Post-traumatic cervical spondyloptosis: A rare entity with multiple management options.

Post-traumatic cervical spondyloptosis is a rare condition associated with high energy injuries, and to our knowledge only case reports are available. There are no universally accepted treatment paradigms for these cases and management is individualised according to the case and surgeon preference. We retrospectively analysed our management and clinical outcomes of this condition. From January 2007 to August 2014 we treated eight patients with cervical spondyloptosis at our institute. Only two patients had no neurological deficits; all the remaining patients had partial cord injury. Seven were treated surgically with preoperative traction followed by anterior cervical discectomy and fusion with fixation in three patients, and combined anterior and posterior fusion and fixation in four. Depending on the presence of anterior compression by a disc an anterior first or posterior first approach was advocated. All four combined anterior and posterior fusion and fixation patients needed to be turned more than once (540°). There was no neurological deterioration in any of the patients, as they either improved or remained stable neurologically. Post-traumatic cervical spondyloptosis is a challenging entity to manage. Surgery can be done safely with good clinical and radiological outcome and needs to be tailored to the individual patient.

Treatment strategies for lower cervical dislocation combined with facet locking / 中华创伤杂志

Objective To discuss the therapeutic options for treatment of subaxial cervical dislocation combined with facet locking. Methods There were 49 patients with cervical dislocations including 7 patients with dislocation at C3,4, 15 at C4,5, 14 at C5,6 and 13 at C6,7. Eleven patients were with old dislocation, with duration of dislocation ranging from 2 hours to 61 days. Neurologic status of the patients according to Frankel scale was graded A in 14 patients, grade B in nine, grade C in 10 and grade D in nine. All patients were treated surgically after closed reduction with skull traction. Results The successful reduction rate was 63% for fresh dislocation, with average improvement of 0.65 grade for spinal cord function. All bone grafts got fusion at four months after operation. Conclusion Therapeutic options are based on fresh or old dislocations, paraplegia or not, intervertebral disk injury severity, and reduction or not through traction for patients with lower cervical dislocations.
