Wedge compression fracture

Discussion:

Wedged compression fractures

They are the most common type of lumbar fractures.

Isolated failure of the anterior column. Wedge-shaped vertebral body.

Mechanism of injury: hyperflexion and axial load.

These fracture are rarely associated with neural injury.

The main differential is Burst fracture (fracture of the anterior and middle columns with or without posterior column fracture, usually associated with neural injury)

The importance of differentiating compression from burst fractures lies in the higher frequency of neurological deficits associated with the latter.
