Cervical spondylosis and degenerative disc diseases often lead to a compression of one or more nerve roots and/or the spinal cord resulting frequently in cervical radiculopathy and myelopathy. If non-surgical therapies fail, the most common form of treatment is an ACDF.2 However, this intervention is associated with a high rate of arthrodesis and a loss of segmental mobility. The consequences can be pseudo arthritis or adjacent segment degeneration (ASD).3,4
