Modern Alternatives and Techniques for One-Level Discectomy and Fusion

Monosegmental cervical spondylosis with radiculopathy requiring operative intervention responds well to anterior disc excision and fusion with autograft. However, there is a 20% to 25% morbidity from the donor site. Several new surgical techniques using biomechanical spacers or internal fixation have been developed that can be used with local bone or allograft, thus eliminating donor site morbidity. Surgical outcomes are comparable with those of traditional anterior cervical discectomy and fusion.
