Best evidence synthesis. ⋯ The Neck Pain Task Force undertook a best evidence synthesis to establish a baseline of the current best evidence on the course and prognosis for whiplash-associated disorders. We identify a number of gaps in the current knowledge, and provide recommendations for the conduct of future studies.

Retrospective case series of 16 consecutive patients. ⋯ Scoliosis surgery is frequently necessary in PWS and is associated with high rate of complications. These are often related to specific features of this syndrome the surgeon should recognize and consider.

An outcome study of patients with neurogenic claudication and/or sciatica with hidden stenosis, detected only by axial loading of the lumbar spine (ACE) but not at the traditional unloaded examination (psoas relaxed position) during computed tomography (CT) myelography or magnetic resonance imaging (MRI), followed up after surgery. ⋯ According to this study, the results of surgery in hidden lumbar stenosis only detected by axial compression in extension during CT or MRI, are convincing and comparable with the results of surgical treatment for stenoses diagnosed by unloaded examinations.

Biomechanical. ⋯ This first reported technique of posterior element vertebroplasty may increase the indications and success for patients with decreased BMD who seek an interspinous implant such as the X STOP. A possible role may exist in increasing the effectiveness of such devices. However, clinical trials have yet been performed. These results demonstrate that PMMA injection in the spinous processes is effective in increasing resistance to compressive forces in an X STOP model.

This study was designed to verify the hypothesis of a constant, antidromic activation of fibers traveling along peripheral sensory nerves during spinal cord stimulation (SCS). ⋯ The authors hypothesize that this antidromic activation could represent a possible antalgic mechanism of SCS in patients with peripheral neuropathic pain, but further neurophysiological studies will be needed to elucidate this hypothesis.
