Anterior cervical spine fusion for unstable fractures.

We present in this report the operative method we have used in 7 cases of fracture-dislocation of the lower cervical spine. The technique includes partial resection of the fractured vertebral body, removal of the adjacent discs, excision of posteriorly displaced bone and disc and anterior interbody fusion between the three vertebrae. The latter is performed using a cortico-cancellous graft taken from the iliac crest and further stability is achieved by a small AO plate. All the cases started motion 48 hours after operation without further external support. Although 6 of the cases showed neurological improvement, this cannot be at this stage attributed to the surgical treatment. Nevertheless, none was made worse by the operation.
