Initial closed reduction of cervical spine fracture-dislocation injuries.

STANDARDS: There is insufficient evidence to support treatment standards. GUIDELINES: There is insufficient evidence to support treatment guidelines. Early closed reduction of cervical spine fracture-dislocation injuries with craniocervical traction is recommended to restore anatomic alignment of the cervical spine in awake patients. Closed reduction in patients with an additional rostral injury is not recommended. Patients with cervical spine fracture-dislocation injuries who cannot be examined during attempted closed reduction, or before open posterior reduction, should undergo magnetic resonance imaging (MRI) before attempted reduction. The presence of a significant disc herniation in this setting is a relative indication for a ventral decompression before reduction. MRI study of patients who fail attempts at closed reduction is recommended. Prereduction MRI performed in patients with cervical fracture dislocation injury will demonstrate disrupted or herniated intervertebral discs in one-third to one-half of patients with facet subluxation. These findings do not seem to significantly influence outcome after closed reduction in awake patients; therefore, the usefulness of prereduction MRI in this circumstance is uncertain.
