Instrumentation in lumbar fusion improves back pain but not quality of life 2 years after surgery

摘要

Background and purpose Instrumented and non-instrumented methods of fusion have been compared in several studies, but the results are often inconsistent and conflicting. We compared the 2-year results of 3 methods of lumbar fusion when used in degenerative disc disease (DDD), using the Swedish Spine Register (SWESPINE).
