Background: There have been rare cases of traumatic cervical spondyloptosis without neurological compromise. We report another case and provide a review of the literature, with a focus on appropriate management.
Case description: A 60-year-old male rode his bicycle into a stationary semi-truck. He reported initial bilateral upper extremity paresthesias that resolved. Imaging demonstrated C7 on T1 spondyloptosis. Traction did not achieve reduction and a halo was applied. Subsequently, he underwent posterior decompression C6-T1, reduction via bilateral complete facetectomies at C7, and fixation from C4 to T2 fixation. Afterward, an anterior C7-T1 fixation occurred, where exposure was performed through a midline sternotomy. Postoperatively, he woke up with baseline motor and sensory examination in his extremities. He did exhibit voice hoarseness due to paralysis of the left vocal cords. He was discharged home 3 days after surgery. At 6 months follow-up, there was a progressive improvement of the left vocal cords to slight paresis; dynamic X-rays demonstrated no instability with good fusion progression.
Conclusion: Traumatic cervical spondyloptosis without neurological compromise is a rare and challenging scenario. There is a concern for neurologic compromise with preoperative traction, but if specific posterior elements are fractured, the spinal canal may be wide enough where the concern for disc migration is minimal. For patients who have not been reduced preoperatively, a posterior approach with initial decompression to widen the canal, before reduction, appears safe. This scheme may avoid an initial anterior approach for decompression, necessitating a 3-stage procedure if circumferential stabilization is pursued.
