck
fractures may mimic pathological
fractures and sometimes referred to
as

Answer 26

pseudopathological fracture

Question 27

during complete displaced
neck fractures the patient will be
unable to walk or stand and their
limb may appear

Answer 27

shortened and

externally rotated

Question 28

Intertrochanteric prox femoral fractures

are often the result of
