Management of cervical spine deformity after intradural tumor resection.

Management of intradural spinal tumors requires posterior decompressive techniques. Cervical spine deformity secondary to sagittal and/or coronal imbalance after a laminectomy may result in significant cervical pain and functional deterioration, as well as neurological deficits in the most severe cases. In this paper, the authors discuss the management of cervical spine deformity after intradural tumor resection, with emphasis on the surgical strategies required to reestablish acceptable cervical spine alignment and to correct postoperative deformity. In general, after an oncological evaluation, assessing the alignment, extent, and flexibility of the deformity is mandatory before surgical planning. Rigid deformities require an osteotomy and, most often, combined approaches to restore cervical alignment. Flexible deformities can often be treated with a single approach, although a circumferential approach has its advantages.
