Study summary

Prospective, multicenter non comparative and observational study (post-market clinical follow-up).

Patients operated with PASS OCT® manufactured by MEDICREA® INTERNATIONAL between July 2016 and July 2017.

The inclusion period will be 12 months and the follow-up 24 months

Read the detailed description

The primary endpoint is to evaluate the safety of the PASS OCT® system.

The secondary endpoints are to analyze the efficacy of the system with several point of view:

  • The quality of fusion and the time of fusion through X rays
  • the pain with VAS
  • the quality of life thanks to questionnaires: NDI (Neck Disability Index) and JOA for myelopathy
  • the daily of the patient: return to work, sport
  • the surgeon satisfaction.

Conditions studied

  • Intervertebral Disc Disease
