Late instability in cervical spine fractures secondary to laminectomy.
Of 256 patients with a major spinal cord injury as a result of fracture of the cervical spine, 38 per cent had a laminectomy. Three months after injury, 33 per cent of the patients with laminectomy  required fusion for instability compared to 22 per cent of the nonlaminectomy group. There were no cases of late instability in pure flexion or extension fracture groups. Ninety per cent of the late instability cases were in the groups with hyperflexion and flexion compression fractures. Laminectomy should be avoided for these fractures, but early fusion may be necessary to prevent progressive deformity.
