Q

What are the principles of children’s fractures

A

Often simple, incomplete and heal quickly
Metabolically active periosteum
Cellular bone
Plastic

Fixation is not typically required
Do not over immobilise
Do not over treat

Radioulnar synostoss 
PIN injury
Superfifical radial injury`
18
Q

What are the management of distal radial fractures

A
Buckle cast- 3-4 weeks
Greenstick- cast 4-6 weeks
Complete cast
Risk for reminipulation
-complete fracyres
failed anatomcial reduction
Not B/E pop
19
Q

What are the differential diagnosis to knee trauma?

A
Infection
Inflammatory arthropathy
Neoplasm
Apophysis
Apophysitis
Hip
Foot
Sickle, heamophilia
Anterior knee pain
20
Q

What bony injuries occur during knee trauma?

A
Physeal/metaphyseal injuries
Tibial spine
Tibial tubercle
Patellar fracture
Sleeve fracture
Patellar dislocation
Referred pain
21
Q

What is involved in physeal injuries

A
Can be femoral or tibial
Capsuel and ligaments also involved
hyperextnesion causes vascular injury
Varus- CPN injury
SH not predictive
22
Q

What is the treatment for a physeal injury

A

Cast, immobolise
Percutaneous fix
ORIF articular diplacement
ROM early

23
Q

What is the treatment of physeal arrest

A
Monitor- harris lines, angulation and length
Resect bar
Complete epiphysoidesis
Contralateral epiphysiodesis
Corrective osteotomy
24
Q

What occurs during tibial spine injuries?

A
Overlap with ACL
Meyers and McKeever
I- undiscplaced
II hinged
III displaced
I/II long leg cast
II/III ORIF, AxIF
25
Q

What occurs during a patellar fracture

A

Rare- cartilagenous to age 4
Sleeve type
Undisplaced-cylinder cast
Displaced- ORIF

26
Q

Patella dislocation risk factors?

A
Laxity
Poor VMO
Q angle
Femoral antevesrion
Tibial external rotation
Patella alta
27
Q

How do you manage patellar dislocation

A
Controversial 
Cast- repair medial ligament
Mobilise- lateral release
VMO exercises- medial tib tubercle
SemiT tenodesis
28
Q

What are osteochondral lesions?

How are they treated?

A

Small fracture of the cartilage of the surface of the talus.
Single traumatic injuries that cause a fracture of the talus cartilage
Type I-cartilage intact- immobilise
Type II- flap/Type II fragment- drilling/fix

29
Q

How do youu diagnose anterior knee pain

A

diagnosis of exclusion
Inflammatory, neoplasm
Oschar schatts, SLJ?

30
Q

What is a risk in ankle fractutes

A

Physis is a plae of fracture

It is weaker than the ligaments and carries a risk of growth arrest

31
Q

What are the classifications of ankle injuries

A

Mehanistic- lauge hansen, dias-tachdjan

Anatomical-salterharris, vahvanene and aalto

32
Q

How are patients with ankle injuries assesed

A

History-mechanism
Deformity
Soft tissues
AP + lateral radiograpgs- ottowa rules

33
Q

What are the ottowa rules

A

X rays are not required unless:
There is pain in malloeolar zone
There is bone tenderness at posterior edge of lateral malleolus
Base of fifth metatarsal
Navicular
Inability to bear weight both immediately and in emergency department

34
Q

How do you manage an SH1 fracture

A

Displaced<3cm- pop 6

Displaced >3cm MUA, POP 6

35
Q

How do you manage an SH2 fracture

A

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

36
Q

How do you manage an SH3 fracture
