title: Spinal instability and the log-rolling maneuver.
abstract: Immobilization of the spine is of prime concern during transportation of trauma patients to prevent neurologic compromise. In an attempt to study certain techniques of prehospital thoracolumbar spine immobilization, we radiographically evaluated the motion of the thoracolumbar spine in a volunteer with a stable spine, a cadaver with an unstable thoracolumbar spine, and a patient with a T12-L1 fracture dislocation. Both the backboard and the Scoop stretcher offered adequate stabilization for thoracolumbar spine instability. The logroll maneuver presented the greatest possibility for movement of the spine at the unstable thoracolumbar segment.
