Fracture description depends on the class of bone and the direction of the fracture line
A long bone fracture is described according to its direction in relation to the shaft of the bone
Bones and fractures
There are 4 anatomical classes of bone - long, short, flat and irregular. Description of a bone fracture depends on the class of bone and the direction of the fracture line.
'Long bone' fractures
Long bone fractures are described with reference to the direction of the fracture line in relation to the shaft of the bone. For example, a fracture passing perpendicular across the bone shaft is described as 'transverse'.
Other fractures passing across a long bone include, 'oblique' and 'spiral' fractures.
If a fracture passes along the shaft of a long bone then it can be described with reference to the plane in which it passes, for example coronal or sagittal.
