Finally, Gatz et al.

The study was approved as a medical assessment registry without request for patient consent.
The Swiss Federal Office of Public Health demanded a nationwide health technology assessment registry for cervical and lumbar total disc arthroplasty and for balloon kyphoplasty (BKP) to make a decision about reimbursement of these interventions.
