Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Economic evaluation of a behavioral-graded activity program compared to physical therapy for patients following lumbar disc surgery.
An economic evaluation was conducted alongside a randomized controlled trial. ⋯ This study concludes that there are no differences between the two treatment conditions on any of the clinical outcome measures but that behavioral-graded activity is associated with higher costs. Consequently, there is no reason for the implementation of behavioral-graded activity as the standard treatment for patients following lumbar disc surgery.

Prospective cohort study. ⋯ Low back pain was a dynamic process with high rates for incidence, recurrence, and recovery. General health and work-related physical and psychosocial factors influenced both the incidence and recurrence of low back pain. The incidence and recurrence of low back pain depend strongly on the recall period of low back pain and the time-window of investigation.

Comparative Study
Biomechanical comparison of anterolateral plate, lateral plate, and pedicle screws-rods for enhancing anterolateral lumbar interbody cage stabilization.
A repeated measures in vitro flexibility experiment was performed in calf spines. ⋯ Anterolateral or lateral lumbar plating increases stability significantly compared to stand-alone interbody cage fixation. These findings support anterolateral or lateral plate fixation as a potential clinical alternative to pedicle screws-rods in this role and may obviate the need for combined anterior and posterior approaches when spinal instability exists.
