Summary

In many countries a majority of patients with degenerative spondylolisthesis are operated on with decompression plus instrumented fusion, but the scientific evidence for adding fusion is controversial. To evaluate whether micro-decompression alone is as good as (non-inferior to) decompression plus instrumented fusion, a study with data from the Norwegian Registry for Spine Surgery was conducted, now the long-term follow up.
