Abstract
A report on 3 patients undergoing total spondylectomy of the C2 vertebra for tumor and the technique for C1-3 reconstruction. To illustrate the feasibility of complete resection of the C2 vertebra with preservation of the vertebral arteries and cervical nerve roots.
Total spondylectomy provides improved progression free survival in many patients with locally aggressive spinal tumors. However, the perceived technical demands of effectively preserving both vertebral arteries, maintaining cervical nerve roots, and biomechanical reconstruction of the cranial-cervical junction often dissuades surgeons from carrying out total spondylectomy of the C2 vertebra.
A review of 3 patients undergoing total C2 spondylectomy for tumor (thyroid adenocarcinoma, chordoma, and solitary plasmocytoma) was done. The surgical procedure that was undertaken and the technique used are described.
Postoperatively, all 3 patients had uneventful postoperative recovery with gradual improvement in their neurologic functions. Preservation of bilateral vertebral arteries and all cervical nerve roots is feasible when carrying out intralesional total spondylectomy in patients with C2 vertebral body tumors and should be considered in patients thought to benefit from total C2 vertebra excision.
In an attempt to augment construct stability and provide anterior column load sharing, we have used mesh cage and iliac crest graft between C1 and C3 held in place with a short cervical plate without complications
