A

ORIF

36
Q

What is a Barton’s fracture?

A

Intra-articular fracture of distal radius- carpal bones sublux and break off part of rim.
Can be volar or dorsal

37
Q

How do you treat a Barton’s fracture?

A

ORIF

38
Q

What is a comminuted intra-articular distal radius fracture?

A

Very traumatic and damaging fracture of radius

39
Q

How do you treat a comminuted intraarticular distal radius fracture?

A

External fixation

40
Q

What normally causes a scaphoid fracture?

A

FOOSH

41
Q

How does a scaphoid fracture present?

A

Tenderness in anatomical snuff box
Pain on compression
Difficult to see on XR therefore splint and asses in 2 weeks

42
Q

How do you treat a fractured scaphoid?

A

Undisplaced- Cast for 6-12 weeks

Displaced- Compress and screws

43
Q

What complications can occur with a broken scaphoid?

A

Due to poor blood supply can un-union and AVN.

44
Q

What are the 6 hand injuries we need to know

A
Phalangeal fractures
Metacarpal fractures
Flexor tendon injury
Penetrating hand injury
Extensor tendon injury
Mallet fracture
45
Q

How do you treat phalangeal fractures?

A

Strap to neighbours

If angles will need manipulated under ring block

46
Q

How do you treat metacarpal fractures?

A

3rd, 4th and 5th treat conservatively

5th tend to angle therefore strap digit to neighbour

47
Q

What is a special form of metacarpal fracture?

A

Fight bite

48
Q

What is the danger with fight bite?

A

Caa get oral bacteria in MCP capsule giving septic arthritis or disrupt extensor mechanism

49
Q

What is a major problem with flexor tendon injury?

A

Potential for damage to nerves and arteries

50
Q

What tendons can be damaged in flexor tendon injury?

A

FDS
FDP
FPB

51
Q

How do you treat flexor tendon injury?

A

Repair and splint in flexed position

52
Q

What is mallet finger?

A

Avulsion of extensor tendon from its insertion into terminal phalanx

53
Q

How does mallet finger occur?

A

Forced flexion of extended DIP joint

54
Q

How does mallet finger present?

A

Pain
Droop at DIP
Inability to extend DIP

55
Q

How do you treat mallet finger?

A

Hold extended for 4 weeks

56
Q

How do you treat extensor tendon injury?

A

If more than 50% then requires surgical repair with splint in extension for 6 weeks.
Flexion may cause healing failure

Q

How do you treat penetrating hand injuries

A

Repair damaged tendons etc
