Structural allograft implantation for thoracic spinal impalement.

Impalement injury is uncommon, with only occasional reports. Thoracic impalement injuries from falls are rarely seen in the emergency department, because most patients die at the scene of injury. We present an unusual case in which a patient survived a bilateral thoracic impalement injury and was successfully treated for the bleeding thoracic spinal defect with a method that used a structural ulnar allograft implantation.
