Randomized Controlled Trial Clinical Trial
Long-term functional outcome of pedicle screw instrumentation as a support for posterolateral spinal fusion: randomized clinical study with a 5-year follow-up.
A prospective randomized clinical study with a 5-year follow-up. ⋯ The long-term functional outcome of posterolateral spinal fusion improved significantly for boththose with and without pedicle screw instrumentation, with a global 70% satisfaction reported by the patients. Patients with isthmic spondylolisthesis Grades 1 and 2 with noninstrumented fusion had superior long-term outcomes after posterolateral spinal fusion in comparison with an instrumented fusion. In contrast, patients diagnosed as having primary degenerative instability improved significantly when the posterolateral fusion was supported by instrumentation. In actuality, pedicle screw instrumentation increased reoperation rate compared with noninstrumented posterolateral fusion.

Randomized Controlled Trial Comparative Study Clinical Trial
Characteristics of patients with chronic low back pain selected for surgery: a comparison with the general population reported from the Swedish lumbar spine study.
A group of surgical candidates with chronic low back pain was compared with a random sample of the general population. ⋯ The surgical candidates in the current study resembled the average Swedish citizen with back pain. Although selected for treatment because of symptom severity, they did not otherwise differ substantially from the general population with back pain. On the contrary they unexpectedly were affected only a little by depressive symptoms, distinguishing them from patients with chronic low back pain in pain clinics and rehabilitation centers. Therefore, the results of the this outcome study are not generally applicable to every patient with chronic low back pain.

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.

Randomized Controlled Trial Comparative Study Clinical Trial
Effectiveness of four conservative treatments for subacute low back pain: a randomized clinical trial.
A randomized, assessor-blinded clinical trial was conducted. ⋯ For subacute low back pain, combined joint manipulation and myofascial therapy was as effective as joint manipulation or myofascial therapy alone. Additionally, back school was as effective as three manual treatments.

Randomized Controlled Trial Clinical Trial
Effectiveness and cost-effectiveness analysis of neuroreflexotherapy for subacute and chronic low back pain in routine general practice: a cluster randomized, controlled trial.
A cluster randomized, controlled trial was performed. ⋯ Referral to neuroreflexotherapy intervention improves the effectiveness and cost-effectiveness of the management of nonspecific low back pain.
