Design outcomes

Primary

MeasureTime frame
Performance is evaluated by the success (yes/no) of the fusion by Functional X-ray Analysis (FXA) at 6 months.

Secondary

MeasureTime frame
The secondary endpoints concern clinical safety and performance. Safety will be measured with: • Assessment of AE • A SAE related to the medical device • Reoperation Performance will be measured with: • Decrease in Visual Analog Scale for Pain (VAS) for back and leg by 3/10 or more at 24 months from the pre-operative value. • Improvement in Oswestry Low Back Disability (ODI) of 15 or more at 24 months from the pre-operative value. • Evidence of bridging trabecular bone between the involved motion segments.
