distal radius fractures

Question 1

buckle fractures are also called

Answer 1

torus fractures

Question 2

buckle fracture

Answer 2

are from an axial crush injury of the bone which shows no gap in the cortex on x-ray only a bulge where the impactation occurred

Question 3

what is a buckle fracture

Answer 3

incomplete fracture of the shaft of a long bone (most commonly the distal radius) that is characterised by bulging of the cortex

Question 4

greenstick fracture

Answer 4

are from an angulation force with a break in the periosteum on one side causing a bend and a fracture in the cortex of the other side which is incomplete

Question 5

management of buckle fractures

Answer 5

they are very stable and only require 3-4 weeks of splintage using plaster of paris

Question 6

management of greenstick fractures

Answer 6

splintage is stable but if significant deformity may be angulated and requires manipulation and casting particularly in older children

Question 7

in older children

Answer 7

salter harris type 2 fractures commonly occur around the distal radial physis

Question 8

complete distal radial fractures

Answer 8

may displace and angulate with dorsal displacement and angulation more common than ventral but the dorsal periosteum usually remains intact

Question 9

if complete fractures are stable management

Answer 9

casting

Question 10

if complete fractures are unstable

Answer 10

if still unstable after reduction may require wire stabilisation or plate fixation
