Anterior cervical hybrid fusion and arthroplasty

Cervical disc arthroplasty may not be suitable for patients with symptomatic multilevel cervical disc degeneration given its relatively narrow indication. A long-construct fusion, however, may not be optimal given the prevalence of adjacent segment pathology following fusion. Moreover, patients may have varying degrees of disc degeneration, some of which may be adequately addressed by arthroplasty rather than fusion. Hybrid surgery (HS), which involves the combination of ACDF and CDA, has been increasingly utilized over fusion alone for patients with symptomatic multilevel disc degeneration. The combination of fusion with arthroplasty aims to preserve segmental motion at the index levels while minimizing adjacent-level hypermobility compared to ACDF alone.
