What is a secondary risk associated with a burst fracture?

A burst fracture is characterized by a break in the vertebra that results in fragments of bone being displaced in multiple directions, often leading to instability of the spine. The secondary risk associated with this type of fracture is the retropulsion of bony fragments. When a vertebral body bursts, pieces of bone can be pushed backward toward the spinal canal, potentially impacting or damaging the spinal cord and nerve roots. This movement of bone fragments can contribute to neurological deficits and creates an urgent need for intervention to stabilize the spine and prevent long-term complications.

While hemorrhaging in adjacent tissues, inadequate blood supply, and nerve compression syndrome can all be potential concerns in the context of spine fractures, retropulsion specifically highlights the mechanism of injury and its immediate implications for spinal stability and neurological function. Understanding the dynamics of how bony fragments may displace helps guide timely surgical or conservative management to mitigate risks following a burst fracture.
