Randomized Controlled Trial
Clinical outcomes of 3 fusion methods through the posterior approach in the lumbar spine.
This prospective randomized study compared 3 fusion methods: posterolateral fusion (PLF), posterior lumbar interbody fusion (PLIF), and PLIF combined with PLF (PLF+PLIF). ⋯ No significant differences in clinical results and union rates were found among the 3 fusion methods. PLIF had better sagittal balance than PLF. PLIF without PLF had advantages of the elimination of donor site pain, shorter operating time, and less blood loss.

The position of a needle tip displayed on a navigation system after transpedicular introduction into a vertebral body is compared with the real position of the needle tip when using a direct navigation coupling between a three-dimensional rotational X-ray (3DRX) system and a navigation system. ⋯ Accuracy of 3DRX-guided navigation is 2.5 +/- 1.5 mm in a clinically relevant setting, which is less than the accuracy determined in phantom experiments.

The present report describes treatment of enlarged lumbar epidural veins in a patient with Budd-Chiari syndrome presenting with intractable radicular and low back pain. ⋯ Inferior vena cava stenosis related to hypertrophied caudate lobe producing lumbar epidural venous engorgements should be considered as one of the causes of radicular and low back pain. We could obtain a favorable clinical outcome by handling the primary cause of the venous engorgement.

Multicenter Study
Validation of a minimum outcome core set in the evaluation of patients with back pain.
Prospective study of patients with subacute osteoporotic fracture (SOF) or chronic low back pain (CLBP). ⋯ These findings support the potential usefulness of the Core Set when respondent burden is a major concern. However, subscale scores need to be further tested in other populations before they can be widely recommended.

Randomized Controlled Trial Multicenter Study
Cost-utility analysis of physiotherapy treatment compared with physiotherapy advice in low back pain.
Economic evaluation alongside a pragmatic multicenter randomized controlled trial from the National Health Service (NHS) and societal perspective. ⋯ The results indicate no significant differences in either NHS costs or effects. However, the significantly higher out-of-pocket expenses incurred by patients receiving routine physiotherapy suggests that advice given by a physiotherapist should be considered as the first-line treatment for patients with this level of back pain disability.
