Q

distal radius greenstick fracture

A

failure of 1 cortex in compression and other cortex extension

18
Q

Managing buckle, greenstick and complete forearm fractures

A
B = cast for 3-4weeks
G = cast for 4-6 weeks 
C = cast +/- KW 6 weeks
19
Q

knee trauma differential

A

infection - neoplasm - inflammatory arthropathy - apophysitis - hip?foot? - haemophilia

20
Q

bony injury of knee areas

A

physeal/metaphyseal
tibila tubercle or spine
patellar fracture or dislocation
referred

21
Q

femoral or tibial - physeal injury of knee?

A

femoral 2: tibial 1

22
Q

Why is femur more susceptible to physeal injury?

A

distal femur below physis, prox tibia below physis

femur grows 11mm/yr, tibia 6mm/year

23
Q

causes of physeal knee injuries

A

hyperextension
vascular injury
varus

24
Q

treating knee physeal injury

A

immobilise with cast, percutaneous fix, ORIF

25
Q

managing physeal arrest

A

monitor - harris lines, angulation and length
resect bar, epiphysiodesis (complete or contralateral)
corrective osteotomy

26
Q

What ligament does the tibial spine overlap with?

A

ACL

27
Q

Meyers and mckeever tibial spine fracture and treatment

A

1 - undisplaced = long leg cast
2= hinged = long leg cast or ORIF
3 - displaced = ORIF

28
Q

ogden - tibial tubercle fracture

A

1 = distal avulsion
2 = to proximal tibial physis
3- to proximal tibial physis and into joint

29
Q

patellar fracture and treatment

A

rare - cartilaginous to age 4
undisplaced = cylinder cast
displaced = ORIF

30
Q

patellar dislocation risk factors

A
tibial external rotation 
patella alta 
laxity 
poor vastus medialis oblique
Q angle
femoral anteversion
31
Q

managing patellar dislocation

A

cast 2/52 ligament
mobilise
VMO exercises
repair VMO, lateral release,

32
Q

osteochondral lesions imaging

A

plain films - tunnel view - and MRI

33
Q

osteochondral lesions type 1,2,3 management

A
1 = cartilage intact and immobilise 
2 = flap and 3=fragment - drill/fix
34
Q

ankle growth/year

A

6mm

35
Q

Ottawa rules

A

ankle - lateral and medial view

bony tenderness and unable to weight bear

36
Q

additional views for the ankle to not miss lesions

A

oblique and mortise

37
Q

Managing SHI fractures - ankle

A

displaced <3mm = POP 6

>3mm = MUA, POP 6

38
Q

SH2 ankle fracture management

A

<3mm POP 4+2, >3mm = MUA, POP

39
Q

managing SH3

A

undisplaced POP 6, displaced - open reduction and screws

40
Q

managing SH4

A

ORIF and monitor for growth arrest

41
Q

tillaux

A

external rotation, SH3, open or closed reduction

42
Q

triplane

A

external rotation, SH3 on AP and SH2 on lat = SH4

CT ORIF
