Traumatic spondyloptosis of the cervical spine: A case report and discussion of worldwide treatment trends.

BACKGROUND

Cervical spondyloptosis is defined as the dislocation of the spinal column most often caused by trauma. Due to compression or transection of the spinal cord, severe neurological deficits are common. Here, we review the literature and report a case of traumatic C5-6 spondyloptosis that was successfully treated using an anterior-only surgical approach.

METHODS

The patient presented with quadriplegia and absent sensation distal to the C5 dermatome following a rollover motor vehicle accident. The preoperative American Spinal Injury Association Impairment Scale was A. Computed tomography of the cervical spine revealed C5-6 spondyloptosis, lamina fractures on the right side at the C3-4 level, and widened facet joint on the right side at C6-7.

RESULTS

The patient underwent cervical traction and anterior cervical discectomy and fusion at the C5-6, C6-7 levels; no 360° fusion was warranted. Six months postoperatively, the patient remained quadriplegic below the C5 level.

CONCLUSION

Presently, no consensus is present regarding the best treatment for spondyloptosis. Worldwide, the 360° approach is the most commonly used (45%), followed by anterior-only surgery (31%) and posterior-only surgery (25%). The surgical choice depends upon patient-specific features but markedly varies among geographical regions.
