Q

scaphoid - x ray?

A

AP, Lateral, 2 Oblique X-rays
can be hard to see
need to come back in 6 weeks to redo scan

18
Q

why do you get AVN in scaphoid fracture?

A

it has a retrograde blood supply (like the haemoglobin missed their exit and had to turn around to find the scaphoid bone)

19
Q

externally rotated leg which is shorter?

A

hip fracture

20
Q

how do you clsasify hip fractures?

A

intracapsular and extracapsular

21
Q

which hip fracture can the blood supply to the femoral head be disrupted ?

A

intracapsular

22
Q

risk of what with intracapsular?

A

AVN and non union

23
Q

the two intra capsular fractures?

A

femoral head or neck fracture

24
Q

exrta capsular fractures?

A

intertrochanteric

subtrochanteric

25
Q

treatment of intracapsular

A

replacing femoral head
hemi arthroplasty
or total hip replacement

26
Q

/extracapsular fracture - should this cause AVN

A

no - they have a high union rate

27
Q

how do you treat an extra capsular fracture ?

A

compression or dynamic hip screw

28
Q

one of slowest bones to heal in body?

A

tibia

29
