Detailed Description:

This is a prospective randomized multi-center clinical trial to assess the safety and efficacy of the investigational device, Cervical I/F Cage for fusion in one or two adjacent levels of the cervical spine. Patients will be randomly assigned in a ration of 1:1 between the investigational and control groups.

Comparison: The device will be compared to a control group consisting of the 3 accepted standard of care treatments (autograft, autograft with an anterior plate, or allograft with an anterior plate). For two level fusions, the control group will be limited to autograft with a plate or allograft with a plate. Based on the current literature, it is believed that there is no difference between the three treatments in terms of clinical success, fusion success, or safety issues. However, amongst the investigators there are preferred treatments. Each investigator will choose one or more of the control treatments at study initiation. Patients will then be randomized in a 1:1 Cage:control randomization schema. Approximately 240 subjects will be enrolled at 20 sites. Eligible patients will have symptomatic degeneration of one or two adjacent cervical discs, have failed six weeks of non-surgical treatment, have sufficiently severe enough symptoms to warrant surgery, and have had no prior fusion surgery on the cervical spine.
