Retrospective Analysis of Patients Implanted With 2 Levels of Prodisc® C Vivo Devices

A Multicenter, Retrospective Analysis to Evaluate Radiographic Outcomes and Safety Profiles Along Prospective Follow-Up Periods for Patients Implanted With 2 Levels of Prodisc® C Vivo Devices.

The objective of the study is to evaluate the safety and post-operative performance profile of the prodisc® C Vivo after implantation in comparison to the relevant clinical literature.

The primary objective of the study is to evaluate (estimate) the post-operative performance of prodisc® C Vivo overall, after implantation. Post-operative device performance will be estimated using Patient Reported Outcomes (PROs) and radiographic data derived from the patient's surgical charts and medical history.

The secondary objectives of this study are to assess:

• patients with no secondary surgical interventions (SSIs), i.e. revision, removal, re-operation, supplemental fixation at the index level(s)
• the rates of ADEs inclusive of intraoperative and post-operative complications
• Patient Reported Outcomes (PROs)
• Outcome self-assessment of Health Survey (SF 12 or 36 as available)

Inclusion Criteria:

• In order for a patient's data to be included in this study, he/she has to meet the indications and not possess any of the specific or general contraindications listed in the Instructions For Use (IFU).
• They must provide written informed consent with appropriate documentation noted in source documentation (prospective cohort only).

Exclusion Criteria:
