结局指标
主要结局
Clinical Composite Success
时间窗: Data through 24 months gathered in IDE (NCT03123549; start date 4/1/17). This PAS (start date 8/1/21) followed the same patient cohort through 60 months post-op. Comparison data from historical controls up to 60 months post-op is also reported
Individual success for Simplify Disc was defined as follows: * Neck Disability Index (NDI) score improvement of at least 15 points from pre-operative; * Maintenance or improvement in neurological status; * No serious adverse event classified as implant associated or implant/surgical procedure associated; and * No additional surgical procedure classified as a "failure."
