ABSTRACT
This chapter addresses the option of conversion of the index-level device to arthrodesis, commonly referred to as anterior cervical discectomy and fusion. Anterior decompressions in the cervical spine have traditionally been complemented by a reconstruction following the removal of pathological material such as cervical disc, osteophytes, and degenerative ligament pathology. One goal of cervical disc replacement is retention of index-level motion, a phenomenon that is commonly measured with radiographs in the clinical setting. Revision of anterior arthroplasty, as described for the indications noted herein, should be approached with the expectation of achieving solid arthrodesis at the operative level. Neurological assessments continue, consistent with revision anterior spinal surgery. Immobilization is considered at the discretion of the treating surgeon. Discharge to the ambulatory setting is made in the mobile patient who has appropriate swallowing function, good pain control, and a stable neurological examination.
