Randomized Controlled Trial Clinical Trial
Should we give detailed advice and information booklets to patients with back pain? A randomized controlled factorial trial of a self-management booklet and doctor advice to take exercise for back pain.
Randomized controlled factorial trial. ⋯ Doctors can increase satisfaction and moderately improve functional outcomes in the period immediately after the consultation when back pain is worst, by using very simple interventions: either by endorsing a self-management booklet or by giving advice to take exercise. Previous studies suggest that simple advice and the same written information provide reinforcement. This study supports evidence that it may not be helpful to provide a detailed information booklet and advice together, where the amounts or formats of information differ.

Comparative Study
Transpedicular screw placement: image-guided versus lateral-view fluoroscopy: in vitro simulation.
In vitro evaluation of monitoring screw placement using an image-guided system compared with the routine use of an image intensifier. ⋯ In vitro computer-aided pedicle screw insertion is more accurate than lateral-view fluoroscopy in the thoracic spine. The main disadvantage is the time consumption compared with that required by lateral-view fluoroscopy. The total time of the surgical operation should be decreased with the future development of these techniques.

Biomechanical evaluation of stand-alone interbody fusion cages in the cervical spine.
An in vitro biomechanical investigation of the immediate stability in cervical reconstruction. ⋯ The increased motion adjacent to C4-C5 may provide an argument for acceleration of disc degeneration. From the biomechanical point of view, this study suggests that the cervical interbody fusion cage should be supplemented with additional external or internal supports to prevent excessive motion in flexion-extension.

A retrospective case study of patients with intraspinal cyst having a distinct connection with the corresponding intervertebral disc. ⋯ Eight cases of intraspinal cysts communicating with the intervertebral disc presenting symptoms identical to those of disc herniation are presented. Because all cysts were connected to the corresponding disc and the development of the cyst was assumed to be related to underlying disc injury, it is proposed to name this clinical entity discal cyst.

Comparative Study
A comparison of fear-avoidance beliefs in patients with lumbar spine pain and cervical spine pain.
A prospective consecutive cohort study of patients with cervical spine pain and patients with lumbar spine pain referred to an academic medical center. ⋯ The associations among fear-avoidance beliefs, pain intensity, and disability differed between patients with cervical spine pain and patients with lumbar spine pain. Fear-avoidance beliefs were significantly different in subgroups of patients.
