Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Chronic low back pain and fusion: a comparison of three surgical techniques: a prospective multicenter randomized study from the Swedish lumbar spine study group.
A multicenter randomized study with a 2-year follow-up period and an independent observer was conducted. ⋯ All the fusion techniques used in the study could reduce pain and improve function in this selected group of patients with severe chronic low back pain. There was no obvious disadvantage in using the least demanding surgical technique of posterolateral fusion without internal fixation.
