Randomized Controlled Trial
Effect of intervertebral disc height on postoperative motion and outcomes after ProDisc-L lumbar disc replacement.
Retrospective study of patients enrolled in prospective randomized Food and Drug Administration trial. ⋯ Patients with greater disc collapse benefit more in ROM from a total disc replacement. The optimal range to maximize ROM for postoperative anterior disc height is 16 mm to 18 mm. This optimal range did not translate into better clinical outcome at 2 years follow-up.

Randomized Controlled Trial
Correlation of measures of pain, function, and overall response: results pooled from two identical studies of etoricoxib in chronic low back pain.
Assessment of correlation of measures of low back pain (LBP) using data pooled from 2 identical studies. ⋯ In this study, the RMDQ, LBPI VAS, and PGART showed a high degree of correlation in measuring response to therapy in LBP, suggesting clinicians may be able to simplify assessments.

Randomized Controlled Trial
Effects of two guideline implementation strategies on patient outcomes in primary care: a cluster randomized controlled trial.
Cluster randomized controlled trial. ⋯ Active implementation of the German LBP guideline results in slightly better outcomes during 6 months follow-up than its postal dissemination. Results are more distinct when practice nurses are trained in motivational counseling.

A retrospective study. ⋯ The impact of ASD on clinical outcome after fusion showed a significant correlation, especially with the ASD after multiple-segments fusion. Careful attention is needed in multiple-segments fusion such as degenerative lumbar deformity.
