Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Evaluate the safety associated with the use of the investigational implant during long term follow up	The DIAM device, specifically at long-term follow-up. A subject is considered to be a long-term success if they are free from serious device-related adverse events through final follow-up.; Secondary surgical intervention for treatment failure (i.e. recurrence of pain or functional impairment) without other serious device-related adverse event is not considered to be a serious device-related adverse event for the purposes of the primary endpoint.	5-10 years after implantation
Secondary	Back Pain evaluation	Composite overall success consisting of: Pain/disability (Oswestry) success (=15 pt. improvement relative to baseline) No serious adverse event is classified as "implant-associated", "procedure associated" or "implant-/surgical procedure associated." No additional surgical procedure at the involved level is classified as a failure.	5-10 years after implantation
Secondary	Back Pain evaluation	Change in back pain score compared to baseline	5-10 years after implantation
Secondary	Back Pain evaluation	Back pain success calculated as: Pre-treatment Score - Post-treatment Score > 0 (Score = pain intensity + pain frequency)	5-10 years after implantation
Secondary	Back Pain evaluation	SF-36/RAND-36 success calculated by: PCSPost-tx - PCSPre-tx > 0	5-10 years after implantation
