Anterior cervical corpectomy for the treatment of complex cervical lesions.

Instability and stenosis of the cervical spine have been treated by posterior decompression and anterior decompression with fusion. In this study the authors evaluate the results obtained in 31 patients who underwent anterior cervical corpectomy for compressive or unstable lesions of the cervical spine. Operative level, preoperative and postoperative symptoms and physical findings were assessed. Twenty-seven patients had preoperative neurologic symptoms and signs, including alterations in sensation, motor findings and reflexes. The average follow-up was 12 months, average number of disc spaces excised was 2.5 and average number of vertebral bodies excised was 1.6. With respect to relief of pain, results were good or excellent in 27 patients. All patients but one had union of the bone graft. No neurologic deterioration occurred. The authors believe that patients with compressive lesions of the cervical spine can benefit from anterior cervical corpectomy with fusion and that complications are minimal.
