Extrication, immobilization and radiologic investigation of patients with cervical spine injuries.

Most cervical spine injuries are due to motor vehicle accidents. Proper extrication of the victims is vital; the ideal device should be easily assembled and applied, should facilitate removal of victims from automobile seats without changing the body's position, must not hinder airway access or the performance of cardiopulmonary resuscitation, must accommodate all types of patients, including children and obese or pregnant patients, and must completely immobilize the patient, especially if hyperextension is suspected. Current methods of immobilization, such as the use of a soft collar and sandbags, allow neck extension; the short board protects against extension but interferes with airway access. Newer devices are discussed in this article. Injuries of the upper cervical spine are less common but more serious than those of the lower portion and usually involve the vertebral arch. Radiologic examination of the first and second cervical vertebrae and the seventh cervical and first thoracic vertebrae should be emphasized. If lateral and anteroposterior views do not reveal abnormal findings and injury is still suspected, oblique views and computed or conventional tomography should be used. Cervical spinal cord injuries can be minimized or prevented if proper early management is applied.
