fracture in region 1

A

have to stabilise the phalanges
o Little polster, but even surface (about 1 cm cotton wool)

16
Q
  • Simple
A

– little or no bone displacement

17
Q
  • Compund –
A

fracture ruptures the skin and bone protrudes

18
Q
  • Green stick
A

– occurs mostly in foals whose bones have not calcified or hardened

19
Q
  • Transverse
A

– crack perpendicular to long axis of the bone – displacement may occur

20
Q
  • Oblique
A

– diagonal crack across the long axis of the bone

21
Q
  • Spiral
A

– diagonal crack involving a “twisting” of the bone about the longitudinal axis

22
Q
  • Comminuted
A

– “crushing” fracture – more common in adults

23
Q
  • Impacted
A
24
Q

Avulsion

A

– fragment of bone is pulled away by tendon

25
Q
  • Depressed
A

– broken bone is driven up into the other
