Answer 2

Spiral

Question 3

Answer 3

Segmental

Question 4

(non-displaced and displaced)

Question 5

Answer 5

Linear

Question 6

What type of fracture is this?

Answer 6

Impacted

Question 7

What type of fracture is this?

Answer 7

Greenstick

Question 8

What type of fracture is this?

Answer 8

Comminuted

Question 9

What type of fracture is this?

Answer 9

Avulsion

Question 10

Which fracture is associated with dinner fork deformity?

Answer 10

Colles fracture

Question 11

What does displacement desribe?

Answer 11

The direction of translation of the distal fragment in a fracture

Question 12

What does angulation describe?

Answer 12

The direction in which the distal frament points towards and the degree of deformity

Question 13

Describe a Colles fracture

(which bone, intra- or extra-articular and direction angulation / displacement)

Answer 13

Distal radius

Dorsal displacement

Dorsal angulation

Question 14

What’s the classic history for a Colles fracture?

Answer 14

Fall onto outstretched hand

Question 15

Describe a Smith fracture?

(which bone, intra- or extra-articular, and angulation / displacement)

Answer 15

Distal radius, extra-articular

Volar / ventral displacement and angulation

Question 16

Smith’s fractures tend to be stable.

TRUE / FALSE?

Answer 16

False! Highly unstable

Question 17

Treatment of Smith’s fracture?

Answer 17

ORIF for all of them

If the fracture heals with flexion it will result in profound weakness and reduced grip strength

Question 18

What is a Barton’s fracture?

(which bone, intra- or extra-articular, and direction of displacement / angulation?)

Answer 18

Distal radial fracture

Intra-articular with subluxation or dislocation at the radio-carpal joint

Can be dorsal or volar

Question 19

Treatment of Barton’s fracture (and subluxation of carpals)?

Answer 19

ORIF with plate and scews

note: fracture is v unstable

Question 20

Describe a Galeazzi fracture

(which bone, and what is dislocated?)

Answer 20

Fracture of the radius (distal third)

Dislocation of the ulnar at the distal radio-ulnar joint

(note: if the radius is fractured in isolation, suspect dislocaiton of the distal R-U joint)

Question 21

Descibe a Monteggia fracture?

(which bone is fractured, and what is dislocated?)

Answer 21

Ulna is fractured

Dislocation of the radial head at the elbow

Question 22

What is a nightstick fracture and when might it occur?

Answer 22

Fracture of the ulnar shaft

(with no associated radial head dislocation)

Occurs after a direct blow to the ulnar shaft

Question 23

List three types of forearm fracture

Answer 23

Galezza: radial fracture with distal ulnar dislocation

Monteggia: ulnar fracture with radial head dislocation at the elbow

Nightstick: isolated fracture of the ulnar shaft

Question 24

Treatment of a forearm fracture?

The exception to this is for an isolated fracture with no dislocation (Nightctick fracture) - how would this be treated?

Answer 24

ORIF with plate and screws

Nightstick / isolated fracture: manage conservatively
