Norwegian Arthroplasty Register - NAR


THE NORWEGIAN ARTHROPLASTY REGISTER . The Norwegian Arthroplasty Register started registration of total hip replacements in 1987.

In 1994, registration was extended to include insertion of all types of artificial joints.

The main reason for establishing a nation-wide register was that throughout the 1970ies, new hip implants had been introduced without documentation from clinical studies.

After being used for more than 10 years, several of the prostheses were identified with high failure rates, but had at the time already been used on large numbers of patients.

The main purpose of the register is to function as a surveillance tool to identify inferior implants as early as possible.

The orthopaedic surgeons provide information on all primary joint replacements, including an accurate description of the different parts of the implant.

If the prosthesis is later revised (the implant is removed or exchanged), the register receives a new report with information about the reason for and the type of revision. .
