Anterior cervical corpectomy and fusion-derived adjacent segment disease managed via channel-repairing anterior endoscopic transcorporeal cervical discectomy: a case report.

Abstract

<h4>Background</h4>Management of anterior cervical corpectomy and fusion (ACCF)-derived adjacent segment disease (ASD) represented a challenge facing the surgeons.<h4>Methods</h4>A 41-year man diagnosed as C3-4 level ASD derived from C5-level ACCF surgery 13 years ago was admitted to the hospital for numbness and pain in the right shoulder and upper limb. Percutaneous full-endoscopic anterior transcorporeal cervical discectomy (PEATCD) was performed, and pre- and postoperative clinical and imaging data were collected.<h4>Results</h4>The operation was completed within 70 min, and no clinical or radiological complication was reported. The visual analog scale (VAS) score decreased from preoperative 5 points to postoperative 1 point. Numbness was relieved postoperatively and disappeared completely at postoperative 3 months. Imaging data indicated sufficient spinal cord decompression, good channel repairing and cervical alignment.<h4>Conclusions</h4>Channel-repairing PEATCD was successfully performed to treat ACCF-derived ASD, nevertheless, the long-term efficacy remained tracing and further clinical trials were needed to validate its efficacy.
